Core77 has a short post on The Hoffman Dovetail Key, what appears to be a simple, elegant and compact system for dovetailing wood parts together.

For those not grasping it right away, this system can enable an absolutely radical change in your production system. Consider that items joined with these HD Keys require no glue, no glue-up, no cleaning up the squeeze-out, no clamps, no drying time. Finished pieces can be stacked as soon as they’re together with no worries about glue squeeze-out from one piece marring the one beneath it, obviating the need for racks.

I’ve been saying “biscuit joiner” when people ask me what my favorite tool is (they do ask, I don’t know why). I might have to change my answer now.

Regenerative braking for bicycles and more. Intelligent power boost while you pedal, Wifi connection, API for developers… This is pretty great stuff, but now someone has to figure out a bulletproof way to lock your rear wheel.

Microphone system maps rooms with a snap of the fingers.

This is interesting. They were able to find a wall with 1mm accuracy. Less successful in a complex room (a cathedral nave), but still–that’s fantastic.

Compare: 3d mapping by ZCorp ZScanner, Trimble, MatterPort, and of course, Kinect.

Next up: 3d mapping by smell.

Another major breakthrough in light fixture technology: ultra-thin OLED. Some nice designs at Blackbody, but I think it can go much further.

Microsoft IllumiRoom is a coffee table projector designed for the next-generation Xbox | The Verge.

Still in R&D phase, but impressive. A Kinect maps your living room then a projector extends the video area of the game you’re playing. Nauseatingly immersive.

Cute. They should make another one with a propeller, might get more juice out of it, especially in a high-rise.
