In the above two videos, done by our pal Jeri Ellsworth, computer industry legend Lee Felsenstein (member of the Home Brew Computer Club and Osborne designer) explains voltage dividers and how to calculate them. Things get pretty thick by part II and I pretty much […]
While I really like a lot of the “mechanical animism” folk-art sculpture that’s out there — people making robot sculptures out of found objects and retro appliances, comical scenes and dioramas using electronic components, cellphone charms and jewelry made out of electronic parts, etc. Most of it’s immobile.

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.
