I've occasionally brought a set of computer speakers into the bathroom with me and plugged my mp3 player into them. While this is nice, it's a pain in the behind and I'm always nervous about splashing them and shorting something out.
I decided what was needed was a waterproof enclosure for the speakers and the mp3 player. I actually built this project as a Christmas gift for my girlfriend, as she loves singing in the shower even more than I do and is actually good at it. I did my best to make this look nice and professional, rather than my usual cobbled together mess of wires and circuit boards.
Just a quick warning, I don't know how waterproof this really is. I suspect it'll be safe to splash it every now and then, but I wouldn't recommend actually using it IN the shower. Nearby should be good enough.
Here's a little youtube video I cooked up for this instructable. Some of the shots are pretty dark, but I think I've figured out how to avoid that in the future. On the plus side, It does have me singing in the shower!
***UPDATE 5/5/10: If you build your own set of waterproof speaks, post some pictures in the comments and I'll send you a patch!***
Step 1: Gather Materials
- 1 pair of 9 volt computer speakers (from your local thrift store)
- 1 waterproof container that opens easily (I used a pantry storage bin from Fred Meyers)
- 1 power button of some sort (mine was harvested from an old printer)
- 1 pair of disposable rubber gloves ***dustinbikes suggests using nitrile gloves, as they don't deteriorate from chemicals as badly, and are more resistant to ripping. I suspect this would be a good way to go!
- A small amount of light fabric
- 1 9 volt battery clip
- Silicone sealant
- Hot Glue
- Wire or plastic mesh
- Some plastic to use as a frame
- About 3" of 5/16 or 1/4" dowel
- Electrical tape
- Spray paint
- Glass/tile boring bits
- Soldering Iron
- Hot glue gun
- Dremil tool
- Hand saw
- Permanent marker
- Hobby knife
- Scissors (very sharp!)
Step 2: Prep the Speakers
After that, replace the wall wart power adapter with a nine volt battery clip. Remember to check the polarity.
With the speakers I had, at this point I also moved an oversized capacitor from the top of the board to the bottom, and replaced the dim green LED with a nice bright blue one, which I arranged to point up where the power button would be. I used a semitransparent rubber button, so when it's on the button glows blue. It looks quite nice!
Step 3: Cut Out the Speaker Holes
Next, use a hobby knife to score a line where you will be cutting--I find this helps to guide the dremel. Using whatever bit you like, cut out the holes with your dremel. I used one of the green rock looking bits. I'm sure it's not designed for doing this to plastics, but hey, it worked!
Clean up the holes so you don't have a bunch of frayed plastic hanging out, and you're done with this step.
Step 4: Seal the Holes and Install the Speakers
The last picture below is me testing to make sure it was actually sealed.
Step 5: Drill the Control Holes
Step 6: Seal the Control Knob Holes
I cut the tips off of two fingers of the rubber gloves and sealed them over holes from the inside. Once the circuit board is installed, the plastic knobs will fit over the potentiometer knobs with the rubber still in between them. I left enough rubber so that it would be loose and still turn. See the pictures below if that was confusing!
If anyone out there has a better idea of how to accomplish this, let me know. This was the best I could come up with, with just a couple of days left before Christmas.
Step 7: Install the Circuit Board
With my trusty E-6000 epoxy in hand, I glued one side of the board to the wall of the container, and also cut out a couple of dowel struts to support the other side of the board (see pics below). Your own project may not be quite the same, but I recommend securing the circuit board firmly in place.
The power switch on the circuit board is the push in click in, push in click out type. The semitransparent rubber button I harvested from an old printer was hollow, and it fit a mini sized glue stick perfectly. I cut the gluestick to just the right length to operate the board switch and epoxied the button onto the outside, further sealing it with some silicone.
At this point I also taped off the outside of the power button in preparation for the next step.
Step 8: Paint!
Step 9: Make a Speaker Grill
Step 10: Control Labels
Step 11: Finishing Touches
The final thing to do is to cram a little light fabric up into the speaker case. That will keep all cords out of the way.
You're done! Now go and give the gift of music . . . in the shower!
