Signal Hunt: An ESP-NOW Workshop & Treasure Hunt

Hello everyone! We’re planning on organizing a two-phase event that explores device-to-device communication using ESP-NOW protocol :

Workshop: Participants learn to build and program ESP32-based receivers with a web interface that directly exchange signal data using ESP-NOW for RSSI-based distance approximation.

Signal Hunt Competition: Equipped with these receivers, participants will track hidden ESP32 transmitters scattered around the campus, each with distinct point values.

Current hardware setup:
Reciever(one per team):
Esp32 ~ 360rs
9v battery = 20rs
9v battery clip= 5rs
buck converter (MP1584 or LM2596) ~ 45rs
Perfboard + male to female berg strip ~30rs
Total per reciever ~ 460rs
Transmitters :6
Components same as recievers = 460*6~2760rs

(using non-rechargeable batteries to reduce cost,
will using a 7805 voltage regulator IC be a viable way to reduce cost further?)

We’d love your suggestions on ways to simplify hardware, reducing the cost, secure partnerships and funding, or enhance the interactive elements. Thank you, looking forward to any ideas that can help make the event engaging and successful!

So today, I was reading about a kid who got a custom prosthetic arm printed like really. Holly molly! People are printing prosthetics nowadays! That’s when I stumbled upon Curewith3D, and wow, 3D printing in healthcare is on another level.

Apparently, I found out that they’re not just 3d printing limbs. They actually use patient-specific scans (like CT/MRI data) and some DICOM files to design prosthetics that fit the person’s body perfectly. Every angle, curve, and dimension is matched to the individual. No more bulky or uncomfortable fits.

What’s wild is how fast and affordable the process is. Instead of traditional molds and weeks of waiting, Curewith3D can design, print, and deliver a customized prosthetic in a fraction of the time.

I didn’t know 3D printing services could be this life-changing, and it's happening right here in India. It really makes you wonder what else we’re going to be printing next.

Anyone else heard of this or know someone who’s used a 3D printed prosthetic? Would love to hear more.

I am trying to set up a janus webrtc to stream an RTSP to an HTML page.
I have followed the getting-started steps by Janus-gateway official github repo.

Since I am new to web development. I do not understand how to host the Webrtc server. can anyone guide me to set up an HTML page that can display a video stream from an RTSP server using janus webrtc?

@zainmuhammed Can try capturing the GPS when the device is starting the loop instead after joining the LoRaWAN and see?

You can put the GPS value on top of the loop or setup function.

Also, what kind of gateway are you using? Is it configured okay, OTA is done?
