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
Al Williams from Hackaday has some nice tutorials to get you up to speed in using an FPGA. “Whatever tools you use, the workflow for any FPGA is basically the same, although details of the specific tools may vary. Sometimes the names vary a bit, too. Although you write code in Verilog, the FPGA has different blocks (not all vendors call them blocks) that have certain functions and methods they can
 Victor8o5 built this interesting 50,000V High Voltage Power Supply which is fun but can be dangerous if not given the respect that high voltages demand. If you are interesting in getting some serious spark jumping action this build is for you. Best of all the main component can be found for free from an old TV. “This high voltage power supply has been designed to output a fixed voltage of
The Dobot is an interesting robotic arm platform that has lots of cool uses. “The High Accuracy how easy for our M-1X to carry the small screwdrivers with full accurate strikes! Various Controlling Methods it could be controlled by via 6 ways including mouse, mobile APP, EEG, voice, leap motion and gestures. M-1X can read It support the VI system. Red or green? You decide! “
   If you have an IC with broken pins near the die normally this chip is dead but if you have a CO2 laser cutter and a bit of time you might be able to laser away some of the die so you can access the internal chip traces. Have a look at ca.rstenpresser.de for some ideas. “Since a few of the Pads already were delaminated I decided to
If you want to amp up your picture taking options a camera slider could be a great option. Purchasing one can be expensive so why not build your own. skepticaljay has built this one with a great list of required parts and a guide to make it.  “Parts: 1 10 foot 3/4 inch conduit ~1 foot of 3/4 inch schedule 40 pvc ~1 foot of 1 inch schedule 40 pvc
The prize this week is a HMC5883L Triple Axis Compass Magnetometer Sensor so you can add some directionality to your next project. This contest will run for one week (Aug 22 – Aug 28, 2015). Ending time is based on central standard time. To enter, identify the item above and what it can be used for. Please do not give the answer in the comments. Send an email to
