Agenda:
- Project sharing
- Test audio recording using sound cards
- Test battery
Tasks Accomplished:
- Tested mono recording using binaural microphones and sound cards
- Bought identical mono USB sound card adapters to convert mono recording to stereo recording after some modification
- Bought a tester to test the battery voltage when not in use
After our project sharing, we went on to test the audio recording and the battery voltage. There are 4 smaller cells in the battery we use and to make sure that battery is not undercharged and works, we have to test the voltage of each cell using this battery tester and make sure it is above 3.7V (otherwise we would have to charge the battery).
We continued testing the audio using the sound cards and confirmed that the sound cards are able to record mono-recording using microphones. After some discussion, we have decided to try to achieve stereo recording by splitting the stereo mic jack into 2 mono USB audio adapter using connectors which means that we must buy 2 soundcards (preferably the same soundcard). We opted to buy another Flujo USB soundcard adaptor instead to because the Vention soundcard which we bought is meant for earpieces that come with a mic and takes TRRS connector. If we make the splitter with the TRRS connector, it will not work with most devices/ sound adapters. In our case however, we choose to make a splitter with TS connector so it will work with most of the available sound adapters.
Waking up early in the morning for the presentation and pressing on to finish up some of our tasks made it a long day! Take a good break and see you soon! 💃 🕺💃 🕺
