Magic LED Box

On Sunday I was bored, so I built a box with some LEDs and mirrors inside of it:

Box Pic 1

It has blinking LEDs on the ceiling and a couple of convex mirrors on the bottom which reflect the LEDs and make it look like there are more than there really are.

Since it's dark inside the box, the blinking LEDs distract you from noticing the water nozzle in the middle hooked up to a squeeze-ball behind the box. When I activate the squeeze-ball it squirts you in the face:

I brought it to work and had moderate success showing it to co-workers. Many were initially suspicious of the weird-looking box, but I was eventually able to prank everybody that came by (except one guy who recently had an eye operation that I decided not to squirt).

It turned into a sort of a social experiment in how to get people to stick their faces into a box. I had some interesting observations:

  • People were much more suspicious if I said "hey, come look into my magic box" "what's in it?" "oh, you'll see.."
  • Instead, if I waited until they walked by and asked about the box they were much more gullible, especially if I said something like "oh, do you want to see the LED light show too? ok, let me turn it on..."
  • Everybody was expecting to get an electric shock when they looked in (probably because of the circuits and LEDs on the top). Nobody guessed that it would squirt water
  • It's probably a good idea to ask people if they wear contacts before squirting them in the face with water (of course that would ruin the surprise in this case..)

Here's a video clip with some highlights. I got a bunch of other people too but forgot to turn on the webcam in time:

Cereal Bugs

Don't you hate it when you find out that your cereal is full of dead bugs only when you're halfway through the last bowl of the box?

Weird Google searches

So, after 3 months of running Google Analytics I've had 1174 visits and 2050 page views for a total of 1.75 pages/visit (this doesn't count RSS hits).

The things I find most interesting are the 497 different Google queries that have led people to my site.  It's good to see that my name and variations on it are the top hits, but there's quite a "Long Tail" of other random Google searches.  Most of them have something to do with my previous posts, but some of them are completely random queries that happened to hit words from multiple different posts (and comments).  Here are some of my favorites:

  • defeating evil genies
  • sugar momma w4m
  • how to build knd weapon
  • lego store in stanford mall
  • how to build a lego ipod case
  • pcb designer blog
  • most difficult lego kit
  • faller car system video
  • fixing jetta airbags
  • loyalty and membership card programming

Here's the full list: link

Eames lounge chair

eames-chair-2.jpg

This is the "Eames classic" lounge chair. Introduced in the 50's, it's become a bit of a bit of an icon of American modern(ist) furniture design. It's featured in NY's Museum of Modern Art, and more notably (for some generations) it was a centerpiece in Frasier Crane's apartment. If you've seen one of my shirts, you know I want one:

The only problem is that it's a designer chair sold by Herman Miller, so it's naturally quite expensive. I've always been unable to convince myself to buy one, afraid of it becoming my own personal Rubicon on the way to a life of lavish decadence. Do I really want to become a person who spends $2000 on a designer chair? Perhaps that's the wrong way to think about it though: I don't necessarily want to become that kind of person, but I do want to have a nice, comfortable chair. Where does one draw the line between appreciation for the finer things and conspicuous consumption? I'm not exactly sure..

Right now I have an IKEA Poäng, which has become increasingly uncomfortable with its velcro-on polyester pad and rigid wooden armrests, especially for long periods of reading. So I've been giving the Eames some thought again recently, considering I might have some bonus money left after paying off my car loan (something I was planning to do a long time ago, but I kept buying too many toys). It's very tempting. Must.. resist..

I envy you Eddy. The only questions on your mind are, Who's going to walk me? Who's going to feed me?

Splat Monster

It looks like the eyes were probably painted on by somebody, but if not, how cool would that have been if this splat monster had just formed randomly?

Hot air balloon flyover

So I'm sitting here and a huge hot air balloon flies right over my apartment, really low to the ground. By the time I got my camera out it was a ways away, so it looks small in the picture. It was a lot bigger when it was right over me:

Now I have this strange urge to take a hot air balloon ride (something I've never done). It probably costs a lot, so I need some other people. Anybody else want to go on a hot air balloon ride?? Let me know.

Fun with pivot tables and match.com

I recently considered signing up at an internet dating site, just to see what was available. Naturally I was quite skeptical (since I am not divorced with kids and over 40). Match.com claims to have the largest number of members of any dating site, so I checked it out first. Fortunately, match.com allows anonymous non-members to do very extensive searching of their catalogue without signing up.

I started off with a basic search: women aged 20-27 within 25 miles of my zip code (this includes most of the Seattle metropolitan area). I drilled down from there based on various factors such as education, income, religion, etc... After I had collected a good amount of data, I dumped it into Excel and analyzed it. Using pivot tables I could see how various factors affected the number of potential matches. For example, here is a plot of the 'Income' and 'Education' factors:

Income vs Education

There aren't too many surprises here: more education correlates to a higher average income, but not that much higher. Other plots such as Age vs Income or Religion vs Education didn't reveal too many surprises either.

The real surprises came in the magnitude of the numbers of matches. For my search of single women aged 20-27 in Seattle, there were only 530 results. 530! Clearly there are many more than 530 single girls in Seattle, so match.com's selection seems to really suck.

Out of those 530 results, if I restricted the search to include only matches whose Education and Income buckets matched or exceeded my own, there were only 7 results (though there were 64 if I also included one income bucket below mine).

I know for a fact that there are way more than 7 girls in all of Seattle with comparable income and education levels, so one thing is clear: they aren't using match.com.

I don't think I will either.

SD vs HD

Fortunately, my problems with the video quality of the DCT-3412 cable box ended up not being so bad, for the simple reason that all of the channels I receive seem to be digital, so they can all be recorded via Firewire (as long as they are not protected with DRM). Also, connecting the MCE via S-Video instead of the RF tuner increased the video quality for shows I can't record with Firewire.

Once that was all working, I did some tests to see how noticeable the difference between SD and HD really is. Here are some pictures:

Obviously the HD screenshot has been shrunk to SD, so they look about the same here (except that the HD shot is in 16:9). Click the HD thumbnail to see it in its full resolution (HD 1080i).

Here are the two shots scaled to the same size, for an easier comparison:

The last shot clearly shows HD's better picture quality, but ironically the newscaster actually looks a bit better and younger in the SD shot, since the blurriness of SD masks wrinkles and imperfections, while HD hides nothing. (I'm definitely not the first to note this irony)

Fast pictures

After my previous post I realized that I forgot to include pictures of the 'fast', which is (arguably) one of the best features of the GTI.

Volkswagen ads claim "A 'fast' comes standard on every GTI," so when I got the car I was expecting the fast to come inside of it. Needless to say, I was disappointed to learn that I would get it in the mail in "4 to 6 weeks". Luckily I got mine a bit 'fast'er than that. Here is a picture:

Fast

It's made of very shiny plastic, which seems to be different from the more matte-looking material used in the TV ads. Its arms and legs rotate and it has a set of interchangeable tails:

Fast Tails

Overall it's pretty cool. Every car should come with tiny plastic representation of its Freudian id. 🙂
