I'm currently trying to modify the input of a Velleman MK140 audio kit to accept an electret condenser style microphone (generic computer mic), because it is currently set up to handle a dynamic mic. I could get a preamp kit and feed it into the input, but I thought it might be easier/more compact if I just modded the current input circuit.

The audio quality does not have to be great, so the simplest solution is probably the best. *Yes, I realize this is head-fi, so this statement is ridiculous . If you know of a forum that might be a better place for this, feel free to post a link.*

Does anyone have any pointers?

Thanks for any help!

I've used something like this in the past
its very easy and provides power for the mic
