In April, I ordered a remote-controlled Kindle page turner on Amazon, along with a few other devices to make reading from the couch more comfortable. The shipment was delayed… then delayed again… and eventually canceled with a refund. So I decided to build my own DIY version.

I used an Arduino Pro Mini, an IR sensor, a micro servo, and a generic remote control. The first hurdle was small but classic: the remote had no battery. I solved it with a recycled battery from another device.

The Kindle screen is capacitive, so the servo's tap needed conductivity. I wrapped the arm in aluminum foil and connected it to 3.3V to simulate a finger.

The result: a DIY page turner—functional, precise, and comfortable for reading without moving from the couch.
