Recently, there was a great project on kickstarter to make a USB RGB LED. I missed it completely but thankfully my husband didn't, and recently a small package arrived containing _two_ of these lovely little blink(1) devices (very smart man, as clearly this was something I couldn't live without as soon as I saw it!).
I have used the blink(1) in a couple of toy projects (one using the datapoint API that I keep writing about but they don't show off its true prettiness, so I thought I'd share the command I use when I want pretty. The code is on GitHub and compiled on my linux system with no fuss.
sudo commandline/blink1-tool -t 3000 --random 2000
This produces something like:
It's hardly hardware hacking but it's certainly brightening up my office! Have you got a blink(1)? What will you do with yours?
