Has anybody on here had an experiment with the supermarket tags?
My understanding is that you get a bunch of the tags, somehow get a base-station/transceiver working with them, and push data as images.
I'd love to hear from anyone who's had a go. I quite fancy having some little displays around the house with useful info for the room.
I have a few Pricer* ones and they're a pita to use.
Have to build an IR blaster to program them.
You also can't use them once the battery is flat or if you remove the battery because it uses volatile memory to store the firmware.
What the what?!
Yuuup, they use an ASIC too.
Here's an attempted teardown https://www.youtube.com/live/AN0CMmFQIi0
