Brushless gimbal almost complete
With the arrival of the Mobius action camera, which is a Full HD (1920x1080 @ 30 Hz) little animal (very nice video quality for the price), my aerial filming addition to my #1 quadcopter is almost complete. The only missing element is the gimbal controller board, which I have ordered through ebay, but my mistake (or not) the seller have sent the MPU6050 instead (which I had at the same time ordered from a different seller). Result: I have two MPU6050 gimbal sensors and no gimbal controller. As such a dispute is being solved, and the seller decided to (supposedly) ship me the controller board. Otherwise I will escalate to ebay, get refunded, and the seller downgraded (or banned, who knows..).

Improved quadcopter - more "avionics" and increased run time
In the several weeks that followed a crash caused by an ESC failure, plenty of work have taken place (some of which documented here). Several things have been done since:
- Replacement of the ESCs with a 30 Amp quad ESC;
- Upgrade of the flight controller firmware;
- Building and programming the PPM Sum encoder;
- Building a BEC/filter with 12 V and 5 V outputs;
- Adding landing gear;
- Adding voltage and current sensor;
- OSD firmware upgrade;
- Change of LiPO battery from 11.1 V (3S) to 14.8 V (4S);

Induction Stove
Some days ago my father asked me to check if I could repair this single element induction stove. I disassembled the device to inspect its inner workings. I was a bit curious because I have never taken apart this kind of apparatus.
