Russ, I have a chance of a 128x32 Vishay 12v plasma DMD.

Do you think there is a chance your Dad will get that power board fettled? If not I doubt I'd ever get it working.

Thanks.

[russdx]

Sorry to insist russdx, but why do you prefer the plasma, I'm just trying to understand your opinion.

I also don't like too bright displays, to not be dazzled in the dark.

It's difficult to choose without testing, so I need as many information as possible.

iv only played with a pin-led display not the vishay led versions so they might be alot better i dont no but i do have a 192x64 plasma dmd and i much prefer it to the pin-led. all the pixels are perfectly spaced, it has a much softer orange/brown glow to it. the pixels are much smaller with more space around them.


you can buy 12v vishay plasma dmds but they are $$$$ - led versions are the cheaper alternative.

ouch to the price though!! lol


my dads a bit busy at the moment so i dont think his plasma driver board will be done any time soon

Have you got a data sheet for the Vishay DMD's that need the weird voltages russdx?
There is a place that I have got custom transformers made that would be able to wind the transformer needed for this then it would be a case of working out the recitfication and filtering/conditioning for each of the voltages. Just curious to see what it would cost to build.

Hello maxxsinner,

Do you see the defaults on your vishay that russdx sees with his pinled?

Have not tested the LED vishay as yet. Have a board on the way from russdx so will post some video as soon as I can of the results.

I was only asking about the power requirements for the Plasma version of the DMD to see what was required to make a compatible power supply and what costs would be involved.

[russdx]

datasheet is here
datasheet


my dad did say some thing about if he could have a custom coil wound it would sort out that problem. ill ask him exactly how it needs it wound

maybe we could get them custom built as well

starting to mass order some parts for an initial 30 piece run

found a company that can make the pcbs + assemble for a decent price as well!!

I have a spare pinball 2000 transformer I could part with for a nominal fee if someone wants it for this project.
I am in eastern PA but won't ship it (too heavy) so if you are in driving distance PM me.

did the pinball 2000 machines use the old dmd displays? the transformer would have to be from a pinball that used a original plasma dot matrix

[luvthatapex]

Nope the pinball 2000 machines used a CRT display, but supplied all necessary voltages to be downward compatible with other components.
The same transformer would have the voltages needed (80v and 100v) for the DMD display for this project.

update on plasma dmd power board


my dad is saying to get this done fast and easy he needs to take apart an existing 12v plasma dmd (used on the 192x64 games).

problem is, im not gonna rip my one apart as they cost like £400 / not gonna buy another just to take it apart. its not worth it.

i really need a broken one so my dad can take it apart and see how it works. does any one know the best place to get a broken 192x64 dc plasma dot matrix?

i know the old williams dot mation slots used them as well.


or a schematic for the 192x64 integrated power supply version would be perfect.

EDIT

i found the schematic for it !!!!
will show dad see what he thinks

Wow. Still moving at lightning speed I see.
Even with the broken down car.

[russdx]

cars still in garage, warranty hopefully covers the damage or thats gonna sting lol

working from home so got a bit of spare time to plaaaay



dad seams very happy with the schematics so looks like the 12v plasma driver board is back on

[chriz]

awesome news! can't wait for your set

[russdx]

gonna be a while for the power board its not really my project but my dads n he not got as much spare time as me hehe

[ced]

Cool , thx at your dad !!

ced.

[russdx]

little update



got my second board made today (had a short which took 8hours to find ahhhhhh).

but its all working cool like the first one. so it think these boards are cool.

second i hear back from maxxspinner (confirm it works with vishay led range) and my warranty i will get a little batch of 30 boards made up

if they all sell ill make another batch of 50

[arngrim]

Thank you for the feedback russdx, I will receive my vishay led in the same time that i'll start my cabinet build then

What is your estimate for delivering the first orders?

Arngrim

[russdx]

not sure iv never had a small batch run of boards made and assembled before, if i go ahead soonish id say about 1 month ish

alot can go wrong though to dont quote me on that lol
