hey, guys.
i really dont have that many details, but i´ll try to elavorate.
i´m trying to replicate a piece of hardware thats missing from an electric drum module. I have the schematics for the circuit, but no values for the parts.
basically it has a 3v input, and if you press con the diferent switches, it divides the voltage to 3/4, 2/3, 1/2 or 0. dis changes are interpreted by the drum module thus produsing diferent sounds when you stricke a pad (like a drum hihat pedal)
so, i´m after the values of R1 to R6 in order to be able to build the circuit. i have limited electronics knowlege. so the formula it´s beynd my reach.
so now, anwering the questions
Are you trying to generate five voltages 0, 1.5, 2.0, 2.25, and 3v or something else on the output?
i´m trying to generate five voltages 0, 1.5, 2.0, 2.25, and 3v
Also, what is the diode needed for, and is it to be considered an ideal diode or real life diode?
it´s in the original schematic. I guess it has to do with the switches not been connected to the common ground.
Also, what is the input voltage?
3V
Also, is there any load resistance to consider?
no sure.
I measured the drum module output (its a trs conector that connects to the circuit trough a stereo cable) and I get.
R/T=60kΩ / -1.3volts
S/T=-90kΩ / 3.3volts
S/R=73kΩ / 0.05volts.
i hope this clear it up.
thx again.
greeings, Nacho.
