Yesterday I mentioned MIT’s soon-to-be-released open-courseware materials detailing a DIY phrased radar array radar system built from pegboard and wi-fi antennae. The project, from MIT engineers Drs. Bradley Perry, Jonathan Paul Kitchens, Patrick Bell, Jeffrey Herd, and Greg Charvat produces ‘radar video’ at about three frames per second. Greg just e-mailed me a link to […]

Cost of parts is about $950. The […]

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.
