[Grenadier] wins the laser cutter for his portable X-ray project

The results of the Full Spectrum Laser contest over at Build Lounge have been announce. The top prize of a 40 watt deluxe laser cutter goes to [Grenadier] for the portable x-ray machine we saw at the beginning of the month. We think this is an excellent choice for top prize because, come on, this is pretty hard-core.

Taking second place was a Christmas light show choreographed to music. The open spaces of the University of Minnesota hosted the installation. We’ve embedded a video of the performance after the break.

Third prize went to the QC Co-lab Hackerspace for their light wall. It uses the ever popular GE Color Effects lights, with each bulb housed in a vacuum formed pyramid which acts as a diffuser.

There were also several honorable mentions. There’s a special place in our heart for [Jack Buffington's] solar clock which was included in this group. We think the use of fiber optics to pipe the sunlight into a machined index ring is ingenious. And you’ve got to give him credit for developing a project that uses no electricity and almost no moving parts (there is a slider to adjust for daylight savings time).

Buying, selling, and bartering hacking hardware

Regular reader [Grenadier] wrote in to let us know about his newly published hacking hardware trading post called The Junkbox. Apparently when he’s not blowing up capacitors or building his own high voltage ones, he makes time to code up a website where you can buy, sell, and barter leftover components.

We have something like this right here at Hackaday. The dollar sign icon along the right column, just underneath the featured posts banner will take you to our classifieds section which at the time of writing had a whopping nine items posts. But these things to ebb and flow. Check in on the newly posted link from time to time to see that number grow.

Whether it’s over at The Junkbox or in our classifieds section, we think the biggest problem is finding what you need when you need it. This is nothing new. If you missed it before, we’ve embedded an older episode of the EEVblog after the break where [Dave Jones] tours Apex Surplus. It’s as if a hacker who has hoarding tendencies bought a store forty years ago and just kept piling more and more merchandise to the sky.
