Wire strippers

A wire stripper is used in removing insulation from around a wire or cable. Sure, you can do this with a pair of scissors, wire cutters or even a utility knife, but using a tool specifically designed for this purpose makes life easier if you work with wires often. Here are three wire strippers I

Battery packs for power tools

The best part about cordless drills is well, they are cordless! The worst part of them is that they have limited battery life. There are different types of battery packs for different tools. There are different voltages and different capacities (mAh or Ah). The ampere-hours (labeled Ah) denote the maximum amount of charge the battery

Differential oscilloscope probes

By far the most used oscilloscope probes are the passive 10:1 attenuation probe. Next step in probe categories are active probes. Active probes succeed in practically eliminating reactive loading of the circuit under investigation by means of a small solid-state amplifier in the probe body adjacent to the tip. There are two main classes of

RLC measurements

This article is about measuring resistance, capacitance and inductance. The measurements described here talks about measuring components that not wired into any circuit. Resistors, Inductors and Capacitors are the most commonly used passive components in almost every electronics circuit. Out of these three the value of resistors and capacitors are commonly marked on top of
