heres the .PCB file (PCBexpress) of my board as it is right now.. if anyone is bored and wants to take a look and see if they can see anything wrong, let me know...
if you have any suggestions on how to make it better, those would be appreciated too..
i think im going to remake the board.. i like making them, its half the fun..
i had to ZIP it or else it wouldnt let me upload it...
thanks for all the help guys.. i like playing with this stuff until i can get it to work... but this time its getting a little frustrating because i cant really seem to find the problem..

A lot of people, myself included, would be more than happy to have a look-see.Originally Posted by dragons_fire
Could ya dump the file as a pdf or some sort of 'standard' file besides that PCBExpress file?
|
Skimask- PCB Express is free and a small download, turn layers on and off, nice program.
Dragonfire- by chance have you breadborded this this yet, at least the parts giving trouble? Looking at your layout now.

well, i was thinking about a pdf, but the reason i left it as a PCB is that it will still have the layers... but here it is as a jpg
i think i will attempt a new board, i just wanna make sure everything is good before i do it...
did you watch the video???
|
Video is good. When it is finished it would make a good kit.

Again, I have not used this chip.
The trace I mentioned before was the program trace. But I still think the MCLR part is different than the data sheet, data shows diode going VSS?
Other than that and a few sharp turns, I do not see a problem.
The sharp turn thing also give a real nice place for arcs to show up.
Whats the law? Things in motion want to keep going in the same direction? Even electrons.

im at work now, but i will have a look at the MCLR diode when i get home... like i said, im just going by what the nuts and volts says for ICSP, it may be wrong for this chip.. and thats exactly why i appreciate youre help... because i have never used this chip before either, so im learning lots as i go..
about breadboarding, is there an easy way to put a PLCC on a breadboard?? without making a board with a header than can be plugged into the breadboard???
when you said "kit" i dont know if you meant selling it, cause im just doing this fur fun, but i guess anything is possible...
i will look at the sharp corners... i know they arent good, but i didnt think it was as big of a deal as it seems....
