The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

catches a person ’s bad dreams. The unique part of my dream catcher is that‚ the formation on the strings formed a Transformer Type of head. By no means‚ I never actually intentionally shape the way it was and I find it kind of amusing. This project took me about a week to finish. I don’t think I want to change anything about it because I pretty much like the transformers myself even if the cartoons are guys. It just reminds me of my childhood every time I catch a glimpse of it. I would love

we are providing a DC fan that runs through wireless power. This project is built upon using an electronic circuit which converts AC 230V 50Hz to AC 12V‚ High frequency. The output is fed to a tuned coil forming as primary of an air core transformer. The secondary coil develops a voltage of HF 12volt. Thus the transfer of power is done by the primary(transmitter) to the secondary that is separated with a considerable distance(say 3cm). Therefore the transfer could be seen as the primary transmits

CCTV VIDEO TRAINING MANUAL Someone once said‚ "Knowledge is the key to success". This rule also applies to the installation and maintenance of CCTV camera equipment. Have you ever installed a CCTV camera system and then had to go back to solve a problem that was overlooked. A basic understanding of CCTV video signals‚ can save you hundreds of man hours‚ improve customer relations and increase job profitability all at the same time. This manual will discuss problems and solutions for CCTV camera

Optocouplers vs. Pulse Transformers In isolation applications where one needs to pass signals in presence of transient or continuous high voltages‚ reject extreme noise‚ and break ground loops‚ optical (optocouplers) and magnetic (pulse transformers) coupling isolation are often used. However pulse transformers are much more difficult to design with relative to optocouplers. When dealing with pulse transformers‚ the load becomes more critical than with any other type of transformer. Leakage and primary

WIRELESS POWER TRANSMISSION Abstract: We are implementing new concept in our project. We are going to transmit the electrical energy without wire. It is not easy concept. Here power is transmit from one place to another place using electromagnetic induction or laser concept. Wireless energy transfer or Wireless power is the transmission of electrical energy from a power source to an electrical load without interconnecting wires. Wireless transmission is useful in cases where interconnecting
