The article discussed here provides a simple, cheap home theater system circuit that may be built at home and used for the desired purpose. Introduction The results from this circuit design are outstandingly rich and have the capabilities comparable with the costly hi-end types available in the market. Home theater systems are quite common nowadays […]
Newly Updated Circuit Projects:
Understanding Scalar (V/f) Control for Induction Motors
In this article I will try to explain how scalar control algorithm is implemented for controlling induction motor speed with relatively straightforward calculations, and yet achieve a reasonably good linearly variable speed control of the motor. Reports from many top market analysis reveal that induction motors are the most popular when it comes to handling […]
Light Activated Water Level Controller Circuit
The light activated water level controller circuit explained here has the advantage of being corrosion free and much reliable than the traditional moisture sensor type of water sensors. Circuit Operation One slight downside of this LDR based sensor is that the tank interior always needs to be illuminated by some kind of light source such […]
Modifying a Bluetooth Headset Device
In the previous post I explained regarding the internal circuitry of a typical Bluetooth headset, in this post we’ll see how a Bluetooth headset unit can be modified or “hacked” in order to make it work for other personalized applications. In the previous article I have explained how to break open a Bluetooth headset device and […]
Understanding Solar Panels
Solar panels are devices which are used for generating electricity from sun light. Solar panels consist of many individual photo voltaic cells arranged in series. Introduction Each cell is able to generate a small amount of voltage in response to the incident sun rays over its surface. Arrays of these individual cells are connected in […]
How to Connect 5mm LEDs to a 3.7V Li-Ion Cell
In this article I have explained regarding how to connect and illuminate a few 5mm LEDs using a 3.7V Li-Ion cell, normally used in cell phones. I keep receiving requests from the readers who seem confused with the connection details of 5mm LEds with a 3.7V Li-ion cell. The requests inspired me to write this […]
