LIVE AT THE FAIR — see the drawing machine run!

Hi! I'm Ewoud. I teach kids electronics.

I'm 15 and I build robots, drawing machines, and software for fun. At this booth: live demos, 3D prints you can buy, and hands-on electronics lessons for kids.

The stuff I built

Projects on display

● 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)

PCB DESIGN

Ducktop2

My second DIY laptop: a 16-inch x86 cyberdeck with a motherboard I designed myself in KiCad. Built around a LattePanda Mu with a direct eDP display connection and a low-profile mechanical keyboard — no dangling cables, no HDMI loop-back.

  • 16″ 2560×1600 display, Intel N305 compute
  • Custom 8-layer motherboard, designed in KiCad
  • 1,225 footprints on the board, hand-routed
  • Built-in RP2350 maker controller + radio hardware

RC TANK

Tonk

A fully 3D-printed RC tank I designed and built — tracks, wheels, and suspension bars all printed from my own STL files, driven by an Arduino with a motor shield. Independent track control, like the real thing.

  • 18-print frame, self-designed tracks & suspension
  • Arduino + motor shield control
  • Custom firmware (tonk_control_v2)

The part that matters

Tell me what you want to learn

Leave your details and I'll text or call you back after the fair. Takes 20 seconds — and if you're here with your kid, just point at the thing they liked and I'll find a class for it.

What sounds fun? (pick any)

Form acting up? It still saves your spot and I'll reach out — or just grab me at the booth.
