I like to discuss stuff that's exciting, controversial, shocking, or, sometimes, possibly offending (Not an insult, a nudge). It's like looking under a rock and telling your friends to check out the new civilization you've discovered.
Most of the projects I dabble in involve constructing something. I can probably fix your computer or build one for you. I run neuroscience experiments using Lego, hot glue, Duct tape, Slinkies and Arduino
