ScottoFrog by Joe Scotto is a handwired keyboard/macropad with Bluetooth capability (nice!nano). Originally, the board was a full keyboard for single-handed use, but it can be used as gaming macropad too.
Roughly 6 months ago I was commissioned to build something similar to the discontinued Frogpad. (…) I personally don't have a use for a single-handed keyboard but the 20-key layout was perfect to convert it into a gaming macropad – Joe.
Joe 3D printed the case and keycaps with a matte filament and used the fuzzy skin setting in Cura which he thinks makes it look like concrete.
The IBM Lighted Program Function Keyboard (LPFK) was used as an extra input device when doing computer aided design on the IBM RS/6000 series of machines. Posted by epearl-tv.
