Agenda:
- Use audio splitter, connectors, mics and sound cards to achieve stereo recording
- Discuss how to use IMU or other methods to achieve greatest signal strength
- Try writing the code to extract signal strength from webpage
Tasks Accomplished:
- Made an audio splitter which works (yay!) 😁
- Took down a couple of things which we needed to research on
Is it finally… FRI-yay?
We started off the day soldering and making the audio splitter for the binaural microphones so that it can record stereo sounds using the rpi. Basically, how the jack of the binaural microphone works is that there are three sections to it – Sleeve, Ring and Tip whereby the Sleeve is connected to the GND, Ring is to the Right microphone and Tip to the Left microphone. We made use of some TS, TRS connectors and some wires (soldered one female stereo connector to two male mono connector) to make the splitter work!! It was fun DIY-ing! 🤗 🤩 🤗 🤩
After considering the issue on the rotation of the transceiver on the tank, we decided to try to use both the IMU and extraction of signal strength to rotate the transceiver to the best position.
We did try writing the code to extract signal strength from the webpage (accessed using IP address of the transceiver) but we could not really achieve what we wanted… we’ll complete this task next week! 👑👑👑👑
