F-16 scratchbuild 68mm EDF styrofoam

I continue my research on F-16 lighting system by observing the real F-16 pictures....

[viper1990]

My canopy is getting messier with all the wires running everywhere! But after 4hours of soldiering my DIY circuit board and fixing up the LED lights... the F-16 lights up brilliantly against the dark background. I think now my F-16 is really ready for night flying

nice work.whats the damage?for the lights

[JieZ]

btw,your chart shows 2 LED.then how come on your F16 got more than it?ps.noob in electric circuits here.i like the tail whr the LED is shone onto the fin.How to position that way ar?

[viper1990]

Hi,

What do you mean "whats the damage" ?

The schematic diagram is only showing 2 Leds because thats just for the strobing effect (flashing) , The other lights aren't flashing therefore its not included in that flashing circuit so i've to design my own circuit for the rest of the lights (see picture for whole circuit).

Each LED have a specific viewing angle, some 15, 30, 45 degrees, If i'm not wrong my LED has a 30 degree viewing angle, large enough to cover up the F-16 tail . Just simple aim the LED at the F-16 vertical stab like how you aim a laser pointer at someone

Oh,it means the cost.
That means u have two circuits running?

[viper1990]

The cost is around $6, PCB board can get for $2 , Resistors,transistors, caps for a few cents, or free if you study electrical engineering in poly next year ,On the other hand, 0.5 - 1 watt LED came in prices like 80cents a piece. RED leds are cheaper while the blues are more expensive,probably because blue LED came into production in the early 1990s. Err..ok i'll stop here before i get carried away talking about LEDS

Anyway, The whole lighting circuit is counted as one circuit, esc is also counted as another , rx is also another circuit even servos have their very own circuit inside. So total i'll have 5 circuits ,ok i know its confusing. Just imagine everything inside the plane is one circuit and performs one job...thats is to make the F-16 fly with lights on

Oh..btw those are my LEDS.., i'm running low on them, need to stock up more I use to have plenty of em. accidentally blow them by pumping in 12volts directly accidentally.

nice job, what's the strobe speed like?

[viper1990]

Hi!, because the strobing pulse speed can be controlled by the var resistors onboard the circuit, i can have hundreds of combinations to control the strobing on and off from 0.05seconds to 30seconds per flash. Right now the default i'm using is flash (0.2s) off (1s). I'm not really sure this is the correct strobe timing but it's pretty much like that .

Heres a video of it strobing in action!

HI! Viper,

The strobe pulse speed is 4seconds per flash standard, the only thing is the two rear end lights........they only light up before & after took off the rest still same no change.

Alright thanks!, anyway if i'm not wrong there is a flashing red light too along with the flashing white light on every aircraft? Just like when i look up the sky i could see flashing red lights on commercial aircrafts.

Hey that's very nice!!! How do u make the Led's flash? I've got 1 set of Leds on my cessna in Post #24,http://www.daddyhobby.com/forum/show...t=32553&page=2, but thinking of making flashing green & red leds. How can I modify to make it flash?

[viper1990]

yo!

Heres a schematic circuit diagram i drawn for your cessna, Get a PCB board, few resistors of different resistance ,2 caps , 2 transistors and wires. The resistors preferbably can be replaced by a variable resisitors so you have more control over the pulse rate.

The voltage supply can be taken from one of your unused slot in the rx.

Feel free to ask more if theres any confusion.

[viper1990]

I can't stand the cuteness of this picture!! so kawaii!!!

Some kids i met at singapore poly stadium from sweden, they pose with my F-16 plane, especially this one i find it the cutest! he is taller then my plane by around 10cm

thanks, where to get those items?

N do i need to step down the current b4 going into the Leds from the RX? Coz my Led is for 2S while my cessna setup is 3S setting
