What's that, Aunt Ocherdraco? Why, nephew, it's a Phee!

My not quite two year old nephew is fascinated by lights. He calls them phee, which is adorable. I discovered today that he is so fascinated with them that he enjoyed watching me, via webcam, blink on and off the plain white led on my phone. I have a feeling that if I were to amass a small arsenal of brightly colored, differently blinking—dare I say it?—color-changing and/or blink-speed-coordinating lights, I would be favorite auntie for at least fifteen minutes at a go. (Which is a long time for a toddler!) My requirements within. [more inside]

Why aren't left turn signals "yields" rather than "stops"?

I have seen many controlled intersections that have one (or more) left turn lanes with one (or more) straight-through lanes with separate signals for the left turn lane(s) versus the straight lane(s). In general, those intersections are designed to have straight-through traffic going from two opposing directions and then alternate with left-turning traffic going from two opposing directions. When the straight-through traffic is passing, why do the left-turning lanes get a red circular light rather than a green circular light or a yellow circular light? [more inside]

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]

Help me un-SAD my bathroom

I recently moved. The only light in my bathroom is from five of these bulbs (with the smaller bases -- I don't know exactly what they're called) over the medicine cabinet. I'm wondering if there are nice, bright, LED (full spectrum?) SAD-fightin' bulbs, ideally with warm white light, that I could screw in in their place. Any additional brightness would be welcome to help my brain as I get ready for the day and the year gets darker (I have to get up very early for work). Thanks very much!

Lights on wind turbines - all in sync, but how?

The Biglow Canyon Wind Farm in Oregon, south of the Columbia River, has around 200 wind turbines operating. A while ago I drove past this installation at night time and I noticed that all the lights on top of the turbines - to indicate their presence to aircrafts, no doubt - were blinking in a totally synchronized manner. How is that possible? [more inside]

Weird question--How to light up inside of violin/viola?

Saw a video where the gal played a violin and there was a light inside, somehow--you could see the F-holes glowing. You can see it towards the end of the video. It wasn't CGI. My daughter plays the viola and thought that was really cool and wondered how she could do that and still make the light removable. Of course, it might alter the sound somewhat but she doesn't care as it wouldn't be permanent, (if it can be done at all.) Anyone have any ideas how to temporarily make the inside of a violin/viola light up without viola surgery and still be able to reverse it? Yeah, it's a weird question but doesn't hurt to ask.

How can I get my city to improve traffic signal timings?

I live in San Diego, and I hate the traffic lights along a particular road that I always drive on (Genesee Avenue). I'm regularly astonished at how soul-crushingly stupid they can be, and I'm constantly yelling at them from my car like an idiot. What can I do about this? My dream would be to talk to the traffic engineers in my city, really pick their brains and offer my observations. How does one go about making this happen? [more inside]
