This project was started in , electronics and control loops. Because I always need a cool project to learn new things, it was clear that something that can fly had to be built.
The project started as a "tricopter-only" project, but as I wanted to build smaller vehicles with more payload capacity, I decided to make some quadrotor, hexacopter and Y6 hexacopter firmwares too. My main interest is to build very small MAVs that fly as good as larger ones (or even better) and that can be controlled by wireless video link. I also experimented with autonomous flight in GPS-denied areas (video), and with GPS assisted autonomous hover (video).

GEMïNï progress...

I just realized, that I haven't yet posted an image of the PCB that I am using since half a year in the BOLT S|2 and soon in the GEMiNi. It is really small and weighs around 1 gram. It contains the minimum number of parts possible + 3 LEDs:
Thermoforming the canopy also worked pretty well once I found the correct temperature. I tried Vivak (PET-G) and black Polystyrol:

The chassis should be finished very soon, I am really looking forward to putting everything together...!


  1. Sieht echt mal wieder super aus! Wie machst du eigentlich deine Platinen?

    1. Hi Stefan, die Platinen werden in Eagle designed und ich lasse sie bei bilex-lp fertigen. Das Löten (die ICs haben keine Beinchen) geht einfacher als gedacht mit nem normalen Lötkolben.

    2. Danke für die schnelle Antwort. Wenn ich das Geld hätte, wären meine Copter auch so klein :)

    3. ich glaube das hat weniger mit Geld zu tun, sondern mehr mit der Zahl investierter Arbeitsstunden für die Entwicklung... ;-D

    4. Ach das wär kein Problem :D Hab fast einen Tag an Arbeitsstunden nur an meinem Aeroduino gesessen ;)
