Homemade testers and other soldering projects
« on: January 21, 2013, 11:07:25 pm »

What have you made? I'm interested in anything you may have soldered together yourself.
I've made my own Clear Com call light from a diagram I found online.
I'd love to be able to make a phantom power tester/noise generator.

I used to build all my own gear-mixing consoles-amplifiers-crossovers and so forth-but those can ge quite involved.

A quick dirty hand tester is a cable tester that uses series LED's with the wires.  real simple and quick and cheap.  It won't tell you if the cable is open or shorted-but will tell you if it is good or bad and is grat for findng intermittants.

A phantom power tester is real easy-just use 2 LOW CURRENT led's and series resistors from pins 2 and 3 to ground.

Now part of the problem is that phantom power is not always 48V (sometimes 24V or less)-so that needs to be taken into account for the resistor calculation.

Noise generators are easy-just Google noise generator and you will find all kinds of circuits.
