Electronics, built from the ground up.
I design and build my own tools and instruments: a handheld multi-function test probe, a discrete-logic 8-bit computer built one gate at a time, and a small line of DIY guitar effects pedals. This is the build log.
What I'm building
Three projects, all feeding into each other — the computer build needs a probe, the probe needed a computer to debug.
Diagno
A pocket-sized, RP2040-based handheld with four reconfigurable test probes — DMM, logic probe, bus probe, signal generator and more, all in one device.

AGR Microcontroller
A Ben Eater-inspired 8-bit computer, built from the ground up: transistors → logic gates → latches and counters → a full working system.

Guitar Effects
Hand-built pedals — reverb, chorus, fuzz, distortion, and noise gate — designed and assembled from scratch.

The 8-bit computer build in particular has run on parts and PCBs from these sponsors — see the full story on the build page.
