Intro: Secure Your Arduino/electronics Project With Sugru
[This instructable is a result of the 2013 Sugru Build Night at the Warsaw Hackerspace]
Sugru makes for great electrical insulation and it's way easier to apply than heat-shrink tubing or hot glue.
Here's an example of securing soldered connections of an electronics project.
Just make sure you do not short the wires while applying sugru! :)
