mysterium VS qmk_toolbox

All the files and instructions are in the designer's Github repositories, see https://github.com/coseyfannitutti/mysterium and https://github.com/coseyfannitutti/discipline

Started with the mysterium TKL case and reduced it to the footprint of the h88 (basic F13 TKL). Had the plate layer cut in 304 stainless steel by sendcutsend and the rest in acrylic by ponoko. Built with H1 switches. The top color layer (mysterium should have a clear layer then solid) is ivory to match most keycaps.

Put the multimeter on continuity mode, which is where it beeps as you put the two probes together. Then go from pad to pad. The ones that should beep, are the ones connected together because they are duplicated on the USB C, but they are never next to each other. Double check the wiring schematics, Mysterium is available on GitHub.

I followed the instructions here and tried typing the make, make flash and make fuse commands. I edited the code to make sure that the programmer in the .inc file is USBasp as per cftkb's instructions here.

I’m wanting to buy a Mysterium but I’m only able to get my hands on the v1. Will the case that u/coseyfannitutti released (https://github.com/coseyfannitutti/mysterium/tree/master/case) work with the v1?

The github files have the instructions on how to get it made at ponoko. cost me about $90 for the kit with pom plate. https://github.com/coseyfannitutti/mysterium/tree/master/case

Flashing custom firmware - the current version QMK tool off the website won't work. You'll most likely get a "USB device connected (NO DRIVER): WB Device in DFU Mode " and not be able to flash anything. You will need the beta version that supports WB32 flashing utility. I grabbed mine from the GMMK guide QMK tool from GMMK

You first have to download QMK toolbox https://github.com/qmk/qmk_toolbox/releases/download/0.2.2/qmk_toolbox.exe. Once downloaded, download this bin file https://github.com/GHv4/Sense75-CAPSLOCK-UNDERGLOW/blob/main/sense75-CAPSLOCK%20UNDERGLOW.bin. Open the QMK toolbox exe file, then hit the open button. Locate the .bin file. Hold Right FN+BACKSPACE until it pops up in QMK Toolbox. Hit flash and wait for it to finish flashing. Via and Vial compatible. YOU'RE WELCOME FRIENDS!!

Flash it with qmk toolbox: https://github.com/qmk/qmk_toolbox/releases

I got things working by using the https://github.com/qmk/qmk_toolbox project, and the firmware file you linked. As you said, my pad now works with Vial, and has 12 layers. Though the layer selector still only traverses between layers 0 through 3.

- QMK MSYS: you'll need it for many things, for compiling your firmware file and for flashing, especially if flashing with QMK Toolbox isn't permitted in firmware settings (in this case QMK Toolbox just won't recognize your keyboard);

I am currently using the QMK online configurator tool to do the compilation and download the resulting .bin file, and then the QMK Toolbox to flash it onto the keyboard.

Check out this site: http://kpchn.com/s/PoHJ. I found it from the AliExpress page and it leads to all the VIA/VIAL configs for the KPRepublic boards. Go into CSTC75 and you'll see a .hex file, that's the firmware. You should be able to use the QMK toolbox: https://github.com/qmk/qmk_toolbox to flash the firmware.

When I first plugged them in, my Mac (running 13.1 Ventura) recognized them as a USB storage device. I was trying to use the QMK toolbox to flash the firmware onto them, not realizing that I needed to drag and drop a .uf2 file instead of trying to flash a .hex file.
