How will I go about making a momentary switch with a relay?
You may be asking, why don't I just get a power inverter? cause that will be to easy, i'm wanting to do this as a challenge.
The psu i've found...
The psu meant for the purpose...
So, as you can see with the car psu, I get less wattage for more price where I can make a 2 or 3 relay module for just a few dollars. The reason for these relays is because, in a pc psu, there is a constant 5 volt rail that keeps the RAM stable until next turn on, well that will drain the battery of the car, so I need the relay to completely cut power from the psu when the car is turned off, but if i forget to turn off the pc first, it will be a sudden off which is not good for a pc and i don't want to worry about that, so i'm wanting to make a momentary switch with a relay to pulse the off signal to to the board so it turns off before the psu is cut off and to pulse on when the car is on.
