Slashdot Mirror
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?"
Just looking at this tonight: Horizon fuel cell's hydrogen r/c car kit and retrofit for larger models... http://www.horizonfuelcell.com/store/h2go.htm As a kid I loved building my own R/C cars, this would have been amazing to have!
Assuming sufficient and sufficiently geeky parental involvement, there are lots of cool things from United Nuclear. http://www.unitednuclear.com/
A collection of the smaller magnets and some ferrofluid are a pretty good combination. Ferrofluid has aproximatly the same danger and potential for mess as old engine oil, so depending on the kid you might need to supervise it. A variety of magnets also add variety to a ROMP set. http://scientificsonline.com/product.asp?eid=EID02&pn=3082172
You might also try throwing some mechanical puzzles at him. One that I particularly like can be found at http://stores.brilliantpuzzles.com/-strse-212/Internal-Combustion-Metal-Puzzle/Detail.bok but there are many.
When I was that age, which was about 10 years ago, I built my first computer. I was also tinkering with the infamous 'bread board' circuit test beds and random resistors and chips that I could get my hands on.
I would have loved to have a subscription to something so amazing as the Make Magazine at that time. It has some amazing bits in it about almost anything that I could ever have wanted to do or make. Besides that, it would have allowed me to find out about some crazier things to do in your own kitchen or garage to make something fun long before I would have played with it at school or college.
All in all, I can't recommend Make Magazine highly enough.
Communism will never work. People LIKE to own things.
it is a great way to get creative and it teaches basic programming skills
Model rockets are still pretty amazing, and pretty cheap. Just keep the engines until you're ready to use them. I would have killed for a radio controlled helicopter as a kid, and they're darned affordable these days.
For video games, Mindrover is still a programming and logic classic.
The ______ Agenda
Yeah, he already said that. Better answers include:
- Kids Electronics Lab
- Eyeclops Microscope
- Commodore 64
- Lego Mindstorms
Those are just a few toys that can be used educationally to learn about science, engineering, and math.
Javascript + Nintendo DSi = DSiCade
the very best mechanical- and engineering-oriented building sets are still Fischer Technik (sometimes spelled here with no space). Made in Germany for decades, and still being made with new kits updated all the time, Herr Fischer designed the best engineering building blocks on the market today. They are still being made, and are often used by universities for mechanical and computer engineering projects.
These kits make Lego Technics and Erector building sets -- even the new ones -- look like, well, child's play. But they are not cheap.
You can often find used Fischer Technik kits on ebay, some of them 30 years old, for sale at a good price. Even at 30, if they are not abused they are quite usable. (I know, because I bought some and use them.) Unlike some other building sets, there is no shortage of replacement or add-on parts.
There are sets that go from basic building, like bridges and little toy push cars, to electric motors and pneumatic controls (compressor, air tank, air pistons, etc.!), R/C vehicles, and all the way up to computer control with feedback. The main direct-buy sites in the U.S. are: http://www.fischertechnik.com/ and http://www.studica.com/Fischertechnik/ but don't forget to look on eBay.
You will not be disappointed by the quality.

When I was a kid I loved my 50-in-One Electronics Kit from Rat Shack. They still make some kits: Electronics Learning Lab although I don't know if a 13-year-old would care as much as a 10-year-old.
Here's their kit category: http://www.radioshack.com/family/index.jsp?categoryId=2032398
I see they have one that also includes a Basic Stamp. Or maybe it would better complement an Arduino.

I just clicked that link at work! You could have warned me at least!
The Mirage optical illusion is pretty amazing. I have it, and a Levitron, and while they're both really amazing for a while, there's not a lot of stuff to keep doing with them.
Those electronics kits from Radio Shack and other places with the resistors, diodes, etc and little springs and wires to use for breadboarding are pretty cool and educational. If he actually digs into those, it's pretty cheap to buy a real breadboard and a power supply and a bunch of real components and he can start making real stuff. If he graduates beyond the lessons in the book that comes with the electronics kit, pick him up a copy of Horowitz and Hill's The Art of Electronics, and let him get started with real stuff.
I think they're over your price range, but Lego Mindstorms are great.
You can always get him started with elementary computer programming. If "real" languages seem too challenging, HyperCard is great for starting programming, especially since pretty soon you start to find stuff you want to do but can't, and then find out that HyperTalk is a real programming language that you can start adding in piecemeal to your project, gradually learning programming.
If there are local scout troops, building and racing Pinewood Derby cars can be great if you get serious about going for either style or speed.
A basic model rocketry kit can be fun. It's cool to see it launch.
There are lots of cool science related toys/kits/gadgets here.
Can anyone tell me how to set my sig on Slashdot?
just consult this.
Want to improve your life? This guy will show you how!
How about:
- A subscription to Make magazine
- A chemistry kit
- A Velleman Electronics kit (he could build a pong game or whatever else catches his interest)
- A robot kit from Parallax.com
- Build a crystal radio with him. Even cooler, build one out of household junk.
- A Digicomp mechanical computer.
Heck, rather than me writing a long list, you should visit the DIY section on my site It should give you a few dozen good ideas. Just be sure to drop me a line if you actually build an ALTAIR 8800, tube amplifier or homebuilt ultralight, though.
If he doesn't have one yet. Preferably one with a proper locking blade.
This web site is perfect for inquisitive teens:

It's crazy cool. He shows you how to make your own working spectroscope with a box, a CD, two razor blades, and some tape!
The guy who put up that site has written some actual paper books, so you could give one or more of those. Or, just order some magnets and diffraction gratings and such for building the gadgets, from the catalog:
https://www.scitoyscatalog.com/
I really wish I could have had access to that web site when I was 13. Oh, well... at least I have access now!

Have you looked at a cold soldering iron? I find it a little annoying to work with, but I keep one in my woodshop, because one thing you don't want to have in a room filled with wood shavings is something with a temperature of over 500 degrees that takes more than a second to cool down. Might be just the thing for child. ThinkGeek stocks them.

I second the rifle motion. I'm still amazed at the differential equations that are involved with external ballistics. Did you know that scientists have yet to develop 'closed form' equations for bullet flight? They have excellent approximations, but the formulas rely on empirical measurements of the bullet flight to derive so-called 'ballistic coefficients' for different velocity subranges for each bullet weight and shape. Sierra Bullets has a wonderful section of the equations of flight in their reloading manual that they have released on the web. I recommend it highly to anyone with a mathematics background - check out the 4th edition information starting with section 6.0
