A while back I saw an EMF (Electromagnetic Field) Detector at makezine.com that used a led bargraph. I decided to modify it to use a 7-Segment LED Display! Here’s my project. Sorry I don’t have any pictures of it in use. Hopefully I can post some soon. Credit goes to Aaron ALAI for the original project.

Touch screens are two dimensional input devices. Nowadays most of the electronic gadgets use them. Laptops, smart phones, tablets and even some home appliances like washing machines & microwave ovens also use a touch screen nowadays. Why Touch screens? Touch screens are preferred over keypads because they need very little or no pressure to operate whereas

I was looking at all those swoopy-zoomy internet connected and controllable thermostats. “Self,” I told myself, “we should make one of those.” He didn’t seem all that excited about that – I mean, what do we know about hardware, firmware, electronics or HVAC? Well, now’s as good as any to figure it out. So without

Lab Experiments involving the Heat Equation are usually one-dimensional exercises involving a copper pipe and a half-dozen thermocouples. But with DS18B20 “One-Wire” thermometer chips and an Arduino, it’s possible to measure hundreds of temperature values simultaneously. Here’s what my students Daniel Lund and Lawrence Lechuga and I came up with for 2-D temperature measurements. We began by
