I want to build a simple flasher for use with 120v ac. It won't need to run more then about 60w. I found this
https://www.redcircuits.com//Page20.htm
but it says it for use with 230v. I'm not sure if this is 240v ac with 2 hots like here in the states, or if its 230v with a single hot from another country? Can anyone tell me from looking at the Circuit diagram if it would function with 120v without modification?
Second, why does it use 1000v diodes in the diode bridge? seems like way overkill? Would some 800v ones do?
Third, I'm trying to build this with on hand part, but don't have any SCRs that i'm aware of. Does anyone know if they can be found in any common household electronic junk? I have alot of old stereo equipt for parts, but I don't think SCRs generaly live there. Anyone have any ideas so I don't have to order one? lol
