I have not installed plugs on my driver or on my series string. Just twisted wires together. Plugged bare wire ends of driver into extension cord. Could not having a solid mechanical connection be the problem?

Some more pics.

Here are some more pics.

I think I'm starting to get there.

Beautiful work. That's one big snowflake.

II am going to try to post some pics of each individual led in the string that I am working with. It seems that the image posting method has changed since the last time that I posted here (year and a half). I'm sure that I will figure it out. Here is where I'm at. Using 20 gauge solid bell...

Don't think so. I have gone down the string checking each led for function. They all worked and I never had to flip my tester to make one come on.

Just had some company arrive to spend the night. I will take some pics tomorrow. Just before my company got here, I inserted the blue leds into my series in the order that you suggested. Hooked up the driver...still nothing. I have tried two of my drivers. I will try another one tomorrow. I...

I recently decided to switch the lighting in my grow box from cfl to LED. My box inside dimensions are 23"x23"x45". I like to do things for myself, so I figured that this would be a snap. NOT! LED array design is rather involved and quite technical. At least it seems that way to me. I'm in...

I have been meaning to post a pic of my harvest on the scale. Well, I finally got around to it. Here it is. The other photo is of the clone of the plant that I harvested last month. The clone is the result of; after using the Uncle Ben topping method, I smeared cloning goop all over the cut...
