Hack your brain! Put on these glasses and headphones, close your eyes, and enjoy some harmless hallucinations as you drift into deep meditation. You’ll come out after the 14-minute program feeling fabulous. Sound and Light Machines (SLMs) help people sleep, wake up, meditate, and more. They work by generating light pulses (seen through closed eyelids) and sounds at brain wave frequencies.
With this kit, you’ll build an SLM for much cheaper than you can buy one. As seen in MAKE Volume 10.
