I just got back from the plastics manufacturer once again, and have some new bits and pieces to play with.
The fascia has now been corrected so that the volume knob is seated centrally within the surround, eliminating problems with them rubbing. We'll send out replacements to "mini batch" Mk.2 owners in the next couple of weeks.
We've chosen the tints for the four main colours, and have worked hard to come up with dyes that maximise the display brightness. The blue screen is now a lighter shade, more towards cyan than pure blue, and is about 50% brighter than the screens that shipped in the mini batch. The green screen is brighter than the Mk.1 version, a slightly lighter shade, and hopefully a better match for most green illuminated dashboards. The amber is a close match to the Mk.1 shade but is at least 20% brighter. The red has an orange hue, as promised, for a good match with BMW and Audi. It's the least bright of all the colours, but is still brighter than the original blue screen.
Because the VFD has a blue/green tint, we've had to use a relatively low density dye to get acceptable brightness on the red and amber panels. As a result you can see some of the components behind the screens in daylight, but there's not much we can do about that. We don't want to print a mask because it will reduce the viewing angles, but if you're a techie type you might like the effect :-)
I'll get photos of each of the screens onto the web site soon, probably tomorrow.
