I am wondering if a hall effect sensor would be better than a reed switch. I have considered this but have not found any online schematics to be helpfull. Basically all I would need is something to run off of 12V dc, and drive an R/C circuit to convert the pulse to a triangle waveform. I am...
I am having a problem with a very simple schematic. Basically the object is a reed switch tracks rotational motion, sending 12V pulses into a simple square to triangle circuit (integrator, rc circuit)driving an led. The problem is the reed doesnt like the cap. When I bypass the cap, circuit...
Hello, I am attempting to repair an audio mixer. The manufacturer will not release the schematic and the board needing repairs is two sided, so I am somewhat reluctant to map out the schematic. The board is a 17/48 volt supply/regulator board. At some point the wires from the external...
PCB Board below broken diode says "51V" and what remains of the diode (it's glass, broken in half) is red in color...... 51V zener diode would be my guess, and it's small in size (DO-35) but not the smallest diode I've seen (tiny bit smaller than a standard 1/4 watt resistor) any help in...
