Most of the Maker Faire attendees have spent weeks or months putting together their projects. [Matt] is doing things a little differently. He brought two thousand boards, each containing twelve pentagon PCBs with individually addressable LEDs mounted in the center. This weekend, he, his team, and anyone else who can wield a soldering iron will be assembling these pentagon panels into a gigantic glowing crystal.
Last year, [Matt] put together a Kickstarter for Blinkytape, a WS2812 LED strip with an Arduino on one end of the strip to generate patterns of colors. This year, [Matt] is moving into three dimensions with a system of pentagons with a single RGB LED mounted in the center. The pentagons can be soldered together into a regular polyhedra or a convoluted wall of LEDs that form a geometric crystal pattern of blinkyness. The Kickstarter for the BlinkyTile should be up before the faire is over.
[Matt] has a few tips for anyone wanting to run their own Kickstarter: don’t have a lot of SKUs. [Matt] only has to keep track of a single panel of twelve pentagons. Compare this to other failed Kickstarters with dozens of options, several colors, and a few stretch goals, and you quickly see why many, many Kickstarters fail. [Matt] is just selling one thing.
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
The Toulouse Hackerspace is having a little shindig this coming weekend (May 25-27) featuring a conference, workshop, concerts and performances. If you’re in the area, drop on by,
