Converting 9.6V DC Voltage for AVR Oscilloscope

[mattb8818]

I'm currently in the process of building this project:

Here's the schematic:

I was wondering if it would be possible to power it with a 9.6 volt battery pack rather than 12 Volts. And if so, how would I do this? Thanks.

Just a quick glance at the schematic, the 12V DC supply input goes directly to 7805 5V voltage regulator. That means you get apply 9.6V DC supply to it without any problems. The only issue is that 12V is tapped by a 8.1V zener regulator for the op-amp front end. Kind of too high, so I'd replace it with like 6.2V zener and adjust the pot P1.
