I hand drew the double sided circuit for the SIM reader, and after washing it and soldering most of the components I realized that the entire circuit is mirrored. All the components are backwards and upside down, and for the buffer chip, pin 1 is at pin 14 (or whatever the correct number is).
It took me around two hours to hand draw the board and check for defects, so is there any way I can shift some things around to make it still work?
Thanks,

Re: SIM card reader PCB - backwards
you could print it backwards? i dunno. thats a common thing for beginners. you only make that mistake once
