In this post I have explained a beacon indicator circuit for combine harvester grain tanks. The idea was requested by Mr. John Bosch. Circuit Objectives and Requirements I would like to retrofit the rotating beacon grain tank level indicator system shown below, to my older combine harvester. The particular part of the system I want […]
Newly Updated Circuit Projects:
Simple Faraday Flashlight – Circuit Diagram and Working
In this article I will show how to construct a Faraday flashlight circuit using only a coil/magnet assembly which requires no battery. It’s not free energy, but it converts oscillatory motion to electricity, which can power the flashlight for a couple of minutes. This flashlight will be useful in emergency situations where no access to […]
How to Add a Dimmer Facility to a LED Bulb
In this article I have explained how to make an LED dimmer circuit for enabling a dimming facility to any mains operated LEDs bulb. Update: [Using Capacitors, it Works] If you think PWM dimming control might not work for commercial LED bulbs, then the best method is to use series capacitors, which might just do […]
Simple LED Circuits
In this post I have explained how to build a few interesting LED circuits, and also learn how to connect LEDs correctly in a circuit. LED stands for Light Emitting Diode, which is actually a semiconductor diode which has the property of emitting light, when current is passed through it in the right direction, or […]
Solar Stud Light Circuit
In this post I am going to explain solar road stud light, what is it? How do they work? And how can we construct our own. In this post we will see the following: What are road stud lights? What are active and passive solar road stud lights? Circuit design and diagram. Flashing stud lights […]
LED Star Circuit
This circuit can be used like a tree ornament, however the LED star circuit explained here has a variation; it’s completely electronic and it provides the impression of an exploding and imploding 6 arm star. A block diagram of the circuit can be seen in the Fig. 1 below, configured using 3 components: oscillator, counter, […]
