I can develop your DIY audio amplifier and the DAC board as well. With the DAC, the price for developing should increase.
Relevant Skills and Experience
I made a few audio amplifiers before. I have some skills concern the developing audio circuits with care about the noise and sound quality.
Proposed Milestones
$144 AUD - power output, power supply stability, amplifier class, grounding, inputs, schematics and board.
Do you want an amplifier with DAC circuits? Medium or high power output?
