Using an old hard drive, some 1 watt LEDs, a complete redesign of the hard drive motor drive circuit and an Arduino Marcin Gosiewski (damago1) has built a great looking clock. The display is nice and compact since he is using a 3.5 inch hard drive as his base. “The project involves controlling HDD motor (3 wire brushless dc electric type BLDC) using open loop control without feedback, and using back
Alex Whiteway, Sungjoon Park and Rameez Qurashi built a great FPGA-Based Rubik’s Cube Solver. The system uses 3 robotic grippers to manipulate the cube, a camera to “see” what state the cube is in at the beginning and an Altera Nios II FPGA computes how to solve the cube. There are lots of algorithms available, the team looks at many of them and decided to roll their own solution. It isn’t
Yes you can purchase weather stations that are ready to go but where is the fun in that? The Raspberry Pi Weather Station is designed for people who like to take control of their technology.  “WeatherPi is a solar powered Raspberry Pi WiFi connected weather station designed for Makers by SwitchDoc Labs. This is a great system to build and tinker with. All of it is modifiable and all
If your computer keyboard looks a bit plain why not kick it up a notch? NeIdan built this Airship Captain MK-I – Steampunk Keyboard that was built around an every day keyboard and by spending a bit of time and a few extra pieces you get an amazing data entry device. “Tools used: scissors and x-acto knives also used heavy duty cutter for cutting the plastic keys screwdrivers Materials:
 These Internet Controlled Robots are not available to play with all the time but if you keep an eye on the Twitter channel you will have a chance to have a look and give them a try when they are online next. “I only put together one robot kit previously, then these two robots both started as Activity Bots. I hooked up a Raspberry Pi with an HD
What to do after you get your hands on a discarded scanning electron microscope. Ben Krasnow from Applied Science took the signal directly out of the device and fed it into a DSO. He was then able to capture it at a much higher resolution than is displayed on the original CRT that came with the unit. The results are incredible.
If you think the price of 3D printers is hitting the floor check out what Mikelllc built for $60. About 80% of this EWaste 3DPrinter is recycled computer parts which is abundant and readily available. “First of all, we learn how a generic CNC system works (by assembling and calibrating bearings, guides and threads) and then teach the machine to respond to g-code instructions. After that, we add a
