See <a href="http://sfe.io/9825" rel="nofollow">Pocket AVR Programmer</a> for more information (be sure to read the comments as well).</p>

The flicker rate on this is way too high, and there's no color fading. Not very candle-like, really. It does appear that it's reprogrammable. I'm going to attempt to reprogram it using an Ard Nano as an in-system programmer and see if the result is any more useful, I hope that it is, otherwise I'll be feeling pretty gypped.</p>

Second for a Great! I took the plain LEDs and replaced them, with 0805 SMT LEDs in red, amber and yellow (630, 610 and 590 nm wavelengths, 10 - 20 ma rating) soldered on 32 gauge wire about 2 feet long. Caution, green LEDs can be a problem for 3 volts, blue is out of the question. I only go up to yellow green (574nm) but red yellow amber works out better visually too. Now I have a cloud of lights (well, 9 anyway), each light the size of a grain of rice! My wife loves it. I had to make another for her. Soldering SMT on magnet wire can be tricky. Tin the wire first. I use clear nail polish on the LEDs to make sure it does not short out in case it some in contact with metal. Batteries (fresh AAs) last over a week. In this case the random light changes makes for a better effect.</p>

An electric candle which is RGB, random colors, and no button to toggle modes? You can already get candle flasher LEDs which proudly flaunt unnatural candle flicker and color.<p>A candle kit is an IDEAL ATtiny tutorial platform, but it looks like the only concept this can offer is soldering.</p></p>

Measured my batteries and they were only putting out about 2.2V. Hooked up a 3 volt power supply and now it works great with all 3 colors and nice brightness. Definitely get fresh batteries.</p>

Second increase your vcc, on mine the blue was not working so I went to 3 batts and everything worked great</p>

I see you've two spare pins on the micro - 5 and 6. If the blue LED channel was driven from pin 6 instead of 7, you'd have 5 and 7 free, which would enable I2C communication with the board (and these pins are ever so conveniently broken out for you already, right in the middle of the ISP header). A little custom code and you'd have a nice little I2C controllable blinky.</p>

I do not have the green led's working at all on either kit. Have not finished troubleshooting so don't know if I screwed something up or if there is something else going on. The default software really is useless... The only code changes I needed were the pin assignments (The green LED's did not work before I reprogrammed...) and the interrupt enable is "TIMSK =" not "TIMSK0 ="</p>

I just put one together and it certainly doesn't emulate a candle (lol, not that I expected it too) but I did expect color fading and there is none. It runs amok. Looks like I am going to have to solder headers on one of them and bust out the C code. I will try Paul B's code with some tweaking. Fortunately I am using them for soldering practice. I did buy 60 Tiny Cylons too but could not get 75 at the time so I bout 15 of these. Keep ya posted. but this isn't high on my to do list...</p>

Maybe like this one http://www.enjoylighting.com/lantern.htm<br>
Then I read RGB and I thought cool a kit that fades though the rainbow of colors.<br>
But when I tested the code, it seams to just strobe all leds at an epileptic rate... ???<br>
:(</p>

Also, it looks like the LEDs only cycle each LED colour on and off with a 400ms delay. Seems a waste not to cycle through, well, more colours.<br>
I just made an RGB nightlight for my kids which goes through a few million colours. You could steal my source code and apply it to this kit if you want. I used an ATtiny13 and common anode RGB LEDs so the code wouldn't need that much tweaking:<br>
