.. and you get to play with things that look a bit like ray guns….
My glasses fell apart a while back and up until now I’ve been making use of duct tape to hold them together. This works but it is not great from an elegance point of view. So I’ve got hold of some heat shrink tubing and now I’m using that. The repair is much stronger, and unless you know to look, much harder to spot.
Heat shrink tubing is wonderful. It is just strong plastic tubing that you can buy in different diameters. And when you heat it up it, well, er, shrinks, tightly gripping what ever it has been slid over.
It’s best to use a heat gun like the one above, although you can use a hair dryer at a pinch. If you are serious about building your own electronics you should definitely make use of the stuff, particularly when you are soldering wires onto connectors. It provides a strong physical support for the connection and also insulates pins from each other.
Me, I’m now saving for the huge expense of getting another pair of specs.
