When you hear a word “relay”, probably you think of mechanical relay that can be activated with electromagnet inside. All you need to apply some amount of current across relay coil to operate switch. This way you can control large loads with small signals. But there are some disadvantages of using mechanical relays – they aren't reliable, they wear off and are slow. So more and more they are replaced by electronic relays with no moving parts. These are called Solid State Relays (SSR) and can be purchased as blocks. If you have a pile of various electronics parts lying around, you can build a SSR relay and pay no money as these are quite expensive.

Follow the Solid State Relay schematic provided by electronics-diy and you will be able to understand and DIY Solid State Relay out of distinct parts. Once finished SSR can be attached to your project like other normal relay that has to switch high AC loads.

If you've been working on your very own Coil Gun, but you still having many obstacles, then you might be interested to check up this following Coil Gun project.

This emotional sedan began its life as a customary, gasoline-powered 1994 Geo Prism. Here are the modifications that twisted it into an emotional car: The gasoline engine with the muffler, catalytic converter, tailpipe and gas reservoir, were all severed. The existing legal transmission was left in place, and it was pinned in instant gear. A new AC emotional motor was bolted to the transmission using an adapter plate. An emotional controller was added to restrain the AC motor.

A series tray was installed in the mystify of the car.
