I've started a bare-bones spreadsheet on a Google doc listing much of the component inventory I have. It's incomplete; the stuff I've had for a long time, or salvaged from scrap, or bought for my own purposes is not on there. The quantities are approximate but by and large fairly accurate.
Mostly, it's stuff I scooped out of the waste bin at work and brought home: ICs, resistors, capacitors, etc. Some of the stuff is fairly worthless to all but the most hardcore hobbyist- 0402 resistors, for instance, or QFP PCI bus arbiters. There are more than a few useful items, however.
My offer is this: if you need parts off this list, let me know, and we'll work something out. I'm not looking to make a ton of cash off this, but it has been a lot of work to collect, categorize and inventory the parts, and I'd like a little something to make it worth the time I've put into it. I'm thinking half of what DK would charge is my probable price point.
