[IC] Alps Revival - Keycaps, PCBs and much more

[MOZ]

Alright, let me start of by saying that I love Alps switches and I needed me some keycaps and PCBs to build the keyboards and use the keycaps on, and thus began the journey.

Keycaps:
I've discussed with SP, and we can do an Alps keycap GB, profile would be DCS, legends will be double shot and we will have all the legends otherwise available for MX DCS.

Regarding the stabs, in Calavera's earlier attempt it was discovered that there were many variations and it wasn't possible to cover them all, taking this into consideration, I've decided we should do Alps mount for switch and MX-compatible mount for stabs. This means that we can use Cherry stabs or costar stabs.

I am yet to get word on the available spacebars, besides that any keycap that is available for MX DCS will be available to us.

Now we need to decide on what colorway we want to go with, and from their I can start making mockups. Also Cherry legends or WYSE?

The actually GB for the keycaps will be done on the SP system.


PCBs:
To use the keycaps, one needs keyboards, there are a few PCBs out in the wild, such as the Leeku 1800 and the Duck Mini V2. I am working on converting the GH60/GHPad/Ergodox/TKL to support MX and Alps to allow for all sorts of combinations.

I will not, and I repeat I will not do a GB for any of my PCBs, they will be opensource and anybody can do a run.


Switches:
New Matias switches can be bought from MechanicalKeyboards.com as well as 7bit over on Deskthority.


Plates:
I have no idea where to source plates from, so if someone wants to help out, that would be great.


Cases:
The attempt will be to be able to use existing cases and design the PCB so that it can be used witch plates similar to those already in existence and thus compatible with existing cases. This is true for 60% as well as TKL.

[Pacifist]

fck yes alps

[MOZ]

I am almost done with the GHPad conversion. Will make a parallel thread in "making stuff" subforum on progress on conversion of various PCBs.

Lets start discussion on possible colorway for the keycaps. I'm thinking the blue-green color SP did the TKL set with:
with Cherry legends.

[Pacifist]

Can TaiHao do ALPS?

[MOZ]

According to their website, yes. However I don't know what options they have with the stabs, and it is OEM profile, which isn't that great.

with Cherry legends.

I would buy this set.  I'm not obsessed with Alps, but it would be fun to get a set other than white or black, so I'd definitely be in.

[nubbinator]

I'll be in for a cap set no matter what. Two if we do more than one color way.  I'd love to see DSA Alps caps, if possible, but DCS is good too.  A functioning Alps sets of any kind would be awesome.  It might be nice to also see about a modifier run as well so people who have found cheap Alps sets can just get the caps to make their sets funtional.  I know I've got some Dolchish ones I'd love mods for.  Since Alps boards tend to be cheap and somewhat plentiful, that might be a nice intro for people.  Just buy an AT101W for $20-30, use those switches and Alpha caps, get a PCB and modifier set and you're good to go.

A 60% Alps PCB would be amazing.  I'd grab at least two, especially if they had through hole diode and LED support so that we didn't have to do SMD soldering.  Total lack of SMD work would require a Teensy, but would probably lower the production cost enough to get more people on board.

This is about where I stand on caps. I'll gladly buy a set for eaqch colorway done. As for PCB, I'd also love a 60% alps board as long as we can do a plate and make it fit in a poker case =D

[Pacifist]

What's sprit's status for the Alps?

[Beca]

I'm definitely interested. I would like to see how sprit's gb works out too

[nubbinator]

What's sprit's status for the Alps?

Same as the current GB.  Someday it will be done, but there's no timeline for anything.

[MOZ]

SP can do DSA as well, so that is a possibility for the future, they can also produce keycaps in PBT but those will be blank no dyesub and they don't plan having the facility in the near future.

I too was thinking about also having a modifier pack for the Dolch-like caps, I too am getting a set and that seems to be one of the more popular one due to a the eBay sales. However those are closer to OEM profile, so there is a profile mismatch and the reason why I didn't give it much thought.

Having through hole diode, through hole resistor and LED is very hard with the controller stuff on board, maybe possible with a Teensy. How about LED + SMD diode and pick n placed controller parts.

[nubbinator]

I'm just thinking cost and ease of access.  I know the cheaper it is and easier we make it to assemble, the higher the potential that more people get on board with it and the more viable it is to do small scale runs.  I'm being selfish in wanting LEDs since I have Greens, switches made for LEDs, but if a lot of people scrounge their Alps or just do Mathias Alps, LEDs would be less of an issue and would require more thought in design since you'd want SMD LEDs and SMD LED resistors.

Through hole diode and Teensy makes it so that fewer people have to rely on someone else to do the soldering for them. Anything that makes it easier will make buys more likely and more enticing to more people.

[riotonthebay]

I'd definitely be interested in this group buy.

One thing that comes to mind is that many Alps boards (e.g. SGI Granite, Dell AT101) have an offset CapsLock where the stem is lined up with the Tab stem above it. So it's offset, but not as offset as a Cherry offset CapsLock. Do you know if SP has this mold?

I'm on board.

[mashby]

I'm in.

[nuclearsandwich]

Can the Duck mini's Alps plate actually support Cherry Stabilizers?

If we go this route we may have to start completely from scratch. I don't have any spare stabilizers at the moment but I do have an Alps plate for a Duck mini. I'll get some Costar stabilizers from WASD and a test those. I should be able to test cherry stabilizers on it in the next week or so.

No, it can't. On that note, I don't actually agree with the decision to use Cherry stabilizers. We'd need a separate group buy for plates which seems like a huge PITA. I'd love to be able to use these caps with existing Alps plates.

I don't believe so.  They have the same stabilizer mounts as Dell AT101W

Yes, this is true. Also the same as the AEK II and a number of other common Alps boards.

[MOZ]

Let me clear this, what I meant by Cherry-compatible stabs, was the mount on the keycap (The +), so you can use costar, you won't be able to to use the rectangular Alps style though.

If I understand correctly, many of the later Alps boards too used costar stabs.

[Puddsy]

in

[geniekid]

I'd rather have blanks but Alps caps aren't exactly easy to come by so I'd probably get one of these sets anyway.

[MOZ]

Just got word that spacebar is only available in DSA alps, not DCS.

[dorkvader]

Cases:
The attempt will be to be able to use existing cases and design the PCB so that it can be used witch plates similar to those already in existence and thus compatible with existing cases. This is true for 60% as well as TKL.

more like:
Cases: Don't need a case if you got ALPS! Bare PCB and rubber bumpers on the desk.

[jacobolus]

If you make an Ergodox PCB, MassDrop would absolutely love to offer a Matias switch Ergodox (according to the guy at MassDrop responsible for keyboards).

Only thing I’d be worried about with that is that Alps switches won’t work quite as well as MX with the super thick acrylic plates. (The little plastic clips that hold the switches into a plate will just break off.)

Maybe we could design an Ergodox case to work with a bunch of layers of acrylic plus one layer of metal plate, to fix that problem. I think MassDrop might be able to get a reasonable number of purchasers and some supplier in China to make the metal (1.5mm thick aluminum or something) plate viable.

[jacobolus]

SP can do DSA as well, so that is a possibility for the future, they can also produce keycaps in PBT but those will be blank no dyesub and they don't plan having the facility in the near future.

I would love love love some blank PBT Alps caps. Especially DSA, but DCS would be okay too. I mainly just want a pile of 1x1 caps, and maybe some 1.25x1 / 1.5x1 caps. They had some Alps caps for sale as inventory, but only blank gray ABS DSA 1x1s, for $1/each.

Why can’t they do dye-subs for Alps? They seem to be able to do them for MX mount caps. I wonder what the difference is

However those are closer to OEM profile, so there is a profile mismatch and the reason why I didn't give it much thought.

I’ll try to take a picture of the profiles for various Alps caps. Those Alps-made ones (for Toshiba, etc. laptops) in particular are definitely lower than OEM profile.

Having through hole diode, through hole resistor and LED is very hard with the controller stuff on board, maybe possible with a Teensy. How about LED + SMD diode and pick n placed controller parts.

LEDs are so overrated. :-)

I think these boards use Alps-style stabilizers, so SP caps don’t work anyway. You need a new PCB/plate.

[jacobolus]

Switches:
New Matias switches can be bought from MechanicalKeyboards.com as well as 7bit over on Deskthority.

Or directly from Matias in boxes of 200 switches. 7bit might be cheaper though, as I think he bought the larger sized boxes.

[MsYutai]

I'm interested... if I can get complicated Blue ALPS. I guess the original switch is hard to come by so I will definitely settle for the knock-off blue alps. They sound super awesome.

[jacobolus]

I'm interested... if I can get complicated Blue ALPS.

You need to hunt around on ebay then. Used keyboards with blue Alps are typically about $80-100.

I guess the original switch is hard to come by so I will definitely settle for the knock-off blue alps.

There aren’t really any knock offs of blue Alps, per se.

But you can get complicated white Alps, which are similar, with a bit heavier spring.

Or you can take the housing + slider + spring from an orange Alps switch, and add the click leaf from white Alps or Matias clicky switches, and then optionally slightly bend the click leaf to a more acute angle (i.e. slightly reduce the clickiness), and you’ll get something very close to blue Alps (though not 100% identical). The blue switch spring is very slightly lighter than the orange switch spring.

[katushkin]

Yes please. I've been meaning to look into getting more than MX switches, and I think it's time I dived in headfirst to a big GB.

[SonOfSonOfSpock]

An Ergodox with Alps sounds pretty awesome. I'm in if that's where this leads.

[AKmalamute]

Can someone more technically minded then I, finish what I started?

Attached is a file created in Inkscape; it's an SVG of the layout I want, in ALPS, but with a jpeg 'imported' for reference.

Also floating in the middle of the layout you'll find a bright shiny square. It is precisely the size one should expect between plate holes' edges -- just don't rotate it, and it will work for both height and width.

But I've never seen one of the cases it appears to be trying to match with so the mounting holes are just by guess and by-golly.

 Also the plate, as it stands now, has no edges. Just an infinite piece of metal with a few cut outs, just here.

Edit: LOL maybe this could go into, I don't know, 'making stuff together' ?

But 1st: I'm interested in getting an ALPS keyboard. See attached
and 2nd: once this is fixed, I think it would be okay to leave it hanging in a thread about ALPS plates and parts. Maybe someone will do a GB to make the idea a physical thing.

 Also I didn't see a handy ALPS thread in 'making stuff' that caused me to pine for reason of my lack of drafting talent.

I was able to pick up the Rosewill RK-6000 which has clone blue ALPS! I just need to learn how to solder and potentially get in on this GB to get a sweet custom case. O_O

Do you have details on the clone switches? Have you written them up anywhere? I am rather intrigued!

[MsYutai]

There's a review on them here:
http://geekhack.org/index.php?topic=55191.0

I posted a first impressions on the bottom of that thread: http://geekhack.org/index.php?topic=55191.msg1293525#msg1293525

I think they're pretty sweet, since I've never used the monterey blue ALPS I can't compare it to those though.

[AKmalamute]

I'd actually rather have the ALPS GH60 than an alps ergodox. Someday Spirit will move forward with his Face your World ALPS-version but too, there's shipping from the other side of the world to consider.

What happens if you use ALPS switches plateless? Does it just not work at all because there's no stabilizer pin like the PCB version of the MX switches?

[Hak Foo]

The plate serves two purposes:  making the board feel more solid, and probably eating some of the force that would otherwise pound on the switches' solder joints.

I'd expect if you tried to use an ALPS board plateless, you'd suffer fastrer breakdown, because all the force of the keystrokes would be forced onto thePCB and its connections.

I offhand can't think of an ALPS-sans-plate board.

Alps switches need a plate because unlike MX switches there's nothing but the two leads that venture through the PCB like the MX center stem and PCB stabilizing tabs do. The two solder joints aren't enough to hold the switch in place even if using a board like that wouldn't rip out the traces / joints after a while.

Beautiful. Now, where do I get about 60-80 -ish of them? I'm guessing 7bit doesn't have a supplier :p

ah, well. Some day. Those look like they'd fit nicely in the single-switch PCB that's being worked on, since the board is switch neutral and those plastic pins look exactly like MX style PCB mounts.

[nubbinator]

I'm getting ~70 from Taobao.  I can share the link later.

The Matias mini keyboards are smaller than full size. They're in between TKL and 60%. Also, a few months ago Matias was talking about doing a Matias 60% GB here. I don't think anything has come out of it yet though.

An Ergodox with ALPS is no longer a pipe dream

Czarek on deskthority found out that ALPS switches are compatible with his Ergodox PCB:
http://deskthority.net/for-sale-f55/ergodox-pcbs-cases-electronics-and-assembly-services-t6972-60.html

All we need is a groupbuy for some ALPS Ergodox keycaps, or those fancy 3d printed mrinterface ALPS-Cherry keycap adaptors, and we're set for life



...dreams do come true

Edit: ****, we'd also need some custom Ergodox ALPS plates too, since most ALPS switches weren't designed to be PCB mounted.

Think Matias can help us out with the keycaps. Ive heard those adaptors are very brittle though. I've been meaning to print some out and try out though.

[Matt3o]

I'm all over this unfortunately I do no take part to GB anymore

anyway I can help with manufacturing the plates if there's interest/need.

[jdcarpe]

I can redesign the switch plate for Alps...

[Matt3o]

I have some ALPS dxf if you need them.

[jdcarpe]

I have some ALPS dxf if you need them.

If you have one with the little stabilizer holes, that would be great. Otherwise, I have some drawings with Alps switch holes I can use. I can PM you my email address, if you don't have it.

[Matt3o]

yes it is with those funky little stab holes. PM me your email, just in case.

[tree]

I'm incredibly excited for this.

All we need to do to make this project work are the keycaps from Matias, and designing and manufacturing the switchplates! So, would it be expensive to make a small order of these custom switch plates? Something to note is that from the pictures czarek posted on deskthority, it looks as if the Matias switches might not be seated completely centred on his PCB, so any switch plate we make around his PCB will probably have to account for this (although the switch plate might render obsolete or solve this problem).

Let's make this happen! I'm not experienced in any of this stuff, but I'll try my best to help in any way I can, just let me know what I can do to speed this thing along~

[dante]

Alps is a lot like Linux: Too many variants!

[pasph]

I have some ALPS dxf if you need them.

let's make also a plate that don't require stabs, like your "bianca"

[jdcarpe]

Here is the drawing file for Layer 3 (switch plate) with Alps switch holes. As always, stabilizers are optional on the 2-unit thumb keys.

[jacobolus]

Note that you should cut that Alps plate out of (at the thickest) 1/16" acrylic. 15 gauge aluminum (or 16–17 gauge steel) would be better.

For 1/16" acrylic, I think the simple rectangle shape isn’t quite ideal. I still need to do some testing though. Also, the width of the line that the laser itself cuts makes a big difference in the exact shape that should be sent to the cutter.

[AKmalamute]

Note that you should cut that Alps plate out of (at the thickest) 1/16" acrylic. 15 gauge aluminum (or 16–17 gauge steel) would be better.

Y'know, this would have been a good addition to the GB I'm running -- too bad this was drawn up a little too late.

Maybe I'll just keep the file around, hmm? Come September I may include this with the standard fare. Granted, a solid block of stainless steel runs nigh $100 plus shipping -- ask me how I know (or peruse the 'post your ergodox thread).

Somebody should print that thing from thin acrylic as proof of concept, make sure the accidental-ALPS board likes where these holes would up. I'll probably print it to paper this weekend, cut out the holes with a razor and guestimate how I like it...But JDcarpe has always done excellent work so it's probably fine.

[MOZ]

I would recommend a small test first, since the Alps switches on the Ergodox don't fit in the exact same position as the Cherry switches.

[gotofbi]

I would love to see SP Alps keycaps.

[jdcarpe]

I would recommend a small test first, since the Alps switches on the Ergodox don't fit in the exact same position as the Cherry switches.

Hmmm, I didn't think of that. Maybe I need to rethink the centers of those holes.

[jacobolus]

Oh, you’re probably going to need a custom PCB or hand-wire if you want an Alps ergodox.

[dante]

what do you guys think of a poor/working man's kingsaver:

use a cm storm qfr case, and controller. Using a PCB built for it using stabilizers from a AT101?  It could be called the Dell Saver

[AKmalamute]

Hmmm, I didn't think of that. Maybe I need to rethink the centers of those holes.

Like I said somebody needs to do a proof-of-concept with a physical plate ... but there' a cheap way to do this.

Print (on 8-1/5x11 paper) a 1:1 copy of one side of the proposed ALPS .DXF ... take an Xacto knife and carefully cut out the switch holes. Find a sizable hunk of stiff cardboard, and spraypaint or otherwise mark the edges of those switchholes. Bring the knife back and cut out the painted area, then cut enough around it you can see what you're doing. The edge shape of the drawing isn't in question so no need to be particular about that.

get at least four ALPS compatible switches, and shove them into the corners of the cardboard 'plate' -- and see if you can make the PCB fit onto the switch. From there your eyes should tell you, I'd expect, if some of the keys were just never going to line up.

Jacobulus: maybe not ... PCB mount work fine, as it turns out. But keeping the switches from rotating even a hair, as you solder them ... might prove difficult.

[engicoder]

I would also be interested in some keycaps...I refurbed an old Zenith with complicated greens that needs some keycap love.

[jdcarpe]

I just tried a Matias switch in an ErgoDox PCB, and the pins fit into the top two of the mirrored holes in the PCB. It looks like the center of the switch is about 1mm higher in relation to where the center of an MX switch would be. And of course, the pins of the switch being just slightly offset, the switch definitely wants to rotate in the hole, if not held in place by something (the plate). I could probably get the Alps switch hole in the exact position it needs to be over the PCB, but I need to look at some switch dimensions. Anyone have a spec sheet for Alps switches that shows dimensions of the pins, etc.?

[jacobolus]

See the file here, FuhuaAlpsSwitchDatasheet.jpg
http://geekhack.org/index.php?topic=33298.0

Or directly embedded here, Forward Electronics / Fuhua Alps datasheet:


This datasheet shows the “SKBM” switch (so-called “simplified white Alps” or Fukka/Fuhua switch), but the dimensions are the same for Alps SKCL/SKCM and Matias switches as well.

Various other Alps clone switches have slightly different housings, but the same pin locations, keycap mount, and plate cutout.

[jdcarpe]

Thank you very much, jacobolus. That's exactly what I need.

[mian2222]

Just expressing interest. I have been thinking about an ALPs ergodox for a while.

[jacobolus]

Note, if you’re using 1/16" acrylic for the plate, you don't want to make a rectangle quite tight to the shape suggested here, or you’ll put a lot of stress on the little plastic clips (since that’s is a bit thicker than the typical ~1.5mm plate). I need to do some more tests w/ lasercut 1/16" acrylic to figure out the ideal size and tolerances.

If you do just tell your laser cutter to cut a 15.5 x 12.8 mm rectangle, you’ll end up with a slightly bigger hole (since the laser has some thickness), so that might actually end up working okay.

[jdcarpe]

Okay, so according to my calculations, the switch holes needed to be moved exactly 0.83mm toward the holes for the switch pins. I have done that, and attached is the revised drawing which should line up the switch holes exactly where they need to be in relation to the pin holes in the PCB. The other layers may have to be adjusted accordingly, to allow for keycap clearance.

[Findecanor]

I would recommend a small test first, since the Alps switches on the Ergodox don't fit in the exact same position as the Cherry switches.

An ErgoDox with Alps would also require a new case, because of keys being shifted compared to Cherry MX, at least above the plate.
The case below the plate doesn't have to be different, but it would look better if it was. Some walls would be thinner and others thicker to compensate to give the PCB a good fit.

BTW, I am exploring the design of another keyboard inspired by the ErgoDox, fully with the intention to support both Cherry MX and Alps the way that ErgoDox sort'a does. I am quite restricted in that for a key to support both Alps and MX I am unable to rotate it, so Cherry MX would get some layout options that Alps won't. Here is my work space in QCad right now (left hand):

Interesting stuff.

I don’t understand. Can you elaborate a bit? You just mean that any Cherry keycap can go onto a switch in 4 directions, while Alps keycaps only fit 2 ways?

Hmmm does anyone know the vertical length between the foremost switch pin on a Cherry switch and the centre of a Cherry switch stem? We might be able to get away with just using regular Ergodox cases if the difference isn't that big.

Not sure I follow you, but that dimension is 5.08mm, if I'm understanding you correctly.

Then there's not much difference between where an Alps and Cherry keycap would be on an Ergodox (just 0.68mm). I don't think we have to worry about whichever case we use not fitting. Just wanted to get this niggling detail out of my head -- I'm going to visit my uncle who owns a metalshop to get those plates cut out soon. I will probably start physical work on this project next month, I'm in the middle of exam season over here haha

Not only that. When using the same pin holes for Cherry MX and Alps, the Alps switch would not be centred at the exact same place as a MX switch but shifted ~0.83 mm upwards. This means that each switch-position would need to be oriented upwards or have different pin holes for Cherry MX and Alps.

Kit keyboards for Cherry MX often have multiple layout options, such as providing a choice between stepped or centred Caps Lock or a choice between a 2u Backspace or two 1u keys. To make all the pins holes fit, some switch-positions would have to be mounted downwards or sideways... but then those pin holes can't be reused for Alps ... and there isn't always room for separate pin holes for Alps.

You can totally make a PCB which supports mounting either MX or Alps switches, centered in the same place.

You’ll have to get specific about the layout you think won’t work. Stepped or centered caps lock is a bit of a pain because among Alps keyboards there are versions with differently sized steps. But 2x 1u vs 2u backspace shouldn't be too hard.

I'm interested in anything alps (keycaps, PCBs, plates)

[Defect]

As a recent Alps convert,
Gimme a programmable 60!

And case and plate and caps and please someone do Alps novelty caps...

[terrpn]

just give me some alps caps and i would be happy!

Duck0113's DuckMini v2 supports Alps. Elton is doing a sale on them at this link.

It's a bit pricey though.  I'd love a PCB so I could make my own case or use a Pure/Poker case.

There's Melvang's enabler GB, but that's noticeably more awkward than using a true PCB. There's Spirit's FaceW project but he wants to have keyswitches in his hand when he makes that portion of his overarching GB project go live...Pretty sure the GH60 will be over and done with before that happens.

Hey, so ... after Rev. C of the GH60 KiCad files are released ... who here is skilled enough to swap the MX pins for ALPS pin? We could have a Rev.D just for ALPS 60% -- wouldn't that be awesome? I'm having a plate made in a day or two so I'll totally be ready!

I really wanna buy alps keycaps!!!!

Could we interest Gon in alps setups? People love his stuff...and you get all the programmability etc.
might increase interest in Alps in general.

[Heliosphere]

In too. Need something to put on my orange Alps. I like the blue-green colorway as well.

I don't think this is actually running anymore guys.

Guys... This is dead.
Why did this thing get bumped?
We already have the Infinity mods thread.
Go post in there or make your own thread.

[jdcarpe]

FYI, there are some Alps projects "in the pipe." Be patient, and good things will come.

Such as?

[MOZ]

Yeah, sorry, this isn't happening, I'm way too busy with real life to work on this anymore, also I have moved since this thread was created and lack the the infra to work on this anymore.

There are some other great projects along similar lines, please have a look there, I think JD's been working on something for a while, so look out for that, I;m sure it will be excellent like all his other projects.

Cheers!
