Thanks I sent him a message! (Tesadorn was made as I forgot the login for this one hehe)
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?

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.

Need a little help with O2surplus' 6 channel PCB
Need a little help with O2surplus' 6 channel PCB
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...

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.

Many say it is peizo electric effect from ceramic capacitors..
But you could start by changing PWM frequency in the Aduino..
Only real suggestion is a mechanic stethoscope to pinpoint it..

The poster of the image needs to pay photobucket.
Maybe viewer too. Don't know..
no more free lunch..

Basically PhotoBucket removed the 3rd Party Hosting of Images (last year)
Mean you have to pay a TON $s for that 3rdParty feature if you want your old images to re-appear.
It's nothing to do with VIEWER.
If you haven't noticed old image posts from past show that error message. (for Everyone)
There is a hack to fix this (may not last forever), but works.
Edit any Post with your image (reefcentral opened up re-editing of old posts). Was suppose to be a deadline to do this last year, but it appears the re-edit is still working).
You can either replace the image from another PhotoHosting repository (like Flickr) but that's a lot of work.
Or a quick fix is EDIT THE POST (Keep the PhotoBucket URL exactly like it is) and add the following to the Image URL (at the end of it [no-spaces] ) add "~original". Hit save and your image from Photobucket will re-appear.
IF you are not the original Poster, but want to see an image somebody posted , but never updated (has the ERROR missing the image). (You cannot edit that post)
Hit (QUOTE). IN the Quote find the URL (IMG) in that POST you just quoted and do the same (add "~original"), and hit PREVIEW .
THe Image will show up.
You don't have to continue with the QUOTE and save it, just snag the image you want. (and cancel out of the QUOTE Reply)
