Or pepakpan should think about DC-DC converters like mc34063.Prototyp_V1.0 said:
Agreed. Thats the sensible way. But it depends of how much current, and also the power supply (if it is a battery/solar cell or iv it's just a power outlet with a DC supply)haker_fox said:Or pepakpan should think about DC-DC converters like mc34063.Prototyp_V1.0 said:
If it is a DIP package, you may use AVR programmer from www.ikalogic.com/isp.php/pepakpan said:I would like to thank all for their replies. I tested with 7805 and its working.

My one more question is...
I would like to design a pcb with atmega8 controller. So to program this controller I need to have some interface between controller and computer. One more thing is i will program this pcb only once. So there any way of programming it without having USB or RS232 connectors on pcb.
any way , you managed you need . Finepepakpan said:the power supply 24V is not my wish... its a standard power supply used in a system where i have to use this pcb....so its the only option...
