Keyboard Key Pusher with JF0826 solenoid

thingiverse

This is a prototype of a key pressing mechanism for having controlled velocity on keys. Adjustable in height and depth to be adapted to different keyboards, holes for fixation screws are planned in design. To mount the solenoid, glue a small piece of metal in the lower hole and use a screw through the upper hole. I use a simple MosFET driving circuit to control the JF-0826 solenoid with arduino or direct by pressing a button.
