Our latest Weekend Project will launch not one, not two, but ten model rockets simultaneously! Built around a 555 Timer IC and a few different types of launch switches, this project is ideal for rocket clubs and launch events.

Weekend Projects is back! This year we’ll be making more with LEDs (but of course!), lasers, and solar power; we’ll be building bots, rovers, and bending circuits, among other projects. And for our first build – Game Show Buttons – we’ll be using the versatile and legendary 555 timer.
Remember, just because Weekend Projects is on break at the moment, that doesn’t mean you can’t send us your stories and pictures of your mods! Belfast-based hacker David writes in with this awesome upcycled Light Theremin…
During the course of Weekend Projects there were several projects that I was personally excited about, to both tinker with and write about. But there was one obvious crowd favorite among the fifteen beginner projects we built. While there was no competition per se, the Light Theremin was the obvious winner.
Going back through my Weekend Projects notes, I realized I never got around to properly thanking Mike and his daughter Jessica who brought their patriotic tri-color mod of the Floating Glow Display to World Maker Faire in September.
Looking for a very last-minute handmade present? One of our readers, Mark Hache, just made this floating glow display for his wife (and tweeted it), using the instructions from our Weekend Projects series.
