Got an idea here.
Let me know if I am going about this the wrong way here.....my first attempt at this.
I want a portable iPod DAC. Seems there is only one made so far, and its around $700 bucks. That, my fine folks, is a bit too expensive for my taste.
So that got me thinking on how to do it on my own. Got in my car this morning, and plugged in my iPod to my Kenwood CD player with a USB cord. Then this big lightbulb went off. I started thinking, if $100 car stereos can act as an iPod dac, then why is the only portable offering $700? I found out why. Apple "made for ipod" testing and Apple approval, which can run over 100 grand! That's why the small companies have to charge $700 for a simple product, and a big company like Kenwood can fit the tech in a cheap $100 car stereo.
Very recently I bought a Pure i20 ipod doc. It runs off 7.5VDC, and is quite compact. It also has a DAC built into it, and it sounds quite good. So, why cant I steal the circuit out of this, and put it into a portable size case and run it off a 9 volt battery?
If these companies can offer sub $100 iPod DACs, then why cant i make one for cheaper? Tonight I took apart my Pure i20 dock, and sure enough, the circuit board sound very easily fit onto a portable DAC size case.
So, anyone have any thoughts? Look back for updates as I get this device built!
