Nowadays you can find instructions for make your own scientific instruments on different sources. Until now by the means of browsing trough biohackers forums or in DIY repositories ( i.e www.instructables.com) interesting examples can be found.

The information quality is better in peer reviewed journals, however in internet forums also exist a better interetaction between the authors and the folk interested in the project. What is your opinion?
