[TriEmbed] Waterproof Connectors

[Sofie Permana]

Have you tried Sugru to cover the gap between the cable and the housing? I
tried to connect a drilled glass bottle and a small plastic pipe using
Sugru before and it is both air-proof (small pressure) and waterproof. With
a good pressure, I can also take release the pipe/Sugru off the bottle too,
so I think it is releaseable.

of waterproofing using Sugru, because I can't find the one I used before)
