A split core transformer (or non-invasive current sensor) is a form of current sensor that doesn’t require the existing power cable to be cut; instead this transformer clamps around a power cable. It measures the current by acting as an inductor and responding to the magnetic field around a current-carrying conductor. By reading the amount of current being produced by the coil, you can calculate how much current is passing through the conductor. This version outputs 50mA at 100A - which makes it great for building your own energy monitor to keep your power usage down, or even building an over-current protection device for an AC load. This sensor does not have a load resistor built in, so in most cases it will be necessary to place a resistor across the output to convert the coil’s induced current to a very small measurable voltage. ...

Have a 2.1mm DC barrel plug and a 2.5mm jack? Trying to plug the 2.1mm into a 2.5mm jack simply wont work, the pin diameter of the jack simply wont fit into the plug. This adapter allows the 2.1mm to fit a 2.5mm jack without cutting and soldering a different connector or buying a new power supply. . . ... [Read More]

Small metric hardware is a staple of building most electronics projects these days. This kit includes 10 M3 x 20mm Socket Cap screws and 10 M3 Nuts. The socket cap screw has a 2.5mm hex socket for use with a standard 2.5mm Allen Key or Hex Driver. ... [Read More]

As electronic components get smaller and smaller tweezers become more and more essential. These Anti-static and Anti-magnetic safe tweezers are great for working with small surface mount and through hole components. They don't strictly need to be used for electronic components; they also are great for building models and handling just about anything tiny. These tweezers are slightly smaller than our standard fine tip tweezers and fit a little better in tight areas due to their construction... [Read More]
