theres the image of the board, and i will attach the eagle file here too.
i labelled all the "important" pins. the rest go to I/Os.... and MCLR2 resistor, is a 1Mohm resistor, and its for PGM. i just didnt relabel it when i put it in there... and there was an issue with the gnd side of the caps, so i ran a jumper wire from there to the ground pin..

Probably another wrong one, but I can't tell from the picture.
Looking at some of the holes, they don't seem to be plated thru.
It could be reflections from the other side or something.

Where it would matter the most (if true) is on the +5V pin on that connector I should have been looking at the first time.
It doesn't have a good solder joint on the top layer, which is the side the trace connects to.

If the thru-hole plating is intact, it probably won't matter.

If I remember right, from the other Treadbot thread, these are homemade PCB's correct? Probably not plated thru holes unless he's got some fancy-shmancy equipment.Originally Posted by Darrel Taylor

But that's easy enough to work around.
I'm rooting for that to be the fix..........Big bucks....no whammy's......STOP!

the treadbot board was homemade... this ones not... i can get these made at Alberta Printed Circuits for less than it costs me to make them.. and these ones have thru-plating and better traces..
|
I lost again...
I forget...aren't you 'just up the street' from me? Calgary or something?

Me too.

yeah... . i just dont know about this board...
im in Calgary, and its -42C with the windchill and im workin outside...
Alberta Printed Circuits has a prototyping service that is two boards, double sided with thru-plating... these two boards (the top and bottom were joined together and then i cut it after) were about 3.2" X 2.5", and cost around $36 total... so each board was $13 and there made next day.... its almost not worth it for me to make them....
so i have another board the same as this one, so i might pick up another PIC and try it all again just in case i shorted something or the PIC is bad...
I have no affiliation with apcircuits, but they do good work and they have helped me through design problems so if youre looking for somewhere to make some boards, take a look at them...
eagle cad takes the schematic (which is easy to make and troubleshoot) and makes it into a board, then i email that to apc and then solder it together... there isnt a lot i can do wrong if the design is right, and the soldering is right...
