Hi Im new on the list. my name is jeppe cohrt 25 years old music student from Denmark.
When studying music in Ghana West Africa. I find Out that
there is a lot of electronik stuff that they need down there. My friend is running a small company building speakers and amp's, and we are now working together to make some direckt import of transistors and ic's and much more.
Im now planing to make up a new small circuit and i need some help.
The circuit have to Delay the main voltage 220 some secounds (5) the reason for making up this circuit is that they offen have lightoff, and when the electricity is turned on again, they are told from the goverment that it's is best if they have turned the freazer(collers air condition m.m.) off. I think that it's because when all these devises are turned on at the same time they need more curent (A) than the eletricity company can provide.
People belive that. it's is can damage there things if they are not turned off, when the electricity it turned on again.
I know how to make up this small circuit with use of an small power supply to drive the relay to be turned on
like a speaker protection delay.
But the circuit need to be very small and very low cost
SO MY QUESTION IS can i make the up without use of power supply. can a power resistor run the relay and the driver transistor ???? and how
If any can tell me how or make up a circuit for this
I'll be happy to hear about it.
