This week, I focused on testing the visor on a real bike ride and finishing up the communications pipeline by implementing LTE. Late at night on Thursday, I mapped out a ride to cover Lawrenceville, Stanton Heights, and Highland Park, into the Zoo. The roads were peaceful at night and the visor felt solid as I rode through the streets to collect data. I had made it into Bloomfield when I realized that I had forgot to enable GPS on the visor, so I went back to TCS hall to enable it. Once that was done, I took off on the bike ride again. Things were going very well until I got to the zoo, where the roads became very bumpy. Fortunately, the visor was resilient against all bumps and potholes up to that point. However, as I started to descend down One Wild Place, I hit an unexpected pot hole at speed, and I saw the visor launching up into the air as both the pegs and the zipties holding the visor to the basket catastrophically failed. The visor skidded across the asphalt in front of me, breaking into three pieces. The roads were quiet, so there was no one to witness the debacle nor be affected by it. Thankfully, the internals were fully intact and salvageable. For the future, it would be best to mount the visor with metal zipties or a thin braided steel cable to avoid the brittleness of plastic. It would also need better vertical reinforcement such as having an interface attaching the back of the visor to the front of the basket.
On the LTE side, I was able to finally get the gateway integrated with the Digi X-bee LTE board. Since the LTE board could not act as a network adapter that could give the Pi an internet connection, I had to modify the original LoRaWAN code to send packets to localhost:18500, and have a Python script intercept the packet and forward it to our LoRaWAN server. It has quite a bit of latency, but the gateway does come online without a WiFi connection!
In terms of other testing, I helped Stella weather test the CF final version of the visor.
