Just built a DIY LED Controller

I'm also interested.

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?

Now I'm extremely interested! Excited!

(mental note: learn arduino)

cggorman · 06-13-2011, 04:06 PM

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...

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.

The cool thing is - you don't have to learn ARDUINO. the controller is already programmed and ready to run. All you need are fingers or a pointy stub to press the buttons.

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

**IWANNAGOFAST** · 06-13-2011, 07:02 PM

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

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.

cggorman · 06-13-2011, 08:02 PM

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)

O2surplus · 06-15-2011, 04:54 AM

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.

cggorman · 06-15-2011, 01:44 PM

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...

liquidarts · 08-21-2011, 07:21 AM

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?

O2Surplus allowed me to post everything here.

Hope it helps.
