This week we started receiving materials for our project and began testing their functionalities. We received our sensors, blues starter kit, microphone, batteries, and our raspberry pi hat. Our current risk is stable mounting of our device to bikes. Our current implementation relied on a velcro strap which we realized after using bikes this week will be unstable.. Most bicycles use a mounting clamp to add accessories so we’ll do the same. We’re redesigning our encasing to be compatible with the NiteRider Tail Light Strap Mount.
Since last week we decided to eliminate the web server aspect and will have all of the server processing happen on the raspberry pi. Two main reasons for this: sending audio to blues cloud is very inefficient due to the round trip latency from sending back and forward through the cloud to an internet-hosted server. Thus not using the Blues cloud will reduce latency and it’ll be cheaper since we won’t be charged for each block of data being sent to the Raspberry Pi.
