I was searching for the device and I am unable to determine exactly which controller to purchase. I did help a friend work on a arduino for a underwater ROV, but my participation was limited. Any help you can provide would be greatly appreciated. I am a little, well, very new to the idea of working with a programmable microcontroller such as the ATtiny13.

More importantly, all this code is really doing is reading the ADC repeatedly then flashing an LED - this is a fairly straightforward task, and the difficult part is really amplifying the microphone to get a useful signal, which is done in hardware. Of course, everything is released under a creative commons license, so anyone is welcome to port it and tinker with it and improve it.

The last place I searched (should be the first) was in Google, using the keywords "hid lighting". Anyway, it was worth the search because I really like this website and your post regarding LED Fireflies in a Jar looks very interesting for me. Definitely Stumbled!

I really like your method for storing resistors as well, I may try something like that - a tiny tray for each one is way overkill, but putting them all together makes finding any one I want a complete pain.

Wires could easily be hid running down sticks and the LEDs themselves could be placed on leaves etc. that would look way better than just the wires. thanks for the suggestion! that’s a really really good idea!

I'm also considering 36SWG enamelled wire from Rapid but couldn't order any in time for this project (it's a birthday present). I may try again with some though, it would be an awful lot thinner. I'd really like to do them without the jar, too - have them around the room or outside or something. That’s a thought.
