After much thought about what I am after with the Express I decided to go ahead and add the second option I wanted on it. Now first this is optional, it is not required but this will be most likely the last dimmer I do for a while so I want something I am proud to stick my name on.

As you already know their is the option to have an Led for each channel so you can test and see the channels trigger as on the 595 boards for example. They will dim with the channels. This option cost about $2 for the 16 Led's.

Then I thought about how I need to add a power indicator on the Express. But what I really wanted was a way to tell what channel the board is programmed to instead of writing it down or not knowing and having to reprogram it just to know what channel it is programmed to.

So I added 3 LED digits to the board and the driver for it. This way once the board is boots up the start channel is always displayed so you know it is powered up and the channel. It will also show when you are in program mode. And it opens other possibilitys with just firmware changes to use it for diagnostics etc in the future.

This option is a pricey one at about $5 but I will have it on mine as I see it being worth it.

The nice part is you can build it with or without either or both options, your choice.

Looks REALLY cool!  This really opens up a whole new world!  I have a question about the Triac's.  Is there enough room there for heat sinks or are you figuring they wont be necessary?  Just havent seen them aligned that direction and made me wonder.

Just curious more than anything.

Hi RJ,

Looking Awesome

One question: The hole pattern for the fuse is different then your other designs. I am assuming you are using a different fuse holder. Right?


Many thanks

Can't wait to have some Express to play with.

looks like it might be for a little higher Amp fuse? 15A?

It's the same Fuse setup I used on the Lynx. It is a little larger but room was no problem. Yes it is 20 amps as thay is what the load will be limited to with the single power cord inlet.

 At this level with a 2 amp limit per channel no heats sinks will be needed. This is the common for commerical units like LOR is to allow 2 amps on these triac with out heat sink and I have operated them that way. This is 600 minis a channel or about 5000 Leds per channel so I think that is acceptable. If you tried to run 2 amps on them all this would be 32 amps so I feel it is plenty.

I have the firmware mostly done. The exception is the program mode to write the start channel and the dimming curves.

I went ahead while I was at it and made it handle multiple curves per controller. This lets you run different types of lights on a Express and associate that channel to the correct curve for the lights you have attached to it. I set the express up to handle four different curves at the same time. This means you can use four different types of lights on a express with their own curve.

My plan is in the programming software you will have four curves with pull downs to choose which curve that slot uses.

Then you have a drop down for each channel with the four choices you made available.

I attached a pic of something I threw together to show kinda what I am thinking.

That curve selection program looks to be readily adapatable for RGB LEDs    ;D
 

One more addin - a hue vs RGB table   >:D

P.S.  Absolutely Excllent RJ...        (hm      I just may have to jump on the bandwagon here)
