too hung over? lol just kidding. i'm gonna continue with the current one and will post how it goes. i also corrected the parts list for myself so i dont screw anything up.

reason i suggested the 0603 was because i was gonna solder using a hot air station, not everyone has them. Damn, i was just too selfish. lol
Personally if one cant solder 0603, they shouldn't be soldering something of this caliber. just my personal opinion.

as far as running a ribbon cable, i dont like that idea much even though its a good option. i will be installing these in my customer rgh consoles and i know people like to fiddle around in there. hence the reason i am leaving these installed as almost all my customer are asking me how to flash their own nands. gonna cut a small opening in one of the side cages and grill, hot glue the the board and viola easy access. something of that nature.

also with the programming of the pic, which pins needs to be used for the pickit2? i can deal with soldering wires to the chip itself. not a big deal since most people will only be making 3 boards from oshpark.

Pins on the PIC for programming are.... in the DataSheet for the PIC, one probably shouldn't be programming them if they can't look them up. ;)

VPP - Pin 1 (Remove R1 for programming, or program the PIC before it's installed)
VDD - Pin 20
VSS - Pin 8 or 19
DAT - Pin 28
CLK - Pin 27 (Remove R2 for programming IF it's already installed in a 360, otherwise it's fine)

Screwing up is one of the best learning tools, so long as the only thing you're not learning is how to screw up.

I don't know if you have it in the gerber files but from looking at the picture in the first post you are missing a connection. Pi 23 on the PIC is supposed to be connected directly to J1D2.4

i was reviewing both the first board and the final rev. i also spotted that. it's all good though, a few of my friends wants to learn how to solder small components so i will be using these for their learning purposes. im looking into going to school as well so the first boards are gonna be my practice board for school.

here is my install





As you can see it was a bit difficult for me to solder the crystal. Ordered some real smd cystal so its gonna be another week of waiting, which is fine cause that's when the final rev will be in as well as the stencils i ordered for it.
