The doNExT has arrived:
I ran a quick check cuz I ain’t got no time right now: it rings (so at least the UID reads) and the blinkies light up. But it doesn’t read through my wrist, and barely through my hand. Maybe it’ll do better under my skin. That’s with an ACR-122U.
Also, I can see there’s potential to create a multi-coil configuration and address each blinkie separately. I’ll get cracking on that when I have some time.
For now it’ll sit in its pouch until Sept 5th, and I’ll read it every now and then, to give it some time to fail if it must.
