Your circuit looks good to me though.
Thanks, I have learned a lot just being on here.
I hope to have this little project complete by the weedend and start another.
I am using LEDs for the flasher I'm building, they flash faster and are brighter. Now they are cheap enough too @ $16usd each.
Incandecents are really high current until warm, that is why most new stage lighting dimmer packs keep the filament warm for faster flash rate and to keep the lamps from burning out due to inrush current.
Is your project something that you can use LED lighting? Is your project something that could be done with automotive relays that are controlled by the MCU? I am a huge fan of relays in the accessories that are required on the trucks at work, switches last longer and I can shut off everything via relay when the Ign key is removed.It saves a lot of dead batteries.
Those relays are cheap and can switch quite fast, I considered using the relays, but switching is not quite fast enough for me.
30-40 Amp contacts and I have never had to change out a bad one that I have installed. Factory ones on the other hand go bad all the time, if I even suspect a stock relay it gets replaced, been burnt by them a couple times, never again.
Good luck...
