I think it was the below - note this is in New Zealand dollars (half the value of US dollars).

Appreciate this! I did see some plastic ones around this price range, I guess it was just a bit more than I expected to pay. I noticed that this one just has leads- did you wire it into a plug yourself? Any concerns around doing that in a waterproof way?

I often find that "prototyping" these types of projects is fairly easy, but making them into a "product" that looks good and will be reliable is much much more difficult.


I found a transformer with bare wires that was the right voltage and wired it up.

It was from a local electronics store (Jaycar).

It’s in a dry area so getting wet isn’t an issue for me.

I think I could make it quite tidy and waterproof if I needed too - the lower voltage makes me comfortable with that.

It’s been in use for several years now and has been rock solid.
