Ohmmeter – Simple Resistance Measurement

Measurement of resistor values in circuit configurations are required to be made often, as these might have changed in value due to (more…)

Here is a Neon Flasher circuit (untested) for a user request at Circuits FAQ. This can be built into a switchboard or (more…)

This is a Simple Voltage Doubler to boost 3V battery voltage to power some low-power 5V circuits. In needs a Clock input (more…)

This was done in my early days, i have upgraded it, it ought to work, reduce the number of transistors to make (more…)

This is a constant current source using a FET. This is the most simple replacement to series resistor to limit current. The (more…)

Voltage multipliers are used to obtain low current high voltage, from an existing AC Source. Step up transformers can be used, but (more…)
