Extremely Low Frequency (ELF) Radiation Monitor Circuit
ELF stands for Extremely Low Frequency, which is an electromagnetic radiation generated by most of out household electrical equipment. Regarding the effect and severity of ELF fields on human health, debate remains heated. However, I believe there is enough data for us enthusiasts to adopt a conservative stance on the level of exposure we must […]
Understanding and Using a Piezo Transducer
In this post we try to investigate what transducers are and how they need to be configured in circuits while using them in a given application Understanding Piezo Transducers A piezo transducer is a device primarily used for converting an applied frequency to audible sound. It may be compared to a loud speaker, the only […]
3-Pin Solid-State Car Turn Indicator Flasher Circuit – Transistorized
Although, most of the car electronics have evolved into solid-sate versions, a turn indicator flasher unit is one device which still depend on a relay based design in many of the modern cars. Disadvantages of Relay Based Flasher There are a couple major disadvantages of a relay based electromechanical flasher unit: 1) First, these being […]
