Forget about machines that can replicate themselves, what we want is a machine capable of making an 8 inch wide hollow torus out of sugar. The CandyFab project has been around for a while, but with the release of the new machine, the CandyFab 6000 they are reinventing the project. Built from the ground up to be a candy constructing beast, the CandyFab 6000 might be a little smaller than the previous version, but it’s much better designed. You can get more details on the new wiki site.

Ok, there aren’t any usefull applications we can think of for this one, but we want one really badly. This is a combination of a miniPOV, some UV LEDs, a CNC rig, and some glow in the dark paper. The Ghost matrix works similar to a dot matrix printer where it flashes the UV light to activate the paper. The final effect is very nice. Great job on this one.

Purple Crayon is a new entry into the home fabricating arena. Shown above, with it’s makers [Konrad] and [Aaron], it’s set to compete with RepRap and Cupcake. It looks to be bigger than Cupcake, but smaller than the reprap. There aren’t many details available on their site, but we’re sure there will be soon. They do state that it should retail for less than $1,000.
We’ve seen a lot of 3d printing lately, with the RepRap and Cupcake, both the fused deposition modeling type. We don’t often see the Inkjet method. This is a great example of one, built in someones home. Instead of laying down layers of molten plastic, he uses the inkjet system to deposit glue like substances into layers of plaster. This project is much higher resolution than the other two, as you can see in the video of it making an RC engine case below. He is currently rebuilding it to be even better and larger.

[Jed] from Toronto’s hackerspace HackLab.TO coded the theme from Super Mario Bros. for their laser cutter. He’s posted the ruby code that generates the g-code from a simple tablature.

[Murray484] submitted his instructable on how to create a stepper motor controller from an old scanner. He removed the motor and controller from an old scanner then harvested the parts. He’s pretty much starting over, taking the ULN2003 chip from the scanner motor controller and putting it on a fresh board. He then wired it all up, installed the software and got it working. Finally, he built a container out of cardboard for it all. Though he could have made it nicer looking and used higher quality building materials, he was trying to make this a “green” project for the epilog laser cutter contest. He’s done a good job recycling, this could be pretty useful.

With some careful programming and probably tedious testing, [Tim] was able to get his CNC router to play [Jonathan Coulton’s] “Still Alive”. He didn’t just tell the motors to spin at the correct speeds directly though. He computed the 3d vectors necessary to produce the notes. The router thinks it is just doing its job. We would love to see those vectors rendered out in 3d space. Imagine having a physical sculpture of “Still Alive” as seen by a CNC machine. This reminds us of the Obsolete Technology Band.
