I build things —in code and in the shop.
Senior software engineer by trade, maker by obsession. I design, print, machine and photograph — and write it all down.
On the bench
KaroKorry
An aviation-style illuminated push button, built from scratch: a tiny 18×18 mm board with its own brain, two RGB lights and a click, and any number of them chained together on just two wires.
Sango
An open source FreeCAD plugin for generative design. Give it a blank, the mounts and the loads. It finds where the part needs material and drops the rest, leaving shapes that look like bone.
CNC
A 3D-printed CNC machine built for precision — accurate enough to mill PCB boards, versatile enough for wood, sturdy enough for aluminum.
Latest writing
"I ran the first test and it's awesome"
Smaller screws, pins the printer could not print, a label, a clamp for the cable, and a jig that flashes a board on the first try.
No more soldering wires to every board
Designing a 3D-printed jig with spring pins to flash the buttons, and the simple question that changed the whole design: what stops the pins from falling through?
A reset that didn't really reset
A new way to make a button forget its address, a button that said it had forgotten but kept answering anyway, and a test sketch that was fooling me too.
The other end of the wire
A small ESP32 library so that using the buttons feels like "button 5, go amber" rather than register addresses and bytes.
Getting a whole panel to blink in step
Every button keeps its own time, and given a few minutes they all drift apart. One message that every button hears at once fixed it.
