Circuits

Every board I have designed, modified or built on, grouped by project. Pick a board to turn it around in 3D.

The boards inside the hand and forearm of the bionic arm.

Shaped like my forearm. Runs the 22 servos and the control system, with an amber LED on every regulator.
Links every finger potentiometer straight to its servo's internal feedback.
Breaks out around 30 servo wires onto headers, so the main board swaps out in seconds.
The regulator that powers each servo, modified and panel-assembled.
Reads the angle of each finger joint and sends it to the connections board.

The electronics behind the dial.

Exact spots for the two magnetic encoders, a motor driver and an I²C mux, with reverse-polarity and ESD protection.

Ready-made boards my circuits are built around.

Drives the servos. Three of them sit on the arm's main board.
The two brains of the arm's main board.
The tiny controller on the thermometer's main board.

Nothing here with those filters.
