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.
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.

[dragons_fire]

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???

[mackrackit]

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....

If I had a dollar for every one of those magazine articles I've seen that was obviously wrong (well, I'd have about 10 bucks, but the point remains the same).

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....

It's not as big of a deal as we're making it out to be....but again, it could kick you in the arse in the future...

P.S. Watched the video...pretty neat stuff...

An adapter is the only way I know to board a PLCC making one should be easy or http://www.arieselec.com/products/18014.pdf

Yes, selling it. Looks like something that would get some interest.

I think 20 mHz will work, as you say, the motor drivers free up the PIC.

So your a fellow HAM north of the line, cool.
