This week, I continued my work testing how to connect each peripheral device to the Jetson Orin Nano. There’s not much to update here, as I am still working on getting it done. I expect to have this completed by the end of next week. In particular, the I2C is a bit off, but I think it should just be a minor code fix that I need to resolve. The camera is in a good place, and I believe the data is being properly sent over the GStreamer pipeline.
One easy test was the USB C PD to DC cable. I have verified that with a 45W wallwart, it is able to power the Jetson Orin Nano from a USB-C power source. However, I could not get the device to power on using the power bank that I had at home. This means I must find a suitable power bank that can successfully supply the voltage and has more modern PD standards. It is important to note that the Jetson Orin Nano powers on, but I do not know the wattage that it is running at over the adaptor. It is entirely possible that it is only running at a lower wattage setting, so I will find a way to verify that it works at full power next week.
I have also begun designing two mounting systems for the device. One head mount and one chest mount. This is based on our weekly meeting, where we discussed that there may be some benefits to mounting the camera on the chest rather than the head. Once both designs are finalized and printed (or laser cut), we will test and compare both for user comfort and camera shake.
Regarding the schedule, I am still about a week behind the Gantt chart. This is a hold-over from last week, where I forgot to account for spring break on the schedule. For next week, I plan to finalize the peripheral integration and to continue working on the mounting designs.
