How to Build a Simple Industrial Delay Timer Circuits

In this particular publish we are going to go through two ordinary externally activated timer circuits for two various application requirements.   Talking about the diagram above the offered solenoid timer with reed switching can be viewed set up across a single timer/counter chip 4060. Provided that the reed switches are not activated, the pin12 […]

Snooze Delay Timer Circuit

In this article we learn how to make a simple Snooze Delay Timer Circuit using very ordinary components. When the Set switch is depressed the large electrolytic capacitor is charged via the limiting resistor (lk). This charge causes the BC109 to conduct which supplies enough base current to switch on the 2N1711 space and operate the […]

Dark Room Timer Circuit

 Working in a darkroom is always fraught with problems. You surely know Murphys Law of. . ., but Let’s not go into that here. Suffice it to say that normal lights cannot be used in a darkroom when photographs are being developed not even if you drop your glasses! The dark room timer circuit here […]

Simple Mutifunction Timer Circuit

A timer is practically unachievable without IC 555 or counter ICs along the lines of CD4029 or CD4060. The simple mutifunction timer circuit in this article takes advantage of an inverter rather for accomplishing the same duty. As revealed in the projected multifunction timer circuit, gate N1 together with C1, R1, VR1 and VR2 shapes 21 […]
