Need a USB jack for charging or powering a project, but don't want to lug around a computer? This switching supply gives a clean regulated output at up to 1000mA! 110 or 240 input, so it works in any country. The plugs are "US 2-prong" style so you may need a plug adapter, but you can pick one up at any hardware store for a $1 or so. This adapter was specifically designed to provide 5.25V not 5V, but we still call it a 5V USB...

Need to add analog inputs? This chip will add 8 channels of 10-bit analog input to your microcontroller or microcomputer project. It's super easy to use, and uses SPI so only 4 pins are required. We chose this chip as a great accompaniment to the Raspberry Pi computer, because its fun to have analog inputs but the Pi does not have an ADC. We have a tutorial and code example for wiring this chip to a Raspberry Pi

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 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 up...

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!
