Re: eBay Chinese Electronic Clock Kit
While visiting my Psychic advisor, I asked and she said the 7805 is cooked.
Before you go to run the clock from an AC adapter, pull the MCU out of it's socket and measure the 7805 puts out 5V.
If you use a 9VDC adapter and the 7805 is shorted, it would output 9V to the MCU instead of 5V and kill it. Or just power the clock from a 5V adapter.
