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.....

The oscillator is a standard UHF design which delivers about 10 mW at 1.2 GHz. R1 and R2 bias the...
We propose a comprehensive design procedure to design Field-programmable/Reconfigurable Analog...
When the reverse voltage is applied that is say 10V to Source and the drain is grounded. So now...
This Dummy Alarm project makes an LED flash briefly once every 5 seconds to imitate the indicator...
A line follower robot, or a LFR in short, is a simple autonomous robot that optically tracks a...
By sufficiently lowering output impedence of a circuit and supplying enough current to drive...
This is a project I`ve done on behalf of a person on an internet forum. The requested operation...
This light sensor circuit that is photos sensor is the gap between light and electronics. This...
It`s a slight redesign of a board I did before last year`s AVC. What`s it for Not telling yet. :)...
The electronic circuit is a TV modulator that is really no more than a transmitter. It is a very...
The SM5021 series are crystal Oscillator module ICs fabricated in NPCs Molybdenum-gate CMOS, that...
The circuit uses a total of six, 12 volt lead acid batteries to power the load. 3 batteries are...
CXA1019 Japan SONY companys high-performance, high sensitivity FM AM radio special manifold....
Closed lights switch S, 220V AC via RP1, RP2 R and the capacitor C2 is charged when the voltage...
