Hurrah! The laser cut acrylic for my NIXIE tube clock casearrived this morning, and amazingly all the parts fit together nicely. The screw holes even matched up with the PCBs!
I'm pretty happy with how this turned out, and I can finally say the nixie clock project is ...

Everyone has to make a nixie clock at some time, and as I had 12 IN-14 type tubes lying around for quite a while after ordering them from Russia ...

I've been trying to make electronic fireflies for ages now, and most of my previous attempts involved RGB LEDs, and one of them per ATtiny13 with code to flash a random colour now and again. This was always going to be a pretty expensive method, but after seeing http ...

This device analyses the music it picks up via the electret microphone, then flashes the LEDs in time to the music. It's encased in the box SparkFun sent me the microphones in, since the box was just begging to be used as a ...

At the same time I etched the LED Firefly prototypes, I did some breadboard ICSP adapters. I've been working with ATtiny13s a lot recently, and they are a pain to program while breadboarding, so these seemed like just the thing.
It has a 6pin ICSP plug on top, and ...

It could scroll any text I wanted, specified as a char array in the code. I had it working fairly well and decided to make a PCB for it...
