How to build LED Tester Circuit Diagram - circuit diagram

You have to admit that these tiny electronic lamps are handy, and they last almost forever. Around 40 years after Nick Holanyak developed the first LED, they have become just about indispensable. Any self-respecting electronics hobbyist always has a few in his junk box. But before you use LEDs, it's a good idea to check them out. With a LED tester, you can even do it in the dark!.......

El temporizador (timer)El temporizador (timer)

Iniciamos el tutorial con un ejemplo real. Arma el circuito de la figura 1. Pulse momentáneamente el suiche y al soltarlo observe el brillo del led.Ahora cambie el C por uno de 470uF/25V y repita el proceso. Concluimos que el tiempo de descarga del C es mayor cuando aumenta su valor en uF. Ahora veamos la carga del C. Armamos el circuito de la figura 2. Con la ayuda de un tester ó multímetro mida el voltaje DC en los pines del C y observe como va aumentando lentamente su voltaje de carga. Aho.......

Stepping into firmware

Having had good experience with the Rapman's PIC32-based controller, I decided to stick with that MCU for my new printer. As I mentioned earlier, rather than buy a $1k+ C compiler from Microchip, I bought a much less expensive, full-featured BASIC compiler for the PIC32 {they also offer C and Pascal compilers} and a full development board from Mikroelektronika in Belgrade. Friday night, with the last of the z-axis brackets being printed on my Rapman and the 19 June exhibition in San Francisco co.......

9V Battery 5V Regulator Cap

For quick portable projects and temporary hacks, it is often faster to reuse a simple 5V regulator circuit than to integrate a power supply into the device design. My toolbox has an LED tester and magnifier light, so why not add a convenient 5V regulator cap to the collection? There are nicer ones on the market that have surface mount components, but half the fun of an electronics hobby is creating something basic in your own style. This double-decker board with flashing LED power indicator allo.......

Digital Soil Moisture Tester | Electronics For You Digital Soil Moisture Tester | Electronics For You

Here is a simple and compact digital soil moisture tester to check whether the soil is dry or wet. It can also be used to check the dryness or wetness of cotton, woolen and woven fabrics. For indication, the tester (see Fig.1) uses a number of LEDs driven by ubiquitous display driver IC LM3915 (IC1). [ ... ].......

How to build XTal Tester - circuit diagram

This is a simple XTal tester circuit. T1 and XTal have formed an oscillator. C1 and C2 are voltage divider for oscillator. if the XTal is safe, the oscillator will work well and its output voltage will be rectified by C3, C4, D1 and D2, then T2 will run and LED will light. The circuit is suitable to test 100KHz - 30MHz Xtal........
