          Data-over-Audio/Sound
          The process of using sound waves to transmit digital data; sound waves are locally encoded and broadcasted from a device and locally decoded via another device or series of devices using speakers and microphones

          Tez,initial version of google pay user audioqr for communication.i am just interested in whether this tech is dead or not.i am curious in stuffs like whether we ca use it for positioning ,localisation, swarm communication etc

            @borncurious Okay got it. Yeah, Tez was really exciting in terms of how seamless it was. I really got astonished. when I got to know it was doing it over audio those days.

            So, are you looking for any libraries to do it or any sample projects?

              In the world of advanced optics and laser technology, Optical Grade diamonds are the new standard. Made with CVD (chemical vapor deposition) technology, these lab grown diamonds have high clarity, thermal conductivity and light transfer. The USA is leading the way with these diamonds, where industries from aviation to telecom have already used them. Not like mined diamonds, Optical Grade CVD diamonds are engineered for perfection, for high-tech applications across industries.

              What Are Optical Grade Diamonds?

              Optical Grade diamonds are CVD diamonds For very high precision and very pure materials.

              Ultra-High Transparency – Near perfect light transmission across UV, visible and IR spectra. Superior Thermal Conductivity – Fast heat dissipation for high power lasers. Minimal Inclusions & Defects – Critical for optical clarity and performance.

              In the USA, industries are moving fast to Optical Grade lab grown diamonds for their reliability and performance. Interested in Optical Grade diamonds for your application? Learn how CVD technology is changing the face of optics in the USA!

              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!

              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?

            • @salmanfaris Today I tried after connecting a 18650 cell,
              WhatsApp Image 2024-04-12 at 10.40.06_c7d1947e.jpg WhatsApp Image 2024-04-12 at 10.40.05_897b8bb6.jpg
              Data getting in console after integration of both lora and gps.
              3f45cfe7-0061-4328-8c55-ef0a73385203-image.png
              here you can see that GPS value is 0,0. also in my previous post you can see that GPS value is not reading.
              Also the status LED is active after it is connected to the satellite.
