Builder

Just always loved building things.

Autonomous car from above — servos, wiring, ultrasonic sensors

From soldering irons
to space hardware.

~2015–2016

The beginnings

Around fourteen I got my hands on an Arduino and a soldering iron. No tutorials, no plan. Just a desk full of breadboards, relay modules, ultrasonic sensors, and wires that went to places they probably shouldn’t have. Most of it didn’t work. Then slowly, some of it did.

The projects

Racing Drone

Carbon frame, brushless motors, Taranis controller. Soldered every connection, flashed the flight controller, crashed it on the first flight. Rebuilt it. Crashed it again.

Autonomous Car

Raspberry Pi + Arduino + a cheap RC chassis. Ultrasonic sensors on every corner, a camera up top for lane detection. Stitched together from forums, datasheets, and stubbornness. It drove itself. Sometimes even in the right direction.

Cocktail Machine

Raspberry Pi controlling peristaltic pumps. Select a drink, watch it pour. Suddenly everyone wanted to visit.

Rocket Launcher

Bluetooth-controlled firework launcher with electric igniters. Built a wooden rack, wired each rocket individually, controlled the whole thing from a phone. One went off in the garage. Accidentally. Nobody was hurt, but the ceiling remembers.

3D Printing

MakerBot Replicator. Printed everything from a Death Star to a Linux penguin to an Einstein bust. Also a hexapod spider robot. And a “hacker inside” sticker for the laptop, obviously.

For the family

Not all building is for yourself. Ran Cat7 cables through every floor of the family house, set up a server rack, terminated patch panels. My grandpa built the house. I gave it 21st century internet.
