I bought some lights from Home Depot and I've been really pleased with them. They were the cheapest I could find, and so far so good.

http://www.homedepot.com/p/t/204393679?storeId=10051&langId=-1&catalogId=10053&productId=204393679&R=204393679

I'm not sure if they fade well, but they flash on/off perfectly with no delay issues, and they're dirt-cheap. I needed 16 strings of lights and I got these for around $30 instead of the $100+ that I was looking at with LEDs.

Highly recommended!
Bring a touch of holiday cheer to your home with a set of Home Accents Holiday 100-Light Clear Mini Lights. Great for decorating trees, rooflines, fences and other structures, indoors and outdoors. For your convenience, connect up to 5 sets end to end for an extra large display on only one outlet plug.

I picked up a few sets of these from Lowes (Not Home Depot) this year. out of the 9 strands I bought I already have 2 that only light half way. Have you had this issue with any of yours. I can't figure out the problem, I have taken a light keeper pro to them and still can't find the failed spot in them. Maybe I just got a bad batch... I have a total of 2000 stung up on my windows (400 per window (2 green 2 red)) and out of them all half are faulty.

I have about 30'ish more photos coming, but here's my setup so far. I put it all inside an old soda bottle crate that my wife got for me at an antique store.

Lots and lots of photos of my build. I liked using the large crate to have plenty of space to work.

Yeah, it's definitely not water tight or weatherized. My plan is to watch the forecast and bring it in on any days where rain is a possibility.

And like an idiot, I catch the 3.5mm cord on my foot, ripping the input jack right off the r-pi.

Time to find a way to add some stress relief for that cable. And time to order another pi...

Stupid, stupid, stupid...

Always worth it to have another pi laying around :)

I'm almost done with the hardware setup, and it's time for me to order my lights. I was planning on getting 16 light strips and hanging them vertically on my front porch, mirrored on either side. So, assuming 3 channels, like this:

1 2 3     3 2 1


I actually have the default 8 channels, all wired up through the SainSmart 8 channel SSR.

Is there anything in particular to be aware of with the lights? Do I need LEDs or will the store-bought "regular" bulbs work? Are there any brands that are preferred? Stuff to avoid?

I see some LED strips that come with built-in controllers for different modes, and I'm worried those will interfere with just letting the power on/off control everything.

Any advice on which lights to buy would be appreciated!

I've experimented with a few varieties of lights and how well they work with pwm fading in particular.  Take a look at this video here for more details:

https://plus.google.com/102015744723309264957/posts/9D6koAM74ex

Main take-away I have at this point from my experience is that when plugging lights in at your normal house voltage (i.e. 120V AC in the U.S.), the incandescents tend to fade nicer with pwm - while the led light strands typically have a transformer or rectifier that makes pwm fade simply not work (looks more like flickering than fade).  That said - you can change those to be on-off mode and the leds still look great.

So I guess the only real points I have to make are:

* Ensure each you don't overload your output relays (if using the SSR's on the sainsmart board, that limit is 2 amps per channel)
* Incandescents fade better than leds if you are switching AC voltage via SSRs / Relays (I'd like to work up a better hardware solution for leds to get around this - haven't had the time yet)
* Be creative - we'd love to hear what you experiment with and get working - let us know so we can all benefit! :-)

Very helpful, and not pushy. They let us browse at our own rate and then were helpful with answers when we had questions. My wife and I bought BCDs and some gear and are very happy!

I've been going here for a few years, and I've always liked it. Then they added 4 squat racks and it became perfect. Can't say enough good things about this place.
