. Un amigo me pidió que le hiciera unas "Shift Lights" para su coche de competición. Son luces de cambio, es decir, según las revoluciones motor, se van encendiendo progresivamente. Es un coche antiguo y he sacado la señal del distribuidor. Disponía de un sensor Hall (conmuta con masa para dar la chispa. Está en serie con la bobina). La entrada al pin 2 (int 0) la he protegido con una resistencia en serie de gran valor y un zener de 5V1 (recordad que está en serie con una bobina). A parte.......

Zener diodes may be used in a variety of ways - for example, zener diodes may be used as a voltage reference element. They are also used to limit voltages. Discovercircuits.com is your portal to free electronic circuits links. Copying content to your website is strictly prohibited!!!

An op amp combines with strategically placed zener diodes to yield a process-control circuit that has positive- and negative-going hysteresis bands.

Smoke detectors are generally used in advanced alarm systems. Most of this professional devices use gas-detectors, ionization rooms or radioactive elements as sensors. In this circuit we are not using any of this complicated components. Instead of these, we are using two LDRs and one LED. LM1801 special-purpose IC ,which is designed especially for smoke detectors, provides us building this circuit by using the minimum number of components. It includes one internal zener supply, two reference .......

The high power "zener diode" circuit presented here can be used for obtaining a highly accurate, temperature and voltage stabilized outputs from high current sources, safely. The low power zener diodes that we normally use in electronic circuits are specified to work with low currents, and therefore cannot be used for shunting or stabilizing high current supplies. Although higher rated zener diodes are available, these could be relatively expensive. Nonetheless, it is actually possible to make a.......

Though the 555 driver i ve been using is quite good in running the flyback, however the MOSFETs were easily heated up . I ve broken about 3-4 MOSFET since i ve been using it. Therefore, when i was searching for a more robust flyback driver in order to use it as my tesla coil power supply afterwards, i realized that zero voltage switching (ZVS) flyback driver can give high voltage without heating the MOSFET too much ( sometimes even none!). Hence, i turned to ZVS from that instance. The most popu.......

Here the low power 12V transformerless power supply circuit with full-wave rectification. A lot of circuits could be powered straightaway in the electric mains using the support of a series capacitor (C1). The problem with this method is the fact that typically only one half cycle of the mains wave-form can be used to deliver a DC voltage. An obvious option is to wo.......

This is the Analog front end of the 80C39 Process Controller. The analog input is protected by a Zener barrier, low leakage. You could use clamping diodes too. The non-inverting low-offset amp offers high input impedance. After further amplification it reaches the VCO LM331. The pulse train from the VCO reaches the uC port and is gated and measured by the MCS48 firmware. The voltage is deduced ........
