If you want to get into electronics, it’s pretty straightforward: read up a little, purchase a breadboard and some parts, and go to town. getting into molecular biology as a hobby, however, provides some challenges. The knowledge is all out there, true, but finding the equipment can be a problem, and what’s out there tends to be fiendishly expensive.
So numerous would-be biohackers end up making their own equipment, like this diy gel electrophoresis rig. Electrophoresis sorts macromolecules like DNA or proteins by size using an electric field. For DNA, a slab of agarose gel is immersed in a buffer service and a current through the tank moves the DNA through the gel. The shorter the DNA fragment, the simpler it can wiggle through the pores in the gel, and the quicker it migrates down the gel. [abizar]’s first attempt at a diy gel rig involved a lot of plastic cutting and solvent welding, so he simplified the process by using the bit plastic drawers from an old parts cabinet. With nichrome and platinum wires for electrodes for the customized ATX power supply, it’s just the best size and shape for the gel, which is cast in a separate mold. The video below shows the whole build, and while [abizar] doesn’t offer much detail on recipes or techniques, there are lots of videos online to guide you.
