Simply elegant LCR bridge

The balanced bridge described in this article measures capacitance from 1 pF to 10 µF, resistance from 1 Ω to 10 MΩ, and inductance from 1 µH to 100 µH. Ideal for checking the values of non-marked or otherwise non-identifiable components, the instrument costs next to nothing, and can be built from parts from the junk-box.
