my project is stated as abv. i'll use the drdaq to detect sound of coin dropping n use picoscope to display the signal n at last use vb to analyze it. the last result is the vb will differentiate each type of coin.
i'll use brick as a base for the coin to drop. but i have to do a casing to isolate the noise tht will afffect the result i get? what kind of material is suitable as casing ?
if i set the picoscope trigger to none, the signal will be continuous and i can't save the coin dropping sound then. So i set the trigger to single. but smtimes when i just press the button go in the picoscope, the noise will be detected b4 i drop the coin, so the vb will just analyse the noise and error will occur.is it the picoscope is really sensitive and nt stable? or i really need a casing for the drdaq to isolate noise, and i can detect the coin dropping only?
thx a lot for ur help.
