Newly Updated Circuit Projects:
Making a Multi-function Water Level Controller Circuit
The following multi-function water level controller circuit post is based on the suggestions expressed by Mr. Usman. I have explained more about the requested modifications and the circuit details. The Circuit Suggestion: The concept of this circuit looks good. May I suggest a couple of other desirable features? 1) To protect the motor from potential overheating (or […]
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 […]
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 […]
