Bluetoothing a Trash 80
Remember ye ol’ Radio Shack TRS-80 Model 100? I used one long after their heyday (when laptop really still meant luggable and battery life was a joke). This thing had wordpro, calendar, a term program, built-in modem, and it ran FOREVER on 4 AA batteries. Eric Gradman recently played a great prank on a new […]
Alpha (spoke) POV
Tristan Roddis of blog.cogapp.com writes: Following the great instructions from Evil Mad Scientist Laboratories, I built one, and then reprogrammed the chip to create a crude persistence of vision device, which could then be velcroed onto my spokes for use as a propaganda tool during the Critical Mass bike ride. Hardware hacking – the next […]
Two-motor quadcore BEAM walker
We’ve talked about bicore nervous net BEAM circuits in the pages of MAKE. This two motor walker uses four “neurons” in its brain and is therefore called a quadcore. It’s basically two linked, oscillating signals that create a four-legged walking gate over the two motors. Two photodiodes make the walker light-seeking (or.. um .. shadow […]
Preparing cocktail robots for roboexotica
Roboexotica gathers a wide variety of cocktail robot makers from around the world and bring them together for robot parties and presentations. I’m in Southern Austria in the city of Graz today visiting the information design college where a group of artists who are putting their cocktail robots together. The group shown above is in […]
Wavetable synth on an ATtiny45
A Make: Blog reader, garydion, posted this in response to my Making Arduino sing piece: On the topic of music on microprocessors, be sure to check out this site where a wavetable synthesizer is programmed into an Atmel ATtiny45. Amazing! I had to download the code and program a chip to confirm it really does […]
OLPC telepresence robot
Instructables hosted an iRobot Create competition a little while ago, and one of the third place winners was Damon Kohler’s OLPC Telepresence bot. It mashes two of my favorite consumer product designs into a cute mutant bot that’s controllable via a web interface. Rather than a huge electronics/robotics exercise, this project is fairly accessible to […]
