Of course the can never told me to not put another coat on after the paint dried... everything flaked off the box (not the lid, which I did not paint again)

So... after a bunch of acetone I stripped the paint off the box and put some new stuff on. Oh well, sht happens.

When painting over a dried layer of paint, it's recommended to lightly sand the surface so that it's no longer shiney. The new coat will adhere much better.

No, the old coat peeled off. :-/

That aside, the new coat is on and in a few days it should be hard to the point in where I can handle it without leaving marks.

Just an idea for when it works, xray a nixie.
Might look cool.

Because the head is separate from the control box, I'll be able to x-ray the x-ray machine itself!

Waiting for the paint to harden sucks...

That's actually what gave me the idea to xray the nixies wink
I wasn't sure if the xrays would ruin the arduino or anything.

Did you find a box for the head yet?

This paint is still soft, and leaves marks when handled. I hope it will dry before I grow old and die...

I got impatient and put the box together. The paint is curing, albiet very slowly. I'll just avoid touching it until it's cured.

Turned out pretty well, even if it isn't perfect. Now I just need to make it work because right now it's just a fancy box with knobs on it.

Time to buy some lipos. I settled on a 4000mAh 14.4V one and a 3000mAh 22.2V one. They'll go in series and the 14V one will also supply power to the control circuitry and tube heater. (tis the reason why it is larger).
