Big projects for a small co-engineer.
I'm a dad who can't do anything the simple way. My son is four and has ideas. Together we turn his drawings into magic wands, plane-themed birthdays, RC bulldozers and whatever comes next — and write down how we did it.
Latest from the workbench

A four-year-old asked for a wand that does real magic. So we built one — with a microcontroller, a motion sensor and an unreasonable number of LEDs.

How a project happens
01
He dreams it
Every project starts as a drawing, a question, or a very specific demand. The kid is the client — and the creative director.
02
We build it
Crayons and cardboard meet microcontrollers, 3D printers and code. He gets real jobs; I handle the soldering iron.
03
We both learn
He learns how things work. I learn that the simplest solution was the right one, three revisions ago.
