This week, I began work on designing the chest mount. This is being done in Fusion. I plan to laser-cut my initial design out of wood as a proof of concept. The final version will be made of either ABS or wood, depending on which is more durable and easy to mount the devices onto. I will also likely add either a foam or TPU pad to the underside of the mount, as having a hard chestpiece would be uncomfortable for the user. This will be a focus over the next week, as I want to wear the device. I also need to figure out how the harness straps will work, as I do not know how to sew.
With regards to peripherals. The camera may have broken. It no longer appears in “ls -l /dev/video*”, so I am unsure what happened. I plan to resolve this as soon as possible. I also got the VNC to work better by using a dummy DisplayPort plug, which tricks the Jetson Orin Nano into thinking it is plugged into a monitor. I opted to do this over running a virtual desktop, as I assumed it would be easier to turn off (just unplug it) and take less system resources. Another update is that I have confirmed that the Jetson Orin Nano works at full power over the USB-C PD to DC barrel adaptor!
Regarding the schedule, I am out of sync with the Gantt Chart. This is because some peripherals stopped working, and I must fix them. Next week, I hope to get the final dimensions sorted for the chest mount and try attaching the parts to the prototype. I have included some images of the current design (which is still being worked on) below.
