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 is a circuit for a game of the shooting gallery variety. IC2a and b form an astable...
This simple stereo amplifier uses a National LM3871C. The pin numbers in parentheses are for...
When the reverse voltage is applied that is say 10V to Source and the drain is grounded. So now...
By using light and sound to induce these brain states we are able to gain greater control and...
This circuit is conventional Pierce type oscillator that uses a JFET. The circuit uses...
This is example project in which the 8051 is Producing PWM outputs for seperate two channels, The...
When it is necessary to send a digital signal between two electrically isolated circuits you...
Here is a simple PWM dc to ac voltage inverter circuit based on IC SG 3524. The SG3524 IC chips...
This circuit is intended to indicate the power output level of any audio amplifier. It is simple,...
The clock shows time in 5 minute intervals. The hour and minute can be set. There is no alarm or...
Used in high-quality stereo cassette deck operating from AC line or battery. Meter rectifier...
As shown in Figure 555 constituting the DC capacitor tester. The tester from the pulse...
Chen is in the OP put too amplifying circuit, so that the comb over current feedback loop with...
FIG. 3 a king in Figure 5, the circuit OP37 composed of multi-preamplifier o OP37 is a ratio of...
