O.K. I will only post text now, but I though people would not be interested in widget talk without proof that my designs are legit and real products by way of photos and schematics. Oh well.
Powah-1, a .5" x .5" board module that fits on a breadboard, but can be used as a motion-control limit sensor, anti-tamper switch, etc. It can switch any CMOS signal, and draws nearly unmeasurable current in the quiescent state.
Powah-2, a .5" x .8" board module that also fits on a breadboard, can be used in similar applications, but has two additional features. One, it can switch up to 18V because of the matched complementary MOSFETS intended for beefy automotive applications. A barrier diode limits gate voltages to 5.1V for safety. Two, the button turn-on and turn-off times are different, also for safety. The example in the (soon to be posted) schematic sets a 100ms button on time, and a full 3s button off time.
I have calculated potential pricing based on the 4X parts cost rule-of-thumb, but I don’t know if that is (yet) appropriate here.
