Earlier this year, I wrote an article about how to use the Raspberry Pi to create a music light show using an open source project called LightShowPi. My little Christmas tree light show was popular enough that I was invited to demo it for a group of middle school kids in North Carolina.
Which brings me to this year's Christmas season. I was flirting with the idea of taking the light show outdoors, but due to the business of life I just ended up not having enough time (or motivation) to make that leap. I did, however, put a bit of time into improving last year's setup.
