Hi all, I'm trying to guage if this is the right place to come for some advice on some DIY electrics. I'm from Derbyshire, I'm a climber, a total electronics self taught novice, and I'm converting my van into a camper. I've done all the wiring and everything is gravy with that. Solar is in, battery charger from engine hooked up, fridge in, lighting sorted...all good.
However, I'm trying to cut my foam mattress in half. When I say in half, I mean down it's depth. So it's 1.8m x 1.6m X 0.2m and I'm trying to cut it down to 0.1m / 10 cm depth. To do this I'm thinking I need a hot wire, heated by passing a current through some nichrome resistance wire. Would anyone be able to help me by recommending what kind of power source I might want, what guage I might want to make the wire, and if I need to take any particular precautions?
Many thanks to you all
