Photic Driving Experiments

2022-11-16 at 9:17 AM UTCIn short: PHOTIC DRIVING is the effect where if lights are strobed at specific frequencies (usually 3-20hz, but higher frequencies have been tried too) in your eyes or against closed eyelids, it'll induce direct brain activity at the same frequency. Medical techs use it to test brain function in people who aren't responsive as well as to calibrate instruments, check for epileptic response and other things.
What I'm more interested in, though, is the long history of reports of altered states of mind going as far back as the ancient Greeks suggesting that 'trance' states could be achieved through staring at torches flickering at certain rates. I'll post some articles and reports and stuff later, more just interested in the project than the theory at the moment.
Basically just an Arduino Ethernet (ATMEGA 328) with a screw terminal breakout board to make connections easier and an LCD display/button panel (link)on top. I've connected two RGB LEDs and tied them to a pair of swimming goggles (I'll make the surfaces semi-opaque later, maybe with paper or contact or maybe white paint).
BEcause of the GPIOs the LCD panel needs to function I had to wire the two RGB LEDs to D0,D1,D2 and D11,D12,D13. You cannot program an Arduino board via USB while pins D0 or D1 are in use, apparently, so to update the code I need to unplug those connectors, then plug them back in once the programming's done.
All this does is flicker the LEDs at a specific rate, and you can use the buttons on the panel to either disable or enable the lights, or to adjust the flicker rate up or down without having to re-deploy or use a serial line or something.

2022-11-16 at 9:23 AM UTCI SPECIFICALLY wrote this in such a way that it'd be easy to add/change the type of LEDs used, the GPIOs they're plugged into and stuff like that. I'm fully aware that this is (relatively) very slow and I'm rewriting a bunch of shit to move it faster and reduce load, specifically:
- hardcode pins instead of using loops to cycle through the arrays
- use AVR PORT commands to turn lights off and on rather than slow DIGITALWRITE
- see if I can find a crystal clock for precise measurements instead of the internal AVR chip's clock, which is not precise
but I also want to be able to test things like different colours and different frequencies for either eye, so I can't just hardcode everything down to the hardware level for pure efficiency

When you get it down pat you can hook it up to the Christmas tree lights outside your house and put all your neighbors in a trance like state so you can then suggest salacious things to your neighbors wives.

I prefer the blinking variety that induce neighborhood seizures -
