Plane survived without a scratch
Short compilation of a Blunt Nose Knurrus Maximus flight after fiddling with the CG. Still not perfect
To record my FPV videos I bought such 2.5″ DVR recorder on eBay:
There are no buttons on the recorder. All controls are done using the IR remote control. Dealing with the remote isn’t very handy out in the field, so I decided to add three extra buttons for record, stop and preview:
Very simple: An AVR ATtiny25 generates the IR commands which are injected right after the IR receiver. All you need is just 3 push buttons, an ATtiny25 and one 1 KOHmresistor.
The ATtiny25 needs run on the internal RC oscillator with 8MHz, so fuses needs to be configured the right way.
Download the schematic and firmware:
By the way, how my ground station looks right now:
The new 28 channel receiver combined with the modified 2.5″ DVR. Everything is powered by a 3S LiPo battery.
