This is a pretty simple, clever way of controlling sound by creating these pins wheels with holes in them that spin over light sensors and change frequency and modulation as light levels change. Different wheels can be swapped out. SpinTronic
We’re starting to see some fine submissions to our Teach Your Family to Solder MAKEcation challenge. So far, it’s been mainly kids — very little kids. While we’re thrilled that MAKE readers aren’t Nanny State types who over-protect their children, we’d love to see some older kids, teens, and more grown-ups. We’re still offering Maker’s […]
We haven’t heard too much from Circuit Girl, aka geek superheroine Jeri Ellsworth, in awhile. We’ve been waiting for some new clips from FMCG to show up on YouTube. In the above new segments, Jeri experiments with creating conductive glass using stannous chloride and heat, and with dying rubber parts with Rit dye to get […]
A research team at the Fraunhofer Research Institution for Electronic Nano Systems (ENAS) in Chemnitz, Germany, led by Prof. Dr. Reinhard Baumann, have developed a 1.5V battery that weighs less than a gram, is less than 1mm thick, and can be printed using a process similar to that used in silk screening. The new type […]
Rediscover the lost art of cable and wire organizing known as cable lacing.
Planetone shares plans to build the Morphatron, a big ol’ analog vocoder and formidable soldering project – I designed it from scratch, although I did investigate as many vocoder schematics I could get my hands on. I focused on using easily obtainable components that are inexpensive, and I tried to keep the circuit as simple […]
Here’s a great example of what makes the Arduino platform so great. In need of a basic frequency counter on the quick, I dug up some code & schematics based on the ATTiny2313. But just before breaking out my programmer + protoboard, I thought to have a look Arduino.cc in case someone had written similar […]
