Gadgets For a Budding Geek?
fprintf writes "As much as I hate to admit it, it looks like my 13-year-old son is following in my footsteps and preferring interesting, science-based toys. In the past he has been really interested in Lava Lamps, Newton's Cradle, and anything magnetic. It seems the knick-knacks that have generated the most interest were small and relatively inexpensive. For example, a small laser pointer keychain I bought him a couple of years ago still provides tons of entertainment. Yesterday I showed him ThinkGeek and he really liked the Levitron. I wanted to ask the Slashdot crowd what were some other really neat, interesting gadgets? Is there anything cool in the under-$50 range that you would like in your stocking this year?"

Why do you hate to admit it?

As I write this the ad under this topic is for the Dungeons and Dragons Starter Set.
I think that should settle it.

There is a cluster of 7 year old siblings and cousins in my family, both boys and girls. I'd love to start a subtopic here on Christmas geek gifts available for this age group. One example: my son is asking for a Rock Polisher.
Seems to me like you can do an awful lot with the Arduino platform. I recommend buying from the Make guys, as you'll also see that they've published a book recently with the Arduino developers/creators that maybe your kid would like as a follow-on? They are only $30.00 and the only requirement is a computer to plug the thing into for programming. I'm asking my wife for one :-).

I don't want to say the s-word, but after I bought something from ThinkGeek, they started sending me marketing emails. I don't recall being presented with a choice about whether to opt in or out of marketing emails when I made the purchase. It was UCE (unsolicited commercial email), but you could argue that I had already established a commercial relationship with them. All I can say is that personally, if I buy from an online retailer and then they send me ads via email, my personal decision is not to do business with that retailer again. One very practical reason is that once they send me ads, I'm going to blacklist them in my email filter, and that would make it difficult to do business again. I'm not accusing ThinkGeek of being evil criminals with handlebar moustaches or anything, but it's just like any other business -- if I don't find it pleasant to buy from them, then they've lost my business.
Find free books.
seriously. it's how I learned that kinetic energy varies directly to 1/2 the mass and to the square of the velocity.
and how rabbits deal with sucking chest wounds and uncompensated hypovolemic shock.
dealing with sights and optics taught me about angles in degrees and minutes-of-angle and how they work with customay measurements and created triangles of horizontal trajectories. (there's mils for the same thing in metric).
dealing with virticle trajectory taught me about objects falling toward the center of the earth at 1/2 gravity x (time squared) no matter how fast they are going. and how quadrant is measured to compensate for various co-efficient's of drag and velocities/grains of bullets.
plus all the responsibility, maintenance, cleaning, and stuff. it was probably the best thing I got at 13. it sparked my interest in science and showed me how physics and math is integral in EVERYTHING you do.

A microscope was my most beloved science toy when I was young. The low cost ones aren't lab-grade, but they work.
At age 13, the kid is starting to get old enough to do more than just play with gizmos - maybe it's time to start making them? I was building radio-shack springboard circuits when I was younger than that. Maybe an Arduino board would be appropriate - nobody has to know how to program to use it because there are lots of projects online, but it's a great way to get started tinkering with a hands-on implementation of code! I have a boarduino from Lady Ada. It's only about $25, that should leave you some extra $$ to spend on a breadboard, wire and maybe some other parts.
2. Dowels--- that fit in the pegs..
3. magnets-- get a 25 or 50 pack of small magnets (consider a few with dowel sized holes).
4. mirrors-- minature... harvest a disco ball.
5. string--
6. DC motors.. the dinky cheap kind that come in cheap toys.
7. prisms.. small is fine.. get geometric shapes triangles-- squares.
8. cheap speakers.. harvest a junk clock radio or 8.
9. glue
10 small springs.
Anyway.. with the laser in hand you can do a bunch of stuff with this setup.. Laser-> mirror mounted on spring mounted on speaker will make a neat wall pattern.. then try without spring.
Make a magnet spring-- shock absorber by repelling magnets down a dowel..
Recombine laser light after splitting it with a prism.
Cover the dowels with slurpee straws. and make a pully system.
This rig is expandable, cheap, and involving enough that I'd play with it..
