Before we can really begin addressing how a motor works, lets focus on what a motor does. A motor uses electromagnetism to create motion, converting electrical energy into mechanical energy. Magnetic fields produce physical force that can move things. Every magnet has a magnetic field with a north pole and a south pole.
If you try to push the north poles of two magnets together, they will repel each other. The same thing happens if you try to push two south poles together. An electric motor uses the attraction and repelling properties of magnets to create motion. In an electric motor, the electromagnet is placed on an axle so it can spin freely inside the magnetic field of a permanent magnet.
Motors are classified by having the following properties: How to Make a Full Auto Airsoft Minigun [Halo Inspired Mobile Turret] This is a type of cloud airsoft gun - named so because of how the pellets are blown around the reservoir before being fired out the barrel.

Since there is nothing mechanical to get in the way of the workings of this gun the rate of fire is extremely high, an estimated 50 rounds per second. It would make a great airsoft turret to be mounted on the defensive wall of a home base. The price of materials is just over $50 assuming the builder already has PVC primer and cement.

A Bandsaw box KIDS can make. I've tried all sorts of box projects with kids.
Some are pretty good, some not. What most kids want is a small box with drawers in it. The bandsaw is perfect for this but most designs I've tried are really tough for kids to do.

Sound absorption panels trap acoustical energy (sound) and prevent it from reflecting off of the surfaces they cover. The panels are used to eliminate echoes and reflections that muddle or color amplified music and speech. *Note that choral music, piano, orchestral instruments, group singing, and pipe organ benefit from reasonably reverberant acoustics, with many reflective surfaces.
Suitable applications for sound absorption panels include: Open Source Soldering Iron Driver. How-To: Theater or studio acoustic treatments. Have you been yelled at for watching your latest Superbit DVD "too loud" by your mom / dad / child / spouse / neighbor?
