Orhun Habib Erdogan
I make machines do things. Then I go skateboarding.
I’m Orhun. Mechatronics engineer from Eindhoven. I’m happiest where the code stops being code and something actually moves.
Dutch and Turkish, both native, which mostly means I can complain in two languages. I spent the last year on customer sites in the UK and India getting parcel sorters to behave. Before that: robot software, motor drivers written from register maps, a lot of ROS2.
Right now I’m between things, on purpose. The job ended in September and I’m not rushing into the next one. I want to work for myself, on stuff that’s actually interesting. Got a machine that doesn’t do what it should? Tell me about it.
The rest of the time I’m on a board. Skateboard most days, snowboard when there’s snow, surfboard when there’s a wave. Falling off all three, regularly.

asked me to build.
Scroll to put each one together. Every build starts as an exploded drawing, gets assembled part by part, measured, and then scanned into the real thing. Move the cursor to turn the drawing, hover the photo to see through it.Drag the drawing to turn it, press and hold the photo to see through it.

Out there.
Skateboard most days. Snowboard when there’s snow. Surf when there’s a wave and I’m near it. Plus a habit of booking trips that involve getting up at 3 a.m. to climb something.
Board 01 — skate. Most days, somewhere in Eindhoven. Here: the flat rail at the Trocadéro in Paris, Eiffel Tower in the background.
