Project Description
A while back I saw this post on Geekhack about the numpad GH80-3700 from Cherry. Long story short: I wanted one, too. Since they’re no longer manufactured I created a listing notification on eBay and got lucky after a few months.
Time to start modding: I cleaned everything, bleached the case, modded the existing Cherry MX Black switches, replaced the PCB and plate and finally soldered/assembled everything back together.
Check out the detailed list of modifications, image gallery, (semi professional) before & after comparison and the short video of the startup audio below!
Mods
Bleached case with ready to use Retr0bright alternative
Cleaned and lubed stabilizers with Krytox 205g0 and dielectric grease

- Filmed the switches with TX films
Installed replacement PCB by anykeys.eu including AST1109MLTRQ audio chip
Installed replacement custom POM plate (cut by snijlab.nl)
Built and flashed custom QMK firmware with the USSR anthem as the startup music
