    Portable Morse Code Practice Oscillator Little circuit of a Morse Code Oscillator is presented here. Excellent for learning and teaching Morse code, this code practice oscillator – ideal solution to practice sending the code and improve your speed – is a light-weight portable unit powered by one AA cell (1.5V/1.2V) and is based on the well known...
    Dew Heater Controller For Telescope Dew (condensed moisture) is one of the astronomer’s worst enemies, and all telescopes are subject to the dew problem. If no precautions are taken, it can easily destroy a perfect observing night, as it forms on mirrors and lenses, thus it is required for almost every amateur astronomer to have some kind of dew control...
    Model Railroad Controller with Presence Detector Railroads are a big part of the history. They take us back to an earlier time where once trains were the fastest way to cross a huge land. Model Railroading could take you back to those more good old times, and it is a greatest hobby. Probably,you have already noticed that this will be one of the most rewarding and relaxing...
    Model Rocket Launch Controller Model rocketry is an amusing hobby! Model rocket launcher circuit presented here is carefully designed to avoid accidental ignition, and is capable of delivering battery power to the igniter in an efficient manner. This will avoid launch failure and maximize the battery life. A model rocket launch controller is designed to do...
    Bird Bath Fountain Monitor A bird bath fountain (a small shallow pond-created with a water-filled basin- in which birds may bath and from which they may drink) can be a garden ornament, small reflecting pool, outdoor sculpture, and part of creating a vital wildlife garden. It is an attraction for many different species of birds to visit gardens,...
    RF Spy Bug Detector Circuit Here is a simple RF bug detector that will help you detect spy bugs and can operate up to 2 GHz. Below are some essential things required for this circuit: to cover a large frequency band make a sound during the detection optical and acustical indication when near the bug sensitivity not too high in order to accurately locate...
    Infrared Model Train Detector This simple and economical IR model train detector circuit is intended especially for those hobbyists who wish to add a smart sensor to detect trains on their model railway track. As can be seen in the schematic diagram, it comprises of a simple infrared transmitter and receiver wired around the good old PLL Tone Decoder...
    PCB Drill Speed Controller with 555 Described here is a simple, inexpensive and useful circuit for electronics hobbyists. The circuit is nothing but a PCB drill speed controller, which can be used to control the speed of any 12VDC small pcb drilling units. Such portable units are now widely available, and even a hobbyist can make it without too much difficulty....
    Test Human Reaction Time with the 555 IC With this simple circuit that is built with the 555 IC you can test human reaction time. You can find out how fast do you react by trying to catch a flashing LED. How does the human reaction tester works? When S1 is ON the circuit acts as a astable multivibrator and the LED is lit for about 0.1 second and is flashing every 1.5...
    Strobe Lights Project Stroboscopic effects of lights for nightclubs are realized by bringing into play old white Light Emitting Diodes (LEDs) swapping the ejection lanterns/lamps for superior effectiveness at minimal cost. This control is achievable by instantaneously changing the Light Emitting Diodes on & off at elevated volts for small...
