### 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](https://docs.slimevr.dev/diy/components-guide.html) - 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.
