Build It
Attach a tiny signaling device to things you often misplace, and you'll be able to recover them in a snap

That darn eyeglass case is nowhere to be found! Pachoumis.com

So you've lost your eyeglass case. Yes, again. Gets frustrating, doesn't it? Stop wasting time searching for stuff -- build a device that emits signals you can see and hear, so you can find what you're looking for instantly. Attach remote-control car receivers to any items you frequently misplace, and put the cars' transmitters in a control box that can activate the receivers' lights and sound signals. Then when one of the items goes missing, press the corresponding button on the box, and you'll have it back in no time. Or at least until the next time you need it.

"Container (we used RadioShack #270-1803; $3.69)"

I'm going to pretend I didn't read that.

It looked simple and challenging, since I am old, and I cannot find the 2 - Zip Zaps micro RC cars w/diff frequencies. I think I understand the directions but need the final element. Everything else is here. Radio Shack does not carry that part # anymore and 2 same freq @ 20 ea. Help
Thanks

So what happens when I lose the controller?

I won't have to worry about losing it since I can not find the Zip Zap remotes. Need suggestions, please.
Since I have all the components except the remotes maybe someone would buy them?

Can't wait to build one!

Also, I visit Radio Shack all the time and I haven't seen any ZipZaps for over a year. The link says their out of stock; I recommend trying Dollar General or Dollar Tree. They usually have the same size r/c car for about 2-5 dollars. Beware: some are not 'true' r/c cars...

simple..engineer a charger for your remote and install a buzzer on your remote..not only can you find your lost items, you can find your remote as well from your stationary charger.. or...

You could work on your mnemonic ability >.>

This has become a career since I can not find the RC cars, called zip zap, or similar.
I have been to Kmart, Walmart, Toys r us and Target. Talked to hobby stores, NKOK, as well as other such as Etoys and Dollar Tree - nada. I perservere but no info is available to help. You guys find everything simple because you understand the verbage. If you can assist I'm open for suggestions. If not where can I send the many parts I have ready, all except the two zipzaps w/different frequencies: 27 and 40 MHz.
Popsci is a great mag and I thought (?) I could really try something......... The worst part is nobody knows what the heck I'm talking about. I'm reading from the instructions.............

dont fret! a quick good search of micro rc cars and this is the first link i found. if you buy a two or three pack they even have different freq's

whoops! i meant google. my bad.

I am still looking for the RC. If I knew the specifics and where to order it would help. The directions and all the other parts are waiting. It could be my Xmas gift.
:(

You can buy the cars on ebay...remember you need a complete set of a car and remote for each item you want to track, and each set must be a different frequency. Don't make a mistake and just buy an "Upgrade" or "Body" kit with no car or remote control.

However, you could use only one remote control on one frequency and have multiple "ZipZap" receivers all go off at the same time when you need to find any of the remotes.

Alternatively, tie a knot in your handkerchief for each item you want to remember.
