Thanks Steve. I got the oscillator and the counter, but I don't get how you trim it down so the counter shows exactly the mS. How do you get the voltage... Wait, I get it! Sort of I think! Electronics is a bit like programming, but IRL, voltage and cycles being important variables
Most of the oscillators I see when scimming through my kind-of-local electronic parts shop has a lot of legs, most of them have four, some are like ICs. Some have variable frequencies... Which one to choose? Is there some kind of standardisation, like there is with resistors? There is some different kinds of counters available here, mostly 'impulse counters', that would be the correct type, right?
But again, this would in theory have the same accuracy as the version using the soundcard? Since I can sample in 99.6kHz? Or do I loose something on the way? Which is the most accurate? The sensors are essentially the same, right?
On the microcontroller thing in the blog link, i think that is above me.
