Post latest mad scientist project (nixie clock)
I always wanted a nixie clock, and recently I've been building one. Here's a picture of the first ignition test:

Nice! I like how people are getting creative with a cheap raspberry pi. I used to do stuff like this on some of the parallax basic stamp boards, PIC microcontrollers, then eventually moved over to the AVR microcontrollers and boards. I might get back into it with a raspberry pi :)

The big advantage of working with Pi is that you can use a full linux stack (Raspbian is Debian) with a constantly updated distribution, or something else if you prefer. This clock already has the 'heartbleed' patch. If I actually ran CAT5 to this, I could use it as a wireless access point, but I just want it to tell me what time it is, and be really goshdarn sure about that time.

From the top: two high voltage DC-DC converters on the left, small audio amp, custom Pi power supply and expander PCB, Raspberry Pi (model B from UK), round blue 'Chronodot' RTC module, and three double custom tube drivers (BCD logic) along the front.

Damn that looks sweet! If you want accurate time, I guess you're gonna have to sync it with NTP servers - so you might as well add the whole network stack to it :P

Nice looking clock.

Did you use glass, lexan, or plexi for the clear stuff? Looks like glass, but can't tell.

Copper frame looks nice. Hard as heck to keep it all steady and square while you were doing it I bet.

Haven't played with Ras Pi, but can definitely think of cool applications for it. Just don't have the time to play with it.
