    Lost Model Alarm for RC Planes Here is an affordable circuit of a tiny, lightweight, and easy to handle lost model alarm (LMA) for model RC planes. A simple LMA beeps so you can listen for it while you carry out your search and rescue mission. If you have a lost model alarm fitted in your RC model you will be able to walk straight to your model and retrieve...
    High Power Ozone Generator Here is a more powerful ionisator and ozone generator than described in my version-2. It is meant for continuous operation in problem spaces such as cellars with some rot & mould. It can also be operated in normal living rooms when you are not at home. But it is too aggressive for your lungs, if used continuously in...
    Low Power Ozone Generator Generating ozone and negative ions in the air can be done by a corona discharge. For this we can use a sharp tip of negative polarity, acting against a flat metal part of positive or neutral potential. The device generates negative air ions and ozone. The ozone acts against rot and mould, and can refresh the unhealthy air of...
    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...
