Title: KMAC DIY Thread
Post by: litster on Sun, 29 April 2012, 02:07:09
People are receiving KMAC DIY kits.  I think a thread to collect all the info, tips, and tricks would be help to all KMAC DIY folks.  I will start with a few pictures of the PCB.

Top:

Parts:
- - Cherry MX switches, plate-mount or PCB-mount
diodes:

Digikey has MMSD4148 and many variants.  They should also work but I have not tried.  I only used the one from mouser.com.  use other diodes at your own risk.

Or through-hole diodes:

digikey: http://www.digikey.com/product-detail/en/1N4148/1N4148FS-ND/458603
These diodes are the same diodes I used on my Phantoms and MX Mini.  I didn't use these with KMAC.  Links provided here are for reference only.

I use part number 645-521-9901-802F (http://www.mouser.com/ProductDetail/Dialight/521-9901-802F/?qs=%2fha2pyFaduhezgLw1rty1x4KQ%252bWO2Mln%2fpYTEr0ynYH5rE5F6SnVdQ%3d%3d) at mouser.com

digikey has it as well, but mouser.com is cheaper.

Solder pads for SMD diodes already have solder on them, because they are originally prepped for machine soldering.  To hand solder, I will need to remove solder from one of the solder pads with wick first.

Post by: harrison on Sun, 29 April 2012, 13:50:51
do the tops and bottoms get removed from the PCB?  the top would appear that it has to be removed to allow for clearance on the usb connector, but that it's cut to  support the bottom of the connector still (a very cool design if that's correct).

Yes, I believe the top and bottom need to be removed.

digikey has it as well, but mouser.com is cheaper.

both solder pads for each SMD diodes already have solder on them, because they are originally prepped for machine soldering.  To hand solder, I will need to remove solder from one of the solder pads with wick first.  

I could just solder through-hole diodes, but I already did that a couple time on Phantom.  So I will give SMD a try next week when my diodes are here.  I hope I won't ruin my KMAC :-)

As far as SMD goes, those are big.  You'll have no trouble at all if you've been soldering anything.  Just need to hold the bugger down so it doesn't float on the solder.

Received my diodes from mouser today.  Did a couple of them.  Wasn't too hard.  The printing on the diodes are too small and too faint to really see.  I used a magnifying glass with a flash light to read it.   Also used a multimeter to confirm the black strip.

Since the diode pads are already prepped, I had to use wick to remove solder from one of the pads before I can solder.  I may do a video later.

You should teach people how to clip the cherry stabilizers.  I took nearly 2 hours to figure out how to put the damn thing together.  The pictures didn't help me. 

Well, finally, my finished KMAC with Linear 55g!

Here are the two KMACs I built:

KMAC winkey Titanium with Dolch double shots + Hashbaz's Dolch Moogle + Hashbaz's Red Cherry font Enter + the mystery keycap I just received.
(http://geekhack.org/index.php?action=dlattach;topic=21911.0;attach=2574;image)

This is a KMAC winkeless Silver with 2 sets of Cherry dye sub keycaps.  One set is just plain black on beige Cherry dye sub.  The other set RGB dye sub with some special print caps.

Hey litster - can you tell me the specs for the LEDs you used? i want to make sure to get the right ones.
Title: Re: KMAC DIY Thread
Post by: litster on Thu, 30 August 2012, 21:28:06
I chose some LEDs that are not very bright.  If you use caps with an LED window, these are good enough.  If you use regular caps, then you will want LEDs brighter that what I picked.  I only soldered LEDs for caps lock and scroll lock.  I didn't install LEDs to the function keys and WASD.

Green: http://www.mouser.com/Search/ProductDetail.aspx?R=WP710A10SGCvirtualkey60400000virtualkey604-WP710A10SGC
Blue: http://www.mouser.com/Search/ProductDetail.aspx?R=VAOL-3LSBY1virtualkey59300000virtualkey593-VAOL-3LSBY1
Red: http://www.mouser.com/Search/ProductDetail.aspx?R=WP710A10ECvirtualkey60400000virtualkey604-WP710A10EC
Orange: http://www.mouser.com/Search/ProductDetail.aspx?R=WP710A10EDvirtualkey60400000virtualkey604-WP710A10ED
Yellow: http://www.mouser.com/Search/ProductDetail.aspx?R=WP710A10YTvirtualkey60400000virtualkey604-WP710A10YT
White: http://www.mouser.com/Search/ProductDetail.aspx?R=521-9901-802Fvirtualkey64500000virtualkey645-521-9901-802F

I bought 10 of each, but I only used white.  The other should work, too.  I just didn't solder them on to any keyboard.

Basically you want T-1 size 3mm, around 3.5V forward voltage.  The white ones I am using now is 1100mcd brightness.  You could use something dimmer if you use windowed caps.  If you use regular caps, you might want something brighter.  Also some people are getting creative with UV LEDs.   :)

Okay, forgive me for being a complete newb to this but what are the diodes for exactly?
Title: Re: KMAC DIY Thread
Post by: litster on Fri, 19 October 2012, 18:35:41
you need diodes if you want 6 or more KRO.  Diodes allows electricity flow only in one direction.  Without diodes in the matrix, either ghost keys maybe registered when more than a couple of keys are pressed at the same time, or only 2 keys are registers when you have 3, 4, or more keys are pressed.
Title: Re: KMAC DIY Thread
Post by: alaricljs on Fri, 19 October 2012, 18:36:06
Diodes are one way doors for electricity.  What they do is allow you to detect what switches are closed and know those are the only switches closed.  Otherwise some switch combinations make it seem as tho other switches are closed when they aren't actually.

Ha! Thanks guys. I've just received a pm that I snagged a KMAC, so I'm sure you can understand my excitement with being able to get this DIY project working. Which means...

...lots of questions...

thankfully you guys are the bees knees... so....

how do you know where on the board to solder these diodes? And how many do you need on the board?

Also... I'm curious as to how to get led lights working on this board. I know you have to buy the lights but how do you get them working on the board.

Now, I'm new to soldering but I'm eager to learn and I want to do this on my own. However, I also don't want to destroy the board. Do any of you guys have any advice for me that would help me along the path to success once I start building this board?

Post by: bpiphany on Sat, 20 October 2012, 02:40:58
I just want to clarify that you really only get 2KRO without diodes. There are always going to be combinations of 3 keys that doesn't work. There are also going to be a lot of combinations that work, but it is the worst case that counts.

One per switch, and it should be quite obvious... Although I must admit I didn't have a look at it =)

Ok, so either through hole and internal to the switch, or SMD and on the back of the PCB beneath each switch.
Title: Re: KMAC DIY Thread
Post by: WhiteFireDragon on Sat, 20 October 2012, 05:41:45
Whats recommended through hole or smd diodes?

Functionally the same, but if you're going to do it by hand, I would think through-hole would be easier. SMD was meant for pre-assembly at the factory I think. No reason why you can't do SMD yourself though.
Title: Re: KMAC DIY Thread
Post by: bpiphany on Sat, 20 October 2012, 05:51:01
Once you get the hang of it, these SOD123 (I presume) diodes are quite nice to do by hand. In this case through hole would also require you to open each switch to insert diodes (if you don't already have switches with them included). And open ~100 switches is a real pain =P You could probably do a half-dodgy version soldering through hole diodes from the back with their leads precut to just go into the pad holes.
Title: Re: KMAC DIY Thread
Post by: alaricljs on Sat, 20 October 2012, 07:49:08
Well most of these guys are opening switches for stickers, lube and whatnot...  A little diode isn't going to add much time.
Title: Re: KMAC DIY Thread
Post by: litster on Sat, 20 October 2012, 11:22:44
You could use through-hole diodes without opening switches by soldering the diodes onto the back of the PCB and solder the diode legs flush to the switch-side od the PCB. 

SMD diodes work best though.

87+ switches (spares!)
87+ diodes, 1n4148 or some form of fast switching diode that fits either the SMD footprint or the thru-hole.  Those round SMD ones can be a ***** cuz they rollin.
20 3mm LEDs (Caps, LCtrl, WASD, Most of the F-row)  flat top, no shoulder (also called column) will require no mods.  It's not hard to cut shoulders off though, but sanding 20 domed LEDs flat can be painful on your fingers and I don't recommend trying to do it any other way.
4 2x Cherry PCB mount stabs
1 spacebar Cherry PCB mount stab (6.25x or 7x depending on your keycap set)
1 set of keycaps to fit your layout (offset caps is possible, mod-row is kit dependent)

bling the switches however you want, stickers, grease, TLC.  I recommend paying close attention to your choice in LED light out put (mcd) since they all get the same amount of power and it can be disappointing to be blinded by blue and have the red/amber/yellow sedate and laid back.

If you have never soldered anything before, I say you pay someone else to do it for you.  alaricljs is very good at this.  If you do it yourself, you are going to make mistakes and may ruin your KMAC.  You should buy some cheap solder projects from Radio Shack for practice.

No resistors are needed for the LEDs.  Think about it, there is no place to solder resistors on to the PCB, unless you want to solder a resistor inline with each LED.

As I wrote in the first post, that mouser SMD diode part is the part I used in my KMACs. 

If I have to guess, the keyboards you use are all broken in some way, especially the comma and period keys.  You shift keys don't work most of the time as well.

If I have to guess, the keyboards you use are all broken in some way, especially the comma and period keys.  You shift keys don't work most of the time as well.
You are correct and are the first to say something on this forum about that. Also besides that my typing style is atrocious.

I have a piece of one on my desk, so part of the answer is... They were already available... perhaps you can get one now if you try?

Are we talking about the tenkeyless KMAC or the mini?

Also, can anyone recommend a good soldering kit? I've never soldered anything before and I'm kind of worried I'm going to mess something up. Any suggestions on a way to practice before going straight to soldering on the board?


There is not much to soldering, but it does require at least $50 investment in equipment. I built/modded a few keyboards, and I shot a video for one of them. I'll upload the video tonight on youtube, and you can see how easy it is. Litster also posted a video in the OP of the SMD soldering, but those require a tad more precision than through-holes.

The mini... have the plate/PCB from someone else's board.  I have built ~5 KMAC 87s.

Also, that's $11 worth of LEDs or you can go to ebay (http://www.ebay.com/itm/100-pcs-3mm-10000-mcd-Round-Red-Superbright-Led-lamp-/200715407673?pt=LH_DefaultDomain_0&hash=item2ebb921139) and get them for way cheaper and have a ton of leftovers for resale or friends...  They claim 10kmcd,which is a bit much but they are definitely going to be stupidly bright.

I have a question about diodes. I have a whole bunch of vintage blacks, believe they still have diodes in them. Maybe they don't, can't check as they are not with me right now. But say I was going to install these in my KMAC, would I be able to use the diodes already in them, or should I buy all new diodes?
Title: Re: KMAC DIY Thread
Post by: alaricljs on Sat, 20 October 2012, 22:18:41
I would recommend new diodes since they are so cheap (penny a piece or less) and then you don't have to worry about fixing any bent or broken leads and making sure that they're not dead.

For stabilizers, you can find their part numbers here: http://www.cherrycorp.com/english/switches/key/mx.htm (http://www.cherrycorp.com/english/switches/key/mx.htm)

2x/2.5x/2.75x PCB-mount stabilizer: G99-0742
7x PCB-mount stabilizer: G99-0745
6.25x PCB-mount stabilizer: doesn't exist, need to make your own with 1/16" piano wires.

I don't know where you can find them.  Mouser and digikey don't have it in stock.  Last time I had to buy plate-mount Cherry stabilizers to test with the Phantom prototype, I had to buy from onlinecomponents and newark, neither shipped all the pieces to me, both missing the metal bars, and one of them only sent me the base, no inserts.  I think both onlinecomponents and newark have the same fulfillment center.

octpart can tell you where else you can find these parts.  You can try other vendors.  http://octopart.com/partsearch#search/requestData&q=G990742

If I order from http://canada.newark.com/jsp/search/productdetail.jsp?SKU=98B1432&CMP=AFC-OPG&CMP=AFC-OPG will each order come with both inserts and the metal bar? So I would need 4 of them? Or since you have issues with them getting it right, order several extras.
Also to make the 6.25 stab, could I order the 2x kit, and just put in the piano wire? Although I think I'd post a wtb before it comes to that.

I chose some LEDs that are not very bright.  If you use caps with an LED window, these are good enough.  If you use regular caps, then you will want LEDs brighter that what I picked.  I only soldered LEDs for caps lock and scroll lock.  I didn't install LEDs to the function keys and WASD.

Green: http://www.mouser.com/Search/ProductDetail.aspx?R=WP710A10SGCvirtualkey60400000virtualkey604-WP710A10SGC

White: http://www.mouser.com/Search/ProductDetail.aspx?R=521-9901-802Fvirtualkey64500000virtualkey645-521-9901-802F

I bought 10 of each, but I only used white.  The other should work, too.  I just didn't solder them on to any keyboard.

Basically you want T-1 size 3mm, around 3.5V forward voltage.  The white ones I am using now is 1100mcd brightness.  You could use something dimmer if you use windowed caps.  If you use regular caps, you might want something brighter.  Also some people are getting creative with UV LEDs.   :)

Ok... I've been looking at leds today and trying to figure out which color combination I'd like to get. Some of the links above have a very low mcd, like 45, and some of them have a much lower than 3.5V forward voltage. I just want to make sure I get the right thing. Since I'd like to get different color combinations, I'd like for them to all be the same luminous intensity. Also, what can we do with the UV LEDs. This intrigues me...

I noticed the UV lights are listed with Wavelength/Color Temperature instead of Luminous Intensity of the other leds. I don't see anything about the intensity of the UV lights on mouser. Is higher Wavelength/Color Temperature better? If so... this is what I've found...

Post by: ekw808 on Mon, 22 October 2012, 15:21:46
The ones I have been using are only 400-600 MCD which means they are pretty dim and not that bright at all barely noticeable under CC's, and they shine through as the color of the CC. I'd say anything around 2000 would be pretty comparable to the red/green/blue ones people usually get.

So i discovered this when trying to remap keys.
You get kmac layout, kmini layout and kpad layout xml files with corresponding temphex files.
My initial action when editing source is to copy it and work on a copy... unfortunately kmacs.exe does not generate a temphex file, only a real hex file.

SO if you change the name of the layout xml file you won't be able to generate hex for it... so make a backup of both and edit the original :)

How I soldered SMD diodes onto my KMACs is specific to KMACs and may not be needed for other keyboards that support SMD diodes. 

On KMACs, both solder pads for each diode location is prepped with solder.  Unless you can melt solder on both solder pads at the same time, you can't solder the SMD diode flush to the PCB surface because the other un-melted solder will keep your SMD diode tilted to one side. 

I removed solder for one of the pads with wick or solder sucker pump.  After that, I get ready to solder the SMD diode in place by melting soldere on the other pad.  Once solder is melted, I slide the diode in place and make sure it is flush to the PCB surface.  Then I just add solder to the other side to lock it in place. 

Hope this helps.

So i discovered this when trying to remap keys.
You get kmac layout, kmini layout and kpad layout xml files with corresponding temphex files.
My initial action when editing source is to copy it and work on a copy... unfortunately kmacs.exe does not generate a temphex file, only a real hex file.

SO if you change the name of the layout xml file you won't be able to generate hex for it... so make a backup of both and edit the original :)

I didn't change anything inlude the file name, but still couldn't generate a HEX file ... Anybody could help me out? T_T

Maybe many of you already known this, but some still may not. As it took me about 2 hours to figure out, I think I should write this down for whom have KMAC winkeyless with LEDs installed to TURN THE LEDS ON/OFF.

So here we go:

1. Download the New KMAC Keymap tools as provided in litster's OP.
2. Download Flip application via URL provided in the How to upload to KMAC.docx (Thanks to feng ^^), and install it.
3. Follow the How to upload to KMAC.docx to generate you own HEX file and upload to you KMAC winkeyless. Some IMPORTANT points to be aware of here:
     - Extract the New KMAC Keymap tools to a directory without any space in the name, e.g. C:\KMAC, otherwise, it can't generate a HEX file correctly.
     - When starting the KAMCS.exe, you are first required to use your KBDMania account to login. (The login window is in Korean...)
     - Assign one of the keys except the Esc as Fn, in my case it's my right alt. please also keep in mind that once the key is assigned as Fn, the original function of that key will never work again.
4. Once the new key map file (a .HEX file) successfully uploaded to your KMAC winkeyless, you can use your new Fn key + Esc to turn on/off the LEDs installed on your board, and you will surprisingly find that LEDs in different areas, i.e. ASDW LEDs is viewed in one area,  can be controlled separately.  Congratulations ;D

Please let me know if you have any questions  regarding to the above, I would be happy to be helpful. ^^

Here is the translated manual that I did in Google Translate...not the best, but helpful if used side by side with the KBDMania manual. It most importantly to me told me the DFU keys for the KMAC's is the Caps Lock key and for the KPAD, it is the Fn key. Also included is the syntax for macros on the KMAC's which is pretty handy.
Here...be kind to my Dropbox. (http://db.tt/CXWOkPIt)

Got a KMAC 2 PCB here. Got it all soldered together, went to plug it in. Windows says the USB device is not recognised, but then it says it successfully installed the drivers. Caps LED on the KMAC comes on. Then I saved the hex file, etc. using the KMAC program. I then unplugged it and plugged it back in while holding caps to put it in programming mode, but this time I get no messages from windows and it doesn't show up as a device in device manager like it should. I'm unable to load the hex file using flip, as it cannot find a USB device. Worth noting that I have cut up this PCB quite a lot and I've connected it through USB using the pinouts not the USB connector. I wouldn't be too surprised if it's broken, but I'm hoping there's a fix to this.

Post by: cgbuen on Mon, 03 February 2014, 19:19:28
I received an assembled WKL KMAC a while back and noticed some troubles with KRO, but really procrastinated in figuring out the issue because I didn't have any Allen wrenches to open it up. (I only just received a set of them today, and it looks like 5/64" works.) I have the "KMAC WOW 1.3" PCB version.

Basically, the issue is that I'm not properly getting more than 2KRO. More specifically, I'm getting this one particular strange issue with alpha keys where if I hold down 2 characters on different rows but on the same "column", then hit a different character on one of those same rows, an extra keypress of the related-column-key of the row not typed is registered. (This is probably confusing, but read on.) It's a little problematic due to my typing style/speed.

For example, if I'm typing the word "just" really fast, there's a chance I'm registering both "J" and "U" simultaneously while I'm hitting the "S", the "W" comes in and I get "juwst". Or if I'm really on a roll on typing fast, then as I'm hitting "T", the "G" can come in quickly too and I can get "juwstg". (This is hard to screencap on keytest applications since I have to hit the PrtSc key while typing, but on a QWERTY layout you can see the relation between "W"/"G" and "S"/"T" respectively.) Additionally, modifiers can get really weird - like RAlt being registered when hitting spacebar, or Ctrl+Right Arrow combo not registering, and so on.

That said, the LED keys - WASD, F1-F12, Esc, Caps Lock, etc. - did seem to be fine and get 6KRO when isolated from any other problem key.

Because it was a KRO issue, I thought whoever built this might have just not soldered on any diodes, but I found some interesting things going on when I finally opened it today. It first looked to me like there was both SMD and through-hole diodes soldered on, ...
(http://i.imgur.com/Tneuctl.jpg)

... But it seems as though what's in each switch is a jumper wire. My Google-fu is a little weak in finding out reasoning behind a choice like this; if I was building this from scratch jumper wires wouldn't even cross my mind and I'd just do either SMD or in-switch/through-hole diodes (and not both).
(http://i.imgur.com/ZfjKyn4.jpg)

Before I get my hands messy with anything, I'm just wondering if there's any manual-soldering solution to this, or if it's just some kind of debouncing problem that can be solved through firmware adjustments. Anyone have any thoughts?
Title: Re: KMAC DIY Thread
Post by: litster on Mon, 03 February 2014, 19:53:31
LOL, that looks like a bad build.  The jumper in the switch effectively by pass the diode.  2KRO is what you get then.  To fix it, you would need to remove all the switches, open up all the switches, remove the jumper inside each switch, and solder the switches back on to the PCB again.

Someone f**ked up.
