Lovely Radial LED Matrix
Beautiful work from Instructables user ledartist. “Aurora” sports 162 RGB LEDs on a custom two-sided PCB and a fancy high-resolution PWM scheme to provide impressively smooth color transitions. Mesmerizing.

FireBot, an Extinguisher-Wielding Robot
MAKE perennial Steve Norris of Norris Labs built this fire fighting robot. I couldn’t find any deets on Steve’s site but it looks cool!
Muze, an Arduino Music Maker with Evolving Melodies
Joshua Maruska and Adam Kumpf from Teague Labs created an interesting Arduino-based musical instrument called Muze, which synthesizes evolving melodies. According to their site, they’ve “educated Muze with a palette of notes that it can in-turn interpret and compose into various rhythms and phrases that are strung together to form something musical.” The user is […]
Toolbox Review: iMSO-104 Oscilloscope for iPad & iPhone
Oscium’s iMSO-104 hardware offers to turn your iPhone, iPad, or iPod Touch into a 12MSPS digital oscilloscope with an analog bandwidth of 5MHz. For folks like me with limited desk space & shifting work environments, that’s an interesting offer indeed. Oscium sent over a test model to take for a spin, so onto the spinning!
Digi-Comp II by EMSL (video)
Wow, check out the video tour of Evil Mad Scientist Laboratories’ functional recreation of the classic educational binary computer Digi-Comp II. Several weeks ago, we talked about bringing our giant Digi-Comp II to Maker Faire. But now we’re back, and we wanted to show everyone how it works– not just the many folks who came […]
Dog-Mounted Persistence of Vision Display
Michael Zoellner of Elangen, Germany, wrote in with a fun POV he created: Mounting 5 LEDs on a moving object creates one of the cheapest and largest displays: Persistence of Vision. It’s been done on bicycle wheels, fans and other rotating objects. In this project i am sewing a Lilypad wearable Arduino board and five […]
Engineer Guy on Cell Phone Design
Bill Hammack’s video this week explains the constraints that govern the engineering of cell phones, and how and why the development of key technologies has changed the way cell phones look and function. He also shows off the 8pen gestural keyboard app installed on his Android, which I immediately had to download and try for myself. Thanks, Bill, as always!
