Hi Dave,

I was going to design a cover that enclosed the bottom.

So the cover would slide over the Trump card PCB, maybe like othef QL expansions.

I have 2 Trump cards, one without a cover. But I never liked the Miracle cover.

I would then produce a 3D Printed version and replace the 7805 power regulator with a DC-DC converter, giving no heat.

Oooh, interested. I've got nowhere thus far with my vague notions of getting a cover on my clone. I briefly toyed with the idea of a 3d print myself, until I realised that I would actually need to have some idea of what I was doing.... :-)
