Looking for a low cost function generator that can do a square wave between 50 and 100Hz at 5V p to p. I know a 555 circuit can do this easily, this will be used as test equipment so they are looking for something that they can just buy and not make. I was wondering if maybe someone knew of a little box that someone sold that just put out a constant square wave. The frequency does not need to be variable nor does the voltage.

if the voltage and frequency need not be variable, then the 555 timer circuit will be the fastest and cheapest way to get what you need.

dude.

this has been totally realized, but it seems that they are reluctant to go with a in house built solution.

search for "square wave generator" on e-b-a-y.

in all honesty, you're acquaintances thought process is pretty foolish.  they are going to waste a lot of time and money procuring something they could have up and running in under 10 minutes for less than a dollar.

dude.

Figured out why it needs to be an actual function generator. It is so that they can slap a calibration sticker on it.
