As of August 2018 the State of California has changed the requirements of the Prop 65 law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example:
ABS plastic contains styrene
PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
electrolytic capacitors can contain Ethylene glycol
Brass can contain Lead
flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
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.

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.
