Beautiful faceplate TMZ. Would you share the video link that Lee's referring to?
Not sure if all of you have seen this but I thought it would be a cool replacement for PL meters. The builder is in Romania and I've swapped a couple of emails with him. Sounds like he could do a custom size but his tone isn't all that anxious. Maybe something lost in translation.
A couple of issues would be the power supply driving his display may generate some internal noise and this is a frequency display and not a power level display. Looks like there's some customization available for the opening credit and colors used also.
From what I can tell it doesn't look like an Arduino board but I'm not all that knowledgeable about those things. These were available on eBay last year for around $100 each.
Whatever you think of it.... it's really cool looking!
