This week I added in car’s to my algorithm, which really pretty much completed the core tech of the object recognition part of the project (all that’s left is pretty much adding training data and tweaking the parameters). I also fixed a few bugs I found in some of the knn stuff when testing. Me and Alli also went around with our wearable and took a bunch of pictures in different locations of runners and cars, which has helped me…
After doing the reading assignment, I was able to focus on my work a lot this week. I completely implemented a nodejs program using bleno to create the bluetooth services that I need, since the ones that are available on the raspberry pi built in will not work for our purposes. Initial testing with a BLE scanner app allows me to connect to the pi and use these services, so I have successfully transmitted data to and from the raspberry…
Sensor Issues This week I ran into a bit of a hurdle with the sensors. I would seemingly randomly get consistently false data (MAX_RANGE_VALUE) from the sensors that could be removed from restarting. It seemed to come from just one sensor, but to make it more difficult the port a sensor is plugged into does not correlate to the scanner port in the code. Ultimately I found that two sensors were stuck in configuarion mode and doing a factory reset…
