i am back home after another incredible con.  I returned with t-shirts, badges, and bursting with knowledge. One of the fun and interesting message channels this year was Meshtastic,  Defcon had their own firmware again this year, but from what i hear, it went much better this year.  there was a wealth of information and humor coming over this tiny radio.

The Lonley Hackers Club was printing the meshtastic messages out of a receipt printer, the pile got pretty big.  Even the Bio Hacking Village added LoRa to their badge!
