The circuit provided in this article shows you a simple way of building a useful liitle inverter that’s easy to build and yet provides the features of a pure sine wave inverter. The circuit can be easily modified for getting higher outputs. Introduction Let’s begin the discussion about how to build a 120 Volt, 100 […]
Newly Updated Circuit Projects:
LED Lamp Circuit for Motorbike Headlamp
In this post I have explained a simple 21 watt LED lamp circuit module which can be used as a direct replacement for a standard halogen lamp used in motorcycles headlamp. LED vs Halogen Lamp The proposed “halogen” LED lamp replacement module image can be seen below: Conventional filament type halogen lamp is shown below: […]
Adjustable Timer Circuit Using IC 555
IC 555 adjustable timer explained here can be adjusted from any time delay 1 second to 3 hours for operating any load through a relay control The produced time delay is fully adjustable and the user has the freedom to set the time period as desired. There are many ways of making simple timer circuits […]
How to Build a 220V DC Inverter UPS Circuit
In this post I have explained a simple 220 V to 220V DC online UPS inverter circuit. The idea was requested by Mr. Taiye. Technical Specifications I intend to build a 1000 watt UPS with a different concept (inverter with high voltage input dc). I will use a battery bank of 18 to 20 sealed […]
LED Driver Power Supply Circuit Using Dimmer Switch
In this post I have explained an effective and efficient high current compact LED Driver power supply using a dimmer switch gadget. In one of my other posts I discussed a high voltage transformerless power supply circuit that used a triac for controlling the capacitive output, however since the concept involved shorting the capacitive output […]
Transformerless Constant Current LED Driver Circuit
In this post I have explained how just a single IC MBI6001 can be used as a transformerless constant current LED driver circuit for illuminating a chain of many LED in series. The MBI6001 series of ICs are designed to work with mains AC inputs and convert it into a lower voltage DC output which […]
