Well, what doesn't it do? Um... OK What DOES it do? Well, it gives you a super nice RGB power indicator LED with 8 modes!
Q: But how?
You might ask. Well, it overloads the functionality of the volume and brightness buttons. Yes you heard me right!
Well, I thought of that too! If you give a button a "short press" it forwards the volume or brightness signal as a clean pulse.
If you hold the far left button for a few seconds, the LED flashes RED 3 times and puts you into programming mode.
Once in programming mode, the two left buttons cycle you through 7(or maybe eight, we'll see) modes.
The two right buttons change the setting for the mode you're currently in.
When you like the look of the LED, you press and hold a button (I forget which one - offical instructions will come with the board), the LED flashes GREEN three times.
This commits the setting to the MCU EEPROM and, wait for it.... The setting you chose persists even through a power cycle!
Q: OK, what are the modes?
Here's a brief summary of the modes:
0: Red Only : 16 brightness Steps Adjustmet
1: Green Only : 16 Brightness Steps Adjustment
2: Blue Only : 16 Brightness Steps Adjustment
3: Custom Color : Above R,G,B Brightnesses are mixed!
4: White Only : 16 Brightness Steps Adjustment
5: Static Rainbow : 256 step adjustment through spectrum
6: Changing Rainbow : Color change speed adjustable
7: Temp Sensing Color : Managed to get this fully working!
This may seem a bit steep for an LED button Board, but I'm taking into account the work I put in and the fact that there will be a somewhat limited quantity(I have about 20 PCB blanks for this one). But here's what I came up with:
Fully Assembled: $40 + Shipping($5 for First Class, $8 for Priority to US destinations).
Q:How do you install it?
Yeah, you have to dig pretty far into your Color Classic to put one of these babies in. To me that'll probably be the most significant hinderance to getting a lot of orders for these. I'm not sure I want to create instructions as that involves working with components that can store high voltage even when unplugged. If I provide instructions, and someone get's zapped, I could be open to liability. So, Officially, I say have this installed by a competent technician who is capable of CRT based equipment repairs. In a nutshell this involves(THE FOLLOWING ARE NOT INSTRUCTIONS!!) Opening the case, removing connections at the CRT, separating the plastic chassis carrier from the front bezel, carefully opening the front of the EMC shield(edges and corners are sharp!), and swapping the board which is mounted via 2 screws and connects to a card edge ribbon cable connector. OK those were NOT INSTRUCTIONS, but here is what one looks like mounted on the chassis:
