probably just any old small capacitor and resistor you have lying around would suffice,
Got a AA batery LED tester lying around? Should light them up without flicker, till the batteries start to drain. Would tell you if it's a connection or the 5 volt charger at least...... anything over 3 volts should work.
Really, I mean really? Seriously, I have not seen a capacitor or resistor since my freshman shop class 35 years ago. I certainly don't have one lying around the house! I warned everyone here that this was going to be an adventure. :lolspin:
Got an old cordless phone that you aren't using? Lots of parts there.![]()
See my previous post. LOL I'm going to change phone chargers and see if that fixes if. I have enough laying around.
I'd bring/mail you one but the gas/stamp would cost more than if you just stopped at the nearest radio shack :lolspin:
Don't forget about that old VCR in the closet. I'ts chock full of parts to steal![]()
Try having the power supply unplugged from the wall, and the 5V. Make all connections, and then plug into wall and add the 5v last.
Maybe the magic fairies inside the LDD's are wigging out adding another channel when one channel is already on?
Where are the wire nuts being used and why? I don't have any is why I am asking. I look at those things as a weak point.

On the top of the board, pins 1,2,3,4, and 5 should be PWM positive inputs. The positive wire from your charger goes into pins 1 and 2. The ground is common from what I understand, and can go into any of pins 6, or 7.
The positive and negative from the power supply should be in pins 8 and 9. (8 as ground, 9 as positive.)

WooHoo!!!! That is VERY cool! I am sure that you will be pleased when you get them on the tank, the 4 I added made a substation contribution to the color of my tank.![]()


Looks like a good fit. That will allow you to angle them as needed, try it without the reflectors first, if they need to be added, it is just a piece of double sticky tape.
I am glad that you completed it, there is a sense of accomplishment and pride. Now that you have done this, there are MANY more to do. Ca Reactors, Kalk Stirrers... The list goes on.
I am talking with Melev now, to get a small footprint, dual container acrylic box made. Once I have that, I'll mod away to make a Ca reactor on one side, and a Kalk reactor on the other.![]()
I'm also looking at Violet LEDs, I think I can fit a couple on each of my heatsinks, that should add even more pop with very little effort.
