The LM311 is a versatile, fast voltage comparator with multiple capabilities. Its output stage is “open collector” and “open emitter,” allowing for various configurations. It can directly control relays and its output can be compatible with several logics, including TTL. Technical Specifications and Datasheet Here are some of the technical specifications of the LM311 comparator […]
Newly Updated Circuit Projects:
Proximity Detector using Hall Effect Sensor Circuit
This proximity detector circuit uses a Hall effect sensor to detect the approach of a magnetic object, such as a magnet fixed to the frame of a door. The application is simple, but widely used. The use of a Hall effect sensor solves many problems that arise when one wants to detect the opening of […]
Anti-Corrosion Probes for Water Level Controller
In this post I have explained a few interesting methods of constructing anti-corrosion probes for water level sensor and controller circuits by using alternating supply across the probes. Using Bridge Rectifiers (New Update) This simple anti-corrosion probe idea using bridge rectifiers happened to strike me recently and I decided to post it here for you […]
Parametric Equalizer Circuit
In this post we talk about a parametric equalizer circuit which can be used to enhance a music output to outstanding levels, much better than any standard graphic equalizer output. Advantages The main advantage of a parametric equalizer is that it allows you to modify the frequency and the “Q factor” across a wide range while also […]
Windshield Washer Fluid Indicator Circuit
In this article I have explained a permanent indicator of the windshield washer fluid level. Knowing that electronics do not mix well with liquids, instead of using a float gauge system, we have devised a completely different operating principle for you. The operation of our circuit is based on timing the duration of the motor’s […]
BT169 SCR Datasheet [200 V, 0.5 A SCR]
The BT169 is a thyristor or SCR (Silicon Controlled Rectifier) that is commonly used for switching applications in low-power electronic circuits. It can be used for small signal, low current applications. Its size is very small just like a BJT. Here are the full technical specifications of the BT169: Electrical Specifications Pinout: The BT169 SCR […]
