Title: Project: SSK revival
Post by: mkawa on Sun, 29 July 2012, 10:30:44
UPDATE 11.28
sorry, i've been super derelict in keeping this OP updated. here's the latest update on where this project is at: http://geekhack.org/index.php?topic=33430.msg724146#msg724146

<insert link to SSK wiki here>

I will be starting a community-driven project to revive the SSK, with limited help from Unicomp (as in they are not aware that this is happening, but they will be providing parts regardless :D)

Current status: there is a board en route to my CAD guy, who will disassemble, take measurements, and design a new machinable aluminum (or acrylic, depending) casing for the SSK BS internals. we are aiming for ease of manufacture and low target cost.

Project goal: brand new SSKs, constructed by hand, for everyone who wants one.

Is the goal to have a TKL BS board, or to have a replica of the SSK?

The first one seems more interesting, as we can customize it, and make it smaller.
Title: Re: Project: SSK revival
Post by: mkawa on Sun, 29 July 2012, 10:39:11
definitely the former. an aluminum replica of the original SSK casing would be prohibitively expensive, and defeat the purpose of a ground-up rethink.

i started a similar project at DT during the down time here. model F (capacitive BS) is my #1 switch choice, so i started with an XT and will re-use everything but the matrix and barrel plate - this to keep the cost as low as possible. already decided on a tenkeyless key layout. i would be very happy to help with this as there is quite a bit of overlap. my 2D CAD skills are pretty good.
Title: Re: Project: SSK revival
Post by: fartq on Sun, 29 July 2012, 11:41:00
interesting. your project is much more extensive, as you need to fab a pcb, barrel plate, etc. for this SSK project nearly all the internals are either directly available from unicomp or modifiable from parts that are. the scope of this project is largely limited designing a new economical (and probably smaller) casing for the standard SSK internals.
Title: Re: Project: SSK revival
Post by: Djuzuh on Sun, 29 July 2012, 11:44:30
unicomp has all the SSK internals for sale ? :o
Title: Re: Project: SSK revival
Post by: fartq on Sun, 29 July 2012, 11:48:11
not directly, but with some relatively minimal hacking, internals can be constructed from what they have available or tooling for.
Title: Re: Project: SSK revival
Post by: wcass on Sun, 29 July 2012, 14:17:06
the XT had separate barrels and barrel plate, so all i need is a plate with holes cut and will reuse the old barrels. this allows for lots of layout options. i ordered a prototype plate last week ($25 + ship). i expect that the plates would be much cheaper if i ordered 20 or so.

 i was planning on doing a compact 16x5 layout next. i had an idea of replacing the bottom membrane with very thin PCB. each column of 5 keys would have one of these http://www.digikey.com/product-detail/en/MMBD4148PLM-7/MMBD4148PLMDICT-ND/1964793 (http://www.digikey.com/product-detail/en/MMBD4148PLM-7/MMBD4148PLMDICT-ND/1964793) to give full NKRO. putting it at the top of the column or on the back will keep it out of the way of the hammers.
Title: Re: Project: SSK revival
Post by: fartq on Sun, 29 July 2012, 14:51:19
this is very interesting. i suspect there will be overlap between the projects. any way to move your project thread over here? :D

Post by: wcass on Sun, 29 July 2012, 17:59:30
the XTant project is established at DT, but i would be happy to discuss/plan the compact keyboard project here.

what do you think of this layout? the keys left of the left arrow and up arrow are stepped "caps lock" keys. this should help isolate the arrow block.

Post by: hashbaz on Sun, 29 July 2012, 18:48:44
I support these projects and can't wait to get my hands on one or both.  A custom BS board would be even cooler than a vintage SSK.

The layout above needs a tilde key IMO. ;)

Title: Re: Project: SSK revival
Post by: wcass on Sun, 29 July 2012, 19:31:28
The layout above needs a tilde key IMO. ;)
i believe that all keyboards should be 100% programmable. only the key layout is set in stone, and even that can be converted to ANSI/ISO enter and left shift. i know a lot of people like the Ctrl in the caps lock position and they will be able to have that. want a Fn on both sides of the board? you can have that too.
Title: Re: Project: SSK revival
Post by: mkawa on Sun, 29 July 2012, 21:00:14
i'm starting to warm up to the tilde placement on the pure. maybe the scrlock in your layout should turn into a tilde?

also the two keys above it pgup/pgdown

naturally since this will need a custom controller it will be programmable, but let's face it, you can't just release a programmable controller and tell people to "have at it" :P
Title: Re: Project: SSK revival
Post by: hashbaz on Sun, 29 July 2012, 22:15:42
I like the idea of ditching scroll lock for tilde. Don't think I have ever in my life used that key. But as a linux user I use tilde dozens of times a day.

This is all just my perspective of course and it's your design ultimately.  And I suppose with model M key caps it's mostly irrelevant isn't it?  They are all the same profile.
Title: Re: Project: SSK revival
Post by: mkawa on Mon, 30 July 2012, 00:11:54
wcass, i've never seen an XT's barrel plate. do you have some pics you could link or upload?

also, the problem with a think pcb (and the reason why Ms use a membrane) is that the single-key-profile design more or less requires a curved backplate, which is incompatible with most pcb materials. (in particular, cheap ones  :-X)
Title: Re: Project: SSK revival
Post by: wcass on Mon, 30 July 2012, 11:57:45
i'll upload some pictures when i get home.

I measured/calculated the curvature on the XT to be pretty close to 12" radius. The PCB in the XT is .031". that thicknes and thinner will work, but is a curve really nessessary? look at the new Apple keyboards. not having the curve will make the case fab MUCH easier, cheaper, and make the keyboard thinner and easier to transport.
Title: Re: Project: SSK revival
Post by: harrison on Mon, 30 July 2012, 12:55:56
looking forward to seeing some design mock ups of the casing.
Title: Re: Project: SSK revival
Post by: Parak on Mon, 30 July 2012, 13:49:21
As another side note, the singular barrels are all curved as well, so I can see how they wouldn't work all that great with a flat plate. Ideally, a new barrel for flat plates would have to be designed and molded, and here improvements can be made for diy - exact outer 1/2" barrel diameter drill, smaller drill under that for the stabilizing pin, etc. Molding new barrels out of something like uhmwpe is pretty expensive, though. Not to mention that the capacitive feet would still need to be sourced from vintage boards..
Title: Re: Project: SSK revival
Post by: mkawa on Mon, 30 July 2012, 14:03:47
interesting note parak. injection molding is hard, to say the least, and doesn't work very well at small scales. there is 3d printing, but damorgue raised some pretty valid concerns re: surface smoothness. we know that unicomp can provide curved plates and barrel frames, so for this initial SSK project at least, I'd like to stick with them.

what would be really nice actually is if we could look into getting custom membranes made. further, is it possible to print a diode-like device onto a membrane? now _that_ would be cool.
Title: Re: Project: SSK revival
Post by: Parak on Mon, 30 July 2012, 14:17:07
uhmwpe is actually not injection molded, so there are some pretty nice dimensional tolerances in the process. Unfortunately, because it's not injection molded, expect even higher costs :p
Title: Re: Project: SSK revival
Post by: alaricljs on Mon, 30 July 2012, 14:21:36
I thought MS's NKRO board had diodes printed on the membrane...
Title: Re: Project: SSK revival
Post by: fartq on Mon, 30 July 2012, 19:36:31
then the question becomes can _we_ print diodes on a membrane?

as promised, pictures of the barrel plate.

the AT and 122 barrel plates have notches at 30 degrees below horizontal; the XT barrel plate has a hole for a pin centered .4" below the center of the barrel.

to be clear, is the last picture measuring the flat bit of the individual barrel plate? and the other dimension of the ind. barrel plate has the same curve as the underside of the metal barrel insert plate?
Title: Re: Project: SSK revival
Post by: wcass on Mon, 30 July 2012, 22:01:14
to be clear, is the last picture measuring the flat bit of the individual barrel plate? and the other dimension of the ind. barrel plate has the same curve as the underside of the metal barrel insert plate?
the last picture is a side view of an individual barrel. i am still not sure if it was born curved. i think there is a .0005 gap at center curve now, but that might just be from being pressed into a curve for 30 years. when my XTant test plate comes in i will check fit with 84 barrels while the plate is still flat.

for DIY membrane, you can get polyester or mylar sheets from art/drafting supply stores. the M uses .005 for bottom and middle, .003 for top. go to a hobby store for 1/16" wide model masking tape. and instead of silver silk screen, try this:

Title: Re: Project: SSK revival
Post by: fartq on Mon, 30 July 2012, 22:22:33
no need for full DIY membranes unless we have some way to print a semiconductor on :P

BUT, i just realized how we could add components to the membrane circuit: machine more holes in the backplate, place components in holes, connect leads of components onto appropriate points on backside of membrane (which needs to have some kind of makeshift via)

it may be possible to program the mill to make the appropriate holes (just large enough to fit an SMT diode), and vias through membranes are definitely possible, so it may actually be possible to make an NKRO SSK...

Post by: telepete on Wed, 01 August 2012, 14:46:19
This stuff is pretty interesting. I'm glad to hear that you have some plan on how to make changes to the membrane circuit. That would definitely give me some problems.

Hopefully we can make them NKRO or at least 6KRO. (Though going from 6 to N is just a programming nuissance.)

unless my completely insane idea with embedding the diodes in the backplate works (which i highly doubt it will), yes, it will use the unicomp membranes and controller and hence be 2kro.

fyi, we're going to start by getting a precise model of an SSK backplate, and then seeing if there's some easy to integrate a casing into something that's equally compatible with SSK frames

that didn't make any sense. bottom line: one piece backplate and casing. possible? only autocad knows

If you do manage to complete this, please sell it as a kit, so that the rest of us can piece it together.  I would love the opportunity to build an SSK from parts delivered from this venture.

It would remind me of the early PC kits that were sold in the late 1980's.  Buying a kit from Altronics here in Perth then running home to build it up.  Took several weeks to complete but it was done.  Damn I was proud of myself back then.......

my hope is that we can get the case to come in at 200 or less, including custom powdercoating. at current unicomp prices, the rest of the parts are around 100$. i have no idea what will happen to unicomp's parts pricing though if the projects succeeds and the kit becomes remotely popular (personally, i'm just hoping to build 5-10 new units as a proof of concept right now)

one option is to do it without the curve. i am doing some test and can share the below pictures. the barrel frame was cut off of a model M 122 key. it is clipped to a flat clear acrylic backplate. some of the keys have F hammer/spring and others have M hammer/springs. some have 1.5mm neoprene cushion, some have floss in the spring. i'm looking for noise reduction without changing the feel of the key too much. i'll post some video when available. it is very interesting to watch the keys work from the bottom.

I like this layout! It's in-between a Poker and a RACE/Nopoo/etc, I've been looking for a mini keyboard with arrow keys but without a dedicated function row! As others said, replace Sroll Lock with backtick/tilde, you can put rarely used keys in an Fn layer, but backtick/tilde is a frequently used key for lots of folks.

what do you think of this layout? the keys left of the left arrow and up arrow are stepped "caps lock" keys. this should help isolate the arrow block.

If this project moves forward you should redesign the membrane/pcb so it can support 6KRO+, it sucks there are no buckling spring boards not limited to 2KRO.

Title: Re: Project: SSK revival
Post by: mkawa on Sun, 28 October 2012, 08:57:24
so here's the current status: i have a bucket full of parts, all of which combined will make at least one new SSK internal assembly. the trick is that the membranes i have are full-sized. the last remaining task before the first assembly is completed is to reverse engineer the matrix so that when i slice off the extraneous bit of membrane, i can use a circuitwriter or some 24+ga rework wire to patch up the switch matrix. these membranes will interface with the original IBM PCBs and controller.

in terms of casing, my friend and I are starting to look at options for _low pressure_ plastic molding. in particular, acrylic can be formed into an arc without expensive high pressure molds being made (think of it this way: take a sheet of acrylic, heat it, bend it, cool it). i have a guy locally that can do this kind of work in volume, but my bud is in the middle of chemo and can't look at a computer screen half the time without becoming nauseous. obviously the priority is on his health during this difficult time, so i'm mostly mulling over ideas and staring at the assemblies i have until he feels up to making some drawings.

wcass: yes, NOS controllers will be PS/2, but they work quite well using high quality PS2 -> USB adapters. in the worst case, a run of soarer's adapters can be designed and manufactured ezpz. i'd rather do this than try to navigate the space of switch matrices that are available (yes, there is more than one, and only the guys at unicomp know which p/ns match up with which other p/ns)

i'm currently working with several minor details involving variations in plate thickness and bolt pressure and have been sampling imperfect but working assemblies. the only thing this project needs at the moment is a low cost case design. i'm pursuing several design leads at the moment (low pressure acrylic is _not_ one of them unfortunately, as my local source has proven to be unreliable); let me know if you have any ideas and will not flake out.

Title: Re: Project: SSK revival
Post by: mkawa on Wed, 28 November 2012, 16:08:19
sorry, i haven't updated this in a while (or the OP ever, it looks like), but here's what's going on:

1) new case project is mostly stalled. i ave a number of ideas but need more CAD help

2) i have been gathering old and new SSK parts for a number of months. I have a stash of boards that I am refurbishing, and using the opportunity to build a more or less repeatable manufacturing process and specification for  SSKs.

3) as i said, i can build new completely working internal assemblies out of brand new parts from unicomp. unicomp has been working with me on sourcing these, but i am still working out the construction kinks. the original IBM design-for-manufacturing is ingenius, but does not translate as cleanly and uniformly to construction-by-hand as one would like.

4) a crucial part of the manufacturing process is converting 104-key membranes to 84-key membranes. i have two ugly ways to do so and have proofed both methods to build working assemblies. however, i am looking for a more elegant method, and have some more ideas that i'm trying out.

now the important part: how can you help? first, in the coming weeks i will be selling some prototypes. these will be functional, refurbished SSKs that have a weird quirk or two. each board will come in an original IBM SSK case, but will have some combination of new and old internals. the reason i will be doing this is to fund case prototyping, so i will be asking a little over market (although there hasn't been much of a supply of SSKs lately, frankly).

second, i need help in the following areas: CAD work, laser cutting (acrylic or thin alum sheeting), 3d-printing, possibly some 2-axis cnc time. as always, let me know if you can help with this and won't flake.

i will volunteer  to do CAD work. i can do 2D but not 3D. i have used my 2D CAD files to get acrylic cut at Pololu. I also have been playing with KiCAD.

i would like to suggest replacing the bottom sheet of membrane with thin, flexible PCB to mount diodes and Atmel for NKRO. i'm picking some of this up next week: http://www.skycraftsurplus.com/coppercladboard23x17x00080.aspx

the original bottom membrane is .005" so .008 would hardly be noticed. one sheet should do 4 or 5 boards.

as for the diodes, was thinking using a sub-mini array - common cathode by 5 anode (one diode per 5 switches - place out of the way above the F keys). these are $.50 each at Digikey. http://www.diodes.com/datasheets/ds31437.pdf

i have gotten pretty good at DIY etching, but have no experience with sub-mini surface mount. if anyone would like to volunteer to do the surface mount, i would pay for all parts to make two and only ask you to ship one back.

the diodes i would like to use would require reflow (5 or 6 connections in a 1.6mm square package - one on bottom). i would like to use that diode because i would only need to use 17 for an SSK. going with non-array diodes would require 85ish.

wcass: holy crap, awesome find. a couple points to note: that pcb is double sided, so one side should be layered with latex or something to prevent conductive contact with the backplate. second, i'm junk at etching, so yes, definite need to collaborate on this.

If there's only 1 bottom pad and the rest are leads it shouldn't be too much of a pain (for prototyping) to punch a hole through the PCB and solder it from the bottom.  This is even more true on such a thin PCB :)

Yea, how does Unicomp feel about this? It seemed like they were interested in doing a mini-run of these before. They did a big interest check for it where we were supposed to send them tickets.

Also, will these have at least 6kro? I apologized if that was posted before but didn't see it in the OP.

I don't know about Unicomp's position on this project, but I know that Unicomp is not interested in Tenkeyless Keyboard yet. I have asked what they have planned for TKL keyboard. The response I got was they do not make TKL keyboard in near future. I don't know how long the "near future" refers to.
Anyhow, I guess it is more than 2013....
Title: Re: Project: SSK revival
Post by: wcass on Wed, 05 December 2012, 21:11:18
i picked a different diode that should be much easier to solder and am hard at work designing a prototype. the new diode array is an 8x - equivalent to 8 discrete diodes but in a single SOIC16 package. the prototype will use 11 of these.

Is this something that Unicomp will license from you to put in mass production?
i don't think that what i am doing here is anything new. using a diode to isolate a switch is fair use. but it does make it possible to give membrane keyboards full NKRO with the right controller. i think the reason this has not been done before is strictly cost. in volume, a silk screened membrane probably costs < $2; what i am doing will likely cost > $20 per keyboard.

Here is my current thinking on the keycaps.  (Alternative uses for the Caps Lock key still brewing.)

Also, I've got the cut-lines worked out.  I am thinking about a case/platform, how to accommodate the double-fold needed, and where to put the LEDs.  Mr. mkawa has provided a contact at Unicomp, but I am not quite ready to discuss/order component parts.

Maybe it's a bit early to ask about smaller details, but:
Is there a notch for a sticker designated?

Are there plans to do a replica of the small ibm badge/sticker (top left corner)?

Is Unicomp able to produce the ssk specific keycaps with the additional symbols (maybe even iso)?

i created replica/replacement labels for real IBM keyboards, but there is a legal issue with putting an IBM label on a keyboard that IBM didn't make.

we could design unique labels for this. i would definitely go for a birth certificate done in the style of the IBM back label.

and i can confirm that Unicomp does make SSK specific keycaps - even in iso!

Edit: i ordered these 3 months ago. i wish i had more time to work on my keyboard projects!

mkawa, i think it would be a good idea to have a "birth certificate" go out with the keyboard kit. you will need to decide what info you want to put on it - batch number and date are obvious, but you could also customize each logo with a username. this is a mock-up of what i have planned for the XTant. the creature is called a Tuatara. google it to see why it is the perfect mascot for the XTant.

quick update: boost is getting the first prototype board (in a classic SSK case). all its internals are new and it has been constructed in my newest assembly jig (really just a panavise with a particularly appropriate set of modules :P) and bolted to my best-effort torque spec so far. he has been instructed to beat on this board to see if it will break under normal usage.

a small cabal is working with me on case designs. part of this work is going to necessarily involve me learning to cad appropriately, so i suspect it will be a long process ;)

i feel pretty confident about my newest assembly jig and torque spec, but still managed to build two non-working assemblies this past week. i think the issue is the vintage membranes I used, but only full teardowns and inspections will tell. more likely, i will just build up the assemblies using brand new membranes (as in boost's proto#1). anyways, slow but steady progress huzzah

eta: also, iso fans, i believe iso will be possible using the exact same techniques but just changing the membrane, keyset and controller part numbers. i don't see it being an issue.

i have two or three assemblies unspoken for at the moment and more than that many people interested. i have some ancillaries to take care of before the boards are complete, so i will be taking care of those and getting to the point where i have a few boards ready over the next N days. at that point, i will post a google form for those interested and pick (most likely at random, but with a bias towards those who can and will use the board as their daily driver for at least a few months) a couple of recipients. tentative pricing is 200$ + CONUS shipping. the board will include a usb cable and a completely informal warranty in that i will want the board back if anything goes wrong (with a full refund if i can't repair it for some reason, naturally).

this will be the first round of betatesting, and is only meant to QA my construction method, specs and current makeshift jig. there will be future rounds as more of the project is finalized (and a few one-offs with weird parts that i've recovered from all the SSKs i've pulled apart at this point).

i did in fact just undertorque boost's board, and it may have gotten even looser with usage on top of that. the offensive key works again, and the board generally feels "right" now. it's going to go back out to him tomorrow and then he's been instructed to smash it again to see if i need to go to even more extreme measures to keep the assemblies in spec.

the other two assemblies i have ready will go up this weekend.

the little tabs on the bottom are meant to fasten onto a solid, lasercut bottom plate made out of a stiffer denser material (alu, acrylic, etc.). similar bits could be stuck into the back and sides to enclose the case.

there's also a top designed, but it's optional. you can use the case without it if you want.

most likely the bottom and will be a piece of sheet metal bent in front and back. the sides will be all plastic. and will attach to the bottom/front/back via fasteners. the geometry allows any number of different material combinations though.

Well, for the lower full case mkawa posted... if you're a really good machinist, you can arguably do it with a vertical mill (provided you're also up for some welding.)
But this here (http://littlemachineshop.com/products/product_view.php?ProductID=3829) is your typical starting point roughly for a CNC vertical mill. Tormach's got reasonable accuracy - if you want to go production grade accuracy, micro-machining or larger table the price goes up very quickly. How much? A Bridgeport Acu-Rite in used shape will cost you $18K+ - and that's on the small side. A beaten up Mori Seiki vertical SV-50 with 31.5" X-axis, basic controls (no Fanuc set), no vises, and 10K RPM 30HP will set you back at least $62,000 (http://www.ebay.com/itm/1999-MORI-SEIKI-SV-50-40-CNC-Mill-Vertical-Machining-Center-/151000526156?hash=item2328552d4c). (Plus the concrete work to support a 9 ton machine.)

You don't want to know what a 58" traversal three-axis costs. Forget a five-axis Cincinnati.

But if you want to get started with a mill? You can toss 'high accuracy' at the start. But still figure on spending at least $5K - besides the mill, you'll also need a lot of tools and equipment. And that stuff is not cheap.

the milling they're talking about is really simple, more of a drill press job. the plastic barrel carrying frames come in with plastic rivets sticking out of the back instead of holes for bolts. the challenge is drilling those rivets out quickly and efficiently so you can do batches of like 20 at a time. rknize has a manual mill and a jig that he uses to do it but is short on time (lead time in the half dozens of months ;)). he currently has about 10 or 20 frames that he's working his way through. people were volunteering to go over to his workshop and drill the rest out with his jig for the greater good ;)

Hmm... the barrel frames do present a problem and then some. They're poorly suited to my drill press to put it mildly. (Trust me: do NOT attempt bolt modding with a big drill press unless you have a curved shoe AND vises for it. I don't have the shoe.) This is kind of why I'd really love Unicomp to just change to a bolted through die. Alas. Optimally would want to use a CNC drill press (http://www.youtube.com/watch?v=LdHTywvZQZ8) to do the job, but given the variances in the plates from die wear, it'd probably ruin more than it actually produced. :(

BTW, for the bolts, I checked my notes. You want to use Loctite 290 "Green", not 242. "Blue" 242 has mediocre vibration tolerance and "Red" 271 is for absolute permanence. 290 isn't quite as easy to find in stores and yes, is the about same green you see on many bolts in IBM parts. (Also don't confuse with their superglue, which has a green label.)
Loctite 290 Green - $4.99 at JEGS (http://www.jegs.com/i/Loctite/198/37423/10002/-1?CAWELAID=1710844781&catargetid=1716046196&cadevice=c&&cagpspn=pla&gclid=CPu1vdSSmbgCFQWk4AodvDUAuw)
Great stuff. I recommend keeping a bottle around for projects regardless.
Title: Re: Project: SSK revival

i don't want loctite at all, as it ruins torque measurements on the bolts. i may or may not have mentioned that earlier. i will be transitioning to either jamb nuts or lock washers or both.

you're still very confused, unfortunately. the barrel plates are molded ABS and pretty precisely uniform, actually. a small 2-axis mill could make short work of the matter, but i don't have the money for that tooling at the moment, as i'm currently debugging our very expensive FFM printer.
Title: Re: Project: SSK revival
Post by: mkawa on Fri, 05 July 2013, 17:53:49
actually i should post this somewhere as i'm not sure i have it all out there anywhere but my head. here's the construction process for an ssk revival keyboard:

INTERNALS ASSEMBLY

1) drill out the plastic rivets from a new barrel plate, as in any other bolt mod (well, with a new barrel plate). currently, this is being done with rknize's manual mill, because he was naive enough to offer a while ago, muahahahaha.

2) modify a new IBM-matrix model M 104 membrane by slicing off the tenkey. bridge the cut traces as appropriate using a combination of small gauge magnet wire, and conductive copper tape. some of the details of this are TBA. i've used a variety of bridging materials and haven't been entirely happy with any of them. these seem to have the most promise out of those that remain. the beta boards actually just folded the excess membrane over, which works fine electrically and mechanically (for the most part... jury's still out on that actually, it may have contributed to some of the problems that were partly due to warpage of the backplates) but is inelegant, and may not work so well with the new case design.

3) sandwich 2 pcs new stamped steel backplate, ABS barrel plate, and M membrane, secure with 2mm-longer-than-normal-bolt mod screws (which iirc are M3, but i have hundreds at home and will correct this when i get there). secure with lock washers, 4mm nuts. torque to 2inlbs. (again, i may have to correct this when i get home).

4) attach to new SSK controller board. wire ground to somewhere sufficiently large and conductive.

CASE ASSEMBLY -- MOSTLY TBA

1) print 2 ABS assembly-side-pieces. the reason why we need these is because we need to want to form-fit the curved assembly at the edges. for support reasons. now that our printing costs are significantly lower, the sketches you saw will probably be widened, actually -- the original design attempted to minimize volume due to printing cost.

2) print a pcb retainer. because we can.

3) fasten both to cut and press bent sheet metal frame that will serve as keyboard outer. we're probably looking at thin stainless, because it's cool, and because the assembly mostly supports itself if you give it a nice but minimal platform.

i don't want loctite at all, as it ruins torque measurements on the bolts. i may or may not have mentioned that earlier. i will be transitioning to either jamb nuts or lock washers or both.

I've done scale assembly engineering for sensitive parts with torque-limited drivers - specifically motherboards where overtorque cracked them and backout fried them due to short. Hence why I specified 290 wicking - Loctite does not have an impact on torque unless you're using the wrong compound. Wicking compounds are less susceptible to application error generally. The whole point of Loctite is to ensure torque is maintained and does not change over time. Really should be using Loctite 222MS "Purple" but Grainger's website is being broken AGAIN - prevail on 222MS is 30in-lbs, which is pretty much free-hand tight. 290 will not affect torque, but it's very much "GFL getting it apart ever again." And 222MS requires you apply it correctly. Blue is entirely inappropriate here as it expands quite a bit and isolated to the application area. (Also 222MS used to cost a lot more than 290.)
Loctite is specifically indicated for torque sensitive, tight tolerance parts all the time. Loose fitting OTS M3 fasteners (anything over 0.005 is loose) should be using Loctite. I recommend looking around Practical Machinist sometime - it's a frequent topic of discussion. The TL;DR is that most problems with Loctite and other thread lockers are summarized as 'using the wrong one for the job.'

No, I've worked on M's - a lot of M's. I see two problems. One, if you run the RPMs too high or move too quickly you produce heat distortion and damage. Two, by my calipers I'm finding variances of 0.3mm to 0.7mm between two same-year (91) back plates and molds. And no, not Greenock. I'd presume these are somewhere around the same, which obviously is moot if you go oversize by +1mm.
And I've been advised the fastest way would definitely be drill press with tilting table using a horizontal clamp rather than a mill. Don't look at me - this is from someone who's been turning parts for over four decades. Pretty sure someone who can get better than 0.001 on full manual three-axis and do 144 holes in an hour knows what they're talking about. Plus, looking around, looks like it's also a very cheap solution in terms of equipment - can be done under a hundred bucks including the drill press!

for your approval.

print the PDF on 11x17 at 100%, lay your membrane on top and see if i need to adjust anything. if anything does need to be moved, mark up the JPG in paint using red or blue and repost. the extra bit on the top membrane is so that the tail will fit either 8 pin or 12 pin FFC connectors - depending on where you trim it.

i don't like what had to be done on the right side of the bottom membrane. just a thought - you might consider a custom controller; we could change the matrix so the paths are more efficient and add a Winkey option. the controller would also be a drop in programmable replacement for most older M's.

if i can figure out how to massage my macro setup into a copy stand in the next hour two i'll just send you tiffs. otherwise, mail it is!

rootwyrm: if you would like to help, you are free to contact unicomp, order 20 plastic frames, have them drilled out however you'd like, and then send them to me. if you'd like to go one further and construct the entire internal assembly yourself, that would be even better. thanks.

added the odd cut-outs at the top of the membranes and part numbers to match those on the stock sheets.

i made the rivet holes round so that they can be easily punched out with a cheap die. should i make them match the shapes of the originals?
Title: Re: Project: SSK revival
Post by: mkawa on Thu, 18 July 2013, 09:15:45
no, round is perfect. hell, i'll probably just shove the screws directly through them after poking them by hand with an awl. the weird shapes were due to tooling that unicomp had long ago but no longer use.

Post by: rknize on Thu, 18 July 2013, 13:56:23
Well...if you look really carefully at a barrel plate, there are oval shoulders at the base of every peg.  I believe this provides a fixed offset between the back plate and the barrel plate.  Doesn't the membrane need to match the shape of these?
Title: Re: Project: SSK revival
Post by: mkawa on Thu, 18 July 2013, 16:00:51
i believe those are horizontal positioners and tehy don't, as far as i know, provide an offset because they go through the ellipses in the membrane. the large sills that run horizontally across the barrel plates provide the fixed offset. the holes just need to be large enough to fit those shoulders (ie, the holes should not be 2mm diameter, they actually need to be 5mm diameter, which i believe wcass put in his pdf, as he just went for the closest circle to the weird ellipses and partial arcs that are on the membrane). that said, i think all of these weird features on the membranes are positioning functionality for the tooling to exploit to lower the x-y tolerance on barrel to membrane, as ideally each hammer should be exactly centered above each pad. that said, the actual membrane tolerances are huge, and i don't have a large dedicated die that can press out these shapes. i can do 5mm circles though. that's pretty easy (and yes, it's me smashing a 5mm awl through. THERE I SAID IT

i use this to make my holes:
http://www.harborfreight.com/9-piece-hollow-punch-set-3838.html

the holes are just for alignment. if you look at the membranes, you will see that the smallest hole on the membrane (about 2.8mm and round) is just top-left of the quote key - this is the membrane position anchor.  other holes on this row allow some horizontal position play, but little vertical play. holes on other rows need more vertical play due to the curved back plate; the greater the distance to the anchor row - the greater the allowed vertical play.


Title: Re: Project: SSK revival
Post by: mkawa on Fri, 19 July 2013, 09:02:38
i should be able to print out a punch set even for the weird shapes. can you just dot the center of each hole? i can go off a production FCB to get the exact weird hole to punch for each bit

What's going on with this project kawa? 
Title: Re: Project: SSK revival
Post by: mkawa on Fri, 09 August 2013, 22:56:56
it's mostly waiting for me to get back to it. acetrak is finishing up the sheet metal drawings. the break points are there but the various cutouts need to be drawn in still. the pcb mount also needs to be put into the assembly file, and all the plastic pieces need to be revised to be bigger and thicker for easier printing

on the internal assembly side, i have all the parts i need and a new construction rig to try making a folded membrane 1.5-2mm thick backplated assembly that should hopefully not warp or really flex at all. the one issue with this is that the plates need to be bonded together so that they don't just flex out of alignment with each other (since the bolt holes have fairly large tolerances). the boring solution to this is is a little bit of jb weld or other metal adhesive. the fun solution to this is capacitive discharge welding.

the final bit is the membranes. wcass and i want to try this short run FCB vendor, but their order requirements etc. etc. are too much for me to deal with right now. i have a living room full of stuff for the geekhackers store, an active 3d printer that breaks a part every 75 build hours (and it's up to 150-200 or so :D) and i have some pretty serious real life stuff that is incredibly urgent.

also i think i have to go to keycon or something.

will this work, or do you want a smaller dot?
Title: Re: Project: SSK revival
Post by: mkawa on Sun, 11 August 2013, 15:11:08
those dots are perfecto. only one thing i can see offhand: that dotted line on the FCB connector for the 386 layer, just get rid of everything to the left of the dotted line and make the dotted line a solid line. i'm not entirely sure why that bit is there, honestly.

also, i'm guessing this place is not going to cut the outlines for us, so could you make the FCB outline maybe 3-5 pix wide?
Title: Re: Project: SSK revival
Post by: wcass on Sun, 11 August 2013, 18:13:07
3-5 pixels at what resolution? the border line in the original is 5mil (3 pixels at 600 dpi). the new border is 10 mil (3 pixels at 300 dpi). if you would like that changed to any value, that is a 2 minute fix. just give me a value.

flap is removed in this version, but my understanding was that this project would be using vintage 101key controllers. some of those controllers will have 3 FFC connectors (16-8-4) but some might only have 2 connectors (16-12). the extra bit is "padding" so that the membrane would fit proper in a 12 position FFC or could be cut back to the dotted line to fit an 8 position FFC.

also, 3mil top sheet fits too loose in those FFC connectors (connector spec calls for 5-15mil). older membranes fold a flap to bring the contact area up to 6mil. newer membranes use stickers to bring it to about 9mil.

10 mil at 600 dpi would be perfect.

the project is using new old stock 84 key controllers (and old old stock, i literally can't telll the difference and they're all in the same box). all of them have the shorter connectors, so i've been doing a lot of cutting.

hmm.. if we were doing high speed mass production, i would say go with the flap, but my experience has been that even with fcbs at the specced thickness, there's a thin layer of oxidization that requires a bunch of fidgeting with the connectors. i'd rather purpose-build an army of small pieces of spudging out of another material that is stiffer to help induce electrical contact than screw with folding over flaps.

thicker packaging tape or label stock would probably work nicely. place it before cutting the membrane outline.

Post by: mkawa on Wed, 02 October 2013, 20:30:31
it is really just a matter of time. the designs don't really need that much work, and the membrane situation is under control enough for a first run, but i would need a whole bunch of time for construction and the budget to have the sheet metal cut and bent AND the printer needs to be up, all at the same time. quite a few moving parts, unfortunately. on the upside, the hardest work has been done for the most part. it's just a situation where the ROI is hugely negative (this was always a labor of love for all involved) and geeckers needs a revenue stream right now, so i'm focusing on meeting people's immediate and small-scale needs first.

i'd prefer to make the first run of cases because they're a bit complicated. there's a plastic and metal component, and our plan is to lasercut stainless, which requires an amount of power that would be unattainable if it weren't for the_beast's laser cutting contact.

if everyone involved agrees, after the first run the board design will be made available under some variant of the ggppll. also, trading up to a revival board, if they come out like i want them to, won't be unheard of. the plates are going to be thicker than the thickest plates i've ever pulled out of an ssk, and the bottom case will be stainless instead of the break-prone plastic that the OEM units use.

To be honest, I am not big on TKLs, but I would consider going for a new style SSK. I currently have 4 keyboards on my desk (5 if you count the built in keyboard for the laptop I have docked), and can see the benefit of not having everything be fullsized. As long as my main keyboard is fullsized, I would still be happy.

Also, I am a fan of metal. The stainless steel bottom sounds really intriguing. As long as I have the funds by the time things roll around, I would definitely want to get one.

I got to try one out while staying at mkawa's apartment. I've gotta say that if I didn't have an SSK already, I'd be all over this. Hell, I *HAVE* an SSK and I'm still really interested in this. It doesn't feel *exactly* as springy as my SSK does but overall, it's so good that I was impressed. The new plate, the assembly of it, and how clean the folded Model M membrane looks all look great to me. Plus I thought the way mkawa had it bolt modded was very nice. The case felt..."tighter" or better assembled than my SSK (no offense to dorkvader).

Kickstart it? You have prototypes, so that's enough to get going. Have interested people make donations, and if they want to get in on the next batch of testing, have a higher end donation range that would be enough to fully fund the build of a keyboard for them.

1) we've attempted to work with kickstarter before and they do not like us.

2) kickstarter takes 10% of proceeds. we have community funding here and on the soon-to-be-launched geekhackers store

3) i don't have time. really, very seriously, i don't have time to build a single board right now. even if i built another jig up with new parts and have the money to get the sheet metal cut, i would not have time to make a single unit.

sorry, but patience is the only answer here.

I wasn't necessarily meaning kickerstarter itself, but the basic general premise of crowd funding.

As far as point number 3, that goes without saying. Everyone knows that you've been crazy busy, plus not even home much. I think we were mostly just spitballing ideas to try and come up with a solution for the money part, since the only solution for the time part is to wait.
