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.
