Hello,
thank you for the link, this is indeed a very nice project. Incredible, that with modern components which cost next to nothing (*) a replacement board can be made for the original unreliable spring-dome keyboards. I would never have imagined that these switches are small enough to fit under the keys!
In the next days I will look through my collection to see if I have some candidates which are in need of this upgrade. Lucikily my beloved and trusty Ti-59 which took me through my last years of school and all through university never had any keyboard issues.
Regards
Max
(*) At places like Aliexpress, 100 of these switches cost less than one Euro! I have not contacted the "maker" of the board yet, but I guess that the PCB will be under 10 Euros.
