If you had a USBtinyISP (or similar) then you could use that.
As you have a "Uno", you could use the "Arduino as ISP" example sketch and rig the Nano, as the target device, to the Uno. There aren't a lot of details of that specific (Nano-to-Uno) configuration, but there are examples using Uno/Duem. and "stand-alones", so you ought to be able to extrapolate based on that. http://arduino.cc/en/Tutorial/ArduinoISP
I'm working on an H-Bridge to control a drill motor that requires 18V and 50A of power. I found and example of an H-Bridge at http://www.hvlabs.com/hbridge.html . I have studied the schematic, and from my knowledge it should work, but I would like to get a 2nd opinion on it before I buy the parts.
I have a proto-shield that I use for buring sketches to 85s with. I don't run the sketch with the 85 on that proto-shield though. I transfer the '85 to a separate breadboard to test/verify the sketch/operation.
so, 1 uF capacitor for every 74HC595 and 1 pnp for every 10 leds is what i'm told...
I didn't see anything in the TI link about the "1 pnp per 10 LEDs Rule".
And he got a perfectly reasonable answer to his capacitor question (twice). Maybe going without decoupling is akin to going resistorless to some people - but you could sure fool me. Not being enough, evidently, we got the "argument from intimidation."
k, i'm taking a break from arduino and the bs sarcasm... it's really starting to piss me off and i don't need anyone's crap anymore
anyways, thanks for not making me feel welcome on this forum everyone.. wish i could say it was a blast.. but i won't lie, it wasn't thanks to all the bs sarcasm that has been dished out to me more than once.. i hope this isn't how you treat all new people to arduino and the forum.
Your frequent use of the word "piss" in your posts coupled with your reliance on tantrums in an effort to get your way sets the table.
With regard to decoupling capacitor placement - one lead should be connected to pin 16 and the other lead should go to directly to Ground (the Ground bus itself, as opposed to going to some point that's connected to another point that's jumpered to Ground.)

uses 9 '595s - none of which gets "decoupled". (There is one 1uF across +5/supply on the board.) Rarely will anything on this level flop for lack of adequate decoupling.
It looks like it may not conform to the prevailing assumption. That's an easy thing to check. The best thing to do is confirm with a DMM, get out the ohmmeter (low ohms or 'diode check') - it will show signs of conducting in one direction (but not the other).
