I tried to read the link in the sticky, but the page has been dead for the last 24 hours:
http://www.interfacebus.com/Design_Capacitors.html
I understand I need them. I don't fully understand quite how they do what they do, but I understand that the chips use power, which makes the power supply ripple and wibble, and the caps counteract that. I think.
I don't really understand the logic of using a 22uF electrolytic and 0.1uF mica on each chip, but I'm prepared to just "go with it".
However, is there a problem using larger value electrolytics? I ask as I've already got quite a few 16V and 25V at various values between 100uF and 1000uF, which if I could use would mean I don't have to buy any more.
Also, should I just "stock up" on 0.1uF mica caps to use all the time next to any chips? (I don't have any mica caps in my box) or again could I just go for higher value as a lazy "catch all" - ie 1uF mica?
