Introduction: EASY PARTY BIKE
Ever want to listen to music while you bike, not using boring headphones? How about taking music to outdoor parties without having to lug a set of speakers around? This is a super-easy way to listen to music while you bike...
PLEASE: Post your ideas to add on to this in the comments section, for everybody else, and me, to do. There's never too much music or speakers to blast while biking!
Step 1: THE INFAMOUS PARTS LIST
What You Need:
A cheap mp3 player, it will be alot easier if it takes a disposable battery...
A ton of duct tape
An old speaker... I used a speaker from a broken amp
Some batteries, the bigger (D) the better
A speaker cable
NOTE: You're mp3 player might break, thats why the cheaper the better...
Step 2: WHAT TO DO
Alright, now let's say you have all those parts... The first thing to do is to cut one of the heads off your speaker cable. A headphone cable would work better because it is already separated. Make sure the wire will conduct electricity. My cable had 3 small copper wires, each coated in a finish that I had to sand off. The colors I had were red, blue, and copper. If you somehow end up with one like that, don't bother sanding off the copper one, you wont use it, and it may not have a coating if you do decide to modify this idea.
Now, take your speaker and connect the stripped wire to it, and plug the other end of the cable into a computer headphone jack. Switch the wires around to the opposite sides and see which sounds better. Once you have decided the better sounding way, solder or just tape them together.
Step 3: HACKIFY ME, CAP'N!
Alright, now the fun part. I am not liable if you end up frying your mp3 player, but all I know is that mine did not die on me. Since I used a sandisk sansa e130, shown in step 1, it takes one AAA battery. That didn't seem to last long powering a small fender guitar amp speaker, so i figured this easy step out.
Let's say you have something like my mp3 player. It can take a AAA, AA, C, D, two of each, anything works as long as it takes that battery. If you have a rechargeable battery, I can't really help you, but maybe you got lucky and it takes an even voltage that you can make from a few batteries. Now, take the largest battery(s) you can find, as long as they are 1.5 volts, and depending on how many batteries your mp3 player takes, hook them up in parallel, or if you have one, just tape two wires to it, one on each side. I used a C battery because I had nothing bigger. Now, either solder or tape the other ends of the wire into the corrects part of the battery holder. (Positive on the battery goes where it normally would, only with wires) Make sure they are secure...
Step 4: TAPING
Nows the easy part... Tape everything! I taped my speaker to the bar across the bar, over the break lines. The brakes still worked, and so did the gear shifting. I would suggest taping it there because at least on my bike, the sound is pointed right at my head. I taped my mp3 player on the handle bars for easy aces, and the battery a little to the right (in the picture left, my camera reverses the images) so it could be changed easily.
Step 5: GOOD LUCK!
Haha alright good luck with this, it worked for me, hopefully you are as lucky as I am.
Like I said before, PLEASE POST IDEAS OR INSTRUCTIONS! I know there are better ideas out there, this is just a starter. Hopefully it will get people thinking about better ideas, and then those people can post their ideas here. If you make an instructable like this, post a link, or if you just have a cool idea please post it! Post some pics of my idea, or better yet your idea to give people ideas.
