Its using a theme I came up with for the Y.A.I.A.
Step 1: Parts
-MakeMP3 Player kit.
-Velleman Amp K8066
-RadioShack 1/8" Panel Mount Jack: 274-249
-RadioShack 4AA Holder: 270-383
-RadioShack 9v Snap Connector: 270-324
-RadioShack Mini Toggle: 275-624
-Film canister or other tube like thingamajig
-Speaker out of a computer speakers, preferably broken speakers no need to ruin a good set.
-5 momentary push button switches (N.O.)
Step 2: Speakers
I attached my speakers with nuts and bolts.
Step 3: Cut the Base
I used a 1-1/8" -> 1" threadless stem adapter as the pedestal, but you could us a film canister or any tube really.
Step 4: Drill
2 for the volume buttons
2 for the track selectors
1 for play/pause
1 power switch.
I would put them all on the upper half of the CDR case.
Step 5: Solder
Follow the instructions that come with it, its easy and the PDF is very helpful. I would plug it in to a solderless breadboard and make sure it works before going further.
Step 6: Solder
Hmmm I didn't take a pic of that 3w kit, here is the 7w kit.
Step 7: Drill Holes for the Amp And....
Step 8: Drill Holes for the MakeMP3...
Step 9: Solder the Power Switch.
Step 10: Solder the Pushbutton Switches
Step 11: Hook the Mp3 Kit Up
Look at the MP3 player kit for the pin outs.
