This project was cannibalized over a year ago. With Raspberry Pi as difficult to get ahold of as they’ve been, i thought this project might never come back to life. I launched a number of pi liberating ideas with some success. I now have enough for both fun personal projects and to get my work done. I felt i should explain the name wardriving. It is a variation on wardialing. Wardialing was trying phone numbers, looking for interesting things on the phone. Wardriving is similarly driving around looking for interesting things in the air.
My wardriver is not pictured above, but these Pi are ready for whatever comes next. I’ve recovered an assortment of different Pi from original B+ (pi-hole) to a 2GB Pi 4 (broken helium miner). One of the best parts of this setup is the early Pi 3 (not B+). This was a lucky find as it consumes less energy and produces much less heat. With only 6 radios running (including GPS) the lower performance hasn’t been an issue, but the reduced power has been incredible. Early testing has me getting an additional 20-40% battery life vs the original pi 4 configuration. my cable management has also improved with this iteration. The setup fits in a small box in my trunk instead of a tangled mass of wires in a large bin (prototyping is fun). The reason power is so important because, believe it or not, the amperage you can pull out of a Tesla for accessories is limited. Without an alternator dumping piles of unclean energy i am forced to resort to BYOB (bring your own battery). I got a monster battery to power the Pi 4 and even more radios and accessories of the original prototype.
It is fun using the ADSB live tracker in Los Angeles as there are always planes above. Next step will be DJI drone tracking and some sort of dashboard indicator/control. I started a WiGLE account, it’s off to a pretty good start. i found a few APs, but i’m still figuring out how to share BT. maybe i’ll join the #HardHatBrigade group.
