Dаvid Jones through his Youtube channel EEVblog described in detail how to design a cheap soft latch power switch circuit, using one push button switch to toggle your circuit power on and off with the following design requirements: Zero power when off. One on/off switch....

One of the biggest problems you could face in your current/next project, is when you’re out of free inputs to use. Sometimes you can save a lot of inputs using some tricks, and there’re really a lot of them. In this blog post we’re going to know how you can use many push buttons...

DHT11 is a common humidity & temperature sensor. This sensor has a single wire serial interface with special timing diagram for the single wire interface. When the MCU sends a start signal, DHT11 sends a response signal followed by the humidity reading and then the...

Diode or P-channel MOSFET is what you need to protect your circuit from applying reversed voltage, according to a nice video published on Afrotechmods channel. Method 1:Diode The simplest way is to use a diode in series with main power supply. When you connect the power source...

Sanket Gupta pointed us to his latest article, on how to select an inductor and discuss about the various types of them. Inductors are two-terminal components used for filtering, timing and power electronics applications. They store energy in the form of magnetic fields as long as a...

aimtec.com has a basic article on how to limit inrush current using passive components. Inrush current or input surge current refers to the maximum, instantaneous input current drawn by an electrical device during its initial turn on. Power converters also feature high inrush...

Average Man Vs Raspberry Pi has a handy article on LiPo batteries. LiPo batteries – to fear or not to fear? Up until very recently, I was petrified. Whilst most other competitors at Pi Wars 2015 were happily using this angry and volatile battery technology, Average Man over...
