Where did you find the IR beam break equipment? We have a medical situation with one of our cats and need to limit food access in different ways and different times. We really really appreciate your design and want to implement it. My husband is a developer and we can print the designs, which are very impressive. Thank you for sharing it.
Here is an Aliexpress listing for the power plug https://www.aliexpress.com/item/32812877104.html

I checked the Adafruit datasheet. Looks like its "QT50CM" Here is an Aliexpress listing for the same sensor. https://www.aliexpress.com/item/1005008867308826.html
I suspect its from Adafruit, like the micro controller mentioned on his blog. https://www.adafruit.com/product/2168
