A TIPRO POS converted by Alin Elena to a 8x12 ortholinear keyboard – with open-source PCB.

This is practically a tipro cash register that I got from ebay for 10 quid… is a nice 8x12 ortho that comes with cherry blacks. Used a Blackpill STM32f401 for matrix and a shift register for LEDs (there are 7 of them), practically the same I used for the tipro 8x16. firmware is qmk… – alinelena.

The conversion was based on some PCBs already used in another project of the author, namely a 8x16 conversion, stitched together by handwiring.
