Just thought I'd share a few pic's of my latest amplifier project. It utilizes a TDA2004 and has a cool stereo 10W per channel. It runs off 12V and, amazingly, it works! The sound quality is pretty good, but there is the tiniest amount of hum present.

NOTE: THE FIRST THREE STEPS ARE AN INTRO. THOSE OF YOU WHO ALREADY KNOW ABOUT LED's SHOULD SKIP TO STEPS 4 AND 5 FOR THE TIPS. I've been noticing that a lot of people (not people on instructables, but people interested in electronics in general) don't really know about LED's.

Servos can work really well as drive motors for a small robot. Their motion is relatively precise and predictable, and they operate on the same voltage as most microcontroller electronics, allowing you to build a simple robot without any additional motor control circuitry.

An anonymous reader requested a hack today to solve a particular kind of kitty problem. Specifically, the reader wants to know if there's a way to have a cat door that grants access to particular cats while restricting entry or exit for others.

I made an application that uses libusb-Win32 and PPJoy to map the Sony Sixaxis into a windows joystick with the accelerometers working and mapped.

In 1985, Wim van Eck published a paper which described how the state of a CRT monitor could be reproduced remotely based on the device's electromagnetic radiation.

There's an article over on the WiiLi Wiki that goes into great detail describing how to translate 3D accelerometer measurements into an estimation of the position, rotation, and velocity of a device like the Wiimote.

Before you buy a replacement battery for your dead Roomba, you might want to consider rebuilding the pack yourself. You can get a couple of 6 cell Sub-C NIMH packs for less money and more amp hours than the stock battery.

The German translation isn't perfect, but this site describes a privacy product that defeats security cameras. A simple IR LED array in a headband is able to oversaturate the pixels in the camera's CCD to the point where even adjacent pixels are effected, shrouding the wearer's face in a white halo.
