Here the short wave AM Transmitter circuit design diagram. The circuit is quite simple and easy to build since it applies only a few electronic components. The primary feature of this transmitter is that it really is absolutely free from the LC (inductor, capacitor) tuned circuit and runs using a fixed frequency of 12 MHz… Read More »
Automatic Switching-on Emergency Light The schematic diagram shown right here is the automatic switching-on emergency light circuit which is controlled using IC. The most important capabilities of this circuit are: automatic switching-on of the light on main power failure and battery charger with overcharge protection. When mains electrical power is absent, relay RL2 is in… Read More »
Powered with solar panel, the circuit will give you 5V pure regulated DC voltage. This solar cell power supply circuit is made up of an oscillator transistor as well as a regulator transistor. The solar panel charges the battery when sunlight is bright enough to generate a voltage above 1.9v. A diode is necessary between… Read More »

Amplifier Parts list: P1 22K = Log.Potentiometer P2 = 100K Log.Potentiometer R1 = 820R R2, R4, R8 = 4K7 R3 = 500R Trimpot… Read More »
This is the positive voltage regulator circuit with PNP Boost transistor: The IC8211 presents the voltage reference and regulator amplifier, while Q1 will be the series pass transistor. R1 defines the output current of the IC8211, while C1 and C2 present loop stability and as well act to suppress feedthrough of input transients to the… Read More »

This document contains schematic diagram of Orange 125MK3 including the guitar preamp section, feedback and power amplifier section. Preview:
This is the scheme diagram of automatic 9V battery charger circuit, the parts list provided below the schematic image. The circuit was designed by Jan Hamer, translated by Tony Van Roon dan republished in this circuit diagram site. The circuit details are based on european standards: 120E, 150E, etc. The ‘E’ just stands for Ohms… Read More »
This is the circuit diagram of Fuzz Face mods, guitar effect pedal. This is a modified diagram and simpler than the original Fuzz Face diagram. You will find apparently two identical designs of the fuzz face. In one Q1 and Q2 had been PNP germanium AC128 or NKT275 types, in the other they had been… Read More »
