How about make sure that all your threads are linked together so it will be easy to move around them. I think it would be best to add them to the first posts as an edit. If you have the energy, how about putting together a spreadsheet on what you end up with. --- End quote --- Good idea -- added links. |

I spent several *days* ordering infill for my passives. And a week binning them. In total I spent several hundred dollars. I've still got a large box of caps and semis to bin. Newark has really good prices if you hunt around, but it's so much work I haven't been able to muster the energy to do it again. The pricing makes no sense at all. Less than a penny to over a nickel for 5% 1/4 watt resistors in quantity 100. And all I've done so far is thru hole. I dread doing SMDs. But at least they are cheaper. Caps will really make you crazy because there are so many varieties and voltage ratings. |

I wouldn't get to carried away stocking up on components.There are millions of micro chips that serve specific purposes and millions of passive components ,as you probably well know.Start with the basics.Go for well documented chips with lots of circuits to try. The LM741 op amp ,NE555 timer ,μA723 regulator.Get say 5 or 6 of each in case you burn one or two up experimenting.These will keep you plenty busy for a while,Then pick up others as you need them.Trust me ,you'll soon have a fairly extensive stock in no time.And theirs nothing wrong with salvaging parts either.It's all good.Sometimes I like to spend an evening watching TV ,pulling parts and searching data sheets to learn what they all do.It's relaxing after a rough day at work. I know it's not my place to tell you what you should do with your money.But why blow a stack of money on components you might use when you can get cool toys that you will use and need. You'll be surprised how quickly you collection will grow in a very short time. |

Yeah I hear you -- I'm just trying to (perhaps pre-emptively) stock up on some common parts so that I won't have to wait weeks by the time I encounter a project where I need to have a few things at hand. The components are cheap enough IMO. Any thoughts on SMD protoboards to practice SMD soldering? |
