So this is my question: based on experience, rather than theory, can anyone definitively say if duct tape wrapped around a PVC air chamber improves the safety of these devices? Please let us know in the comments. And if you shoot some video of your experiment, that would be totally sweet!
Summer is here, and I was looking for something to do with the kids. They raved about how much fun the rocket launching was at Maker Faire in San Mateo, and I wanted to bring a little bit of that fun home. All I needed to do was build my kids a kit version of Rick Schertle’s compressed air rocket launcher that was featured in MAKE Volume 15.
Jared Bouck is the driving force behind Sprout Board, an Arduino breakout board that lets you plug in a Duemilanove and a shield and provides a panel-mount set of screw terminals, all in a rack-mountable form factor. The prototype application for the SproutBoard is a DIY server room monitor that can be configured to provide remote temperature and humidity, motion, liquid water, smoke, room entry, and mains power monitoring. Local monitoring options include an LCD display and an audio alarm module. They’ll sell you the Sprout Board itself, in kit form, for $50, or a complete bare-bones server monitor with a fully assembled and tested Spout Board, an Arduino, an Ethernet Shield, a serial LCD display, a wall mount chassis, and a temperature/humidity sensor board for $250, which is about 1/5th the price of a comparable commercial system.
Designer Craighton Berman makes these cool lamps that are mostly formed from their own extension cords. Plus a laser-cut acrylic frame and a basic lamp kit. He’ll see you just the frame and the lamp, so you can roll your own, or a complete lamp pre-wound with a 100′ cord.
Laura Cesari, aka Chain of Being, makes beaded models of the solar system that, by the way, can also be worn as necklaces. Her work was recently featured on the blog of Carl Sagan’s Planetary Society:
Well, I finally get to let the cat out of the bag. We’ve got Pixel Qi screens available in the Maker Shed as of today.
Special Maker Faire version! Meet the PumLantern – a solar-charged, night-time activated light-pulsing lantern! This new pummer features even brighter LEDs than the old HexPummer, as well as stylized lantern construction
