Dremelfuge Classic loaded with tubes
The Do-It-Yourself-Dremel-Centrifuge, DremelFuge, now nearly meets the capabilities of the best centrifuges! As previously posted for DIYbio (in “Cathal has designed a simple centrifuge using open source hardware technology, and you can order one yourself!“), the DremelFuge is an adapter which turns a Dremel rotary-tool into a lab-quality centrifuge capable of use in various bioprotocols.
As Cathal states on the DIYbio mailing list:
“After a design revision which is now “official” and for sale on Shapeways, the Dremelfuge can hold tubes securely, with liquid load, up to the full speed of a Dremel 300. At a top speed of 33,000 RPM, this means the tubes experience about 52,000RCF (g).”

We had our first DIYBio workshop in Broad Hall on the UCLA Campus over the weekend. The student community from both north and south campus were involved, which included art and science/math majors.
Romie Littrell started things off with a short presentation on the concept and history of DIYBio. His talk kicked off discussion focusing on the safety and security of biotechnology that is open to the public.

The highlight of the workshop included an extraction of DNA from everyday food products, akin to the extraction of DNA from strawberries.

Other demos at the workshop included a sampling of a biological polymer made from cornstarch and other products found in every kitchen. The red color and taste reminded me of Twizzlers.

We had a diverse group of visitors throughout the workshop over 4 hrs. Other than science and art professionals, a lawyer and stay-at-home mother with toddler came to participate.
