So I’m build a war scythe and I didn’t realize the 1uF caps were supposed to be polarized electrolytic. I have a bunch of 1uF wima film caps; am I able to substitute these, or will it mess with the circuit? Thanks!
You can always replace a polarized cap with a bipolar, but you can't always replace a bipolar cap with a polarized.
Wima makes some great little 1uF poly film caps with a similar form factor and lead spacing to a full-sized electrolytic. I'll generally replace any 1uF electrolytics in the signal path with one of those...unless it's something with an ungodly number of the things, like the EQD bit commander.
