I'm installing an air quality monitor outside my apartment. I have no power outlet outside, so I have to plug in the power supply inside and run the wire through my wall. The collected data will be shared via wifi. The wall is concrete, and the power supply is pictured below.
I'll need to drill to route the cable, and I'd like to drill as small a hole as possible. This presents a couple of challenges. In order to fit the head of the USB cable through the hole it'll need to be around 11 or 12 mm, and even larger to fit the ferrite bead. I would like to avoid drilling such a large hole.
In the interest of drilling as small a hole as possible, can I cut the USB cable and solder it back together once it's been threaded through the hole? This would mean that the hole would only need to be a few millimeters wide. Assuming I go this route, must I reconnect all interior parts of the USB cable (the bare copper wire, the foil shield, the red 5V cable, the black ground, and the other two data cables)? Or can I get away with just reconnecting the 5V and ground cables?
Obviously this would mean I would have to cut the cable again if/when I decided to move it. Is there any way to avoid this? Are there other connecters I could use for this sort of purpose? Is there something else I haven't thought of?
