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.

Smoke test after a lot of changes

It's always a stressful moment when after many changes something is put to the test. This was the case, taking into account that since the last flight there was a replacement of all ESCs, upgrade to Arducopter MPNG 3.0.1 R4, installation of PPM Sum module, addition of voltage and current measurement, and use of a higher system voltage (4S instead of 3S LiPo).
