This repository includes various electronics projects in a sufficient state of completion to publish informally.
HighImpedanceBuffer is a two‑channel unity gain buffer amplifier with high impedance inputs and a ±17.5V input range.
SOT23ZenerTester is a fixture and set of software that can be used to obtain the voltage / current curves of SOT23‑3 case Zener diodes when used in conjunction with other test equipment.
TestSequencer is a fairly simple board that surrounds an 8‑bit PIC microcontroller with a power supply, programming header, and various inputs and outputs through ESD protected terminal blocks. I use it for controlling other equipment and running tests.
HH509R_Logger is a command line program to log temperature measurements from an Omega Engineering HH509R thermocouple reader.
Big_Fast_Switch is a sizable combination of film capacitor, N-MOSFET, and rectifier intended for generating input voltage transients to test DC->DC converters.
The README files the individual directories descibed above are a good place to start.
I would love to receive bug reports and user feedback. If you have improvements to the code, please get in touch.
