Chasing circle of LEDS...?

I'm in the process of making a UFO model for the local Railroad museum's model trainset.  What I want to do is have the standard disc shaped UFO with embedded LEDs on the edge.  I would like the LEDs to chase around the edge repeatedly while the display is on.  I've looked into using Arduino, but size is a factor.  The UFO is going to be about 6" across.  As far as I can tell, I can use a 555 and 4017 to work it out, as but that limits me to 10 leds, right?   If it can be worked out, having counter rotating circles would be great... But that would be duplicating the circuit and reversing the 4017 pin outs... AND...where is a good place to buy small quantities of LEDs and ICs?  My local Radio Shack has nothing in stock

What's the right dremel bit for a circle jig cutter? I had problems with this.

Hi, i just made a circle jig cutter for my dremel. I used the included dremel that you can see in the picture below, it basically looks like a drill bit, but it's sharp in the edges, so it can cut to the sides, thing that drill bits cannot do. I tried to cut 3/4 MDF, but it was very hard to do it, I simply had to stop the process after concluding that that's not the right bit for that job. I think I had problems because this bit is for cutting to drywall sheets instead. What do you think? does anybody know what dremel bit should I use to cut circles through 3/4 MDF? thanks.

The world has come full circle

Every once in a while I'll come across some piece of furniture in the store that's modern. I'll look at it and say: "Hey, that's kinda like the sixties." Well... I wnet to Houston TX a while back and saw a neighborhood of modern homes. I looked at them and thought: "Hey those remind me of old" I Got to thinking about and realized "Oh my gosh! We're living the sixties all over again!" I mean seriously! Take a look around! All these "Modern" things aren't modern at all. They've all been thought up before, but it was 40 years ago so the newer generations thinking it up don't realize it. Below I've put some pictures. The first 3 of 1960s homes and the last 3 of Modern homes. See the similarities?

A Mystery: Why Can't We Walk Straight? from NPR on Vimeo. Try as you might, you can't walk in a straight line without a visible guide point, like the Sun or a star. You might think you're walking straight, but as NPR's Robert Krulwich reports, a map of your route would reveal you are doomed to walk in circles.

Bacteria-like projections when shining a laser through a magnifying glass.?

          I was recently shining my new green laser pointer through a magnifying glass, and the beam went through the little circle near the bottom of the lens that magnifies things more than the rest of the lens. The laser dot got very much larger, and there were odd little dark circles surrounded by larger, transparent circles. I also noticed the same thing, but with longer, oval-like projections instead of circles. What are these projections of? I'm guessing dirt, hair, bacteria, etc. Can anyone tell me? I want to know because it's a pretty cool effect and it would be cool to know if I'm looking at bacteria or something like that.

Electronics Plastic housing

I have a plastic housing for a VCR with some molded-in markings on the inside. *There is a circle with an arrow inside and two numbers outside. "1207" & "1208" The arrow is pointing to "1207" *There is a circle with an arrow inside and the numbers 0-9 on the outside. The arrow is pointing to "4" *There is a circle with an arrow inside and the numbers 0-3 on the outside. The arrow is pointing to "0" *There is a circle with an arrow inside and the letters A-H on the outside. The arrow is pointing to "B" *There are also two charts that has letters on the left and what looks like names of pigment colors on the right column. Some of the right side fields are blank. *There is another chart with "00", "99", and "98" on the y-axis and the numbers 1-9, 0, and the letters "N" and "D" on the x-axis. There are two markings - one at the intersection of "99" and "1" and another at "99" and "2". Does anybody know what these markings mean? I've seen similar markings on other bits of plastic electronic housing. I imagine that they explain the material that the housing is made of , but what do they mean? Anybody know? Have any ideas?
