Hiya
I've got a scenario where I want to power-up a 12V supply for (say for ~60 seconds) based on a momentary supply of 9V current (basically I want a doorbell push to turn on a small LCD monitor)
Its been a while since I've played with breadboards, but it strikes me as something straightforward but googling for components has drawn up a blank.
Anybody got any pointers?
Cheers
Colin
