Intelligent Water Pump Controller with Water-level Display - Most of the circuits for multi-level indication/control of water in tanks employ a bunch of wires running between the circuit and the overhead tank, which accounts for almost half the cost of the entire project. Here is an intelligent scanned water-level indicator-cum-pump controller circuit that utilises just four wires to the overhead tank to indicate nine different levels.
Interior light extender - All modern cars are fitted with door-switch operated courtesy lights. Useful devices, but not quite as useful as they might be because they are so arranged that the light is extinguished as soon as you close the doorjust when you need light to find the ignition switch. do up your seat belt etc. How much better if the internal light stayed on for a few seconds after the door is closed. This little project does just that. It provides a four-second delay (approx) after which the interior light slowly dimsbeing finally extinguished after 10 or 12 seconds. The unit is very simple to construct and once tested and properly insulated it may be wired across one of the car door switches. In operation, after a short delay the lights will gradually dim until they are completely extinguished. There is no battery drain in the off-state as the unit only operates during the delay period after the door is closed.__ CdS Electronic

IR Proximity Sensor - It is the same principle in ALL Infra-Red proximity sensors. The basic idea is to send infra red light through IR-LEDs, which is then reflected by any object in front of the sensor. Then all you have to do is to pick-up the reflected IR light. For detecting the reflected IR light, we are going to use a very original technique: we are going to use another IR-LED, to detect the IR light that was emitted from another led of the exact same type!This is an electrical property of Light Emitting Diodes (LEDs) which is the fact that a led Produce a voltage difference across its leads when it is subjected to light. As if it was a photo-cell, but with much lower output current.
