"I am 100% certain you can not run 12v strip with the outputs of the atmega 2560 at a hardware level (fry the chip). 5v will be the output but even still the milliamp rating on the 2560 is not high. You should use a switching transistor to drive the…"

"Graham, as you stated, blue light on the GPS indicated a fix, the red light should blink continuously unless you have armed the motors. the blue light next to the red light may be solid or flash depending on activity of the board.
You should be able…"

"Mike, can you please elaborate? I think what your pointing out is that at 100% duty cycle Tx will never cease to allow the module to stop and listen. How can I slow the telemetry stream to get below 100% duty cycle of the xbee?"

"My APM2 suddenly stopped working too from Output power rail. If I power it from the 5v/Gnd between the serial connection header pins, it powers up, though have not attempted to fly connected this way. USB power works fine. The only attached external…"

" I haven't tried it YET. But its the thought I'm running with. (found small air frame quads constructed like this)

I'm planning on using copper clad PCB for the entire airframe. Obviously etching off the copper to save weight, leaving it where I…"

"After some further research I'v decided to use the ATtiny85 microcontroller for each bank of LEDs.
I'v also order up some RGB strip from tayda electronics.  They're in a waterproof package, we'll see how heavy it is. I'm fairly confident that the…"
