Turn any surface/wall/table etc into a speaker with a surface transducer. This type of speaker does not have a moving cone like most speakers you've seen. Instead, a small metal rod is wrapped with the voice coil. When current is pulsed through the coil, the magnetic field causes a piece of metal to expand and contract - and if it's pressed against a surface it turns the transducer into a speaker! Often these size transducers are pressed...

A button is a button, and a switch is a switch, but these translucent arcade buttons are in a class of their own. They're the same size as common arcade controls (often referred to as 30mm diameter) but have some nice things going for them that justify the extra dollar. First, they look fantastic, all 6 colors have a crystal translucent glossy look. Although they do not have LEDs built in, we're confident that sticking a diffused LED...

This navigation switch is an intuitive way to add 5 button's worth of interfacing with a single component. Inside is 5 switches: left, right, up, down and 'select' (pressing down), all with a common ground pin. The package isn't exactly on a 0.1" grid, but we found that you can push it into a breadboard with a little bending and it snaps in nicely.

When you need to switch a lot of power, P channel MOSFETs are best for the job. These P-FETs can switch over 60V and 25A (with proper heat-sinking) and are TO-220 package so they fit nicely into any breadboard or perfboard. Heat sinking is easy with TO-220s, but because of the very low Rds(on) of down to 70 mOhms (depending on the Vgs - check the datasheet) you can get away with no heatsinking for pretty high loads!
