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. https://image.nostr.build/0cface07bd08b56f865f5d22bc8080eef96c1cad26df65e30f13ae15ef717b4e.jpg
I mounted two kinds of devices on cardboard for Show&Tell purposes. https://image.nostr.build/b0ba85d7c6a12872fc5c14f7b00aab1f1fe0f2b3f7afa754b0677ea67d913fdf.jpg
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.
