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 circuit can be used to remotely monitor a loudspeaker, alarm, or audio source for presence...
The transmitter is a very simple crystal oscillator. The heart of the circuit is the tuned...
The entire circuit is powered from a very simple regulated +-15V power supply, that is able to...
Shown here arc several possible interface circuits that can be used with the remote-control...
Even though today`s electrical appliances are increasingly often self-powered, especially the...
When the phototransistor is stroken by IR light it conducts and the voltage between the 1Mohm...
I n this circuit, the alarm will be switched on under the following four different conditions: 1....
Metal detectors are usually very complicated and it may be consist of very costly components and...
We mounted one of them on a wooden sigar box and connected the anode via a large series...
This metal detector schematic circuit is based on a transistor radio as an detector .This metal...
A very simple low cost water level indicator circuit can be designed using this schematic...
Although you don`t find SCR and Triac in all electronic equipment, this does not mean that both...
The idea for this circuit came when the author had problems with the wireless speedometer on his...
Circuit core device is a dimmer SM7232 specific integrated circuits, which leads to the foot of...
300B is a high reliability, excellent characteristics of the power amplifier transistor 6 in the...
A constant current source of the differential amplifier circuit (2) having a constant current...
As shown for the basic connection circuit INA326/327 signals and power. Selection of the highest...
This transmitter of 255W is depended on the coils we put at it to work in both the middle and the...
