This door bell chime project provides the schematic and the parts list needed to construct a very simple wired door bell alarm that you can place on the door of your house. It is a very low cost and affordable project that every beginners to electronic design can hands on. Constructing this project will help the beginners to electronics to understand one of the applications of 555 timer that is configured in an astable mode. This project uses a 555 timer integrated circuit, a speaker, 5 resistors, 4 electrolytic capacitors, 1 ceramic capacitor, 3 diodes, 1 push-button switch and 9 V battery as power supply. <A HREF="http://ad.doubleclick.net/jump/electronicsprojdesign.GSIAN;sz=300x250;ord=123456789?"

I will now go against my own mantra...It can be done...but it shouldn't be. You will come across many videos and articles that will suggest that to build a burning laser all you need to do is unscrew the end of a maglite, remove the bulb, push the pins of a laser diode into the holes and switch it on. Many innocent laser diodes have died having been abused in this way. A laser diode is current hungry, it will take all it can get. If your batteries are weak your laser will be saved by the fact that it will not get much power, put a new set of batteries in and the laser will draw high current, it will heat up, which makes it try to take more current...then it dies.
Turn a MiniMag flashlight into a powerful DVD laser pointer! This 245mw laser is powerful and fits real cozy in a MiniMag! See the video at the end for the Test Results!
The Institute of Electrical and Electronics Engineers ( IEEE , read I-Triple-E ) is a professional association headquartered in New York City that is dedicated to advancing technological innovation and excellence. It has more than 400,000 members in more than 160 countries, about 51.4% of whom reside in the United States . [ 2 ] [ 3 ] [ edit ] History The IEEE is incorporated under the Not-for-Profit Corporation Law of the state of New York in the United States . [ 4 ] It was formed in 1963 by the merger of the Institute of Radio Engineers (IRE, founded 1912) and the American Institute of Electrical Engineers (AIEE, founded 1884). The major interests of the AIEE were wire communications ( telegraphy and telephony ) and light and power systems. The IRE concerned mostly radio engineering, and was formed from two smaller organizations, the Society of Wireless and Telegraph Engineers and the Wireless Institute.
