Project White Star, those intrepid souls trying to fly a weather balloon across the Atlantic, built an excellent helical antenna to be featured as part of their next payload. (The one pictured above is not their final antenna, but one of the experimental ones.) After the scrub on the launch pad for flight attempt A, […]
Image courtesy fabfolk For about $60 in materials and a little elbow grease you, too, could set up your very own FabFi metropolitan area network node. What’s the catch? You’ll have to build it yourself. Fear not, because everything you ever wanted to know about setting one up is available on their wiki. Starting as […]
We have covered Alan’s Biocca’s fantastic clearinghouse site antennalaunchers.com before, and Brookfield, CT, resident Andrew Stoev’s basic launcher design appears to be a slightly up-gunned version of Alan’s CSV19 pneumatic antenna launcher. It’s a beautiful build, but my favorite feature is the quick-release mount he added for his Android device. Using a free app called GeoCam, his phone, when so mounted, becomes an augmented-reality aiming scope that provides GPS location, compass orientation, and (probably most usefully for this purpose) phone inclination data.
The diabolical “Can Bot” from YouTuber longjie0723 will wait until you’ve had one too many, then, at just the right moment…ATTACK!
If you’re looking for more control than the average shutter release cable, then you should check out this DIY Bluetooth shutter release from YouTuber Scott Wallace. Using an Arduino Uno, BlueSmirf Bluetooth transceiver, and some perfboard, Scott fashioned a device capable of accepting commands over the air from his Android handset. [via nikonrumors] The camera […]
Beth’s prototype design, here, uses 100 turns of AWG 40 magnet wire, an ATtiny85 integrated circuit, a couple of surface-mount capacitors, and a duct-tape substrate sealed under a layer of clear packing tape. She reports that “the read range is practically indistinguishable from a mass-produced RFID card.”
Here’s the next step in the Blendophone project I’m building for Maker Faire: making it wireless. (Note: I’ll be doing a talk about the Blendophone with my co-conspirator, Usman Muzaffar, at next weekend’s Maker Faire Bay Area 2011 each day at 3pm on the Make: Live stage in Expo Hall). So far, I can control […]
