This little gizmo has saved my bacon on many occasions.
Multirotors tend to fall out of the sky with no warning if you let your lipo go flat. I use strip LEDs as navigation aids to help orientation. The snag is they are very power hungry, one metre of LED strip draws about 0.5 amps, this takes a big chunk out of your flying time. To reduce power consumption I flash the LED's on a 1:10 duty cycle reducing the current consumption by 90%
The controller can handle upto 3 metres of LED's. It is powered off the main flight battery and monitors it's voltage. It can be set for 2-4S batteries. When the battery voltage drops to a preset level (3.3 volts per cell) the LED's flash fast to warn you to land. So, hopefully no more death dives.
I'm thinking of build some neat and tidy surface mount versions, I was wondering if anybody would be interested in buying them ?
