Hardware is supposed to be:

  • Cheap
  • Off the shelf and readly available
  • Easy to work with
  • Fast enough for send a live stream

So far all the boxes have been check by:

Base components:
  • esp32-cam
  • ov2640 IR with 160 degree FOV
  • esp-32 programmer

Alternative possibility:

  • raspberry pi zero
  • ov2640 IR with 160 FOV

Powering it on:

Just like a slimevr trakcer

  • 2x1N5817 SCHOTTKY diodes
  • TP4056 USB-C charging board
  • a bipositional switch
  • A 800mAh Li-Po battery

This will make the eye tracker last for about 9 - 10h of playtime.

One could also power it though a USB port as the esp requires only 5V and 300-500ma

A usb battery or two lipos with a 5.1v power regulator should also do the job.

Radical alternatives for a camera

Shave off the IR filter off of any camera module: https://marksbench.com/electronics/removing-ir-filter-from-esp32-cam/

Ommited because of safety

I'm ommiting any IR emmiters here purposfully - I have no idea if any of them are safe to use for prolonged periods of time and thus I leave them out.
