We had our first go at experimenting with potting the waterproof gland and cable connections with epoxy for the waterproof enclosure today. We stripped the ethernet cable plastic back with a scalpel to expose the copper then separating the wires through a plastic disk. Meanwhile the steel wire armour was enclosed between two M20 washers to hold it out of the way.
Unfortunately the wires are very brittle and we will need to re-think this with a junction box and without the toilet roll epoxy container, but it was a slight rush to get something together.
Many thanks to Richard, Barnaby and Paul who done a 2am stint with me at Reading HackSpace to put this intial prototype together!
