Do It Yourself : How to Build Hallucinogenic Goggles This post will describe how to construct a pair of goggles which can be used to induce geometric visual hallucinations (123) via strobe light patterns. This tutorial should be accessible to anyone familiar with Arduinohacking, and I do not go into details of the electronics design. The effects are quite remarkable. These goggles can be constructed for 25 to 50 dollars, depending on how good you are at scavenging parts. I believe this design to be superior to some similar designs seen on the internet, and very much cheaper than this commercial equivalent ($649). Do It Yourself : How to Build Hallucinogenic Goggles
