This give backup to DSL modem and WiFi router. This circuit is with simple parts, easy to build and with low cost. Circuit Working: Parts List: […]
Inverter Circuits
Arduino Based Power Inverter Circuit
Inverter is a useful device in electronics, it changes DC (Direct Current) to AC (Alternating Current). In this project for Arduino Based Power Inverter Circuit we will make simple inverter using Arduino and it takes 12V DC and gives 230V AC. We used an Arduino UNO, an IC 7809, several transistors and a reverse-connected transformer […]
Designing an EL Wire Power Supply Circuit
EL wire need special power and normal battery DC cannot power it. EL wire is thin, bright and flexible and people use it in art projects, clothing, signs and decorative lighting, also it requires a high-voltage AC supply of 100 to 200V at a frequency of 1–5 kHz. So, need EL wire inverter circuit where […]
Simple 20 Watt Fluorescent Inverter Circuit
Imagine we have normal car battery and we want to use it for fluorescent light, but the battery voltage is too low and it does not work like this. So we use special and Simple 20 Watt Fluorescent Inverter Circuit like a magic box and this box has transformer, transistor and other parts which change […]
220V Inverter Circuit using 2N3055 Transistors
This article show how to make a strong 220V Inverter Circuit using 2N3055 Transistors, which can change 12V battery like car battery into 220V electric for home. Also, it is easy to make and does not need many parts, and work very good. WARNING: But be very careful, homemade inverter can be dangerous always check […]
