We created this image to show the someday, incandescent lighting may be extinct, since LEDs use less energy and last longer and are better for the environment. So we used the world's lightbulbs for fun things like windchimes, wine bottle stoppers, and bobbers for fishing.

Seen Here: The PCB with chips and resistors etc all done.
So, today my PCB for the LED matrix arrived from BatchPCB! For what I paid, the PCB arrived fairly quickly - I ordered it on the 15/02 I believe, and it arrived 11/03 -- 26 days, which is pretty good (they state 19 business days).
The quality is very, very impressive - far better than anything I could pull off at home. The silkscreen and soldermask makes it look really nice, too.
Soldering it was a joy, although there was a LOT to solder and it's all surface mounted.
I had a few problems at first; it wasn't lighting the matrix at all properly but I soon realised with my new design (transistors on the cathodes) I have to write the transistors HIGH to get a LOW on the cathode, so a quick line of code changed to get that working.
Then for some reason the top half of every letter was flipped. It turns out this was my fault: I messed up when making the package for the LED matrix in Eagle, swapping the matrix's 5th cathode for my system's 8th, 6th for 7th, 7th for 6th and 8th for 5th. This was fairly easy to fix in code, however.
Finally USB isn't working to program or communicate, but I can configure the FT232RL chip (after all, it's sending the clock pulse that's driving my ATmega168). I think I have an idea of what's causing this, but I'm not sure yet.

Not so much a picture of LEDs - you can still just about make out the shape with some wishful thinking, more a picture from the innards of my lens.
LEDscape driving LED strips in a aluminum extrusion channel with diffusers. An art piece by Matt Mets, on display at NYC Resistor.
The bargraph sequences up and down with a different mode when "firing". The switches to the left of it control the lights in the pack and the gun.
More work required - diffusers?

Discoteca illuminata interamente a Led. L'intera gestione dei corpi illuminanti ( pilastri, pavimento, lampadario, banchi bar..) è affidata a un sistema DMX.
Dal banco regia è possibile gestire i singoli elementi o tutto l'insieme in modalità Live o richiamando le scenografie precedentemete programmate.
First candidate LED donor: Sigma Micro. Small, and costs less than $10. Better yet, I had one languishing in my workshop.
