Quick Continuity Testers from Dollar Store Parts

Description

How fast and how cheaply can test equipment be made? Two can be made for less than 5 dollars, an hour of time and a glass of wine with my sweetheart. A great Wednesday night.

“Real parts” like a battery holder, mini buzzer and alligator clips along with wire with some solder can be tracked down, but if you're not buying in bulk that can be oddly expensive. Biggest tip, keep the circuit under 3 Volts. For testing delicate circuits, it will be time to uplevel with some of the fancier circuits in the links.
