Fun with LEDs

I want to start messing with LEDs; I have two (similar) projects in mind. I want a strip of multi-colored LEDs to respond to music. And second, inspired in part by this thread, I'm interested in learning about turning sound-responsive LEDs into a costume. I imagine those two projects are pretty similar, other than needing a portable power supply for the latter, right? So, can anyone help me figure out what I should get to start with? [more inside]

What light fixture is this?

Some enthusiastic home dance party moves caused me to shatter one of the glass lampshades on this light fixture. I'd like to replace the shade, but I have no idea what lamp's brand or model is. Do you? [more inside]

Curtain fabric for maximum light, minimum visibility?

Moving into a new apartment (yay!) with big windows, and I love me some sunlight. The problem is that the apartment is on the first floor and located in a pretty busy area where people will be walking and driving right by my windows a lot. Thus, I want curtains and I'd like to make them myself. My question: what fabric would allow the most light to enter the windows but also provide me with some decent privacy? [more inside]

Tell me where to buy / how to make a DC light timer

Our chickens [!] have trouble hopping up on their roost at dusk. We have glued a keychain LED to the inside of the coop and have been turning it on every night, and then off when they are roosting. I would like to have this turn on automatically at dusk and then off again an hour later. If this were AC I would buy a timer from the dollar store. For DC do I need to build something? [more inside]

How to Get More Light?

I recently moved into a new apartment on short notice. One thing I didn't realize when kicking the tires was that there is no natural light in my bedroom during the morning. This tends to make waking up an unpleasant and lengthy event—it's dark, and often I just fall asleep again. I don't want this to happen, and I've noticed that when I sleep in a room with good morning light exposure I wake up earlier and happier. So: how can I replicate a rising sun in my room? Full spectrum light (like for SAD) hooked up to a dimmer hooked up to a timer? Clever arrangements of mirrors?

For how much can I sell this stained-glass pendant light?

I know nothing about stained-glass, but I do know that at some point, someone spent hours making this and we're finally updating the room it's in, so it's time for it to go. Just wondering what I could reasonably sell it for, and if there are any good forums for doing so (other than Craigslist).

Has anyone heard of spontaneous remission for severe bouts of depression

I've struggled with depression for 30 years and have tried multiple medications/treatments, light therapy, Transcendental Meditation, etc. The last modality I had so much hope for was Transcranial Magnetic Stimulation; the treatments actually made my depression worse. Since we all know of cases where tumorous cancers have disappeared without explanation, I'm hoping someone has witnessed this occurring in a friend or loved one who's been diagnosed with clinical depression?

Will my room look nice if I illuminate it with LED strips?

I have a large room that I would like to illuminate with LEDs. I'm thinking of putting a ledge around the the walls about 45 cm / 18 inches from the ceiling and laying LED strip lights along it, directed upwards so they bounce off the walls and ceiling (which are painted white). Would this look weird? Would it light the room adequately? I'd make the ledge with a groove in the top surface so that you can't see the LED lights from floor level. [more inside]

What to do with friends during Seatac lay over?

We are relatively new to Seattle and have some friends who have a five hour layover coming in tomorrow afternoon. We do not have enough room in the car to carry them all, so they (1 father, 2 sons - ages 3 & 5) will jump on the light rail and meet us somewhere. Where would be a good, child-friendly place to meet along the light rail route to hang out for a few hours on what will likely be a rainy afternoon?

What do I call this lamp/light thing?

This is a light with a picture of some sort of presumably Italian religious icon.

Help me come up with a sassy quip in response to people's sexism.

I work in a small shop in a male dominated trade. I am 26 but read younger (by up to 10 years if you have a weird idea of how teenagers look) small, blonde, and need to dress casually (jeans and a tshirt and sneakers) due to the nature of my work. Customer's ask me on a near-daily basis if I'm my boss's daughter. I hate this, I feel it undermines my value as an employee who has worked hard to be in the position I'm in. I'd like to think of a response that makes them feel like a ninny for one second, without offending customers. [more inside]

Disagreement at work about best photography practices!

When shooting and preparing an image file for print, I've always tried to set things up so that the highlights are bright, the shadows are dark, and everything else is in the middle. At work, I've occasionally been told by my immediate superior that I'm overexposing my images, and that the highlight detail is, in their words, 'blown away'. Checking my files, the highlights in the images in question cut off around 245, sometimes as low as 240! Is there a reason why they'd want the highlights even greyer? [more inside]

What Did The Office Workers Of The 1600s Eat?

I always hear that the traditionally heavy US diet ( or any " traditional" cuisine, really ) was developed for people working long hard hours of manual labor, farm work, etc., so what did the people who had sedentary, less active jobs eat? What were the historical diets of people who didn't haul lumber through the woods or dig ditches, but recorded numbers or did accounting or translated documents?

Would an alien radio pick up a cacophony or a damp fizzle?

If an alien located on a planet 100 light years from here was to switch on a big, multi-frequency radio receiver, and record all the noises coming from outer space for the next hundred years, on all frequencies, how many soap operas, advertisements and new broadcasts would they pick up from Earth?

Over time, as the number of Earth transmissions increases exponentially, would the alien pick up a cacophony or a damp fizzle? [more inside]
