aders Yi in the town might find this a non-electric shoe often, especially as a thyristor level training dimmer, does little wrong, if the only way to remove large capacitance iLl the (j, E on the foot of a regulator now exist ten mountain capacitor C, connected to power after charging E puncturing long, when C, song terminal voltage .C banished to a certain value by R:. lu product thyristor V1 gate discharge, VT Jf pass, string lights lit when F. AC zero crossing, VT curse off, the lights off, f, fork reed new start charging again and again, so as to form ultra-low frequency oscillation, the flash lamp Shen Xi fa 1 VII. circuit flashing frequency rate is mainly composed of R, and when asked c constant central reference, by target data string lights E drawer light 2s, put out 2s. If the infant plus fast blinking frequency can be reduced} U barrier resistance R. Kang. VT should be used to trigger a small electric current small plastic tube Li unidirectional product, such as 2N6565 and other punishment. (j, ( to request using CBIj-160V TV polypropylene capacitors. E-machi mining lamp light strings sold City, Sichuan own or the same size small bulb in series, the power package should be controlled in 10 0W less.
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.....
