Magnetic Levitation with Arduino

Hello friends this is another magnetic levitation project done with arduino. The suspended ball is a permanent magnet. Distance of the ball from the electromagnet is measured by a hall effect sensor placed under the coil. The digital control loop is a PID algorithm that modulates a PWM output to energize the electromagnet through a […]

Wireless Charging

Nokia has come up with a “wireless charging” method. They call it a wireless charging but it is just the other way of removing your power pin socket from your phone and getting high attention in media. Not going into the marketing strategies of Nokia wireless charging for Lumia 920 we better look at the technology […]

Home made Magnetic Levitation

Hello guys here is another home made magnetic levitation trick by Genius Devil (Oliver).He just made this awesome project within half hour. he has found out that there is a neodyme magnet used in hard disk that possesses  Diamagnetic phenomena.As this is just a half hour mini project by (Oliver) he has not given much detail of this […]

Wireless Power Transfer Project

Wireless Power Transfer was invented by Nikola Tesla. He demonstrated this from his laboratory in Colorado Springs and achieved a transmission distance of over 25 miles. The theory behind this is simple. You take two identical secondary coils, use 1 as the transmitter and one as the receiver. These form a “tuned system”, whereby signals […]

Home made Coilgun

This is really a nice article about home made coil gun.Written by Genius Devil (Penguin) He is fond of high voltages and high currents so can be called man with POWER. (He has already designed a Marx generator that can produce voltage up to 150kV just from simple components) He has made this design with […]

Magnetic Field Guided Robot

We have seen many of the line followers till now but they suffer with most of the lighting issues; if you are not given proper surrounding your line follower can’t detect the deference between line and background. But this in ingenious solution developed by Genius Devil ( Philippe) he made a “current wire guided robot”.He […]

Home made magnetic levitation

Here is the cool guide about how magnetic levitation work and how you can make your own levitating magnet just from your old hard disk drive. The Genius Devil (Penguin) had a hands on experiment with magnetic levitation and he found that there is another type of magnetic material called Diamagnetic material which repels both the plate of […]
