the self-excited multivibrator, the buffer amplifier and high voltage generating circuit, shown in Figure 24-2. Self-excited multivibrator transistors VT1, VT2, capacitors c1, c2, and a resistor R. -R. And other components. Buffer amplifier circuit by the emitter follower amplifier tubes VT3, wind bias resistor, R. And a coupling capacitor C, C4 composition. High voltage generation circuit by the potentiometer RP, resistor Rs, amplified output tube VT4, auto-type step-up transformer T and output jacks acne XS components. (2) works self-excited multivibrator generates a frequency of the oscillation signal of about 500Hz, the VT3, VT4 amplification and transformer T boost after treatment, from the socket at the output is greater than xS iocf , 1 high-voltage pulse voltage. The pulse voltage by two external electrode sheet was added to cough patient days sudden hole (riding his head, in the chest on the edge of the middle notch accounting depression) and too vertebral points (commission conical cap or sitting down in the first 7 cervical spine), adjust the positioner RI resistance, can change the output voltage of the high-voltage pulse amplitude, to adjust the intensity of the electric pulse.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
