My current thoughts on the portable amplifier is to incorporate inverter technology to enable the use of 2 AA batteries instead of 2 9volts. The change should allow for better battery life and cheaper operation. This will also open up the possibility of using USB as a power source to make a cheap but High fidelity sound card.
Two chips that I have looked into so far include the LT1073 and the common mc64063.

Update SHO pedal
Unfortunately I have yet to get the super hard on to function correctly. Perhaps a different MOSFET is in order.
