In last week's MacGyver Challenge, we asked you to hack something using heat shrink tubing. We received some great entries, but the winning hack shows us how to keep those jangling keys silent.Check out the description of the winning entry below and read about some of our other favorite entries.
Sick of the sound of jangling keys and dog tags, Profound found a clever way to silence them. He fits a piece of heat shrink tubing over the head of the key, heats to shrink, and then trims off the edges. Though you could use the many colors of heat shrink tubing available to color-code keys, we kind of like the transparent look—especially for things like dog tags that you still need to be able to read. Sure beats wrapping them in duct tape! We got a lot of great entries and we'd be remiss if we didn't share some of our favorites. Here are some of the entries that really impressed us.
Bbaks used heat shrink tubing to create a clever solution to tangled headphone cords. By sectioning off the cables with the stiffer tubing, he created a cable that folds up accordion-style and never gets tangled up. He adds that the solution works best with the thicker cord you find on over-the-ear headphones. When he tried the same trick with the thin cord on a pair of earbuds, the tangling problem actually got worse.
FidesOnus uses a Helping Hand clamp tool to hold parts in position while he works. He found that the bare metal of the clamp often caused damage to delicate components like printed circuit boards. His solution? A bit of heat shrink tubing applied to the tips of the clamps protects those components while retaining full gripping ability. A big thanks to everyone who took the time to send us entries! Be sure to check back every week for a new challenge.
