About three months ago I came to two separate conclusions: 1) I had too many components, some of which were bought for a project that got abandoned, and had no other real use. 2) They weren't organised in anything resembling order. Not even organised chaos. So I started writing a PHP-based database to track: A) What I had B) Where it was C) What it did That is to say, a stock database. It tracks what components I have, where I've put them (i.e. what the label on the storage box is) and how many I have left. I've also got - on the drawing board - "component trading" functionality. More like: Fred has a box of 20x XYZ123s. He wants to keep 5, but offers the rest for trade. Jim is looking for six XYZ123s. He searches the database, and finds that Fred has 15 on offer. He clicks on the Request Trade button. Fred gets an email from the site that says Jim is requesting a trade. Fred can now contact Jim via the site, and everything that's been said is tracked and listed. After a bit of to-and-fro negotiation, Jim offers some KAA9320s in trade. Fred and Jim send their parts to each other Fred and Jim receive their parts, then each leaves feedback for the other. The trade is marked as completed. They all live happily ever after The software is called ISIS, and there's a quick half-done demo of it on http://isistest.philpem.me.uk/. My offline beta has Digikey auto-importing ("I have 24x 199-9929-NDs, get the data from DK and import it") and Mass Import, but that's about all that's different. No user authentication yet, either.
