Sounds like a great project on the bake. If you know your way around coding, then perhaps just start with the LoPy4. It would be more than capable of interfacing with any RFID module that has a serial interface (with the exception that the pins are limited to 3.3V logic).
The last thing for me would be confirming the ability for this reader to read animal EID tags.
If my thought is correct, watching the frisbee video was like sheep running through a gateway (smarter people out there please don’t steal this one on me )
Only thing i’ve really found to help me with this outside of automated dog/cat feeders (which are really cool to) is
The simultaneous reader appears to have a wide range for frequencies.
I’m not aware of maker-type products that support ISO FDX-B, though there are countless commercial chioces out there. Animal “microchip” also operatate around 135Khz from memory, and that is well below modern simutanious UHF-type tech.
We have an internal cat door that separates two parts of the building here at home.
The idea is that the RFID reader - coupled with a direction sensor - will be able to record the passage of our furry monsters, and in what direction.
It’s all part of my Big Brother-style plan to be able to find the buggers (as they have a knack for hiding from us - a luxury we’re not afforded in reverse).
They’re sufficiently different in colour that if this fails we MIGHT be able to do something with a camera and some cloud-based AI to do the same trick. If there are two eyes in shot it’s coming at you, one and it’s going away.
That project’s still a while off, backed up behind the Cat Wheel Speedo, which is suffering decimal point problems with the stupid upside-down Adafruit display.
