This is a prof of concept for a simple gimbal stabilizer with a Micro:bit board and two servos. It won’t hold any heavy stuff like mobile phone, HD cameras, etc, but some simple camera small should be fine.
Be careful with the servos, better with metal gear (“MG”), but the consume more. 4 x 1.5 V AA batteries or 5 x 1.2 V AA batteries (6 VDC) should be enough, but don’t expect a very smooth work, as servos usually requiere quite enough current. Ni-Cd or Li-ion batteries are better (see more comments in my Instructable, linked below).
Some adjustments can be made by software in my code, specially:
- Offset: if the main arm or the stable platform are not perfectly aligned, you can move a bit each servo’s leaver, but a finer way is with the x and z offsets that are included in the software.
- You can test the level by pressing the A button.
