Printed Circuit Boards (PCBs) are a great way to make your circuit more durable and permanent by soldering your components directly onto a pre-routed board designed for the type of circuit you are making.
When transferring a circuit from a breadboard to a PCB, I recommend leaving the breadboard version intact and using duplicate parts to populate the PCB. That way you can always refer to the breadboard if you forget something.
There a bunch of great PCBs that feature the 40106 chip. I’ve collected a few of my favorites below.
