### 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:

|
#### 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.
