Some cool resources for Homebrew Science

While researching homebrew chromatography, I got seriously sidetracked by several cool blogs on DIY science. DIYBIO4Beginners is over a year old, and has a huge number of posts covering mostly practical aspects of learning about Biotech and DIYbio. Of particular interest are the posts that contain video series’ teaching you about Biotech/Biochem, or “How-To”, etc. There's a lot of stuff in there, much of it news coverage, but the signal-to-noise is really excellent.

Makerbot Update - Broke, Fixed, Printing!

Well, since my last post the Makerbot has been busy! Busy breaking and requiring troubleshooting and maintenance. But that's behind us now; I've a lot more knowledge of Makerbotting, and a much tougher Plastruder as a result. Many, many thanks to Mark Adams for the replacement part he printed and sent to me! It Broke So, I'll keep it brief. The Makerbot is prone to a failure that occurs when plastic melts too high up in the barrel; this leads to increased friction, but also to some molten plastic being shoved up into the insulator by displacement as the filament forces its way down.
