On PCR And Genomics

"The polymerase chain reaction (PCR) is a biochemical technology in molecular biology to amplify a single or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence. PCR is now a common and often indispensable technique used in medical and biological research labs for a variety of applications. These include DNA cloning for sequencing, DNA-based phylogeny, or functional analysis of genes; the diagnosis of hereditary diseases; the identification of genetic fingerprints (used in forensic sciences and paternity testing); and the detection and diagnosis of infectious diseases." (Wikipedia)

Now those PCR machines can be pretty expensive...

... or they can be hacked in a fablab, for free use... The PCR machine you get to see in the video below (at 5:57) is 10 times less expensive... (you can activate the English subtitles in the bottom bar of the video)...
