The humble cable assembly

In a project, the major focus is on active components, circuit design and software, in that order. However, what we tend to overlook is the humble cable and connectors that link all the components together. Nonetheless, along with the more glamorous components, the humble cable assemblies also define the success and reliability of your project. Active devices and test equipment, being very tangible, always seem to command greater respect compared to the attention bestowed on the almost invisible Read more [...]

Why Does An Inductor Need A Fly-Back Diode?

An inductor usually stores energy when current flows through it, and releases it once the current flow stops. When the power supply to an inductor is suddenly reduced or removed, the inductor generates a voltage spike, which is also referred to as an inductive fly-back. Any current flowing through the inductor cannot change instantly and is limited by the time constant of the inductor. This is similar to the time constant of a capacitor, which limits the rate of change of voltage across its terminals. Read more [...]

Goodbye breadboard! Hello Circuit Scribe!

Can you imagine using a rollerball pen and paper to create a fully functional circuit? That day is almost here. The Circuit Scribe works just like a regular ballpoint pen except that it is filled with a special non-toxic conductive silver ink that creates functional hand drawn circuits. The special conductive ink dries instantly. The Circuit Scribe will be a great tool for people who feel overwhelmed with learning about using an actual circuit board. It will also be a great tool for experienced Read more [...]

What is a heatsink?

When current flows through a resistor, part of the electrical energy is converted into heat that gets dissipated into the surroundings. If the heat generated is not quickly removed, it can permanently damage the electronic circuit. Heatsinks are devices that are capable of removing the heat from electronic devices and speedily dissipate it into surroundings. Heatsinks can be passive or active devices. Passive heat sinks consist of fins made generally of aluminum that provide a large Read more [...]

What is Transistor-Transistor-Logic – TTL?

TTL or Transistor-Transistor Logic is a type of digital circuit that is made from BJT or bipolar junction transistor along with resistors. Both the amplifying function and the logic gating function are carried out through transistors, thus the name transistor-transistor logic. TTL is used for many applications like industrial controls, computers consumer electronics, test equipment, synthesizers and more. The TTL designation is also used in some places to imply ‘compatible logic levels’ Read more [...]
