Anything cool to do with old car batteries??

[IminDiegoTriick]

Lmao some of these suggestions are just ridiculous!! aha.

hey that energy storage one is a good idear. now we need to build you a space heater with enough btus to heat the garage efficiently without killing the batteries in minutes.

NOW WE'RE ON TO SOMETHING.

I'd be so pissed to catch a phone book at 80mph. A battery wouldn't bother me so much because I'd be DEAD.

[Hey_You]

Get a large flat sheet of metal and get 10 cans of your favorite colors at Walmart for $1 each. Use .22 and put a hole or 2 in every can sitting on metal. Put battery on top of metal once paint has dried, 50 yards...sight in your .22, 100 yards, sight in your larger caliber weapon. When done, remove battery, wash down metal with water, clear it, sell it for a rediculous amount as art.

Use it to power a hair dryer. Put the hair dryer on cold. Attach to e30 intake. Enjoy intercooled supercharger.

1) Use them to sit on while you make a PVC rollcage

2) Stack them in your bed so it looks like you're under the blanket. Meanwhile, go have fun and pass out drunk with three mexican whores. This is cooler if you have a wife/fiance.

3) Use them as jack stands afterwards

Battery in a microwave

[Sagaris]

When I was in High School I got kicked out of my English class for being a jackass (loads of stories about that one) and they put me in a sewing class. I made a cheap blue bag in that sewing class and had no idea what to do with it. It looked like the perfect size to house a car battery. So thats what I did! I had an 87 Jetta GLi parts car so I took the battery from it, put it in the bag, along with the horn from the Jetta, a receiver+servo from an R/C glider I never finished building, and had myself a remote controlled car horn in an inconspicuous blue bag.

Initially the plan was to stick the "hornybag" or whatever you could call it next to my parents bed and wait til about 3am to switch on the remote and get a reaction out of them. That never worked since they heard a car horn blaring from my bedroom while I was building it and accidentally triggered it off and walked in to my bedroom and interrogated me as to why I was doing what I was doing. So anyways my friends and I had a good time with it. We dropped it off in the bushes at Wendys right next to the drive-through order sign and sat in my friends car (Schwarz 1989 325is w/ some ACS goodies btw, I was still stuck in the VW scene at that time unfortunately) in the parking lot and as people pulled up to order.....
Wendys:"Hi can I take your order?"
Customer:" Yeah uh, can I get a.." BEEEEEEEEEEEEEEEEEEP!
BEEEEEEEEEEEEEEEEEEP!
Customer:" A number.." BEEEEEEEEEEEEP!

Nothing showed up on their ordering screen since their order was drowned out by the sound of some random car horn right next to the mic. They were asked to pull forward to complete their order :P

While waiting for the next victim, two Wendy's employees came outside , one of them, a Mexican guy, reached in the bushes and pulled the bag out , placed it on the sidewalk and carefully unzipped it. The employees peered into the bag cautiously to see a car battery along with a mess of wires, duct tape, electrical tape, and some electronic components. The Mexican guy got his face closer to the bag to get a better look inside BEEEEEEEEEEEEEEEEP!!!! He jumped back and ran straight inside with the other employee. We figured they must have thought it was some sort of bomb or something. I passed the remote off to my friend, and ran inside the Wendy's to explain to them that it was just a prank that I had put together and not to be alarmed or anything. Well as soon as I walked in the Mexican employee was on the phone with 911 and speaking frantically. So I did one of these:


didn't say a word, ran and grabbed the bag, which was still sitting on the sidewalk, and we got out of there.

My friends borrowed the horn in a bag one day while I was at work and ended up pissing someone off enough to get the cops called on them and that was the end of my battery, my bag, my horn, and my R/C radio system. We had a lot of fun with it and pissed a lot of people off while it was alive though.

^ hahaha dude you are awesome. I wish school was still like this :(

So it was a servo? because servos move things with linear motion, not just on/off

[Sagaris]

It was very crude, as the servo rotated it closed a switch to complete the circuit for the horn to sound.
