So if making a robot that can be remotely controlled wasn’t a tough enough challenge the guys over at Ufactory decided to make one that can roll around on a ball. Great looking design and it sounds like they are going to do a Kickstarter for it and release it as open source hardware to the community. I can’t wait to see a larger version that can be ridden
   Rohit Gupta needed a way to speed up PCB etching. Heating the etchant and agitating it are both well known ways of speeding up the process. If you are on a DIY budget this normally means you will be stuck sloshing the etchant back and forth for 10 minutes or so. Rohit developed the Open Agitator which uses a CD-ROM Drive Drawer to shake a tray back and forth. A
The raspberrywebserver.com is running on this Raspberry Pi Cluster Web Server. Visit the site to see all of the details so you can build your own. Steve figures that a 20 Raspberry Pi cluster would be equivalent to a PC server so it isn’t as powerful as a full blown server but it feels very fast and responsive when I tried it!

FozzTexx shows how he built a system that allows a Raspberry Pi to act as a Commodore 64 Disk Drive. His C-64 is tricked out with an Ethernet card so he shows us how he can pull a directory listing from the Raspberry Pi drive and loads an internet browser. It works but isn’t really usable for anything modern. The drive access is very slow due to the speed
Josh Kiepert built this Raspberry Pi Cluster while at the Electrical and Computer Engineering department at Boise State. He didn’t want to rely on the stability of the Beowulf cluster at the university while working on his doctoral research so he decided to build his own using 33 Raspberry Pi computers. He has stacked them wired them with a custom power interface so that he can keep the power lines
Chris Rybitski just shared his latest project with us, it’s a Stage Platform Robot. It is a way to remotely move stage items around. He built a 9 inch tall robot that can drive around with 900 pounds on its back. He built the majority of the metal frame from square tubing that has been welded together. There is an Arduino controlling the robotics and a speed controller that
Are you feeling the hype of Bitcoin yet? Instead of having a full blown computer mining your fortune in Bit Coins why not make solution that can fit in your pocket? The PiMiner Bitcoin Mining System uses USB miners that simply plug into USB ports on the Raspberry Pi. “Building this project will allow you to use a Raspberry Pi as a ‘headless’ controller and status monitor for your
