Reverse Geocache Briefcase Unlocks in the Right Spot
Check out Flickr user Rumtopf’s fancy take on the reverse geocache box. For those who don’t know, a reverse geocache is a box that unlocks itself when the GPS sensor inside senses that it’s in a specific spot on the globe. Rumtopf used a snazzy doorbell button to wake an Arduino, which checks the GPS and displays the distance from that spot on an LCD. He also used a magnetic child safety lock as a backdoor to access the inside of the briefcase in case of malfunction.
DIY Case for iPhone 4
Yes, you can cross-stitch your own artwork onto this nifty iPhone 4 case. What got me excited about it was that you could just as easily cross-stitch soft circuits on it with conductive thread. With a little extra effort you could barrow a little power and networking from the handset to give your project that extra kick. Or maybe you’ve always wanted a self-portrait done as a miniature latch hook rug. The possibilities are endless with this DIY case for iPhone 4 available from ThinkGeek.

New Early Release from O’Reilly: Making Things See (Kinect, Processing, and Arduino)
I’m proud to announce that my book, Making Things See: 3D Vision with Kinect, Processing, and Arduino, is now available from O’Reilly. You can buy the book through O’Reilly’s Early Release program here. The Early Release program lets us get the book out to you while O’Reilly’s still editing and designing it and I’m still finishing up the last chapters. If you buy it now, you’ll get the preface and the first two chapters immediately and then you’ll be notified as additional chapters are finished and you’ll be able to download them for free until you have the final book. This way you get the immediate access to the book and I get your early feedback to help me find mistakes and improve it before final publication.
