PCR machines are too expensive for biologists who want to build their own labs. A couple of weeks ago I struck on a publication by Brian Blais on the DIYbio forum detailing a working PCR machine that he built in 2002 using only a light bulb and a steel pot. Oddly no one else has expounded on this idea, so I decided to build a better prototype with an arduino and only products available from Home Depot and Radio Shack.
In the end it cost me less than $50 to build this machine (including the $30 arduino). There are about a hundred different ways I could think of improving upon my build, so this is only a start. I’ll be sending it off to GenSpace in the next week to undergo some serious testing, but until then you can see the details of the build on this site:
Check it out and let me know what you think.
Here is a video explaining the project:
