RJT> Been actually spending some time getting it organized, too... :-) GM> That's usually the hardest part... for me anyway. Yes, it's proving to be the case here. Concurrent with hardware issues, too. Until yesterday I never saw a HD where just putting the power connector in would prevent a system from powering up at all, so I guess there's a problem in there, and I have a thought or two on that subject, like maybe a shorted cap or similar? We'll see, if I can find the time to mess with it. RJT> _And_ doing some of the same with parts here. It'd be nice if I could RJT> actually put some of this stuff to use, instead of just collecting RJT> it! GM> I wish I could use more of the stuff I've collected. Most of it GM> jes' sets 'n' rots... Yeah. At least I've collected a ton of schematics of assorted simple little circuits, and may have the inclination to play with some of them. I like the simple approach, when it can be made to work. Some stuff gets just too elaborate, though. There was one design I can remember where a signal went in the order FET -> optoisolator -> transistor -> SCR -> bridge (!) -> triac, which I thought was a bit much... GM> The amount of stuff I've gathered together for some project that GM> I've put off until I get a round tuit, is just incredible! I'm beginning to hate that. GM> And stuff that has broken and is waiting to be fixed... I've surely had enough of that, stuff that isn't fixed is either going to get scrapped (like I need more parts!) or just tossed. A couple of VCRs came my way recently, the one got brought up here, boards yanked, what usable bits off the hardware pulled out, and the rest was out in the trash in something under a half hour. The other one is sitting out in the back of my truck, waiting for me to do a similar thing to it. I just don't have a box handy to toss the boards into, to scrap 'em. Even at that, I don't need the parts all that much... GM> Here's an oddity that you'd appreciate....
