IoT Light Sensor: There is Data!

One of my goals for the IoT light sensor was to explore graphing live data. Phant, the Sparkfun service I’m using to post my data online, has an example of graphing live data with Google Charts. Since I know nothing about coding for the web save some outdated html and css knowledge, I used their example code as a template for what I wanted to … Continue reading IoT Light Sensor: There is Data!

Electronic Mural: Charlieplexing with Paper Circuits

As I’ve mentioned, I’m working towards an electronic mural using Chibitronic circuit stickers and a Circuit Scribe pen. Today I prototyped the entire circuit on paper. The fun part was using the microcontroller circuit sticker–wicked easy. I used an Arduino UNO as a programmer (tutorial for setting up the board) and Arduino software to write my code. It took maybe 10 minutes to get up … Continue reading Electronic Mural: Charlieplexing with Paper Circuits

Induction Motor

For my Power Electronics Lab, this week, we built the three-phase drive for an induction motor. Induction motors are pretty damn cool, and while I think they are the hardest motor to understand, they certainly have the most interesting torque speed curve. And induction motor is basically a series of coils that you run current through one by one. The coils are the stator, they … Continue reading Induction Motor

Small Walking Robot

I’ve been wanting to make a walking robot for a while and found this awesome 3-servo design in Make magazine: It’s very simple and appears to walk with a shuffling motion, kind of like a duck. It’s a pretty clever design: basically a flexible parallelogram that is rotated by a servo. The parallelogram acts to move the legs up and down. Each leg has … Continue reading Small Walking Robot
