Picture of DIY Bike Stereo
Want to listen to music while on a bike outing but without the worry of buying an expensive radio set and biffing it breaking your investment? Well this is the solution! Its very easy to make your yourself using parts around your house. Mostly everyone has things at home they can turn into something else. It just takes thinking out of the box. I came up with this Idea when my brother and I were scraping an old computer monitor for its CFL light tubes to install into another one. After having got out the light tubes, we looked through the rest of the case to see if there was anything to use. Other than some small components there was these two little speakers in their own boxes. How cool is that! So I pulled them out and figured I could use them somewhere I don't have music... thus I eventually came to the idea to put them on the bike and I suddenly had a awesome product for FREE!

Step 1: Take a gander around your place

To recycle/upcycle/rebuild something into something else, you gotta figure out what you want to build. For instance if you got old sock while a hole in it laying around, don't throw it away! Reuse it! But where? Well you can cut it at the hole and now you can use it as this:
-Sunglasses protective holder
-Slide it over a rusty pole
-Slide it over your bike handle bars if they are real hot from the sun or hot gear shift in the car
-Or install it on your orbital sander to be a dust catcher (this one is in my other instructable)
-Ect...

You see its not that hard, just gotta think outside the box of its intended use. Now for the speakers I used, I pulled out of an old computer monitor. Other places you might find speakers: Kids toys, old small radios, Greeting cards, Cell phones, Land line phones, Tv's, broken laptops or portable dvd players, really anything that has small speakers or makes music or sound. They all work with the same theory, which has two wires connected to them. The white monitor in the picture is the same monitor I got the speakers out of, this one is a spare but the exact same one.

You could probably use old computer speakers instead of those smaller speakers and hook them up to a dynamo which will give enough power. Might do it when i find the time :D

good instructable, favorited it!

Thanks! Yeah I should post a video of it soon, it does have decent sound if there isn't no cars driving by.
This is pretty darn cool! What if I used an old boombox? I have one that runs on batteries or from the wall. I'm a complete noob when it comes to electrical things. But this is amazing! Beats paying money for crappy China bike speakers when you can Reduce, Reuse, and Recycle!
Great instructable by the way!

Thanks! Yea man you can use anything you want. Boombox is big but atleast you would be hearing some good sound! If you got unused things like speakers laying around or audio components, it takes some simple modifying to have something unique to you. Feel free to ask anything if you need help.

No amplifier? My phone hasnw't got enough power to give those speakers power....
Sparker94 (author)  ashwinlit2 years ago
True with my android phone they hardly sound. But with my ipod for some reason they work great, they go just loud enough for the rider of the bike however.
Yeah same thing, with my mp3-player it works but my android phone won't give enough power at all for some reason. The problem is that I don't use my mp3 player anymore, I only use my smartphone. So if I could build an amp, where do I have to put it in the circuit? I'm so sorry voor my terrible English.
Sparker94 (author)  ashwinlit2 years ago
Yea thats thing I ran into as well, using an old mp3 is like using a walkman now lol. If you built a amp for the speakers, the amp output would connect to the speakers and the mp3 or smartphone would connect directly to the input on the amp. So basically the amp is in between the two on the circuit. Hope the pics help, you might have to blow them up to see them better.

Thank you!
Now I'm gonna browse over the internet on how to build a simple amp.
Have a nice day!
Oh and I think I forgot something....
Great 'instructable'!

Thanks! Let me know how it goes. I'm interested to see how yours turns out!
