How to Install MX Switches

 

In ThumbsUp! keyboards MX and ALPS switches require additional support.
In the "conventional" boards there is a separate "gasket" or a "mounting" plate which ThumbsUp! keyboards do not have. 
Instead it uses a 3D-printed panels as switch supporting brackets.
This video shows how to install switches into the brackets.

Adding a Touchpad

  Updated:   Jun 5 The unibody ThumbsUp! keyboards support ProGlide Cirque touchpads. Cirque touchpad fits nicely under the top PCB and are not visible from outside, so here its picture sticking out, not yet glued to the top PCB:     There are tracks leading to a connector on the top board. (Add it to the order and let me know if you want the connector to be installed, provided I have them in stock.)     You'd need to buy these two parts from Mouser (or any other vendor): Mouser #: Mfr. #: Desc.: 355-TM0400402024-301 TM040040-2024-301 Capacitance Touch Sensor Modules Capacitance Touch Sensor Modules 40mm Round SPI/I2C adhesive overlay 538-15166-0125 15166-0125 FFC / FPC Jumper Cables FFC / FPC Jumper Cables FFC 0.50 Type A 12 ckts lgt 127   Touchpads need to be modified: R1 needs to be removed to use I2C the boards support:   For the ProMicro and Atmel32U4-based keyboards the touchpad also needs to be made t...

Source Files and Default Firmware

Updated:   Nov 12 I am cleaning up the firmware for all the keyboards. Two biggest changes are switch to the current QMK version 0.22.14 and enabling the VIA/REMAP support for all the keyboards. Look for the banners for each keyboard to see if the new firmware is ready.   Default (pre-compiled) firmware and JSON files for VIA/REMAP are in Dropbox here:   https://www.dropbox.com/scl/fo/2s8vz5tq5lffmpjuqbz2c/h?rlkey=71amow1mhhwfe54c0ywx59bfc&dl=0   You can flash them to your board. For AtMega/ProMicro based boards (*.hex files) use  QMK Toolbox  . For RP2040 boards (*.uf2 files) press twice the reset button (on the bottom side of the middle PCB), and copy the file to the drive newly added to the system. Note: v3 (5x12) and v4 use the same firmware (use the v4 one as the latest and supporting VIA/REMAP.) //TODO: re-upload v4   v5, v8 and v8b also use the same firmware (use v5 for all of them)   If you want to modify the QMK...

How to make a ThumbsUp! keyboard wireless

ThumbsUp! keyboards can be made wireless.  Not all of them, but those driven by ProMicro controller. There are multiple options, so far I only used one of them, the nice!nano v2 with ZMK-based firmware. Nice!nano is a drop-in replacement for AtMega32U4-based ProMicro units. It got a compatible pinout and is quite simple to use. Here is how it looks fully assembled: These are the parts: nice!nano v2 in the middle, the battery on the left and the pin headers on the right. Also there is a power switch on the PCB - it physically disconnects the battery from MCU/USB. I use pin headers/sockets to allow MCU swap. The default/standard sockets are too tall, so I have to pull the pins from headers and cut them so they are flush with the board surface. Make sure solder balls are small enough to  allow the raisers/connectors to actually connect. Notice the MCU goes components towards PCB. Make sure the B+ and B- holes are not used, they are added in nice!nano, but the ProMicro does not ha...
