Ingenuity reins when access to expensive tech is shunned or restricted. You may find this alternative shunt resistor useful when the amps to be measured exceed the capacity of your multimeter. Many digital multimeters (DMM) are designed to handle up to 10 amps. You may need to measure a 30A solar array or a 800A… Continue reading DIY Shunt Resistor Increases Amp Current Limits of MultiMeter DMM

R-Value of your Hot Water Tank
Advertised vs. Empirical If you would rather measure, than be given, the R value of your system, you will need to measure temperature. This method of using standby heat loss to arrive at the empirical R value can be applied to many different systems, but here a tank type water heater is measured. Measuring resistance… Continue reading R-Value of your Hot Water Tank
