Okay i'm building one. Have more photos of your wiring?

 

 

 

Also, anyone having issues with the heating? mine seems to dip a few degrees over night into the mid-lower 70s.

Power cord on left: cut tip off charger cord exposing red and black wire.

 

Black wire goes to first connection on left in adapter (comes attached to dimmer), which equals v- on IN terminal.

 

Red wire goes to second connection correlating with v+ also on IN terminal

 

The wire on the right is taking the power to the leds, you have to drill a hole in the dimmer box for this wire

Thanks. Where does the driver get wired in? Do you have photos of the LEDS? Are you running all in series on the dimmer, or do you have some parallel outside of the dimmer?

Forgive my terrible soldering skills and explanations:

 here is a pic of wiring on the heat sink. The positive wire from power supply from dimmer connects to the positive on any led, then wire the leds in series until you get to the last led connecting the negative of the last led to the negative on power supply. It may look a little confusing in the photo because one of the stars has connected wiring and the other has separate wiring. Please note, I really think this many less looks nice but definitely over kill, 2 RB and 1 NW would be more than adequate

Thanks! so where does the driver fit in?

I have all leds in one series on the dimmer because... that’s all I know how to make 🤣

 

here you can see the blue wire from driver is connected to negative on cord connecting to led and yellow is positive

Here is the board flipped over. If you leave the adapter plugged in it’s easy to see where to solder the red and black wires from the driver. Yes, they connect to the IN terminal. The white wire connects to the right gate from this direction- note if you are looking at the board from the other way as when you will be soldering it’s the left gate. That connection is a pain in the rear and the hardest part of the whole project because that wire does not want to stick to that terminal! You basically need to get the solder underneath and all the way around that terminal before you try to attach the wire...

Thanks! I was thinking about a project box, but seems like everything just fits in the dimmer box! I gather what would be the Dimmer V out goes to the driver instead, so you rerouted internally.

 

edit: see the new post. Awesome!

So i'm having some

So I'm having a little trouble. The dimmer I received is a different layout than the one in your posts.

 

I've got it all wired in, except the white from the LED driver labelled "DIM"

 

I'm thinking it is where i circled in red, but holding the dim against this does not seem to work. maybe i just need to solder to get a better connection, but when testing with it held i just get 100% LED at all time.

 

 

 

EDIT: Think i may have it - think it was just a bad connection on the dim. seemed like i had ability to control (although a bit intermittent, to be expected becuase i was testing while holding the white dim wire in place and the out wires to the single connection LED. Going to solder that part up next - since blinding myself during the testing is making it difficult. Just adhered them this a.m., so assume it takes a bit for the thermal adhesive to cure. once it has and the leds stop dancing i'll wrap up this project.

 

Assuming I haven't destroyed the chip, it's a relatively clean little build:

 

 

 

 

Thanks for your help! I couldn't find hte smaller l series drivers, and think i ended up with an H, but made it fit.

Awesome! Love to see a fts when you’re done! I run mine at barely on and everything is doing great and it’s still super bright!

 

Glad the pics helped-when I reassembled the dimmer box after taking the pics the light was no longer dimming, just staying on at 100% which was way too much power. I bought a new dimmer to replace the 1st one and that corrected the issue

Very cool! I bought this dimmer also for a DIY light but other tanks have taken precedent for now.

Interesting. was your replacement the same PCB layout as what i posted?

 

 

 

 

 

 

- Yes i need to move it/add a drip loop.

Hi all,

 

I recently ordered a small pump on amazon to try and increase my flow in the tank. This one is essentially a drop in replacement. The original one is listed as being 0.5W on the Mini Complete website. This one goes as low as 1W. I also coupled the pump change with a "flow director" AKA some airline tubing and a suction cup. The little rubber fitting that comes with the tank fits directly on the nozzle of the pump. Figured I would share with everyone!

Hi everyone,

 

I'm new to this hobby, but I'd like to get one of these tanks. Can it be low maintenance for me to keep it at my work desk? If not, I can always keep it at home, but I'd like to have it at work if I can.

these suffer badly from salt creep and often have poor fitting between the tank and sump.
