Nos receptores de rádio, antes do advento dos sintonizadores digitais, eram utilizados capacitores variáveis para sintonizar mecanicamente as emissoras (figura 1). Ainda hoje, muitos rádios o fazem desta forma. Dependendo da qualidade do capacitor variável e da forma e intensidade de uso do aparelho, este componente costuma apresentar defeitos bem específicos. Apresento aqui algumas técnicas…
Nuts & Volts Magazine is written for the hands-on electronics hobbyist, design engineer, technician, and experimenter.
The design "completely eliminates bounce at the output of the encoder and provides 100 per cent reading accuracy," its creator claims.

In this tutorial I will describe how to drive a 7 segment module using a 4511 – BCD to 7 Segment Latch/Decoder/Driver. First we need to familiarize ourselves with the 7 segment module. These modules are made up of 8 LEDs, 7 of which make an “8” pattern and 1 for the decimal point. Using the 7 segments, you can...
![How to identify 18650 cell capacity by color / code and how to tell fakes from real – [En]](https://i.pinimg.com/originals/72/af/3e/72af3e7f729bf9fdfd54fa76c9604d2f.jpg)
Before anything, I'll briefly explain what 18650 cells are and what uses they may have. I have worked a lot with 18650 cells and I used them for pretty much anything that needs power. Basically, they are Li-Ion cells, that means they have the same overall parameters as a now-days phone battery. Their nominal voltage…
If you want control the DVD or TV/AV system that located in your living room via the remote control when you sleeping in your Bedroom. this IR extender will achieve this for you. Basically, it works as a repeater that moves the IR signal to a different location. This is an improved IR remote control extender circuit. It has high noise immunity, is resistant to ambient and reflected light and has an increased range from remote control to the extender circuit of about 7 meters. It should work with any domestic apparatus that use 36-38kHz for the IR carrier frequency.
