Looking nice!

2 questions
- how do you seal the solderingpoints
- how do you 'glue' those strips to the coro? what type of adhesive?

1: Silicone
2: The strips come with a sticky back. When I silicone the ends, it will help hold the strips in place.

Took a lot longer than I was expecting to solder all of the connections. I tested it, and everything works! :thup2:

Another 'gotcha', the outline of the face uses 700mA, so I'm going to have to break it up so my Simple Ren32 can power it.

I thought about using strips but you can't drive them higher that 12V for most of the strips. There are a few 24V but the cut distance causes issues. That's why I wired Flat Top LEDs in series and run them at 48V. I can run a complete HolidayCoro pumpkin at 0.8A or less depending on the color mix.

8 Channel
The corro is 40"x 36"

My house isn't far from the street, so I'm hoping this will work. If not, I'll just stick it in the yard somewhere.

You've put a lot of work into that! Nice job. Hope it gives you the effect you're looking for -- have a GREAT Halloween!

Crappy cell phone video. Looks good in person, size is perfect for sitting above my garage door. It's really bright, lights up my drive way...

Total spent:
Two 5m rolls of 60 LED's/m Strips 3528 Warm White $22 shipped from eshopstar on eBay
Half a sheet of Corro from Home Depot $6
Other misc, wire, silicone < $5

Total hours spent working on it, priceless.

So for less the $30, turned out alright. It's powered by my Simple Ren 32 RGBW (12V). Uses 9 Channels. Supposed to be 8, but I had to split up the face outline due to current draw.

Ok, I'm really new to this but I am very impressed how good that looks for the minimal cost. How it it that the single spaced LEDs look like one continuous light? Are you shining them through a diffusing material? Could you give me a quick run-down on the construction?

Thanks
Ernie
