If you are a fan of David Letterman, I'm sure you've seen and heard his nutty and often hilarious top 10 lists. He has become famous for them and they have been often imitated but never quite aptly duplicated by many around the world. I have no intentions of trying to claim or ever hope to be as funny as Letterman but I would love to create a top 5 list of why you need a new auto sound system. The sad part is that some of this may ring true for many, if not, I bet it will at least make you smile. 5) You really hate your neighbors and secretly hope that enough loud, late night thumping from your car will convince them to move. Admittedly not the kindest reason for the need of a new auto sound system but if you've had some of my previous neighbors I am fairly certain that it isn't too bad of an idea. Just be careful not to shake too much or they may be leaving part of their automobiles behind. 4) Because you saw it on Ebay and like Weird Al Yankovich you just can't se...

The BA3822LS BA3822FS BA3823LS and BA3824LS are monolithic, five-point stereo graphic equalizer ICs. Each IC has two channels, and the five center frequencies for each channel are independently set using external capaci- tors. These ICs feature a wide operating power supply voltage range (VCC = 3. 5V to 14V), and are available in compact 24-pin SZI visit page. P and SSOP packages, depending on the type. This makes them an ideal choice for home stereo systems, Radio cassette players, and car stereos. The difference between the ICs is the amount of boost and cut control.

Chris from PyroElectro.com has a great article about a do-it-yourself radar system build with PIC18F452. It’s a great hobby project although the schematic is very complicated. This project uses three main devices to create the personal radar system. The IR Range sensor gives output, the pic microcontroller processes it and then displays the output on the led array.   Infrared Radar Circuit Schematic  The goal of this project is to create a working ir radar system. The system will only be required to measure close proximity at an angle of 90 degrees as seen in the example above. The range of system is roughly 4-30cm, 20-150cm & 1m-5.5m depending upon which sensor you choose to use. [ ] source by :circuitsstream
