Geiger Counter Nixie Clock

by Tom Sparrow Continuing my love of vintage and interesting items, I came across a non-working DP-66 Polish Geiger counter from 1971, which I set out to re-purpose as a Nixie tube clock. I stripped out any unwanted electronic internals, measured and drilled holes to fit the Nixie clock module, drilled holes at the rear…

Kerbal Space Program: 10 Axis Controller with Arduino Mega.

by Declan Heard What could possibly make the most awesome build and fly it space-sim of the last decade even better?

Magnetic Encoder Tests

I recently purchased some magnetic encoders to use in an upcoming project and hooked them up to a Wemos D1 Mini to try and do some basic testing. The specific magnetic encoder is the AS5048. Three wires were soldered to the PWM output pins only as this is a lot easier than soldering wires to…
