semi-conductor‚ the importance of which will be explained later. Once power reaches the microchip‚ it distributes it to different portions of the mouse including two contact switches‚ a scrolling wheel‚ the switch on the wheel‚ and a light emitting diode (LED). Before reaching any of these portions of the mouse‚ however‚ the current must flow through a series of mica capacitors‚ electrolytic capacitors‚ and resistors. In this mouse‚ five capacitors (two mica‚ three electrolytic) and one resistor

DICE . TO CONSTRUCT AN ELECTRONIC DICE USING LEDS . BACKGROUND: LED’s History The first known report of a light-emitting solid-state diode was made in 1907 by the British experimenter H. J. Round. However‚ no practical use was made of the discovery for several decades. Independently‚ Oleg Vladimirovich Losev published "Luminous carborundum [[silicon carbide]] detector and detection with

BRIEF DESCRIPTION OF DIWALI LIGHTS The Basic Circuit [pic] FIGURE 1 As you can see in the above diagram that IC LM4017 will give 10 different O/P’s. Now here I have used this circuit for a 5 Channel Sequencer (The word sequencer seems very tough but the circuit is as simple as you can think). Looking at the Data Sheet of IC LM4017 we observe that we do not need any extra components to drive this IC (and that is what makes our CKT very compact). [pic] Now build 11 circuits as

Code: 11461 21 June 2008 By Ceng Chun-chou Overview Encouraged by a good performance of organic light-emitting diode (OLED)‚ a large number of Taiwan firms have aggressively developed OLED products in recent years. But a bottleneck in technology has led to no major breakthrough in capacity‚ resulting in firms’ long-term losses and compelling some to stop research and

chapter 1 intaoduction “Driving to save lives‚ time‚ and money in spite of the conditions around you and the actions of others.”- This is the slogan for Defensive Driving. Vehicle accidents are most common if the driving is inadequate. These happen on most factors if the driver is drowsy or if he is alcoholic. Driver drowsiness is recognized as an important factor in the vehicle accidents. It was demonstrated that driving performance deteriorates with increased drowsiness with resulting crashes

CIRCUIT IDEAS FUEL RESERVE INDICATOR FOR VEHICLES D. MOHAN KUMAR ere is a simple circuit for monitoring the fuel level in vehicles. It gives an audiovisual indication when the fuel level drops alarmingly below the reserve level‚ helping you to avoid running out of petrol on the way. Nowadays vehicles come with a dash-mounted fuel gauge meter that indicates the fuel levels on an analogue display. The ‘reserve’ level is indicated by a red marking in some vehicles‚ but the needle movement through
