The Ring (I'd use it more than a handgun lock) Printer Friendly Version
I saw a nifty safety lock for handguns on a tv program. The hand gun is equipped with some sort of locking mechanism which is unlocked by the presence of a magnetic ring which is worn by the owner. No ring, no discharge, no accidental shootings. Great idea, no doubt it'll save lives, make the world a safer place, etc. But what I could really use is a ring that would unlock, and start my car when I lose my keys, or prevent my car starting if someone tries to start it with out the ring.
Reward:

"The ring"

Non-GPS-based, computer interfaced, in home, cat tracker Printer Friendly Version
I saw the GPS-based doggy locator system post. Has anyone done this one? Use one or three (triangulation) in-home reciever/transmitters (maybe paintable, to blend into corners of ceiling) to track and record the exact location of your cat(s), while in the house (or any location in the range)? It seems like it wouldn't necessarily need a really high-power or sophisticated transmitter/receiver. . . I would've used this when we trained our second cat to use the toilet. She would occasionally use a few, favorite areas when she forgot about using the toilet. We didn't want to (but did) have to cover up or otherwise use physical blockades and clutter up our, already small, place.
The system would set off an audible command from a stereo (or shock on collar, or have small, portable, remote water squirt/sprayers, -whatever) when the pet is in a pre-programmed, discretely defined, off-limits areas. It could be linked to your PC and use a program that knows the boundaries of your home (area, whatever). You'd first take the collar around these boundaries of your place so the computer program could learn/outline the volume of range. Then you could go around and set "NO!" zones (our cats know what "NO!" and "Good Kitty" means). One could change the location and size of "NO!" zones from the computer, without moving obstacles. One could also record where the kitties have been while you are gone or where they are now, if they like to hide and sleep. It seems like having three, inexpensive reciever/transmitters would allow for realiability as well as pinpoint locating - to keep cats off vertically different surfaces like the counters, away from small "visited" spots on the carpet (cats can detect even well-cleaned areas), while allowing them freedom to roam anywhere else.
Reward: Joy of seeing a low-cost system developed and work, and maybe get a free one and/or whatever the developer sees as fair.

Website that teaches how to program Printer Friendly Version
How about a very interactive/fun website that teaches people how to program or make websites? Here's how it would work:
- Someone creates an account on the website. The account creation process would figure out where the person should go/start in the midst of all of these interactive tutorials. The same account could be used to add or edit existing tutorials (an approval system would be made). They can do as little as adding on a sentence to someone else's tutorial or create a flash application that would enhance how to create x with language y.
- There would be all kinds of interactive/fun tutorials ranging from HTML, Java, C++, web design, Photoshop, and so on. It would help people who think they don't have what it takes to make a good website or have what it takes to program. This will be the site's main purpose: to get more and more people better at this stuff seeing as how so many people are in need/desire of a website but in so many cases have to get other people to help them make it.
- There would be some kind of incentive to making tutorials or even going through the tutorials. That I don't know yet.
- The tutorials could contain mini games (whether they were simple text-based or bigger flash applications) that help introduce an idea or whatever.
Reward: I dunno.
