The people in this community hope for a world where an individual's informational footprints—everything from an opinion on abortion to the medical record of an actual abortion—can be traced only if the individual involved chooses to reveal them; a world where coherent messages shoot around the globe by network and microwave, but intruders and feds trying to pluck them out of the vapor find only gibberish; a world where the tools of prying are transformed into the instruments of privacy. There is only one way this vision will materialize, and that is by widespread use of cryptography. Is this technologically possible? Definitely. The obstacles are political—some of the most powerful forces in government are devoted to the control of these tools. In short, there is a war going on between those who would liberate crypto and those who would suppress it. The seemingly innocuous bunch strewn around this community represents the vanguard of the pro-crypto forces. Though the battleground seems remote, the stakes are not: The outcome of this struggle may determine the amount of freedom our society will grant us in the 21st century. To the Cypherpunks, freedom is an issue worth some risk.

AI summary of transcript:

groundbreaking exploration into transmitting LoRaWAN signals via unconventional means—utilizing microcontrollers lacking native radio functionalities. By tweaking GPIO pins on devices like the CH32V203, ESP32-S2, and ESP8266, OP demonstrates how to generate RF signals strong enough to communicate with commercial LoRaWAN gateways and access the internet. This method deviates from traditional approaches that rely on specific radio chips or RF capabilities. The experiment not only surpasses expectations in terms of signal transmission distance but also showcases a novel blend of ingenuity and technical prowess. Through this project, the resilience and adaptability of LoRa technology are put on full display, proving its capability to facilitate long-range communications under inventive conditions. The venture into RF technology and signal generation through hardware manipulation opens new avenues for utilizing microcontrollers in ways previously deemed impractical, marking a significant achievement in the field.

How long before someone figures out that a whistle in a cereal box can resonate tinfoil at just the right frequency to generate LoRaWAN signal? Then we will have come full circle back to the good old days of phreaking.

Great, so now I have to worry about esp32 going rogue and transmitting out data to some far off person. Guess my next house is gonna be a faraday cage

Everything is an antenna if you try hard enough.
