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)

LMAO you got me there! but thanks!

Thats nice work!

[Gizmo613]

that's what i have for a parts list
let me know if this is correct.

R1 and R7=10k ohm 1/4 watt resistor size 0805
R2,R3,R4,R5,R6=100ohm 1/4 watt resistors size 0805
R8 and R9=led's size 0603 any color
R10 and R11=100ohm 1/4 watt resistors size 0805
C3=0.1UF size 0805
C4=0.47UF size 0805
C1 and C2=22PF size 0805
crystal is a 12mhz crystal
5 pin usb connector
18f2455
and a way to program that 18f2455 (pickit etc)

If you need help let me know. I have made a handful of these myself lol.

thanks anon pretty much a smaller footprint added connector to be able to flash hex files while the soic is soldered on and added leds also
ready to be uploaded to oshpark to get them made
will uploaded a parts list in a bit

[Gizmo613]

i've updated my parts list to match Anonamous. it should all be correct now.
Also had some paypal balance so i ordered one set of 3 for only .15¢ lol.

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

the picture in the original post is outdated i redid it a few times with the help of RDC

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.

[Gizmo613]

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.
