Mini 3 transistor amplifier is a simple amplifier with 50mW power drawn by 3 transitor. The series of three mini-amplifier transistors can be used for loud speaker 8 ohm load. Source voltage required to activate the mini-amplifier can be drawn from the batteries 9V.Rangkaian 3 transistor amplifier is often used in simple portabe audio devices such as radios or small tape recorder. Mini-transistor amplifier circuit 3 is quite simple as shown in the figure below. Mini-transistor amplifier circuit 3 includes type of amplifier OTL (Output Transformer Less). Mini-transistor amplifier circuit 3 is used for output coupling capacitors. Amplifier circuit is simple and suitable when used for audio amplifier experiment.

Linear scale-Small size 40 to 208 beats per minute Mini Metronome Circuit diagram:   Notes: Q1 & Q2 provide linear frequency operation of IC1 following P1 resistance variation. Q3 was added in order to obtain a louder click, similar to clockwork metronomes. 12V micro battery was used to obtain more output power and more compactness. Rotate P1 fully towards R2, then set R1 to obtain 40 beats per minute (compare with another metronome). Rotate P1 fully towards R3, then set R4 to obtain 208 beats per minute. Finally mark the entire scale with the usual metronome steps as following: 40 - 42 - 44 - 46 - 48 - 50 - 52 - 54 - 58 - 60 - 63 - 66 - 69 - 72 - 76 - 80 - 84 - 88 - 92 - 96 - 100 - 104 - 108 - 112 - 116 - 120 - 126 - 132 - 138 - 144 - 152 - 160 - 168 - 176 - 184 - 192 - 200 - 208.

Here I present the stabilizer circuit of the IC 78XX and 79XX commonly used for voltage stabilization with a mini PCB design , and practical. In the picture above is looking from top the PCB, with a width of 2 cm and 5 cm height. For input voltage can be directly through the AC because i've put it four rectifier diodes are then forwarded to the Elco and IC , that has a stable output in accordance with IC series. What if the IC series 7805 and 7905 , the output voltage of 5 Volts. If the series IC 7812 and 7912 then the output voltage of 12 volts , and so on. See circuit schematic below : Part List : D1,D2,D3,D4 = 1N4007 C1,C2             = 1000 uF/50V C3,C4             = 470 uF/50V IC1                 = 78xx series IC2            ...

Mini High-Voltage Generator Circuit diagram. Here’s a project that could be useful this summer on the beach, to stop anyone touching your things left on your beach towel while you’ve gone swimming; you might equally well use it at the office or workshop when you go back to work. In a very small space, and powered by simple primary cells or rechargeable batteries, the proposed circuit generates a low-energy, high voltage of the order of around 200 to 400 V, harmless to humans, of course, but still able to give a quite nasty ‘poke’ to anyone who touches it.  Quite apart from this practical aspect, this project will also prove instructional for younger hobbyists, enabling them to discover a circuit that all the ‘oldies’ who’ve worked in radio, and having enjoyed valve technology in particular, are bound to be familiar with. As the circuit diagram shows, the project is extremely simple, as it contains only a single active element, and then it’s only a fairly ordinary transistor. As sho...

This small amplifier was intended to be used in conjunction with an electric guitar to do some low power monitoring, mainly for practice, either via an incorporated small loudspeaker or headphones. The complete circuit, loudspeaker, batteries, input and output jacks can be encased in a small box having the dimensions of a packet of cigarettes, or it could be fitted also into a real packet of cigarettes like some ready-made units available on the market. This design can be used in three different ways: Mini Portable Guitar Amplifier Max output power:  1.5W @ 9V supply - 8 Ohm load; 60mW @ 3V supply - 8 Ohm load Frequency response:  Flat from 20Hz to 20kHz Total harmonic distortion @ 100mW output:  0.2% Max input voltage @ 3V supply:  8mV RMS Minimum input voltage for Fuzz-box operation:  18mV RMS @ 3V supply Current consumption @ 400mW and 9V supply:  200mA Current consumption @ 250mW and 9V supply:  150mA Current consumption @ 60mW and 3V supply: ...
