EXT Power / is a kind of sketchy

Ok, I m working with a NG AtMega8. Usually I use USB Power and evry thing works fine. This is the first time to run the board via EXT Power. I switched the jumper and so on....I plug it and RX TX started to flicker instantly. I knew,that this was not normal. So, I my board broken, messed up or what.? Itd be so rad if someone could help me out.

BTW, the icon (in your profile) is too large, and it is taking long to load, because the original image is 512x768 and here is being resized to 43x65.

Did you test if your sketch runs?

not yet. check`t tomorrow.

Ok, here we go. I checked it yesterday, but it didnt work. Afterwards I noticed, that this failure(not restitor thing) messed up my bootloader.

fortunately, I had a second one in my shelf.

AnyhowI had to look for a other solution, cause dead line was calling - the key to my happiness was buying an USB Supply !!! :-/ Whatever, this might not be the best solution, but, hey, it works.

Thaanks alot and a nice day.
