OK, I've finally got around to testing out the new transformer with my plasma display and everything works well. Here's a very crappy cellphone video of it in action:
If I place an order for 25 or more transformers, I can get the price down to around $35 each. I reached out to the manufacturer of the DMD Piggy and inquired about a bulk order as well. He said that he would be willing to customize the board size, connectors (e.g. molex for 5 and 12V), and mounting points, but that I'd need to order a minimum of one hundred. I'm not sure if there's enough interest to warrant that large of an order, though.
That said, even though I probably could put together a package using the off-the-shelf board, I don't think I'm going to pursue it. Quite honestly I don't know if it would be worth my time given the presumably small demand. However, I would be willing to order the transformers and help out anyone who is interested in getting a plasma display up and running. If you're interested and are comfortable pairing the transformer with a power supply board and doing your own wiring, send me a PM with your email address and shipping zip code/country, and I'll keep a "pre-order" list. When/if 20 or so are accounted for, I'll place the order and will send out invoices ($35 + shipping from Phoenix, AZ) when I have them in hand. Lead time once the order is placed is around two weeks.
Here's the transformer spec to get an idea of mounting dimensions:
Feel free to send any questions my way.
EDIT: Oh, Kris - I haven't seen you around on the forums lately, but if you still haven't got your display working yet and would like to give one of these transformers a shot, let me know!
