Introduction: 6$ DIY Low Profile Bike Speaker
Today I will be showing an easy weekend project that might be useful to some fellow cyclist out there.
As a solo rider I get bored sometimes during my daily biking and as we all know biking with earphones is a bad Idea so I decided to recycle my old portable speakers and make it my very own speakers for riding small as it looks but it sounds good. With less than 12$ you can make your very own Bike speakers loud enough for you to hear during your biking session every weekend.
With this Idea help me win a 3d printer and I will make another version of this that will suit most bike frames out there "3D printed casing Water proof, Bluetooth compatible" also comment below to help me improve my design thank you. :D
Small but loud
This will depend on the portable speaker you have. But usually its loud anyways
LOW PROFILE....Maybe..... up to you
With just one speaker we might say its low profile but it still depends on how you will make yours too
Well you can make it water proof simply add plastic dip on the Circuit your done just dont coat the terminals duuuhhh
but for me I did not water proof mine yet since I plan on 3d printing a proper casing for this
No Problem this thing can last for almost the whole day
No for the time being since a portable speaker with too many features can be a bit bulky so lets save it for future designs.
Will it scratch my bike's frame
You might end up scratching it so I recommend making your measurements precise as possible.And apply some masking tape on the part of your bike to avoid scratches
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Parts & Materials
A bike $$$$ ?
A portable speaker w/ aluminum enclosure to be exact got this as a gift so lets say 5$
A mini switch .50$
Tools and other materials
Scarp soft plastic or acrylic glass
Aviation snips (optional) cutting soft plastic
Using your cutter and slide through edges edges and make a gap big enough for your finger nails to do the work
remove everything inside the casing including the small speakers.
I have no paint but feel free to paint the whole aluminum
Step 3: Masking Things Up
Add masking tape on the enclosure and that is where we will put our measurements and guidelines
Proceed to your bike and measure its aluminum tube just like in the photo
Know your aluminum casing' measurement W and H
Follow the example I did on the 3rd image
After doing one side do it again at the opposite side
Remember to indicate your center line~
Cut through the guide line and your casing should have this
At the other side you must do the same but cut the remaining aluminum
Step 5: Adding Your Switch
put back your speakers and find a way to put your switch and battery. Drill a hole suitable for your switch and then solder the switch onto the battery
Now that your enclosure is done lets get back to the circuit Board
Now if by any chances you have some plastic dip around there feel free to coat the PCB just remember not to coat the terminals.
Get your scrap plastic and copy what I did on the photo
Get your epoxy and enclose the gaps you see around it
Step 7: Rewire Your Whole Speaker
Rewire the whole thing and do some testing on the bike itself
Step 8: Sticking the Controls Beside the Casing
With epoxy apply quite an amount to make sure that the controls wont break off
Let it dry and do some testing if its safe enough to use outdoors
when done attach the whole thing on the bike and strap it with some zip ties to make sure the whole thing wont fall off
Thank you for reading! and Good luck with your weekend project!
