Of Resistors and Capacitors
Am I the only one who looks at a schematic and dreads seeing capacitors? I don't know if it is really dread. Maybe it is more disappointment. It just seems like I always have to special purchase the capacitors, which puts a crimp in spur of the moment building.
When I first started building 3 or 4 years ago, the best purchase I made was not a piece of equipment but rather a $15 resistor pack from Radio Shack. It is kind of ironic. But it really was. I have not had to special purchase a resistor for a project (except for 1% or higher power ratings) since then. The pack includes at least five of every 5% value 1/4 watt resistor.
But for capacitors, I also purchased the Radio Shack disc and electrolytic packs. These have been helpful, but because they are a mix and match bunch of values the ability to find what I need is much more hit-or -miss (maybe better said miss-or-hit to represent the frequency.)
Is it not possible to get a pack of capacitors that contain every value? I think there is also the matter of different types: ceramic discs, metal film, poly, mylar, mica, and on and on.
Then there is the issue of variable components. If I need a potentiomater I can still go to Radio Shack, but a variable capacitor, HAH! Better start looking at my catalogs.
Has anybody had a similar experience? Or is there a good capacitor pack that would help me out? How about an electronics parts store within striking distance of San Francisco?
Sigh!
