My SD socket doesn't yet have the four mounting pads/shell automatically connected to ground yet. I'm still learning about how to do that. I'll repost when it's done. If you use it before I repost, fix that.
Which SD socket did you buy, I've got to use one in an upcoming project and am baffled by the sheer amount of different SD sockets there are.
I plan on using a MAX3392E level converter for the 5V to 3.3V level translation.
That seems like a big job, but I know why you might do this; too many good things on the net disappear, and I like to have the info local. Perhaps if you do get a PDF together you will put it up here.
Thanks AtomSoft, that Eagle Editor Tutorial looks pretty good. Wish I'd had that way back when. I'm still going to enjoy reading through as there may be something left to learn.
I think it is still a Work In Progress. I can see 7 via's right off the bat that could be eliminated (From the center header on the lower edge of the PCB). Autorouter madness!
Nice eagle links. Thanks!

on the topic of eagle... When making a schematic how the hell do you make it like wireless on the schem?
Ok i know that was confusing. ill try to explain. Look at almost any schematic they have a tag on the pins like VDD might have a line to a <5v> type tag and then that tag it also on anything that needs the <5v> so anything that has a 5v tag is connected. You understand?

That was just a quick autorouter-only test. The board is far from finished. As I do it I'm relearning all the stuff I used to know how to do in Eagle years ago but forgot. Still a ways to go...
I still say, "Nice MCUs!". You can run em off fruit! I don't care much for their IDE, but I can live with it. MPLAB sets a pretty high bar for MCU IDE's.
awesome links thanks and cool fruit stuff. I doubt if we had to run it off fruit it would be very usefull maybe a watch? but then you lose time in between fruit but thats cool!
God, I'm getting old! I didn't get what you were saying.
Difference between a MOSFET and bipolar transistor? In a 'nutshell,' the transistor is controlled by current - more current on the base turns it on harder, up to the point it saturates. The FET is controlled by voltage. There are two basic kinds - depletion mode and enhancement mode. With the depletion mode a voltage on the gate which is more negative with respect to source, chokes off the device so it doesn't conduct from drain to source. Enhancement mode FETs need a voltage on the gate to turn them on. IIRC

Thanks Beebop... Im looking at the PICDEM FS USB User Guide at the schematic. Im wondering what they use that mosfet for. Looks like it blocks the VBUS (+) from the rest of the circuit if the user supplies power via adapter. Would that be correct?
