How do you choose the wattage for resistors? Is there a general principle? I tend to use 0.5W because it seems to work with everything but 0.25W are smaller so I'd prefer to use them where possible.
I have made up a schematic in Eagle and attached it. It has the following resistors-
R1 = R1 on a 555 timer
R2 = R2 on a 555 timer
FB1 = Feedback resistor on opamp
FB2 = Feedback resistor on opamp
Various potentiometers.
It has a +/-9V supply with ~ 1.5A.
Thanks.
