Reading time: 4 minute The neon lamp powered by this installation allows lighting in the absence of the electrical network (for example in camping conditions) or in case of damage to this network. The electronic DIY kit presented aims to familiarize the amateur electronics engineer with the construction and operation of a simple converter with transformer.
Reading time: 4 minute This DIY electronic kit contains all the components needed to build a 15W audio frequency amplifier. Its performance, the relatively affordable price of the components, the ease of execution, make it accessible to any electronics enthusiast passionate about the audio field.
Reading time: 4 minute The assembly can be used to amplify the signals obtained from a pickup (vinyl player) with magnetic dose. The vintage DIY electronic kit presented is intended to familiarize the electronics technician with the performance and construction of preamplifiers with the corrected frequency characteristic.
Reading time: 3 minute The electronic DIY kit presented is intended to familiarize you with the performance and construction of preamplifiers with low input impedances. The realized assembly can be used as an amplifier for measuring devices, in automations, picup with ceramic dose, etc.
Reading time: 5 minute The vintage DIY electronic kit presented extends the service life of nickel cadmium (NiCd) watch batteries, whose voltage did not fall below 70% of the nominal voltage value of 1.5V, by their periodic regeneration, every few months.
Reading time: 4 minute This vintage DIY electronic kit is a time relay, with a time delay of at least 165 seconds, indicated (at that time) to signal the 3 minutes of a telephone call being exceeded. This 3-minute delay was used because at that time (1988), if this time was exceeded, additional costs were imposed. Of course, the assembly has various other applications in electronics and not only, being relatively easy to build.
Reading time: 4 minute This vintage DIY electronic kit was launched on the market in 1981 and was an assembly loved by amateur electronics because of its simplicity and enough power for an apartment. The 2N3055 power transistors can be easily purchased as well as the other components. The article also specifies the values of recent equivalent components.
Reading time: 5 minute This vintage DIY electronic kit is a light organ with 3 projectors (bulbs), with the light effects rate adjustable by a rotary knob. The bulbs will light up depending on the intensity of the input signal and its frequency, producing special lighting effects.
Reading time: 3 minute The assembly is easy to do, being practically an interactive electronic kit for children. The scheme of this vintage DIY electronic kit consists of two stable tilting circuits (CBA).
Reading time: 3 minute An audio frequency generator is an electronic assembly that must not be missing from the workshop or laboratory of any amateur electronics technician. Such a generator can be used in the most diverse electronic applications: debugging, generation of onomatopoeias, checking of audio frequency amplifiers, electronic sirens, etc.
