First test, 6 RED LED at 20mA hi power types from SHARP
Sec test, before mounting head-lights :-)
I am really thrilled about the light output.
A total of 20 LED's was used
6 Red, 6 Green, 4 White pointing front 2 on each side, 2 Blue pointing back top side, and 2 orange pointing back bottom side.
Using the 8-9Volts from the 8 cells, and 100 Ohm series resistor, and 3 LED in series.
The blue LED's are 3V types, and the Orange are 2V types, so in this case 150 Ohm was uses.
The White LED's are also 3V types, so then I just use 2 in series, and 100 Ohm.
All wires are 0.2mm copper isolated, thin and light weight and easy to route.
the wing half where the antenna is located, I have added ferite breads and 2 windings
else the suppy wires for the LED's will act as an antenna in parallel with the real antenna,
This would ruin the range, if no ferite was used.
There was a spare channel available, so why not add a PWM regulator ??
This is the smallest 10A PWM regulator I have seen so far :-)
All my LED's draw about 175mA at 8V
The HUGE IC is the PIC12C508 and the small one a 10A FET in SO8
PIN 1, 2, 3 are +5 from RX, pin 4 is PPM input from RX, pin 5 FET GATE, pin 6-7 cut away, pin 8 GND from RX
The little SMD capacitor is 100nF
for safety I have added a reverse diode over the output
Zoomed out, you see the wires going left and right and over the edge to the bottom LED
Zoomed even futher out, you see this wing is really old and crap,
but since I dont know how dificult night flying will be, I think using old crap first is smart
Left side with the antenna, and the 3 small ferite toroids
Make 2 windings or even 3, make little hole, press in, then use thin transparent tape
More closeups of wires, it was really fast and easy to add this LED light modification
LED at the center of a winglet, to keep good arodynamics and best viewing angle,
I have made the cut like this, and again used transparent thin tape
At the back edge, pointing back
Out testing at night
