Except for that missing connection, the project is quite good. Keep in mind that the LM555 doesn't need to be fed using a regulator, although the regulator will improve the 555's precision.
I fail to see a problem with the diode bridge.1. His full-bridge rectifier isn't wired correctly - I had to look at the thing three times.
So post your schematic. Looks the same to me.No he was right the diode bridge was wrong.
It should have been like this
or like this
It was I who mentioned that earlier, but that case does not apply when you have a 12V DC power supply already. I was refering to the case where no transformer was used, or a 60VAC transformer was used instead.No, the 555 does need the regulator. If it does not use the regulator it will burn during the time when there is a low current in the coil. Or something like that, someone mentioned that earlier.
So as long as i change the fet this will work as is?
about the diode bridge the diodes do not all point in the same direction. the bottem is like a 'V' and the top is like a '^'You are correct that the diodes in a bridge all point the same direction.
Where the cathodes join is the (+), where the anodes join is the (-), and the other two points are for the AC.
