Title: [IC] JD40 40% boards: metal, plastic, and a celebration of smallfry's life
Post by: mkawa on Thu, 08 May 2014, 13:00:47
Folks,

I've been talking to a number of people who want to come together and celebrate smallfry's life. Yesterday, we bounced the idea of a 110 red on red keyset that harkens to one of his favorite boards. We've been talking about the economics of it, and what we've come up with instead is a group buy of JD40 40% boards. I'll let jdcarpe talk about how he and smallfry worked together on the 40% board idea, but the basic idea for the GB will be pretty simple from a participant's point of view.

We are going to build kits to make JD40 boards. The layout will not be customizable. It will be a basic winkeyless layout with possible one small change for a key that acknowledges and celebrates nathan's profound influence on the board, both the keyboard and the forum.

each kit will come with:

1x titanium switch plate
1x PCB
2x acrylic spacers
1x aluminum bottom plate
1x bumpon kit
1x red on red keyset designed specifically for this board


1x titanium switch plate
1x titanium bottom plate
1x sorbothane spacer gasket
1x PCB
1x bumpon kit
1x fastener set

the smaller size of the keyset will keep keyset costs reasonable. the titanium will be polymer coated for durability, and the aluminum will be either protected or colored via anodization or powder.

any and all money made on this GB over the cost of materials and labor will go towards the nathaniel j walter foundation. assembly services will be available, details TBD.

we miss you nathan. :(

update: regardless of what goes under the titanium switch plate, the switch plate will NOT have switch-opening notches. If you want switch-opening notches: head here http://geekhack.org/index.php?topic=58073.msg1333490#msg1333490 to purchase. limited quantity available. Note that proceeds from the notched switch plates will not go to the NJW foundation.

The layout will not be customizable.

Am I correct in interpreting this as the physical layout not being customizable but the controller (Teensy?) still being fully programmable?  For that matter, do we need to supply our own controller?

yes, and good question. jd has dealt with pjrc before from the previous GB. since fulfillment will probably just be JD and I, it should be easy to include a teensy with the kit.

as for how many will be made, we have to determine the multiples of units that can be yielded from each piece of material, but we generally want to include everyone who wants one.

Making the caps available on the side would allow us who already have a JD40 to participate, which would be much appreciated. It shouldn't drastically complicate things since caps will already have to be a separate order from PCB's/plates…

Just wanted to add a little note here. SmallFry didn't really design the 40% keyboard with me, but he was very supportive of my design in our personal conversations. It was the first new design of mine to be realized after we lost SmallFry, so I decided I should name the new keyboard after him. Regack was kind enough to include the dedication to SmallFry on the new revision PCBs, but these older revision PCBs won't have that.


We should probably include a Teensy and header pins with each kit, as well as diodes and a few other components that will be needed to build these.

one of the major problems is that unless there are a lot of takers, we would like to limit the cap set to 40% for pricing reasons

He's asking if the 40% keyset can be made available to people separate from the keyboard kit. Because there are a few of these keyboards already in the wild now.

Is there any sort of a rough ballpark idea on price for these?  I would love to try out a 40%.  It will be one hell of a transition from full sized.

I know you sell JD40 kits for 200$, now this even has a titanium plate and a keyset so I suppose the price will be quite high? I am interested in one but I don't know how much I would pay for this :-X

Well, that is with switches, and assembly labor. And the fact that I order the components in small batches keeps the price high for me.

In some volume order, the PCBs will be cheaper, plates will be cheaper (well, the Ti will be more expensive, but you get what I mean), etc.

With that amount of switches they don't make a big impact though :))
Well as I said it depends on the price for me. I like the 40% form factor, it's just cute :3
On the other side I don't know if I could use a 40% as my main keyboard, which is what held me off of buying one.

we're looking at ti switch plates only. a ton of 40%s can fit on one of these sheets. further, i have been working with my cutter on reducing cutting cost significantly.

Potentially in. I've been waiting on the development of JD's 40% design and for a kit to become available. What's the layout going to be, exactly? I had some caps already in mind for a 40% but if it's winkeyless they will probably not fit...

EDIT: I've ordered these with the hope I'd be able to use them on a JD40/SmallFry board, at some point.

(http://deskthority.net/w/images/b/b7/HONEY_FORTY.png)

Also, if this is the first version of the PCB, what's it lacking vs. the revised version that's still in the works? Sorry if this information is already out there somewhere and I've missed it.

You might get a larger overall saturation if you offered both: aluminum to the folks whose wallet hasn't recovered from its last hack, and Ti for those in a position to go all the way.

if we do two materials, the labor cost of cutting is going to double, which will negate any potential cost savings. volume and uniformity is essential to cost cutting

I would prefer Titanium personally.

titanium would be lighter because the aluminum sheet would need to be thicker to get the same rigidity

cost depends on how we end up building this thing and how many get made.

The Poker Mk1 was a cheap SOB - which they corrected (somewhat) on the Pure.  That being said, Vortex product in general isn't exactly stellar quality.  Even the Cherry G80-11900 is more stable for a PCB mounted application and it is much larger.  Unfortunately PCB mount style has started dying out  and it's a shame because they do give a very unique feel and sound.

standard pcb thickness is 1.6mm, and the material is always some variant of FR4/G10. the only way to make a pcb more rigid is to increase the tie points to something more rigid. the cherry pcb mount boards basically have a pcb flush with a large plastic plate behind it with a whole bunch of tie points. metal plates basically seal the deal. i had two pokers that i plated with aluminum plates up top and 12mm plates behind, and that was basically the only way i could get the poker pcb to stop flexing.

I'm using a Pure now with stock ABS and I'm trying to come up with an onomatopoeia for the sound and the best i can do is that it gives a tak tak tak tak sound as I bottom out repeatedly while pressing B.

That's an "a" as in how you would pronounce "arh" in "ark", not "ay" as in "tray"

you'll need to find a buyer for the bottom plate if you don't want it. we will be cutting these in matched pairs.

note: check out the currently running buy in artisan services if you only want a top plate. we are about to cut a single sheet with any design you can fit on the sheet, nested for cost savings. that buy is also utilizing a cutter that has a press bender with titanium friendly tooling if you want a full bent-flange 40% one-piece case.

What I read so far is quite amazing, dedicating a unique keyboard to Smallfry here.

So no one has envisioned the casing yet on what a 40% keyboard would look like?  If anyone will produce an illustration you guys need to etch or carve his name into the casing so everyone knows what it is.

Nothing more decent than seeing Smallfry's name emblazoned upon this keyboard, much like LZ-GH's is on their keyboard casings.  People need to see his name either on the top plate were the keys are situated or on the sides/back plate.

That way when someone wants to BUY a Smallfry everyone here know's what they mean (besides if it worked for Karl Benz naming his cars after his deceased daughter then it will work for Nathan) :thumb: .

JD has drawings for acrylic spacer layers, but i'm leaning toward spacers on the fasteners. i'm kind of tired of layered acrylic, even if they're just spacers, and spacers on the fasteners allows for building an angle into the keyboard itself.

further, the spacers could be made out of cut to length polyelastomers: sorbothane carries bushings in various lengths as stock items, and polyurethane extrusions are inexpensive as well. energy absorbing PU springs instead of rigid polycarbonate, and titanium instead of aluminum would make for the deadened feeling of a large heavy keyboard in a very tiny and light one.

yah, so JD's picture is fasteners with some sort of spacing coupler or shaft that just surrounds the fastener and keeps the two plates at a given distance from each other.

the other option is to fully enclose the space between the plates with layers of acrylic.

the former option is cheaper and allows the front and back heights to be non-equal. acrylic is often used as a light guide though, since light tends to diffuse through the material. if you had leds on the underside of the board in JD's picture, you'd see a bunch of point light sources in the reflection, but not get the diffused glow that's in cptbadass' picture

I think going for the acrylic in CPTBadAss and using feet to change the height is the best option.

another point on the acrylic is that it's going to obscure the bottom plate. in that case we might as well make the bottom plate thicker aluminum.

If this ends up looking like a 40% GON I am certainly happy with that as a result :P

On the other hand, I think there's something to be said for the home-built look and keeping the price down.

I'm good for either.

Any update on the layout yet?

I'm down for this, TI to the max. I'd like the option to buy spacers and acrylic because I'd like to be able to do both depending on mood and such.

I don't remember seeing it, but would the JD40 plate allow switch housing removal? If yes then this would be a cool board to have around to swap switches or springs for experimenting since it wouldn't be as many switches as a 60-80% board to swap out.

I think mkawa wants to do them as kits, really. But the plate is the case here, so I don't really know what you mean by "DIY a case."

My suggestion would be to make the spacers as default, and have the acrylic spacer layer available for anyone who wants to buy it as an add-on.

And yes, my drawings have the correct openings. :)

we're only going to be able to go with one of the two options. full Ti without acrylic or Ti top, alu bottom with full acrylic. the way we're going to cut the Ti involves stacking Ti sheets and using a multi-headed waterjet. it's a bit of a dance to cut, but the radio edit is that there has to be a high degree of uniformity in our cuts.

Yes, you can always add the acrylic spacer layer at a later time.

BTW, for the thru-hole PCB this is based on, you would need 12mm of separation between the plates, minimum, for the Teensy's USB connector. So normally, that would mean two 6mm spacer layers.

we're really flying by the seat of our pants here. we definitely don't know how much the kit is going to cost, as we haven't even decided what will be in the kit.

again, flying by the seat of my pants here, i THINK that the notchless plates will cost about 30$ less than the notched plates. the price of materials doesn't change, so it's all in the cutting costs. the argon shielded incredibly precise lasercut that this first piece is getting is expensive, but my guy has been pretty cool about costs so far. for the big runs, the less precise waterjet is going to be a lot cheaper, but again, the material is a fixed and non-trivial cost.

my suggestion, the NJW foundation notwithstanding, is to buy a notchless plate now if you even think you might want one. remember, i'm not going to cut notched titanium plates again, ever. period. nada.

my machine shop can't give me tolerances as tight as the laser can. the material is too thin for the mill. this is sheet metal work.

i have a carbide countersink bit, but with the material being so thin, i don't want to potentially ruin your plate trying to get a countersink in there. further, most countersunk machine screws have a head size taller than 2mm

sorbothane feet can tend to be sticky in lower duros, and we're already going to get the dampening of sorbo from the gasket between plates.

the nice thing about bumpons, assuming you can find one that you like the angle and feel of, is that they're really cheap. if they come off, you just put a new set on. they're also super adjustable

yah, ok, i've thought about this, and to keep prices low, we're just going to go with bumpons. i will query the sorbo people and see if they can offer bumpons in quantity with some kind of coating to make them non-sticky and to provide them with top notch PSA that won't come off unless you really abuse them, but if we machine the feet, they're going to cost as much as the rest of the parts combined.

TODOs on this: keyset pricing and bottom plate: what material? Ti means only one source of material, but aluminum may be slightly more cost effective. my worry with aluminum though is that it has to be finished, which is extra cost. thin stainless is an option, but if you go too thick, you get flexing, and if you go too thick, it weighs a ton and cutting fees will make it just as expensive as the Ti.

basically, we can cut 30pcs of plates out of a single sheet of Ti, which makes the marginal cost on materials pretty low. the cut on stainless and Ti is going to be the most expensive part of the equation.

if we have a price estimate for both Al and Ti, it'll be easier to make a decision for the overall build, as well as the prices for other parts (PCB, switches?, LEDs?). I'm all for Ti since i got the notched place, but still, an estimate would be nice.

at scale, polished titanium sheets are 20$ per 40% sheet. we may have trouble hitting scale only cutting the tops.  the other project consuming this material is up in the air at the moment.

anyway, the cut is all time spent under the jet, so it costs about the same amount to cut the alu as the ti. for alu we'd probably do about 3-4mm thick, but it would have to be polished, cut then ano'd OR all the plates would have to be sent for powdering. raw alu isn't going to work, and you can't ano unpolished sheet.

actually, it might cost a bit more to cut the alu because we may not be able to stack it due to the thickness. anyway, think of the ti bottom as possibly saving 15 ish dollars per kit.

sorry, that should have said "think of the alu bottom as saving 15-ish dollars per kit" and that's a maximum. it could totally end up breaking even

it also increases complexity of obtaining material and so on and so forth

but yah, ti is about as resistant to corrosion as stainless steel, and nearly as strong (alloyed ti is much stronger) but weighs as much or less than alu

i should note that normally, working with titanium is a HUGE pain, as is sourcing it et&c. however, i've developed a network of shops and suppliers that make this pretty much moot at this point.

For the same volume of rae material Tiweighs more than aluminium.  On parts where the shape and mass of the material can be manipulated Ti comes out lighter in a lot of cases due to its different physical properties.

I've definitely been interested in 40% for a long time. However right now I'm definitely worried about price. Is there any estimate on how much all of this would cost? Also how much would keyboard assembly cost, will there be options for switches to be sold with the set?

I apologize for all the questions but this is the first GB I've been interested and willing to participate in.

I have wanted to address this for some time now, but never got around to it until now.

This is definitely not a kit for the absolute beginner. I would classify it as an intermediate build. There are a couple quirks to the assembly that could prove frustrating for someone without the proper tools or skills to deal with them. Not to say that it wouldn't be possible for a beginner, but it may be a challenge.

the only thing i have a 100% solid price on is the material cost and tooling and per piece cost of the sorbothane gasket. i can tell you that at 50pcs, we're looking at a little over 2000$ for tooling and materials so far. i'm going to need to make the first payment on this next week, so i am actively trying to work out a total cost as well as come up with margin for donation to the NJW foundation so that we can officially start the group buy and start taking orders. i should be able to get a number on the cuts on tuesday from my waterjet guy, and JD and I need to powow on the PCB cost. that should be basically the entire picture, as long as we go with bumpons, so cross fingers, the GB will start next week.

just a quick note: i've been trying really hard to make this as affordable as possible while still being kind of a special cool kit with stuff we've never done before. i appreciate everyone's patience as we put everything together.

second note: ironically, i think we may have to skip the keycap set, as set costs at projected quantity are pretty darned high; probably the largest cost we'd encounter.

Can you clarify as to what challenges there are that may pose frustrating for a beginner?

1. The silkscreen is only on the front of the PCB, but the diodes, Teensy, and USB connector need to be soldered onto the back side of the PCB.

2. The solder pads for the diodes are somewhat small, and need care and extra time with the tip of your iron to ensure good heat transfer, thereby ensuring a solid solder joint.

3. The Teensy needs to be soldered flush with the PCB. Spacers must be removed from the pins before soldering the Teensy on, as with the Phantom.

4. The USB connector on the top edge of the PCB needs to be connected electrically to the connector on the Teensy. This means soldering a jumper cable/wires from the USB connector to pads on the PCB, similar to how it's done on the ErgoDox.

I would probably classify the difficulty of assembly as being very similar to that of the ErgoDox.

why don't we just silkscreen and pad the back of the pcb, add a couple mm of thickness to the gasket and build in a proper ground plane and vcc rail?

Those would delay the project as a whole, and while not yet on a timeline GBs do tend to run over time and over budget.

But of those, I think the VCC rail offers the greatest frustration-reducing ROI, as dismantling a USB cable for the ergodox is less than satisfying.

The silkscreen thing just means you have to flip back and forth a bunch to verify which goes where but once you remember "all the diodes go to the left" then you don't really have to remember until your next soldering session. Of course, it would hardly (I assume?) add to the cost of production of new boards, and of the current revision, there aren't any already produced, right? So that would be the simplest improvement.

Having removed the spacer from both my phantom project and the ergodox as well, I'd personally say that a thinner board is a more beautiful board. Don't worry about padding just to let the Teensy stand all the way up; I didn't on either of the first two things I ever soldered together, and it wasn't that hard.

Interested in a 40% PCB and the possibility of an Aluminum plate.(?)

Just getting into Mechanicals and $200 is a bit steep for me with trying to save for tuition. (although it is for a good cause) I'm looking for a project board to DIY, and a 40% seems like 40% of the work of a full TKL or something. :) (and just a fun form-factor to play with)

I'll pass as I really don't want or need a 40%.

But you have my support. And if this is successful and you do a bigger (at least TKL) version, I'll probably be supporting that.

the problem with TKLs is that they're a little too big for our material size. yield is low, so each keyboard is going to be pretty darn expensive. there's nothing else really stopping a TKL version though.

60% will probably be next.

i'm going to try to get a number out of my cutter tomorrow. if i can't, i'm going to price the product on geekhackers.org, put it up and you will be able to start ordering by tomorrow EOD. if i do manage to talk to him and it comes up high (worst case), then i might have to do a bit of thinking on how to lower costs. i suspect i will be able to talk to him and he'll give me a quote in the ballpark i've been predicting, in which case, you will be able to start ordering as soon as i price the product, give it a description and some pictures and get it up on geekhackers.org

re: LEDs. no, the current PCB does not support LEDs. that does not rule out the possibility of a board with the same layout and form factor with LEDs in the future, however.

as for parts you will need, expect to buy switches, diodes, potentially a small number of resistors and a mini usb female jack, stabilizers, and keycaps that fit the layout. we will make a bill of materials available that will allow you to purchase almost all of these parts from either newark, digikey or mouser in a few clicks.

note above that i have not priced the stabilizers into the kit. i may be able to sell these separately, but i will have to look into it. in the meantime, they are available from several popular geekhack retailers. for, as far as i know, pretty reasonable prices.

i have also not priced the teensy into the kit. i will be selling the teensy separately, as there are a bunch of teensies running around due to jdcarpe's recent buy, and i don't want to make people buy an extra teensy. i will also provide a small piece of hookup wire with the pcb that can be used to connect the USB data line to the teensy.

i will NOT be providing construction services, only kits. we WILL write up instructions on constructing the keyboard, with pictures, maybe some video, etc.

not too sure about pcb mounted vs plate mounted.  I would guess that plate mounted requires a plate and pcb mounted requires the cutout in the pcb.

I'm a little bit worried about the SMD work etc. as my soldering expertise is minimal. The idea was that by building this board myself I would learn a bit more, but I'm wondering if it might be too big of a jump from switch / led soldering.
