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.....

This charger will quickly and easily charge most any lead acid battery. The charger delivers full...
For SR AB763 driver replace: 25k pot, 0.1uF cap and 4k7 resistor with 100 ohm resistor to ground....
This structure is an amplifier RF, covering the range of UHF and intended for small TV...
My major project over the last few months has been the construction of a small Tesla coil, having...
The 555 on the right is wired as an alarm sound generator and the second 555 timer on the left is...
The voltage measurement is very general in electron technology at present, accuracy requirement...
The circuit detects a sudden shadow falling on the light-sensor and sounds the bleeper when this...
The circuit uses a 555 timer wired as an astable oscillator and powered by the emitter current of...
This siren alarm circuit diagram is based on a specialized IC UM3561, which is a low power CMOS...
This is a simple electronic alarm circuit that imitates the chirping of a canary. The circuit is...
Above is a schematic diagram of a type of audio oscillator known as a twin "T" phase shift...
The machine used a 12 digit display (8 LED anodes scanned by an Anode driver, and 12 `digits`...
I`ve been doing some CW contesting with my K2 and N3FJP`s Logging Software and since I now have...
14 watt equivalent light with just 1. 2 watts input. No, the light will be brighter and brighter...
Using an Atmel ATTiny2313 microcontroller and an HD44780-compatible character LCD display, along...
Circuit shown in Figure 3-86. The line utilization time relay to control two motors, one of the...
