I would add some ferrite beads to the wires on the connectors.

You would be surprised how much RF they can conduct.

I’d be interested in seeing more detail about the hole punches you’ve used. I have a Bosch pillar drill and a stepper bit which works reasonably well but the working area can be small, because of the space between the bit centre and the pillar - it’s a small scale, home use one rather than a bigger workshop one.

For a customer visible project I didn't want to use a re-purposed biscuit tin ( the less people understand about the electronics the more they nit-pick about presentation).

I bought some empty paint tins from Amazon. They are lacquered which is a shame (but I suppose if not they would be rusty.)

Oh, that's a great point on the paint and coating.

It is one of those "that's obvious--now that I see it" kind of things!

Great ideas! I will have to try some of these techniques out some day!

Good idea. I need to get to the shop to buy a tin of Quality Street - easy now the Christmas stuff is being stocked [emoticon:79b09143209a47198626541757c5862f] Hopefully, I won't damage it and have to acquire another!

I used to work with circuits that were sensitive to mechanical noise. A handle on the top side and clips to lock the lid to the base were useful to suspend the box from the ceiling with long surgical tubing/bungee cords. Late shifts were on order too, to have a quiet environment.

Sorry no pictures, I would need to break into the former work-place.
