Turning anything into a touch sensor

Makey Makey is a small board with a USB plug and bunch of contact points for alligator clips. Plug the Makey into your computer and attach just about anything to the contacts, and you can make anything into a video game controller, a keyboard, a piano, or pretty much anything you can imagine. If [Sprite_tm] copied it, you know it has to be cool.

RepRaps will finally cost a million dollars

The Pentagon is throwing money at 3D printers. It’s “only” $60 Million the DoD is putting into 3d printer research, but hopefully our most brilliant researchers will help refine some of the ‘unsolved problems’ – like metal and circuit printing – the 3D printer community is facing.

Getting started with FPGAs

[Tim] found a neat little $40 FPGA board aimed right at the hobby hacker. The good news: It’s compatible with Arduino shields, and it’s very cheap. The bad news: it only has 1280 logic cells, so you probably won’t be emulating CPUs on this thing. If anyone has a teardown / project with this board, send it in.

Improving a Bluetooth dongle with a bit of wire

Unsurprisingly, the extremely cheap Bluetooth dongle [Mike] bought on eBay didn’t have great reception or range. No problem, because you can just replace the internal antenna with a piece of wire cut to length. Now bluetooth devices are recognized instantly, and there are no Bluetooth ‘dead spots’ around [Mike]‘s computer.

Come to France, make stuff
