Reading time: 3 minute The vintage DIY electronic kit presented is a signal of the presence for dangerous places or difficult to observe at night. Because the signaling control starts at dusk and stops at dawn, this vintage DIY electronic kit falls into the realm of small automations.
Reading time: 3 minute Remote control is a common procedure in many applications. Through audible signals or mechanical shocks, this vintage DIY electronic kit can put into operation a lamp, a motor, an electromechanical toy, etc. The scheme contains two amplification stages, a flip-flop and a final floor.
Reading time: 3 minute Obtaining intermittent light signals with the help of electronic assemblies is a process found in many applications. This vintage DIY electronic kit, realizes these commands through an electronic circuit consisting of 2 transistors, a capacitor, 4 resistors and 4 lamps (bulbs).
Reading time: 2 minute Remote control is a common procedure in many applications. Through audible signals, or mechanical shocks, this vintage DIY electronic kit can operate various electrical or electronic circuits.
Reading time: 3 minute The number of possible applications with such a scheme is unlimited. We mention only a few of them: operating the garage doors, lighting some light bulbs depending on the daylight, ordering some toys, etc.
Reading time: 2 minute This vintage DIY electronic kit features a microphone preamplifier. The assembly ensures a uniform amplification in the 30Hz - 30kHz band of a signal received from a microphone. The scheme includes 2 BC 172B transistors, resistors and capacitors.
Reading time: 2 minute The montage is addressed to those who are willing to learn or practice the Morse code. The vintage DIY electronic kit is an audio frequency generator consisting of two transistors, a resistor and a capacitor.
Reading time: 2 minute The DIY electronic kit presented in this article, electronically generates an electrical signal which, transformed into sound by a speaker, resembles that generated by classic sirens. The diagram includes two stable circuits, a training circuit and a power amplifier.
Reading time: 3 minute This DIY electronic kit synthesizes an electrical signal which, transformed into an acoustic signal by means of a loudspeaker, will have characteristics similar to dog barking, imitating it. The diagram includes three stable cells and a power amplifier.
Reading time: <1 minut The project is based on the LM555 integrated circuit. For this application IC1 works in monostable mode. The mounting input is connected to terminal 2 of the LM555 integrated circuit. Here we have the "touch sensor" designed from a wire, or from a "fork" type route. Basically, when we touch the wire, or the "fork" route, the K1 relay is activated.
