Wii+Physics Whiteboard What do you do if your regular whiteboard isn't going to cut it? What does it take to entice smart students to attend a recruiting tech talk? Well, a rear-projection, autocalibrating, physics-enabled whiteboard, of course. Vikas and Jeff prototyped this whiteboard in a tiny apartment in NYC, March 2008, demoed it at an HKN Tech Talk, recorded the "TechStars Tumbler," and promptly mothballed it for the hike from NYC to Boulder, CO.
FJCore Open source. Why does uploading photos suck? Well, it takes forever, and when it doesn't, you have to download and install yet another browser upload control. So Jeff studied libjpeg, as well as a handful of other JPEG libraries, and built the first Silverlight JPEG library in C#, FJCore. It supports a wide array of JPEG formats, so it should "just work" for anybody using it to accelerate JPEG uploads. EstateSales.net uses this library and a custom uploader (see video).
Blimpbots When Jason Dietrich announced that he wanted to build robotic blimps that could flock like birds, Jeff couldn't pass up the opportunity. So, Jeff, Jason, and Sam Wintermute spent an interdisciplinary, mildly insane, semester in early 2007 building and flying Blimpbots. The PCB design, microcontroller code, and computer vision tracking and control system are now freely available. Funded by GROCS 2007.
