New Jarduino build gets started

[daplatapus]

Well, I finally broke down and have ordered most of the parts to build my own Arduino based controller based on the Jarduino. For starters this will control my DIY LED build, heaters, and skimmer and fuge lights. If I can get a few other relay's figured out I'll also include main return pump etc.
Also to dim my LED's I'm going to try and get a hold of those Meanwell LDD1000H drivers. If anyone knows where I can source some, can you please let me know? thanks.
Pics will come as I get the parts in the mail. So far have $112 invested

I ordered most everything too.... just waiting on everything to show.

The LDD-1000H's are hard to come by right now. Mouser has them in stock, but at twice the cost. The couple of other places I found either don't ship to Canada, or they only use UPS ($$$). Try "Octopart" it's great when trying to find electronic parts. I picked up 4 of the 600's where I got my power supply, but haven't had luck getting the 700's or 1000's yet. (out of stock) If you find a place.... let me know.

I also have a couple of the PCB's coming that hold 4 of the LDD's.

Sweet. Might be good to have someone to bounce ideas off of. I'm trying to get a hold of 4 of those boards too from a guy who has extra on RC.
I'm looking at getting some of those drivers from someplace I can't mention here. PM me if you need some and I can see if we can double up on an order if they're available.

Definitely sounds good.... I should have most of my things in the next week or two. Haven't decided if I want to go PWM for the fans or just use relays yet.

Don't know if you knew or not... but Modular LED had a sale on heatsinks.

I actually saw that about 2 hours after I ordered my stuff from somewhere else. Du'oh!

Definitely interested in 4 drivers. PM'd you!

Turns out a 18AWG wire all by itself in the open air can carry 10A but it's de-rated once it's bundled with a bunch of others. The ratio of decreased carrying capacity depends on how many wires it's run with. But according to our math 18AWG should be fine for what I'm doing. And as it turns out he had a roll of 18/21 sitting in his shop he gave me for $2/ft. It is fire alarm wiring.


And I also got some other goodies in the mail yesterday. Now all I have to do is figure out how it works

daplatapus,

Send me a close up digital picture of the header pins for input.

I just received mine last week but the 4 relay version. The relay modules are opto-iso which will require the pin to be tied to gnd to latch. From what I've found out over the last week, the opto-iso is not compatible with the Jarduino.

Simply put........the relay board latches on GND but eventually becomes inconsistent also latching on 3.3 to 5VDC.

Ya, I was actually just reading something about that on the jarduino thread on UKreefs. But I admit I'm not sure what all that means or what to look for for a proper relay board
Give me a sec and I'll post the pic.
