My New 64 channel controller

Recommended Posts

To get an idea of size, there is a chair to the bottom right of tree and a small step ladder to the left of tree.

Very nice. I saw channel count earlier in the thread, but how tall is the tree?.and how many strings (60 single strings, one per channel, or more?)...

Great looking set up, would you mind telling what you used to mount the boards to the box, it appears to be glued in? I believe I read that you used low power heat sinks is that correct?

Thanks,

Mike

I glued strips of wood painted black to the box. Then screwed the boards to the wood strips. Since the tree is 100% LED (except the strobes), the whole thing only draws under 2 amps. So yes, they are low power heat sinks.

Denise, You inspired me !

Here is my version the "CTB64SB"
I had some materials around, the board guides, standoffs, etc
I will use this for my mega tree this year freeing up 4 other controllers to use elsewhere.
I also doubled the mass of the heat sinks, there were several low power plates around from other kits I completed using the high power plates.
I put a slight bend in one of them, put some heat compound between and bolted the whole mess together.
I, like yourself am in a colder climate and use LEDs so no issues with temp.

Thanks for the Idea !

Steve, this is gorgeous. You should think about being a reseller.

I need to do one for 48 channels for a tree; now I'm having to decide between the "denise design" or the "steve design", as it is obvious there is not enough time left to create the "don design"..:)

I'd love to see these pictures but how do I get to them?

No problem Tony...I asked the exact same question about a year ago. Nice to know I retained something taught to me.

Hey John,

 

That controller was built two years ago.  I will look for a link to a video that I have up on You Tube

From the pic, it looks like you ran power and Board dongles
through the same hole and Cat5 through the other. Am I seeing it correctly?

Second, if I am seeing it in the right way, it looks as though you used a
jumper between boards for the ground and the power. Is this what I'm seeing?


Power in to first board,

  • Jumper to second terminal and from that terminal,
  • A jumper to the second board, etc.

I am in the process of emulating your design and I want to get it right. Are my assumptions correct?

I will be running 80 strings total from 64 channels. 32 white from 1 board and 16 apiece on boards 2-4. The strings are 70 ct. Full Wave LED at .04 amps per string. My whole set-up

will be running ~ 4 amps total. I think I’ll be ok as far as the power is concerned.

Much of this electrical stuff is over my head, but i'm curious why you would not want to connect all the grounds on the controllers as well. I understand from other threads that the ground protection does not extend to the 2-wire strings but thought there still was some advantage to grounding the controllers.

Hi TonyD,

 

This issue is a toss up. Now if the controller is in a steel case like the PRO models are. Then there might be a case where the steel case of the controller is mounted on something wooden. And there is a short that would energize the case. You come along and touch the case and you are grounded. You have just been shocked. But if you mount the controller in a plastic case and even if it is mounted on the ground. I would hope you would remove power before going into the case. In this case, a ground wire going to the controller has no real benefit. I have 10 of the PC versions and not one of them have a ground wire. Cause I power down before opening the plastic cases.

 

Thus the reason to use ground faults.
