So is my dad thats why I indicated that I have the probabole parts needed. Cause, I need it for game playing not audio recording :/ I figured I may need an amplifier board.
I may look into that but, I didnt want to have too buy like a whole bunch of stuff. Guitar Hero an Rock Band just don't like not haveing a mic :/
Cool that he is also an ET, but its far cheaper and far less time involved to buy one of these than it is to create your own. Even if you are able to get the parts needed and come in at less than $8 which I estimate that parts alone unless you can buy through a source that gets volume discount will go beyond $8. Plus you will have to hand solder all the many connections and hand soldering surface mount chips takes a lot of skill and precision not to stress the component with the heat running up the components legs and end up with a solder bridge when the flux primes the legs and the molten solder quickly flows and bridges them.. ( BEEN THERE myself and having to solder wick the bridge away without damaging the chip and the PCB ).
After all of this is done. Many hours invested in making this device, you then need it to be supported by the system with a driver. I am not aware of any open source or generic drivers to pair up with USB Analog/Digital Audio communications to make it work for your project.
If my child approached me as an ET, to make this device, I'd just buy the $8 adapter and be done with it. If my child approached me wanting to make something that doesn't already or affordably exist that is a must have, I'd take the project on if its one that wont cost too much time and money.
Fortunately the only request I have had so far was my 8 yr old daughter wanting her own computer and wanted it to be Hello Kitty theme,... I said thats easy, lets go shopping! So I took a old late 1990's beige steel case computer tower I already had and spray painted it hot pink with all the boards, drives etc removed, and bought her a bunch of Hello Kitty stickers to affix to it after I stuffed an old but still powerful enough Pentium 4 HT 2.8Ghz motherboard into it with 1GB RAM and a GeForce 6200 8x AGP video card for her gaming (Angry Birds and World of Warcraft Starter Edition FREE) and web surfing ( mainly youtube music videos ) etc. Only problem now is that her friends saw it and they want one just like it... and I cant sell Hello Kitty Computer towers without fear of being sued. So I told the parents that if they want, give me a computer and I will spray paint it hot pink and they can add their own stickers etc that make it Hello Kitty Theme..LOL
