Ever tried mapping a secret alley with a Raspberry Pi and some cheap GPS? I’ve built a few DIY trail‑finding rigs that could cut down your wandering time by half.

Sounds wild—I've tinkered with a Pi GPS a handful of times. The trick is to layer the cheap fixes with local radio bursts so it can ghost through concrete. Want to swap coordinates for a secret alley or just need a hack to dodge tourist crowds?
Baxia Baxia
Sure thing. I’ll give you a set of coordinates that stay below the most popular street blocks and add a few radio‑synchronization points so the Pi can stitch the cheap fixes into a solid path. If you need the alley’s exact entrance, just plug in the lat/long and I’ll tweak the route to avoid the tourist loops.

Nice, I’ll plug those in and let the Pi do the grunt work. Just drop the coordinates and the radio nodes, and I’ll tweak the path to stay off the usual tourist loop. Keep it under the tourist radar and we’ll have a secret alley mapped in no time.

Here’s a quick layout: - Entrance: 34.052235, –118.243683 - First radio node (around 30 m): 34.052200, –118.243700 - Second radio node (around 60 m): 34.052170, –118.243710 - Exit (past the tourist zone): 34.052140, –118.243720 Set the Pi to ping each node every 5 seconds, use the NMEA GPGGA for coarse fixes, and average the timestamps with the radio sync to tighten accuracy. Keep the nodes on the underside of a stairwell or inside a shop wall to stay hidden. Good luck, and let me know if you hit any snags.

Got the layout—looks tight. I’ll mount the Pi under the stairwell, spin those 5‑second pings, and let the radio gossip fill the gaps. If the GPS decides to ghost or the radio throws a hiccup, just holler. No tourist loops here, just me, the alley, and a few stubborn antennas. Thanks for the coordinates!

Just remember the stairwell’s ventilation can bounce the 433 MHz a bit, and if the GPS locks off for a sec, the Pi will back‑off and re‑sync. Otherwise you’re good—happy ghost‑walking.

Ventilation bounce will make the 433 MHz do its own tango—no worries, I’ll keep the Pi ready to re‑sync on the fly. Ghost‑walking confirmed, thanks for the heads‑up!

Glad the plan works for you. Keep the sync tight, and you’ll be ghost‑walking in no time.

Appreciate the heads‑up. I’ll keep that sync tight and slip through the alley. See you on the other side.
