● LIVE DEMO
Drawbot
A half-meter-square drawing machine I designed from scratch to be
as fast and cheap as possible. CoreXY belts move the pen across the
paper while a scotch-yoke mechanism lifts it between strokes.
Watch it draw live at the booth.
- 0.5 m × 0.5 m drawing area
- CoreXY belt design, NEMA17 steppers
- Arduino Uno brain, custom code
- Built for Hack Club Highway

ROBOT
Tarmo5
A fully 3D-printed, open-source robot car. I printed the chassis,
wired the electronics, and got it driving — then made it mine.
It's the project that turned me into a maker.
- Entirely 3D-printed frame
- Custom electronics + remote control
- Open-source build (Building Tarmo)

MAKER RADIO
Foxhunt
Spy-gadget hide and seek. Hide the "fox" beacon somewhere in the
house, then walk around with the hunter — it beeps faster and
flashes RSSI on an OLED screen as you get closer. Real amateur
radio fox hunting, on cheap 2.4 GHz modules.
- ESP32 + nRF24L01+ radio link
- OLED signal-strength display
- Beeps faster the closer you get

Graphing Calculator OS
An operating system I wrote from scratch — no Linux, no Windows,
just hardware. Type an equation and it boots straight into a
graphing calculator with animated plotting and implicit curves.
- Handles keyboard, mouse, and plotting
- Up to 6 equations at once, color coded
- Supports implicit equations (circles!)
