OK, I have time for a more complete update. I have measured the mounting holes from a Poker X, and managed to include all of them on the SD-60 PCB. In addition, I added some additional mounting holes for a total of eleven; not all of which will be easy to use in all configurations. Basically, I tried to make sure there would be sufficient support regardless of case or configuration. The diagram attached shows all of the mounting holes and slots highlighted in RED.
Regarding stock cases, I have done some test fits using the JD45, which has the same Teensy configuration. For my tests, I used a CNC-milled aluminum custom case. (I will likely repeat this test using a stock plastic Poker case.)
The PCB will fit into the case. There are some issues. First, the stock case has a standoff directly underneath the Teensy. This must be removed. The new mounting hole in the upper right corner would make a good replacement if desired.
Second, the Teensy would have to be flush mounted to the bottom of the PCB as much as possible. I used a low-profile 1.200x0.700 IC socket with resistor leads for pins, and that was a bit too thick. I'd say hard-mounted by hand would be best. Certainly the "Teensy with pins" as provided by PJRC would be too tall, so buying the cheaper Teensy and hand-attaching it would be best. This is a maybe as-is, but milling some of the case floor would certainly make this work.
Third, the USB connector on the Teensy is (a) in the wrong place and (b) too tall. Making a careful cut-out for the USB connector would solve both problems, although the resulting exit would be on the right-hand side of the case. For sure there is NOT room to route a right-angle USB cable from the Teensy to the normal exit on the back.
I can add provisions for a USB connector onto the PCB as on the JD40, but it would require removing the USB connector from the Teensy and hard-wiring from the Teensy to the PCB for that option to work. (I can probably even make it possible to re-use the USB connector
from the Teensy.
If you are are a likely buyer, and would like me to investigate alternative USB connectivity, please reply in this thread.
TL;DR As it is now, the SD-60 PCB can be used in a modified Poker case. It would be better suited to a Swill "case", a bent-plate "case", or an acrylic "layered" case. - Ron | samwisekoi
Sig auto-typed by my GH36 LH keypad.Is there an add-on option for the Burlwood desk?
Yes. Please contact me for pricing and shipping details. Delivery to Boston in Winter is not an option, but I would be happy to come out there in the two weeks of Spring -- before Summer hits!
Will there be plates?
Probably, but not from me. Actually, it should work with stock Poker plates in most configurations.
Hi,
I'm a total newbie at custom boards.
I have a Focus FK 2001 with complicated white ALPS which isn't working, and it seems that I cannot fix it.
Could I use the switches of the faulty FK 2001, solder them on this PCB, put it into a Poker II case, add a Teensy Controller and then have my own 60% custom alps board?
Is this possible? Is it that easy?
If so, I would take one.
Does it support ISO layout?
An Alps expert has to reply in detail regarding those particular switches and keycaps. I used the Matias switch mounting template for the ALPS positions.
The PCB cannot support the ISO Enter key, because it would directly interfere with the Teensy. Other than that, yes.
Extra thick pcb will not work with pcb mount stabs. 0.0945" is 2.4mm, which is greater than the 1.64mm limit in this picture

Rats. You are totally correct. This is annoying because there are just so many holes in a multi-configuration PCB, that I want it to be stiffened somehow.
I am going to try to work something out, but my suspicion is that I will fail, and the PCB will end up being normal thickness. :'(
I vaguely remember reading that the bottom row has limited configurations for Alps. Is this still true? I think I see 1.25-unit mod support but it's hard to tell.
I'm likely in for one.
Alps switches are supported on every position
above the bottom row. The bottom row has Alps support
only for ANSI (1.25x3, 6.25, 1.25x4). You should be able to see this better on the attachment to this post. I could change the Alps bottom-row to Winkeyless, but would have to lose ANSI.
I am willing to make this change if people are actually going to build using Alps in that configuration.I think that covers everything asked that hasn't already been correctly answered by someone else.
Thanks for your support!
