Very interesting. Following food for thought for your next board spin.

  1. Connecting test signals directly to ADC IC could be risky - too easy for typical hobbyist to break the chip. At least buffer the signals if you do not provide input protection on the main board. Of course this becomes moot point if your optional ‘Voltmeter Interface Board’ becomes a standard part of the end product.

  2. P.E. leakage from AC mains through typical computer power supply can be problematic for some systems. Unless the test signal source fully floated, do not be surprised to see > 5mA (ITE safety limits) leakage for some hobbyist’s setups.

  3. Linux? OSX? Probably do not need to worry about latter, as anyone that can afford apple stuff would probably buy a stand-alone scope.

Methinks the $50 price point is good, and some willl say that cost does not scale with performance - but do not let anyone influence you on this, as dollars per performance seldom scales linearly.
