Fair enough Pewter.
I will provide updates here, although, I'll keep the updates light and
infrequent. I doubt people want what are essentially marketing updates
very often.
I wouldn't expect a realistic retail level release until mid may.
Once I feel the project has grown up enough, I'll send
I switched to sodium/potassium persulfate a while back myself. It was a
good switch. Just make sure it's nice and warm. I typically heat mine to
110-120f before I start etching. The higher heat makes for cleaner
traces, and a faster etch.

Maybe you have the polarity backwards? Switch the positive and negative
leads.
I've seen this before, but I cannot remember the solution.

Hi folks,
not everything is done yet, but the largest part. I have documented
all my glow lamps and Nixie tubes so far. See here:

I have only looked at your schematic for a few minutes, so I may not
completely know what is going on.
The first this I see that I do not understand is here I see the opto
isolator. As I understand it, you are planning on running the leds
through it.

the active display is brighter than the inactive one.
Hadn't considered. Truth be told; I saw the LED back lit clocks and
basically thought it was a cool idea.
I do not believe anybody has suggested 50/50 copper sulphate/table salt yet.
For my first try, I was going to try a concentrated solution of ferric
chloride and voltage with stainless as the anode and cathode.
I do not know how it will come out.
I'll also go grab some copper sulphate to give
Ahh, found some nitric acid.
The 6 molar solution should do nicely.

Really?
Well, that's worth trying.
Maybe a better etch could be gotten with the use of a combination of
ferric chloride and electrolysis.
That would probably mean a printer based press-n-peel system and a battery.
I am also interested in this method to make stainless solder stencils at home.
I don't know about 3d printing the cathodes.
As for chemically etching these plates, I am pretty sure you won't have to
put the pattern on both sides of the plate.
You could completely cover one side of the plate with a even coat of etch
resist.
Then, you'll be able to put your design on the
