Did you learn anything from our article on how to turn your smartphone into a microscope? If not then follow this link to get the instructions. After making a well performing microscope maybe it is time to go a little bit complex and venture into a machine that can make copies of your DNA. No, it’s not really complex as you will require less than 5 hours to do this with materials you can easily find around.

A DNA sequencing machine is basically a PCR or rather a Polymerase Chain Reactor. PCRs are used in a number of biological researchers and forensic investigations to amplify DNAs e.g. those collected at crime scenes. A Typical PCR costs roughly $10,000 but  Russell Durrett has devised a simpler, cheaper and quicker method that can let you have your own PCR.

What you need:

  •  PVC pipes
  • A 150-watt lightbulb
  • A computer fan
  • Acheap microcontroller
  • A few reagents
