Suggestions for automating manual LGB points

[Alan McLennan]

I would also suggest that you use a conformal coating if the boards are going to live outdoors.
This will greatly reduce moisture ingress into the boards that will lead to corrosion and possible de-lamination.

Couple of examples

Personally I would use the second one (the urethane, used in the RAAF on avionic boards) as it will be easier to rework the board if needed.

Dielectric strength... now that's what I'm talking about!
I'll look into it, my power at this moment will be via 12v dry cell battery as used in alarms, with a main switch to turn all power off and a solar trickle charger,
the control switches will be in a box, and servos as before. I knew a few people who moved to Bundaberg.

Similar to my set up SLA battery with solar panel and master switch.
I'm using waterproof 12V -5V DC converters for my servos Waterproof DC-DC Converter 12V Step Down to 5V Car Power Supply Module 3A AUS A | eBay

I'm using RG59 coaxial cable to get power outside, why because I have a 300M roll left over from a past life.
I use19mm poly irrigation pipe as a conduit.

Bundy is a great place Goldilocks temps; not to hot, not to cold, just right and it has a running 1:1 cane railway for me to play with.

That converter looks the go, and I will be running Cat6 ethernet cable as I have a load of it from when a mate gave me 4 boxes of it when I was doing our CCTV around the house
the irrigation pipe is a good idea as well. I'll tell my mate to wear a hat so you can spot him up there Gap.....
