Drugs are so passé. The 21st century way to turn in is by hacking your brain - and the hack itself is a DIY. The resultant machine flashes LEDs in your eyes and blips sound in your ears to sync your beta, alpha, theta, and delta brainwaves, allowing you to take a trip whenever you like, legally, and without the traditional destructive effects associated with controlled drugs. It'll be interesting to see how governments respond as devices like this become commoner and finer-tuned. [GT] Make your own Brain Machine [via MAKE]
