How to make a Tesla Coil (DIY)

Introduction Nikola Tesla invented the Tesla Coil in 1891. We use these coils as high energy electrical transformers. We can use it to produce high-voltage, low-current, high-frequency alternating-current electricity. He used these circuits to conduct innovative experiments in electrical lighting, phosphorescence and X-ray generation. Along with high frequency AC phenomena, we can use Tesla coil for electrotherapy, and the transmission of electrical energy …

LED Dimmer using IC 555 | DIY

We use LED lights almost everywhere to light up the space or a room. But sometimes, we find it difficult to deal with the brightness in the night time. So, in this project, we will see how to make a LED dimmer using IC555. We can acheived control over brightness of these LED lights according to the surroundings.
