You may have seen the DIY altoids amp somewhere else, but this one is easier than the other plans I have seen. This project can be completed in one sitting, depending on how long that
sitting is and how precise you make everything. It will cost you about 10-15 dollars depending on what you have lying around the house. Sorry the pictures aren't up, I am having a problem uploading them.
Step 1: Time to Void a Warranty!
-small Phillips head screw driver
-electrical tape or duct tape
-hot glue gun (optional)
-wire strippers (won't be mentioned, but they will come in handy)
-drill or dremmel tool (to cut through altoids can)
-cheapest cassette walkman you can find (get one without AM/FM, that requires more space, and it won't fit in the altoids can. It should cost around 5$, mine is a Durabrand model 820M...real high quality stuff here folks)
-altoids can (empty, eat up)
-audio in jack (like what you plug your guitar into)
-x2 AA battery holder (side-by-side, not end to end )(x2 means holds two batteries, not two holders)
-extra wire (not neccessary, but will probably come in handy)
NOTE: If you don't use the same exact stuff I do, yours may not fit into the altoids can, if it won't fit, find another case, I recommend the cassette player case.
Take the tape player apart, do it carefully, you may need to know how it goes back together later. Get the chip with electronics out IN ONE PIECE. The motor and switches may be
attached, these will need to be removed in a later step, but first, you need find out how pressing the play button connects power to the amplifier. Follow the power wires from the
battery compartment, one of them should be interrupted, when you press the play button, it will become uninterrupted, this is where you will hook up the toggle switch, in the place of
the play button. Also, in my tape player, there was a switch labeled "bass boost", I had to cut a little of the case plastic to get the switch out in one piece, but I guess if you wanted, you could just remove it.
