[neonixie-l] Re: Russian IEL-0-VI 8 segment displays

[dr pepper]

Thanks Dmitry.

My Russian isnt good either.

A sine wave drive isnt so easy on a dc powered device, especially at
200v.
I could use an rc filter to remove a lot of the harmonics from a
square wave signal and produce an approximate sine wave, I dont think
these devices will use lots of current so that should be practical.

I'm still not sure if these devices have a backplane or common or
whatever, might have to sort that out when they arrive.

I've built a couple of the Midibox SID from donor (broken) C64's.
There was a listing for a variety of commodore stuff on craigslist a 
while back and I convinced the guy to give me all of his broken ones. 
Out of the stack, only 1 had a bad SID chip. The rest went into the 
trash bin minus their 6581 SID.

Re: [neonixie-l] bespoke case

[Nicholas Stock]

Kevin, I get cases made by a friend who runs his own acrylic fabrication
shop. The parts aren't laser cut, they're CNC machined from acrylic,
oversized at the edges and then polished down to give a nice edge. The
trick is in the bonding process of the edges to eliminate bubbles and
provide a clean bond without significant wash (from the solvent glue) on
the inside edges. Find a local shop if possible, but for low order numbers,
the cost is all in the labour, so don't be surprised to pay 50 or 60 quid
for a case if not more...

HTH.

[Smiffy]

If you're happy to do create the design files, I'd suggest you take a look 
at http://www.ponoko.com for laser cutting.

Different materials available from different manufacturing 'hubs.' If you 
want Perspex, you'd be looking for Acrylic, in their materials list. If you 
use the US hub, you may also have the option of polycarbonate, less likely 
to crack if you put screws through it.
