I have been teaching classes on Arduino around the Minneapolis at Twin Cities Maker and at the Mill. There are two coming up in March and April 2012 at the Hack Factory, check the respective websites for more information.
I have also been teaching some soldering classes, more to come in the future, check Twin Cities Maker for upcoming events. Here is a picture of a student holding a genuine Wayne and Layne blinky POV from a class I taught with Adam.
I have been on a pro account on Flickr for 1 year now and have poster over 2,000 images. Most of are Twin Cities Maker. My profile is here.
