So cool! I’m trying to convince my parents to let me get an NExT (i’m 16). I’d also probably go through a similar path to you in terms of more implants (something capable of payment and one with an LED). Not too keen on the magnet implants just because of MRI scans, but i think it’d be pretty cool too.
Could you post pictures of your garage door setup? I wanna know how/where you’ve mounted the coil.
