Step 1: Find The Perfect Tin

A perfect tin may have come with cookies or kerosene in it. You may find one on eBay or in an antique shop. I got mine in the local thrift shop.

Step 2: Select A Speaker And Create A Template

Once a speaker is selected that will fit in the tin, create a template of the speaker to transfer onto the tin. Trace around the speaker and then cut the template out. Cut the center out to Size the hole size.

Step 3: Locate The Template And Transfer The Marks

Measure and mark the tin as needed to locate the template, then tape the template in place. Use a marker to trace the cut location on the tin

Step 4: Drill And Cut An Opening

Use a drill to place a hole at each corner. Next use a large kitchen knife in one of the holes to drive down and cut the tin. Use the knife in this way twice to carve out a wedge to allow shears in to finish the job. Use tin snips or heavy scissors to finish the job. A note of caution!!! Cut tin is razor sharp, use care and protective gloves as needed to prevent a nasty cut!!

Step 5: Clean Up The Cut And Drill Speaker Mounting Screw Holes

Use a file to clean up the burrs left over from the cutting. This will remove loose material, but the edge will remain razor sharp. Line the speaker up to the hole and ensure that the cutout is good, some recutting may be needed to tweak it into shape. While the speaker is lined up, mark mounting screw holes and then drill them out!!

Step 6: Cover The Sharp Edge

Get some clear tubing such as is used on oxygen masks. Cut just enough to go around the hole. Mark a straight line on the tubing and then slit it open. Use a hot glue gun to affix the tubing over the sharp cutout. When done, the tin will be less dangerous.

Thanks! It is really fun to build and listen to your music with. My wife has even connected it to her computer to watch Netflix.
Based on the instructions, I made this one that looks like a camera. I used three Altoids tins: two big ones for the speaker system and one small one for the 9v battery. I also added volume control, power button, and an indicator LED. Your instructable is awesome.

Nice work! Love the DIY gasket made of clear tubing.

I bet it sounds a bit tinny.

Actually it sounds great. I will post a video of playing music from my iphone on here tonight.

Here is the link for the youtube video of my red tin MP3 player. Thanks again for looking. http://youtu.be/FAV1i2zAY8Q
It sounds great through my 5.1 surround system here. That still doesn't tell me what it sounds like in person though. I'd be interested in hearing the difference head to head against a decent wooden cabinet. Who knows, maybe it isn't as much as I imagine it would be?
I recommend taking full advantage of the clear tubing by adding some LEDs inside the tin facing the tubes to make it look more awesome. It still looks cool though; I especially like the speaker that you chose. :D
