Me, at our #bitcoin #meetup, holding forth on #Meshtastic and #Cashu #eCash for a local #CircularEconomy.

Those are #LoRaWAN nodes precariously balanced on the brim of the small tote.

I mounted two kinds of devices on cardboard for Show&Tell purposes.

The pinnacle of the demo was me walking around the block, all internet access shut down, voice to text reporting my location over the #SpreadSpectrum LoRa Meshtastic link between the devices.

Also sent some SATs as a Cashu token.
