Common house items

 

 

A table with circuit boards on it.

Transistor radio?

Two way radio?

big bills' sasquatch mating call and pheromone spraying device 

doorbell?

The back of them are typical printed circuit boards. To be honest, the costs  for the work involved is amazing. If your anything more  than a caveman you have used both of these items.

Watch it Mr. Mod.  That overlator is awfully close to an ovulator.  This is a family forum.

They are not related to each other for useage.

.Millions and millions of people use the one on the right every day

cell phone on the right? 

 

left looks like a doorbell. Right looks like a phone base that fits on the wall from the hole pattern, or maybe an alarm clock.

The one on the left is a 120 volt Ground Fault Circuit Interrupter, GFCI,found in every kitchen and bath room.$16

On the right is  a wireless keyboard mouse. Note cut out for the wheel.$5.00 shipped.

I love "reverse engineering" [tearing things apart to see how they work].

If you want to see something amazing, look into a truck/car door lock actuator.
