Servo Mounted Phone Tapper

thingiverse

This is a smartphone tapping device attached to a servo horn, designed for precise control over stylus placement. Custom-made styli like the one shown in [http://a.co/htD1zzX] are inserted into side holes on this device, providing a secure and reliable connection. To ensure proper grounding of the styluses, I've found that running an unbent paperclip between both points works effectively, but there must be a more efficient solution. The spacing of the attachment holes can be adjusted based on individual needs, depending on the specific servo motor being used. Some servos may require a larger or smaller hole size, so it's essential to customize accordingly. I've chosen to mount my servo on a lego servo mount for easy positioning, but a setup with threaded rods would likely offer greater precision and stability. To control this smartphone tapping device, I use code similar to the example shown in [https://learn.adafruit.com/adafruit-arduino-lesson-14-servo-motors/arduino-code-for-sweep]. This code enables smooth and precise movement of the servo horn, allowing for accurate stylus placement on a variety of surfaces.
