Put it in a box!
Everybody welcomes a good idea. Here is one for those who construct small circuits on prototyping board and then let them lie around without any form of protection, gathering dust. Such contraptions usually end up dead because wires come loose or components get bend, creating short circuits or bad contacts. There is a simple solution to this problem: put the project in an enclosure. It doesn’t have to be something fancy or expensive; in many cases an old audio cassette case is good enough. Transparent, easy to cut and open, they are perfect for the job. And they can be stacked, allowing your projects to be stored neatly in a drawer or cupboard.
