Led the complete plan

[TheShadow]

sorry to ask do you have any picture of your boards hooked up

 

[TheFishMan65]

There are pictures of my rev 1 board in my album. Do you want a FTS or what? I am a little confused.

 

[TheShadow]

I apologize for the confusion. I have been reading these forums for months trying to get a handle on this project. (Which would not be possible without any of you)
Some patterns are beginning to emerge. I am not alone in my understanding so little.

The only way I can help all of those trying to understand this it to be the dumbest individual attempting this project.(not a far stretch)
If you can walk me through it step by step others could use this to complete there projects without bothering you guys with what you consider 1st grade questions
You guys are running; some of us are barely crawling
Trust me I hate asking these questions but I have no were else to turn.

Again please stick with me.

 

[TheShadow]

that said what is FTS? see i wasn't kidding("dumbest individual)

Full Tank Shot
TLA (three letter acronyms) are a bit of a pain, when in doubt try this thread

 

[TheShadow]

Thank you sir
could you look this over and see if it is correct so far with the drivers.

I am doing one with yours soon as i find all the labels and connections on the images you have

 

[TheFishMan65]

I am not sure that link is good - I can't seem to load the picture.

 

[TheShadow]

having more problems with picture I cant figure out how people are getting such good quality

 

[TheShadow]

try again

Move the whites to the same board (center ?) IIRC the 3x board has only one PWM input. You want to be able to control the color separetly.

No pot on the fans. Are tehy 12 volt and a 24 volt supply. If the LED current is low enough save some money and use the same poer supply.

 

[TheShadow]

I put the leds on the drivers from left to right in order to possiply simulate sunrise and sunset with the PWM. Is this the wrong idea?. also without a pot on fans they will run at full all the time(12v) will that be needed?

If I go with your board would I not go from these 3 PWMs to 4 PWMs alowing more control of sunrise sunset?

 

[TheFishMan65]

The pot means you need to be thre to adjust them. Forget and leave them low and you may (or might not) have problems).

Most people seem to raise the blues then the whites for sunset. My board could go to 6 with minor changes, but finding a controller that has 6 PWM maybe more difficult.

 

[TheShadow]

so the idea is to raise them all at once not from right to left?

 

[TheFishMan65]

That is what I will do (right now they just go on and off). I also think most people are doing that. I have heard the east to west mentioned, but I have not heard of anyone actually implementing it. In terms of real life IMHO the four to eight feet of ocean we are simulating will not see different level of sunrise or sunset. Also as mentioned I don't know of any controller that handle more than 4 channels, doesn't mean there are not any.

 

[TheShadow]

working on the refinement's now. instead of a POT perhaps an on off switch

A picture of your 8 board all wired up.
revamped the diagram this setup would require 3pwms on per board correct. yours would require just 2 one for the 2 string whites and one for the 4 string blues is this right?

 

[TheFishMan65]

From most controllers (I'll more familiar with the Hydra) you can drive several CAT4101s with a PWM. I think the limit was near 10, I would need to look that up. So you could get by with one PWM going to all three boards or connected to all PWMs on my board. In the 3 board version the maximum (with out board modification) I believe is 3 (one for each board). With my board the maximum (without any modification) is 4.

I just noticed in your diagram that you are missing a 5 volt supply to the CAT4101 boards. that same 5 volts can go to PWM (for always on) until you get your controller up and running.

 

[TheShadow]

If I am going to dim lights using the Hydra I will need to use two PWMs? one for the 2blue boards and one for the white boards correct

"I just noticed in your diagram that you are missing a 5 volt supply to the CAT4101 boards" Not sure how to do this yet trying to get these pieces together 1st.

Hydra

Hydra

Is the hydra controller out yet?

 

[TheFishMan65]

I actually believe the Hydra could supply the 5 volts. Or you could find a separate supply.

PM me your email. I will send you some information on my board.
