Accomplishment: This week I set up a network connection on the Jetson by connecting it directly to a Wifi router, which allowed me to install pip and a GPIO library. After resolving multiple permissions errors, I was able to run some sample GPIO control tests using the library. Since I still had not heard anything about the transistors for the PCB being delivered, I tried soldering wires to the PCB so that I could use a breadboard transistor, but in doing so I broke one of the solder pads on the PCB. I also placed an order for the USB audio output converter.
Progress: I had planned to finish populating the PCB this week, but was set back since the transistors still hadn’t arrived. I contacted Quinn about the order, and he said the transistors had been delivered but I wasn’t contacted about them, so he will check for them on Monday. This put me behind schedule, but since the transistor is only used for interfacing the vibration motor with the Jetson, I am still able to test the buttons and ultrasonic sensor using the PCB. I am behind on my progress due to the transistor delay, but hopefully I will be back on track after assembling the new PCB.
Projected Deliverables: This week I plan to populate a new PCB since the first version broke. I will test the buttons and ultrasonic sensor using the PCB, and will solder the transistors and test the vibration motor once I get the transistors from receiving. Once the audio converter is delivered, I will work with Shakthi to develop the test-to-speech audio output.
