Electronics Magazine Tells To Make Analogue Watt Meters And Clap-based Volume Control

The technology in electronics trade is changing at fast pace

. Getting updates about the new progress has become the need to perform better. Generally we do not have much time to go through books or journals to brush up our knowledge but electronics magazine portals are helping in great way by offering periodic bite. There are many online portals that help the technology smart professionals in many ways by giving latest updates about new electronic projects and circuits. Online portals like Electronics for you' have become the need of hours because juts few minutes on such portals keep us ahead of others. The circuit lab style sections are focused on the new circuits designed for generating new useful gadgets by self or to reduce the production cost of gadgets. Do it yourself such sections additionally contains the information regarding the DIY projects nevertheless the circuit lab is more optimized for the electronic circuit of small devices of importance like Clap-Based Digital Volume Control or power meters.

Recently, in an online electronics magazine's circuit lab section, there appeared a special gadget named Clap-Based Digital Volume Control'. This amazing control tool offers volume control facility at 4 levels with the help of claps. Each clap raises the volume of audio device. After last and 4th clap, volume level returns back to first level that is the minimum volume level. The article is available with well outlined circuits. Every part is well described with numeric classification. The circuit of Clap-Based Digital Volume Control consists of 4-stage counter, resistive ladder network , level detector, microphone and four analogue switches etc which are easily available in our stock.

The other write up in circuit lab section was about Analogue Watt meters. The write up provides the details about its working and circuits. It is used to measure on the spot active or reactive power (P) in any unbalanced or balanced single phase or 3-hase electric circuit. This device contains a separate converter and analogue indicator. The modular converter is fitted for the DIN rail. Different from voltage or current measurement, the measurement of power is the product of voltage (V) and current (I) flowing via dissipative circuit. In linear-moving coil meter, the deflection on the pointer is relative to the current flowing through the meter. It is also relative to the duty cycle of actual waveform. The degree of deflection is relative to the product VI.

Analogue Watt meters and other such small value devices are much of use in production houses as well as we can incorporate these to complete out DIY projects. Electronics magazines have become a boon for the students, innovators and engineers.
