1.5V to 12V DC Converter Circuit Diagram for LEDs
The post provides interesting information regarding the making of a 1.5V to 12V converter circuit using a couple of transistors and an inexpensive coil. The idea was requested by Mr. Keith. The Circuit Request I found your blog and have searched for an answer to my question but I’m just not finding it…. What I want to do […]
Temperature Triggered DC Fan Speed Controller
This fan speed controller works by sensing the temperature of the engine and is accordingly used for the triggering. As the temperature increases so does the speed of the fan motor and vice versa. Circuit Operation Operation of the proposed temperature controlled fan may be understood as follows: The speed of the DC motor alters […]
DC Power Controller Circuit
In this post I have explained a DC power controller circuit which can be used for controlling the power of motors and lamps with maximum efficiency. By Sangeeta Naik How MOSFETs conduct to Handle Power Efficiently A minimum amount of power is lost whenever a power transistor (BJT or MOSFET) is in the turned off […]
3 Simple DC UPS Circuits for Modem/Router
In the following article I have explained 3 useful DC to DC uninterruptible power supply circuits or DC UPS circuits for low DC to DC uninterruptible power applications The first idea below presents a DC UPS circuit can be used for providing back up power to modems or routers during mains failures, so that the broadband/WiFi […]
Temperature Controlled DC Fan Circuits
Have you ever turned up your amplifier all the way, either at a party or just for fun? You may have noticed that “it gets hot” and thought that a fan would be useful. However, at low listening levels, you can hear the fan running. With this circuit, the fan will be automatically controlled by […]
