Super utility circuit to have around
I have used a couple dozen of these things since they became available. From driving a relay to control lights flashing on a 60 antenna foot to one driving an .mpg of a screech owl in my barn to keep out pests. I simply change the caps to get any range I want. Big time saver.

Works, but dont believe the documentation
I have an old pdf that has reference designators, and the current one that doesnt. Both have errors. I was modifying it for a limited freq. range, and it was way off. Found out that the 1uF cap on J3 was really 4.7uF. Other values are suspect too. If youre going to use this with any modifications, take the schematic with a grain of salt.

Fast Shipper, as advertised.
Pulse Generator 31070MI
Too bad you cant read the component values on the schematic
Pulse generator +/-
Ive used 6 or 8 of these for a 1-2 hz application. As the note indicate, you have to repeatedly cycle between the pots to get the pulsewidth and Hz you need.It takes patience at 1 hz. Also I have had 3 early failures, they lock up and then go dead.
