Faced with a broken USB dongle for our wireless devices, most of us would likely bin the part and order a replacement, after all the diminutive size of those things probably means hard to impossible repairability, right? Well, [The Equalizor] took it as a challenge and used the opportunity to practice his microscopic soldering skills just for funsies.
The wireless adapter in question, which came from one of his clients who accidentally bent it while it was plugged into a laptop, refused to be recognized by a computer under any circumstances. After sliding out the metal casing for the USB plug and snapping off the plastic housing, [The Equalizor] discovered that the slightly bent exterior hid a deeply cracked PCB. Then, with an inspection of the severed traces and lifted components, it was simply a matter of reflowing solder a few times to try to make the board whole again. Once the dongle was confirmed working, a new 3D shell was printed for it, replacing the original which had to be broken off.
It might not seem extraordinary to some people, but this video is a good example to show that repairs to delicate electronics in such a small scale are feasible, and can serve to reduce the amount of electronic waste we constantly dump out. Just because some electronics seem dauntingly elaborate or beyond salvaging, it doesn’t always mean there isn’t light at the end of the tunnel. You can see the work performed on this tiny dongle after the break.
