I would be interested in this for the tiny soldering practise.

My problem is that I impatiently omitted flux, which I don't currently have. The board and chip are crusted with solder in several wrong places. I would like to offer the chip and Schmartboard to anyone who thinks they can resurrect and use it. Cost is nothing -- not even postage. I have some international first class stamps lying around that won't otherwise get used. So, if you're gung-ho about soldering tiny things like this, please take these off my hands and out of my mind. I'll order some flux and more supplies and do this right with fresh materials. > > [1] https://www.youtube.com/watch?v=4G1IfYguQLQ > > [2] The TLV320AIC3106 is an audio codec chip often found in USB sound interfaces.
