If you really want to understand electric circuit theory, eventually you will need to come to terms with Ohm’s Law. So how can you get the concept across that I=VR? Will your students be able to figure out that V=I/R or that R=V/I, or that all three of these equations are pretty much the same? […]
Danny is a frequent user at the Boston Fab Lab. He has done some great work to figure out the laser cutter. In nice Fab Lab community fashion, Danny has encouraged and tutored many other lab users on how to get the most out of the tools in the lab. The Boston Fab Lab is […]
Last week at the Duxbury Student Union, Lee Pulis and I held a workshop on using trash to learn about electricity, design and mechanical devices. We used CD drives from old computers. Inside the drives we found motors, gears, switches, and lots of interesting looking stuff. The main tools were small phillips head screwdrivers and […]
Via BB, Kevin Kelly writes: This is Tanya Vlach’s new eyeball. She lost her real one in a car accident a few years ago. I met Tanya at a film festival recently. During our conversation she said she was looking for help in turning her artificial eye into a eye-cam. You know, a mini web […]
Lukas sent me a link to his new project that encourages people to learn Processing. The idea is to make a B/W monster in Processing and post it on his website. All the monsters are interactive and the source code is available to download. I really like “Blink Eye Monster”, and look forward to checking […]
Relays are used in a lot of electronics projects, but did you ever actually think about what makes them work? This website has a ton of information on various relays and how they work. Read All about relays In the Maker Shed: DIY Design Electronics Kit
Yes, I know it’s Wednesday! Consider this post my Special Post-Election Edition of How-to Tuesdays! This week I made a USB7 6 Digit LED Display Kit from the Maker Shed. It’s a really cool electronics kit that can be controlled from your computer via USB. I decided to modify it a little so it’s easier […]
