  • Starlino has a neat technique for making a cheap breakout board for lead-less QFN chips. In brief:

    • Drill a hole in a proto board so that the chip barely fits inside and has its connections on the same plane as the board. Fill gaps with epoxy or putty.
    • Tape over everything except one pad and and small path to the proto board.
    • Use a conductive ink pen to lay a path. Remove tape before the ink dries to keep from breaking the pathway when it hardens. Wait for it to dry and repeat on the other pads.

    The best part is that no hot air or breakout board is required.

  • Inspired by the Cylons from Battlestar Galactica, the tinyCylon has a row of LEDs that scan back and forth, glow on and off, and make other patterns.

  • shabadoo52 just posted a new project of his Bioloid robot doing some dance moves. He's looking for more ideas to make with the kit, so let him know if you have any. Shabadoo52 was the winner of our Bioloid Expert Kit giveaway contest.

  • There's a cool video of Ge Wang's laptop orchestra on apple's profiles page. They use pseudo-spherical speakers to give each laptop more of an instrumental acoustic presence.

  • The Roboduino is a Freeduino (Arduino software compatible) microcontroller board designed for robotics. All of its connections have neighboring power buses into which servos and sensors can easily be plugged. Additional headers for power and serial communication are also provided.Roboduino Kit page
