Connecting Wires Artistically

To install the new burglar alarm I had to extend a power supply cable by cutting it and inserting a new piece of cable. It was important to preserve polarity. If I’d got the wires the wrong way round I’d have let all the smoke out of the device and its power supply. Which is a bad thing.

So I cut the wires as you can see above. This meant that it would be very hard to me to join the wires incorrectly. I’m quite proud of this, although it is probably something that everybody else has been doing for years.

Additional bonus: This approach meant that when I added the heat shrink tubing over the top of the joined cable the join made a slimmer lump.
