Seen this happen b4. Think someone posts and it is deleted by mods. Time stamp remains..
Just a guess though..
One time I just clicked the posters ID of the "new" post ..Didn't exist anymore..Leads me to believe the above..

Sounds reasonable

I purchased one of this board a while back and life happens. So i am just now starting the build. The issue i have is that the fans go to full when the lights go to 0% (off) but ramp with the lights from 1% on up. I what tried 3 and 4 wire fans. any ideas. I tried to contact O2surplus but my score is not high enough yet>>>

Hi-
I've attached a folder that contains a pre-compiled fan controller ".hex" file. In order to use it, please download the "Xloader" software found here- http://russemotto.com/xloader/ Use the Xloader .exe file to start the program. Set the board option to Duemilanove/Nano/Atmega328, set the Com port #, and set the path to the "perfected_fan_speed .hex" file. Tap the upload button. If all goes according to plan, the Nano will get re-flashed with new software, and your fans will function properly. Please let me know if you need any further help.

Hi all. I need a bit of assistance
Is there a 4a 12v led driver that can run on pwm?
I know the meanwell led kan do 1a at upto 52v but i would like to increase the amps en reduce the volts

Hey O2, thought you might like this one:

LDD's with your board for Apex dimming.

I think it took me a couple hours to wire this one, all that little wire is a real pain. ��

Tesadorn · 03/26/2017, 11:51 AM

Where can I buy the 1-10v to PWM converter by O2? I need 6 channels total for each light....

Which you can only do when you've built up a few posts! Have a look round the forum and join in

I once bought a EV-240 skimmer from someone in Swartz creek.. that wasn't you was it?

Nope, never had one of those. I didn't realize you were local, very cool.

Any more development on the ESP8266 Wemos control scheme?

I've tried getting the 8 channel Blynk setup from O2 working, and no luck. I also tried the SSLC16 project together, but I can't get it to actually load on the D1 mini.

I've sent a PM to O2surplus on several forums (including here) regarding buying PCBs, and never heard anything back. Does anybody have additional contact info for him that they could PM me?

lingwendil · 08/27/2017, 11:29 AM

Well, since several projects are dead in the water currently, I found a neat, simple, and affordable project for driving the LDD series-

Simple 16 channel driver with 12 bit resolution

This should be a good way to go for a larger fixture with many channel requirements.

Hi all, it's been a while since anyone posted on this thread, but I need a couple of technical questions answered. So I thought I'd try here, seeing as how all the experts have posted here in the past.

I'm building a DIY LED setup using 12 Lumia 5.2 pucks and 6 of O2surplus' PCBs with an integrated Bluefish Mini. I tried a PM to O2surplus but, haven't heard anything back.

My questions are:

1: the PCB has connections for up to 3 fans. Each connection has 4 pins (1- GND, 2- 12V, 3- Tack, and 4- PWM). My fans have 3 wires. I assume that means I must move the "Fan Jumper" to the 3-wire setting. So... which fan connection pins should I use, ie. 1+2+3 OR 1+2+4?

2: as my fans only draw .13A a piece, I will use only 1 SCW converter per PCB. Which of the 2 provided SCW connectors should I use - the one closest to the fan connection pins, or the other one?

3: I have 2 fans per PCB. Does it make a difference which 2 of the 3 available connectors I use?

Thanks...

If I understand he is having personal issues and has gone dark.

Dutchreef88 · 01/18/2018, 05:25 AM

Hi all,

I am having a weird problem with my LDD setup. I run the following setup:

- LRS-75-24
- 2 x meanwell LDD1000h
- The 14 up board from stevesled, basically it is 2 strings of 7*3 watt that are hooked up separatly.
- PWM controlled by Arduin

Now at full force there is no problem but as soon as i start dimming the LEDs with PWM my supply stars buzzing. I know this is Coil whine, but i wonder if you guys have any experience with this and perhaps maybe have a solution for this.
