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.....

All ATL-3 loop windings are centre tapped and balanced w.r.t. their amplifier/receiver chassis...
This circuit is designed primarily for the situation where a hijacker forces the driver from the...
In spite of the improvement of communication link and despite all progress in advanced...
Indicator provides an accurate comparison of two voltages by indicating their degree of balance...
This heat detector alarm electronic project is designed using the UM3561 sound generator circuit...
This siren alarm circuit diagram is based on a specialized IC UM3561, which is a low power CMOS...
This circuit is intended to signal, through a flashing LED, the exceeding of a fixed threshold in...
This is a very simple transistor tester circuit the circuit can be used to test NPN and PNP...
This simple circuit can be used as an aid for sensing the distance between the rear bumper of the...
When the potentiometer is at the up position, the capacitor will charge quickly through both 1k...
Connect the components. Take note of the connections for the transistor. Connect the 22 ohm load...
1999 Buick Regal. Instrument panel lights have failed. Examined fuses related and even those not...
This page describes a color clock that displays the time using two RGB LEDs, one for hours and...
220V AC power via VD1 ~ VD4 bridge rectifier and voltage regulator circuit through R1, R2, VD5 cl...
As shown in FIG To eliminate hum instrument amplifier circuit. FIG amplifier stage A1, A2...
Circuit Description: Under inject mode, the calibration circuit provided in the audio range...
