(Not new ones, but old still deployed ones still have them) https://upload.wikimedia.org/wikipedia/commons/5/51/Salemer_M%C3%BCnster_Orgel_innen_Pneumatische_Traktur.jpg https://upload.wikimedia.org/wikipedia/commons/5/51/Salemer_... https://en.wikipedia.org/wiki/Tubular-pneumatic_action https://en.wikipedia.org/wiki/Tubular-pneumatic_action
- dwringer 7y agoThis made me recall reading about Douglas Engelbart's project from SRI (whence the computer mouse originated) that used a 5-key chording keyset that had pneumatic actuators for using the keys to output a data stream to the user haptically (from my reading it was unclear if this functionality was ever intended to be put in the mouse as well, which was used in the opposing hand). I wonder if anyone is aware of any existing modern (DIY?) projects to bring such a thing back to life?
