Hacking IKEA LEDBERG flexible rgb lightstrip

I got a roll of awesome rgb lights at IKEA and used part of it to make an infinity mirror (sorry the link is to IKEA Europe but for some reason it's not on the US site, but anyway it was here in large quantities in Brooklyn). It's made to cut at certain points marked with a scissors and I only used a few feet of a 5 meter roll for the mirror project. So at the time I thought I would figure out eventually how to use the rest. It would be a shame to throw away.

Milling PCBs: Fritzing, FlatCAM, and Carvey

I have a new superpower of making PCBs! Here are my steps, worked out over several boards of my own and my students. The project here is one my students did using an Adafruit Pro-Trinket 5V to program 5 LEDs and a button. (I now know we could have used an ATtiny84 to control the LEDs but I'm just starting to learn how to use them.) Here are a few finished projects.
