Simple LED Torch



This is a simple LED torch.The specialty of this circuit is this circuit helps you to  operate your torch for many hours.Here I have used 2W LED.Through this circuit you can light up your torch about one month.Here I have used a common IC 7555.This circuit operates with 6V But if you like to operate this circuit with 9V or 12 V you have to change R3 .If you use 9V use 470 Ohm.If you use 12V use 560 Ohm.








Note


# Build this circuit on a PCB
# Don't use NE555 instead of 7555
# Use alkaline batteries

Low-Side MOSFET Drive Circuits and Techniques - 7 Practical Circuits

Image
In many circuits, it is necessary to use MOSFETs for switching. In many cases, the MOSFET drive signals are generated by microcontrollers. In other cases, they are generated by ICs – PWM controllers, timers or any IC in fact. However, MOSFETs cannot always just be connected to the drive signal and be expected to work properly. Due to the construction of the MOSFET, driving it is not the simplest of tasks, especially for beginners. There are many users who regularly ask for help on MOSFET drive related issues or problems on different blogs, websites and forums. So, here I will show some MOSFET drive techniques/methods for MOSFETs configured as low-side switches. Before I head on to MOSFET drive, let me just tell you what a low-side switch is, in case you don't know. When the MOSFET (that you're using as a switch) sinks current, it is a low-side switch. The load will be between the drain and +V supply. The source will be connected to ground. Gate will be driven with respect to gr

Using the SG3525 PWM Controller - Explanation and Example: Circuit Diagram / Schematic of Push-Pull Converter

Image
PWM is used in all sorts of power control and converter circuits. Some common examples include motor control, DC-DC converters, DC-AC inverters and lamp dimmers. There are numerous PWM controllers available that make the use and application of PWM quite easy. One of the most popular of such controllers is the versatile and ubiquitous SG3525 produced by multiple manufacturers – ST Microelectronics, Fairchild Semiconductors, On Semiconductors, to name a few. SG3525 is used extensively in DC-DC converters, DC-AC inverters, home UPS systems, solar inverters, power supplies, battery chargers and numerous other applications. With proper understanding, you can soon start using SG3525 yourself in such applications or any other application really that demands PWM control. Before going on to the description and application, let’s first take a look at the block diagram and the pin layout. Pins 1 (Inverting Input) and 2 (Non Inverting Input) are the inputs to the on-board error amplifier. If you a

Simple MW Transmitter Circuit Diagram

Image
Today I'm going to give you a simple MW Transmitter.This transmitter can be operated with 9 v power supply.Here we have used common transistor BF494B.Here we have used MW antenna coil you can use the 8 ohm speaker to speak that means here the speaker does the work of the mic.To get the maximum result build this on a pcb and don't supply power without connecting the antenna.             Note:   Don't missuse this circuit            you can send signals up to 500M
