I'm totally new to this sorta thing

I can see anything showing exactly where to solder the feed from the Stock LED

What board is needed exactly

Can I use some strip leds than a ring

I'm in the UK so everything is to be off eBay
Hi. You need;
1. Small Arduino or compatible board; the Mini, the Nano, Digistump, Trinket. Has to be 5v though, watch out some are 3.3v.
2. Some Ws2182b or similar RBG addressible LEDs (not very cheap, I can't find anything cheap in the UK. I got mine from Coolcomponents.
3. A 5v 2A BEC. These things are going to current, and can draw a bit depending on how many you have, so don't run off your flight controller power.
4. 10v 1000uF capacitor. This protects the delicate LEDs from dirty power.
5. A 300 ohm resistor. Something about protecting the data line. Some don't use it, but blow up the first few LEDs, so just stick it in there.

My attempt blew in the first 5 mins of using it. Something went wrong and the Naza Lite started flashing all its LEDS, and when I unplugged the Arduino all was well again. I think I've going to use DIODES on my LED feeds to make sure the arduino can't send anything BACK to the Naza.

But First things first; go over to
and have a good read, then you can start messing with the WS2812b LEDs. Nearly every clone of the arduino is different, so PIN numbers can be consfusing, especially when PIN 1 on the board is called something else for some reason.
Once you are happy with the Arudino and the LEDs, you can attempt this post.

Take a splice from the LEDs for the Naza, I used old servo extension cables to take the feed from LED and split it, giving you cables going to the Naza, and some you can take to the Arduino.
Upload the code from the first post, paying attention to modify it for the LED type, and the PIN numbers for the WS2812b and the feed from the Naza. Some boards need to be told which pins are in , and which are out. I think mine had a fit.

I'm going to be working on mine again soon; my quad never really got off the ground last year, I'm going to rebuild and try again. Should have just bought a phantom...
I'm in the UK too, so we can always chat off board to get this project of yours going.

heres some i used , I 3d printed tri mounts for mine

theres rings too

I like the banggood version too

Strips of WS2812b

Digispark Mini board

Arduino Nano

I'd say get yourself a full size Arduino or at least a Nano to have a tinker with them to familiarise yourself. The software is not so friendly for arduino, I had to mess around for ages to get newer versions of find my attached board.

I'm waiting for my under motor mounted LEDs from Banggood.

This is a completely awesome thread. Just curious to know if the sketch for the Trinket work with the Teensy 3.2?

Thanks in advance. Pat

Why not use an ATTiny85 directly?

If I'm not mistaken Trinket and Digispark boards basically add the USB interface which really is not of much use after the microcontroller has the cod and The ATTiny85 code can be uploaded from another board such as an Arduino UNO or probably any other board acting as ISP.

The form factor would be slightlly smaller, weight slightly lower and, although it makes no change at all on flight time, power consumption would be lower as there would be no LED on the board.... and probablly cheaper.

A bit of digging out but I'll try anyway - is there a ready made code for a quadrocopter? I'd like to use this setup for my F450. I am capable of soldering and doing all the mechanical/electronical stuff but have no idea about programming and would like to have a fool-proof software to put into arduino. I believe all that needs to be done is to copy/duplicate the code for the single rear ring, but still - too afraid to make it myself.

I've been struggling a bit here. I can't get the arduino to mirror the led from the Naza. I've tried different sketches but I'm stuck. Could I get some advice?

I managed to get it working by trial and error on one of the codes. The key was to lower from 500 to 400 the values for detecting the original naza led signal. At 500 it detected only one colour, at 40 0 it started working.
