does anyone have any echoes reliable on that kind of thing.
if so, does anyone have one? that we can connect an oscilloscope to the signal output to know the frequency and intensity and publish a substitution diagram, pcq 300 to 400 euros for a 555, a power transistor and a cell in US, it's really exaggerated: there are 25 euros for spare parts, Conrad price (ie 4 X more than industrial cost prices).
some even claim that this could increase the efficiency of oil heaters.
you all know me, I ask for proof, no more.
