O2Surplus allowed me to post everything here.
Hope it helps.

I'd like the eagle files if yor willing to part with them.....are there any difference in components for the 5v and 10v versions?

|cggorman||I have access to an oscilloscope and various other testing equipment, but I would think somebody here is MUCH closer to you and also could lend a hand...|

|O2surplus||Well I'm still working on the "D" version. It seems to be a little more difficult to change a 10 volt PWM signal back into a linear voltage- than first thought. I've found some information that indicates that an OP Amp circuit can be used to do it, but being that I no longer own a oscilloscope, it will be tough for me to verify. I'm not giving up- It's just going take a little more time to figure out.|

Oh, I thought this was just a bare board and a BOM! Even better!
Put me down for enough to operate 3 "D"s & 1 "P" (on same tank)

It should come in under the $50 dollar mark. I'm working on a spread sheet with the bill of materials and links to all the parts right now. I'll post it up in the near future.

|IWANNAGOFAST||I'm very interested. Very VERY VERY interested! What kind of stuff did you program into the controller?|

|Rockhoe14er||I interested too if the price isn't too much because these day's i'm pretty poor and need to save.|

|evilc66||They do, but poorly. You get about the same results as trying to drive a "P" model with an analog voltage. It's not worth doing. The results are much more consistant when you drive the input with the appropriate signal.|

|cggorman||I was wondering if the "D" series would accept a 10v PWM signal. I know my digital multimeter interprets a PWM output as the analog equivalent...|

Now I'm extremely interested! Excited!
(mental note: learn arduino)

|O2surplus||Ok, so there are some interested parties. I'm going to take that latest design "back to the drawing-board" for a good reason. It's compatible with the MeanWell ELN "P" series already. I'd like to add an on board option to make it compatible with the ELN "D" series too. This feat shouldn't very difficult, I think the addition of a crude digital to analog convertor circuit could do the trick. Does any one know if I'm on the right track? yes/no?|

|cggorman||I'm also interested.|

Actually there are several companies that produce some wicked-large LED drivers, I've seen (if I recall correctly) Meanwells and Thomas Research drivers that go up into the 100-200v range (DC output).
