Re: [avr-chat] cheap DIY programming cables: anything on USB ?

I forgot to mention the USBasp variant I use.  One of our senior electrical 
engineers made a few changes, such as dropping the zener diodes and adding a 
buffer.  I have tested this programmer to work with devices powered as low as 
1.8 volts.  Of course you can pick and choose bits from the two schematics if 
you like.
