I put a bunch of strips under my kitchen cabinets to provide ambient light across the whole counter. It's all wired-in to the stove light switch. For the higher cabinets above the sink, I didn't want to see the exposed strips when I look up, so I have a long block of wood in front of them and they shine down from behind it.
Works very well.

Yes, you can fit a PCIe x16 card into a PCIe x4 slot. Some PCIe x4 slots even come without a "backstop" bit so you can do that.
You can either make it so the slot doesn't "stop" or cut off part of the GPU, or you could get a PCIe x4 -> PCIe x16 adapter cable, such as this: http://meitk.en.alibaba.com/product...iser_Card_Extender_Cable_Ribbon_Flexible.html

How about a PCIe 16x into a PCIe 1x slot?
http://www.youtube.com/watch?v=Dvxcnfx3Bm0
Just cut that sucker off and there you go!
But, can't you just cut the back out of the 4X slot and plug the 16X card in and it 'sometimes' work at a lower number of PCIe lanes (IIRC)?
As for LED light strips, just look at the ones that Big Ass Lights (same company as Big Ass Fans) uses. We built a tester for those guys so that they could count the number of LED's working on the strip and it took 4 - 5% window tint strips sandwiched between Lexan to get the intensity down low enough to view by the human eye. Bright mother 2#$@#$@#!

I've been toying with the idea of using LED strips instead of Christmas lights. RGB ones hooked up to a micro controller. Could have different profiles for different holidays or just different "animation" patterns. Though to take it a step further use bit shift registers to control each LED individually. That would be some serious custom work though and not sure how you'd weather proof that.
As for a 16x card into 1x, I think that actually DOES work!

He Ironwing, cut these down! :biggrin:

Watch the video. I've worked on programming those assembly lines (just changes, I didn't design or write the original program for them - although I did for the latest Big Ass Fan models).

Now I'm thinking about the instruction set for a ceiling fan.

LOL, if you saw what the current generation of 'high end' Big Ass Fans had in them, you would re-think that. We had to keep changing the tester because they kept changing the firmware of the fan (yes, everything in life including fans now have a firmware).
By the way, what happens to your code when the fan is put into reverse? And does it work differently in the Southern Hemisphere than it does in the Northern Hemisphere, just like the toilets? :hmm:

The fuck?! If they don't want it watched, why is it on their site?

I still get the same screen. I tried enabling all scripts, and enabled Flash. I'm guessing it wants 3rd party cookies. It isn't worth all that.

On a related topic: now that I've cut my LED bar down to size I'm left with a ~1ft of LED bar left over. I tested it and it lights up just fine with a 12V power supply. So I'm going to order a power supply and cut the plug off the end to wire it up. The question I have is "What kind of solder should I use to attach the wires off of the power supply to the circuit board. The solder points on the board appear to be copper plus some silvery looking metal, tin? What diameter solder should I buy? Should I buy rosin core? Also, I don't have a soldering iron so I was thinking about this one. Any recommendations there? I like the idea of having an iron I could use anywhere so that was why I picked butane.

Butane looks like a spendy expendable. An extension cord or inverter wouldn't work?

My soldering iron (electric, lxskllr was right) and power supply arrived yesterday. This morning I went to work. I even read the one page manual that came with the iron. It turns out the manufacturer had some sage advice. I now have two LED light strips up and running. I still have a small thee LED section left over but I'm not sure I'll do anything with it. It isn't worth the cost of another power supply but maybe I could daisy chain it off of the strip I just powered.
I don't know if you're trying to insinuate that this won't work. It will, and it will work just fine as long as you don't damage anything. PCIe negotiates the available number of lanes, and if they aren't present, it just uses what is.
As others have suggested, typically cutting off the back of the slot is what is chosen instead of cutting a board.
The opposite is also perfectly fine. Put a shorter PCIe card in any bigger PCIe slot.

Not at all. I know it works. I thought that Ironwing was insinuating that it wouldn't work by his comment and that's why I posted this one.
Like I said, you can also just cut the back of the slot (smaller number of lanes) out and fit the larger PCIe card into it and it will work fine.

I've done it using weatherproof WS2812B RGB individually addressable strips. I also connected an RTC (real time clock) so the lights turn on and off at set times. Works pretty good, and it's very easy. WS2812B has the addressable LED driver built into the LED. All you need is the strip (they come in 5 meter rolls but you can make it longer if you want, and can supply the power, the power supply and a microcontroller. No need for shift registers, the built in driver and microcontroller take care of all that. The microcontroller code is open source. I can give you my modified code with more effects that I coded if you choose to do it.

That before/after is crazy. What's the approx retail cost of one of those bad boys? Yeezus look at those heat sinks.

That sounds awesome, nice to know that there's a solution for this already. I'll definitely look into that when I do decide to do it.
Looks like the actual addressable LED units are buyable individually too. Imagine the possibilities if you do a matrix along the fascia. :biggrin: I'm guessing these have a unique address almost like a MAC address and work similar to "1 wire" sensors?

My work place recently installed a few lights similar to these and they were 300 bucks a pop. They look fairly similar to regular fluorescent light fixtures except instead of having two bulbs in them they have an array of white LEDs. They're actually pretty nice. I bet they only use like 5w per unit though so in the long run you save especially in a commercial environment where they may possibly be on 24/7.
They also make neon tube retro fit bulbs that are LEDs. I never saw them in action myself though. LED truly is a great technology.

I hate LED strips... the ones I run into rarely have a diffuser (like just translucent tubing) and end up blinding me. Cafeteria at my old job had strips around the perimeter of the drink fridge. Accidentally look at it and I get a nice retina burn-in for about a minute.

Oh yeah they really need to have a diffuser. That is something I'd want to ensure if I do any kind of LED strip stuff for outside the house.
It's like those car HID lights, those things are ridiculously wrong. They should be illegal. It's like staring at a non diffused ultra bright LED except it's that bright at all angles. Seeing those lights more and more now too. I almost want to install a sensor on my car that detects those and fires a burst of microwaves to kill the bulb. Actually, if I knew how to do that, hell yeah I'd do it! That would be hard to detect too.
