I'm pleased to see how much instructional content is available for fledgling prototypers. I got into the field after reading Shane Colton's [http://scolton.blogspot.ca/] and Charles Guan's [http://www.etotheipiplusone.net/], build reports.

In a similar vein to the post material, Dan Gelbart's youtube course on rapid prototyping is invaluable: https://www.youtube.com/user/dgelbart/videos
