A joule thief circuit is basically an efficient, self-oscillating voltage booster circuit, built using a single transistor, resistor and an inductor, which can boost voltages as low as 0.4 V from any dead AAA 1.5 cell, to much higher levels. Technically it may seem impossible to illuminate a 3.3 V LED with a 1.5V source, […]

Build this Simple Solar Egg Incubator Circuit
In this post I am showing you one very nice and simple solar powered egg incubator circuit project. Many people ask me bro how to upgrade simple incubator with solar charger and battery backup so egg will not spoil when main power line is going off. In rural areas power cut is major problem for […]
SMPS LED Bulb Circuit with Dimmer Control using IC IRS2530D
Today we are going to look into a very high efficiency resonant-mode off-line LED driver circuit. It is based on a very popular Infineon article which uses the IRS2530D DIM8 controller IC. Normally electronic ballast technology is used for old fluorescent tube lights, but here Infineon used the same concept to drive high power LEDs […]
Camper, Motorhome Battery Charger Circuit
In this post I have explained a battery charger circuit specifically designed for camper and motorhome applications, so it can serve as an effective camper/motorhome battery charger circuit operating through any shore power supply source. The idea was suggested by “music girl”. Battery Charger for Motorhomes Based on this customized battery charger circuit I would […]
SG3525 Full Bridge Inverter Circuit
In this post we try to investigate how to design a SG3525 full bridge inverter circuit by applying an external bootstrap circuit in the design. The idea was requested by Mr. Mr. Abdul, and many other avid readers of this website. Audio/Video Representation Why Full-Bridge Inverter Circuit is not Easy Whenever we think of a […]
How to Build a Simple Egg Incubator Thermostat Circuit
An electronic incubator thermostat circuit shown in this article is not only simple to build but is also easy to set and acquire exact tripping points at various different set temperature levels. The setting may be completed through two discrete variable resistors. How Incubators Work An Incubator is a system where bird/reptile eggs are hatched […]
