I needed to pick up some fairy lights for a project, so off to the thrift shop!
A child of the hyper-consumerist 80s and 90s, Matt grew up on a steady diet of sugared cereal and UHF television. As such, his sense of nostalgia is driven as much by advertising trends of the era as it is by music or other sociological elements. This leads to an interesting relationship with the winter holiday season, where seasonally-themed television commercials hold as high a place in tradition as any carol, tree, or gift exchange. To celebrate this odd bit of seasonal nostalgia, Matt builds a retro-television-themed ornament from a Raspberry Pi that plays those magical commercials from his youth and is powered by a strand of holiday fairy lights!

As part of Project Rankin, I need to be able to convert 120VAC to a more usable 5VDC, so I’ll be using a ubiquitous wall wart. However, I want to keep it as clean and tidy as possible, so I need to wire the adapter directly into the project itself. While I’ve got the case off, I’ll walk through the basic components and how an AC adapter works.
For Project Rankin to come alive, I needed it to have some level of audio, but I didn’t want to plug some USB solution in or even use the on-board mini jack if I could help it, so I figured out a quick hack to get sound from the Raspberry Pi A+ out to a simple speaker.
