Y.A.I.A. - Yet Another Ipod Amp





Introduction: Y.A.I.A. - Yet Another Ipod Amp

About: I like to tinker with just about anything, sometimes it works out in the end. Have fun looking at the projects, try tearing something open and let me know how it goes. cheers, -Joe

This is another iPod amp, but it uses an old computer speaker and a CDR Case.

Step 1: Parts


CDR case.
Vellema n 3w Amp : K8066
RadioShack 1/8" Panel Mount Jack: 274-249
RadioShack 4AA Holder: 270-383
RadioShack 9v Snap Connector: 270-324
RadioShack Minii Toggle: 275-624
RadioShack 12" Shielded stereo cable: 42-2497
470ohm resistor
4 Nuts/Bolts
Speaker from a set of computer speakers

Step 2: Build the Amp

Build the amp following the instructions that come with it. Its also a nice PDF is available from the velleman site.

Step 3: Cut the Bottom

Cut the post off the base of the CDR case.
Drill holes to mount the board
Drill two holes for the AA holder so you can secure it with a zip tie.

Step 4: Cut the Top

Cut the top of the case to fir the speaker and make four holes for the nuts to hold the speaker in place.

Step 5: Switches Etc...

drill three holes for your stereo jack, switch and LED.

So you might want to solder your power switches, led and stereo jack up now.

The case opens up so leave plenty of room to open and close it.

I used the resitor just soldered to the leg of the LED as shown here.

Step 6: Last Part

Now solder the switches/ jack /speaker to the board and make sure it works.

    Just simply not powerful enough unless you are prepared to spend big $

    I'd put 2x sanyo enloop rechargeables in there as they last extra extra long. or even 2x lithium primary cell AA batteries that last extremely long. Imo, I'd go with the extra long lasting rechargeables are they can be re-used about 1000 times.

    Hey i built one of these, it works great, awesome instructable.

    My stereo is better, although a few hundred pounds heavier, but it moves around easy enough. If I need to "make noise" for other people, such as at a party, best bet that it can't be that good if all you have is one of these. Although it's not bad I will say, just doesn't make sense why people wanna use this. Does anyone wanna hear other people's music as they're walking down the sidewalk?

    I'd say its more for if you are in your room and dont want to put your computer on, but dont want to be tethered to a pair of headphones

    Well I don't listen to headphones through my stereo, jeeze, and why anyone would be bothered to turn their computer on is beyond me, takes a few seconds of your time, I guess people can't wait that long

    Did you miss the red "be nice" note on the comment box? I think its an interesting way of housing an amp... throw some LEDs in there and you're all set.

    I noticed your berdacious humour is irritating to what I'm trying to point out. It may look nice, but for your average person that has actually owned a few stereo's in their life probably wouldn't build one of these.

    So lets some people don't own a stereo. Ha. What now? I guess this project would work for them. I probably won't make ginger apple cider, but that doesn't mean I'm going to make irritating negative comments about it. Woot!

    Haha, I now am a prime of example of how this tutorial is useful - im currently in Canada, living on the IDEA of a dime (haha) and my laptop died before I left home (New Zealand) so I left it there... so I have an ipod as my only option of music...

    "Well I don't listen to headphones through my stereo"... "Yet another IPOD amp" lol

    now tell me, is a few hundred pounds very portable???

    Certainly more portable than some of these PA systems that DJ's carry with them.

    are we talking about those "PA systems that DJ's carry with them"? now how, in any way, does that make sense anyway? no matter what you compare a few hundred pound stereo to, it STILL WONT BE IN ANY WAY PORTABLE. of course, it will be louder, but is that what we're looking for right now? this instructable focuses on portability, not loudness

    okay you have me at that. However, I've been thinking for a while of putting my truck stereo back in my backpack for a while (the truck isn't road worthy right at this moment). I did this last year with a lawnmower battery and 4 120 watt pioneer surround speakers, it was PLENTY loud and all it took was a $80 car stereo and a lawnmower battery. I was thinking of perhaps something maybe lighter and I'm not sure what else I could use for a battery that will last as long (it went all day without dying). Also I'm thinking maybe of using my 150 watt amp, it's for a car, but just 2 rca input and 2 speaker jacks. Perhaps I should use this instead of the head unit because it doesn't have input rca jacks :(

    but still, this is something meant to be portable and maybe even without a battery

    No, you'd use these if you were traveling with say four friends.

    or on a long bus trip for a school sport
