I spotted a similar idea via Flickr last year. Someone figured out they could use a second 168 ATmega8 to do USB-RS232 and put it on one board.

OK, so the main similarity is that it's Arduino, and there's two ATMega168s ATMega8s on the PCB, but it's still pretty cool.  ;D

I've been following this fascinating thread from the beginning and I'm really happy that it has concluded in such a great way.

Well, I managed to get the 168V to work with my NG board just fine.
That was pretty satisfying actually, since it was the first time I have attempted to burn the bootloader and the first time I have tried to use my USBtinyISP kit.
Now I know how people can get so excited over getting that LED to flash.  smiley
For the record, the fuses I used were:
Low: 0xFF High: 0xDF Extended: 0x00

I found the e-textile page very helpful for getting a better idea of setting fuses for low power

slanbuas, I encourage you to give it a try, the 168V looks pretty good for low power use. If you look at the datasheet, a 168V running at 1Mhz uses only .55 mA, compare that to the idle current of the standard Arduino at 20ma - not bad!

yes, that and you'll need to change the crystal to 8mhz... other than that it should work fine at 5V.
What will you do to program it when you run it on 1.8V? I don't think you can run the FTDI usb chip lowers than 3.3.

I thought that if I set it to 8MHz that it would use its internal oscillator. I hope that would mean that I wouldn't have to mess around with changing XTALs. I wasn't particularly looking at low power applications myself, I just want to be able to use ATmega168V-10PU chips because I can get them cheap locally.

I have an ATmega168v-10PU chip sitting here on my desk.
I'm planning to put the Arduino bootloader on it using my USBtinyISP (http://www.ladyada.net/make/usbtinyisp/index.html), but I have a couple questions of my own.
Will I be able to use it in my NG board? I think that if I change the bootloader and the makefile so that it runs at 8Mhz it should be OK.
