  1. https://github.com/F5OEO/rpitx You don't need much to spam random RF energy into the air. That project just flips a GPIO pin at the right frequency, and gets a signal into the air. It won't be very powerful, and the harmonics will probably…

  5. …files, lol libs used = LLMed up the ass. Someone pointed Claude (yes, CLAUDE.md is in the repo) at https://github.com/F5OEO/rpitx and told it to wrap it around in fluff go code, then sprinkled profanities and pirate theme on top.

  6. One doesn’t actually need any extra hardware for this… just 8cm of wire and this https://github.com/F5OEO/rpitx (use at your own risk of course)

  10. …varies by country/frequency/power level. Can also make a Raspberry Pi act as a transmitter ( https://github.com/F5OEO/rpitx ), which could hit the zwave frequency but not the zigbee one. (Also, make sure to put a low pass filter on it.)

  12. RPITX is the spiritual successor of your project! https://github.com/F5OEO/rpitx And it does work with nearly every RPi. And unlike only doing FM (97MHz-108MHz), it can emit from an IQ datastream from 10KHz to 1.5GHz.
