DIY Radeon clone?

[danielch2008]

Easiest thing is to go with the 5 channels and use a TC-421 with the wire modification as I showed you earlier.
There have probably been dozens of Aduino/Pi/esp32 controllers built.
Though successful none are really "plug and play" and few have an app.

I have a "guy" in Spain that built me some 5 channel driver/controller boards.

Uses a phone app and AP or Wifi
They are customizable as to mA output.
Boards above are set at 700mA 5 channels each.
60V maximum
I've used 2 over my 40b for over a year now.
I have not tested them at 56V though.


They sell just the driver on Tindie.

Multi channel led driver Analog or PWM dimming up to 20kHz

Very good. Tell me more about this board

 

[danielch2008]

I tell with your friend of Tindie, but tell thar only one unit is more expensive. Too did see that board with 12 channel have more funcion that with 5 channel

Which board?
There are 2 above
The 3 driver only board was new.
The driver/ controller is a simple design( my request)

Ramping is over 15 min/ period not continuous from time a to b
Has a choice of 4 types of ramp curves ...linear or 3 different gamma curves.
No lightning or clouds or lunar cycles.

Basically a sunrise/ sunset controller.

I'm using a raspi 3, with Mike's Reef Pi Hat with a PCA on it. The hat is powered via a 5v 2.1a wall plug. The pwm channels from the HAT run to Rapids 4up and 4S-up with 700ma LDDH x6 and 350x2 for 8 total.

Each color has its own dedicated channel. The pucks are Xr30 pro clones with 8 channels.

I also tried hooking up 8 K16s to see if pucks were an issue, they did the same thing. Starts flickering when 5 or more chsnnels are powered.

Does your rapid LDD board have somewhere to plug in GND for pwm? Mine only had 1-4 ch PWM.

Any chance you could post pix of your setup? The drivers, PCA board/pie?

hello friend, I'm trying to do something similar to your project. I've been looking at your posts and I say congratulations. I have a doubt... you put some devices on your board, can you explain to me what they are and what they are for, their functions...

This is more simple. Have other with 12 channel que have Smith control brightness app etc.

Think you are referring to the 10k resistors and black jumpers to err "activate" them.
https://rapidled.com/products/ldd-h-4-driver-board

Includes pull-down jumpers to turn default dimming ON/OFF without dimming signal

Yes. This are thar funcion?

Limited to 48v maximum
I purposely requested the design handle 54+ volts.

Have with do diy bluefish or Storm X(with controller app) ? Arduin... in web site od Tiende tell which boards eletronics

 

[danielch2008]

another thing... I'm noticing that aliexpress ldds boards are wider than other manufacturers like Steves Leds boards (seem much narrower)

Voltage only means something to the driver.. Storm and Aduino would dim LDD's..which have 56V limit.

 

[danielch2008]

Tc421 i think that have more that 56v

 

[oreo54]

Tc421 i think that have more that 56v

tc-421 is just a controller. The power limitation IF used as a constant voltage strip controller is a 12-24 single voltage and 4A per channel
20 total..

This board is 5v would it have to be 56v correct?! there's no way to feed her separately if you can't...

What is this your request?

 

[oreo54]

What is this your request?

I don't understand the question.

The controller/ driver board was built to my specifications.
The software was also built to my specifications.
The driver current on each driver was configured to my specifications.

There are only 5 drivers/ channels.
There are only 10 programmable points per channel ( need to check again, may be 12).

Eu não entendo a pergunta.
what is this controller board?

You can contact the above person for the boards.
They are in Spain

s
ordered parts arrived. Designing the housing in 3d print and looking for a dimmer board that has multiple channels.

 

[danielch2008]

the electronics technician didn't solder it properly and probably shorted out some leds. Is there a connector that can be soldered more easily and to not have this problem of wires coming in short when they bend?
