80-1800 Mixed layout QMK handwired

thingiverse

FIRMWAE FOR VIA / VIAL HAS BEEN TESTED, THE MICROCONTROLLER WHEN FLASHED REGISTERS ALL KEYSTROKES CORRECTLY, AS OF RIGHT NOW IF YOU ENCOUNTER ISSUES WITH THE STOCK .BIN IT IS LIKELY THE RESULT OF A WIRING ERROR. So I've learnt basic 3d modelling and I really want to get an 80-1800, problem is there is no custom ones out there, PCBs are sold out, I cant design my own and getting a very specific layout is awkward, plus I'd like gasket mounting so here I go! This is based almost entirely off an g80-1800, the layout is practically identical aside from having a 2.25u left shift along side the standard ISO layout for the UK. The board will utilise a custom flexcut brass plate (1.5mm) from laser boost. It will then be hardwired using an STM32F411 'Blackpill' Dev board to QMK'ify it due to the large 105 keys in the layout, you will see cut outs in the the top and bottom case, these are for d65 gaskets that needs to be cut to size. Due to the lack of mounting or positioning posts the plate will be almost pressure fit so some decent post-processing will be needed there to ensure no binding, maybe a form of lubrication could help, I do not know as I have not printed it. In terms of the plate Im not sure its 100% correct but it was made in IO3 plate generator and I have seen good results from that utility so I have great faith. In terms of how a switch and keycap will sit Im not 100% sure there will be no interference between the keycap and the case edge, I have done tons of measuring and checking the cherry standard however and I believe there should be 1mm to 0.5mm gap between any wall by a switch/keycap. I hope to be able to print this in around a month's time when I acquire a FLSUN SR. Its print volume is just large enough to lay even the biggest part flat meaning no supports are required aside from inside the lower USB port placement. For the UK here is a small parts link dump for what you will need to finish. https://www.amazon.co.uk/dp/B09T325HW4/?coliid=I13FO2TI13KCS9&colid=1QC86325164S3&psc=1&ref_=lv_ov_lig_dp_it ^ STM32f411 'Blackpill' https://www.amazon.co.uk/dp/B07GZKMPJ8/?coliid=I2AB4FKJ3V0RPV&colid=1QC86325164S3&psc=1&ref_=lv_ov_lig_dp_it ^ Type C breakout board 1n4148 Diodes (105 at the least) Countersunk M5 bolts (get a mix of 10/15/20mm length as I have not tested) https://www.amazon.co.uk/dp/B09G726PYQ/?coliid=I271XX8CZKQ24I&colid=1QC86325164S3&psc=1&ref_=lv_ov_lig_dp_it ^M5 Brass threaded insert A micro USB to USB cable to butcher so it can be soldered to the break out board and Type C to whatever connector so you can plug it into your computer. Files from 'Config.h' to 'readme.md' should be in a folder called '1800mixedansiiso' in the folders 'qmk-firmware' > 'keyboards' (1800mixedansiiso will go in the keyboards folder). The file 'keymap.c' should be in the folders in this order '1800mixedansiiso' > 'keymaps' > 'default' (the keymap.c file is in the default folder). Open the 'keyboardfirmwarebuilderduplexmatrix.json' in Keyboard Firmware Builder to review the default keymap. Below is the google drive link to the respective QMK / VIAL configurations, as of yet untested, use at your own risk. https://drive.google.com/drive/folders/1UPiTzGYbrrecWLfaGMYCQizNhRvaHlNV?usp=sharing
