How to Build a Voltage Regulator for $3

Here’s a straightforward way to build your own “Runtz” type voltage reducers so that you can use your 6 volt gauges on your 12 volt system. The regulator is based on the LM7806 integrated circuit, which is able to reduce voltage while maintaining a constant current. Use one regulator for each gauge; this allows youContinue reading “How to Build a Voltage Regulator for $3”
