Hehe...
Then we add some input conditioning circuitry and attentuators and
such, and
when we're done we'll have built ourselves our own digital storage
scope.
You that ambitious? I'm not, these days.
Not everyone feels that way. Or we'd still be at the "bang two rocks
together" instead of "surround sound that makes you dump in your
pants" sound system. ;')
For an audio Oscope, something from 10mV/cm to 50V/cm should cover
things nicely. 5MHz doesn't require too terribly much RF design
knowledge, especially if it's only over short distances.
Microstripline so impedances match in circuit.
People build more complex things in their workshops regularly.
For me it's not ambitiousness that lacks- it's time and money. And an
inability to focus on one task.
