Just smack my PIC!!

Testing/Troubleshooting

Ohhh Nooo!!! >:(

Stupid me!!

Just Insert the power cable on the core to the 5V output and BANG!!!

Damn it!

Seems like the pic isnt there any more R.I.P

Tried to program it but that doesnt work.

I Changed the 7805 and then I got 5V again .And the SID 6581 seems to work (put that one into another CORE-SID).

Now to my problem! >:(

I got 5V on the core and the sid.OK.

But when I put the SID into the socket the 5V drops to ca 2V does any one know what else I got to change, the electro caps for an example and I wonder if I smack the 74HC595 too…

Stupid me Christoffer

Changed the cap 2200uf/16V and the 74HC595 and Burned the new PIC16F877A

and its works…

Learning from misstake!! :-/

Hi Christoffer,

Bullshit!  :(

You are the second user who killed his PIC on this way; it wasn’t a good idea to add this junction near by the power supply input :-/

I will add a note to the core page that the J2 pinheader should not be mounted if it isn’t used.

Best Regards, Thorsten.

P.S.: great that the SID still is ok!

Just an tip from me… :wink:

Never be tired,drunk or eager when connecting power to the core!!  ;D

Its expensive… :wink:
