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.....

A simple test circuit to fault find audio and radio equipment. Can be used to inject a square...
When the upper or lower limit is exceeded, the LED lights up. Positive feedback to one of the...
The circuit consist of 10 k and 470 k resistors. Also one potentiometer resistor and led was...
This project demonstrates a number of aspects of the PIC16F687 microcontroller, like: ultra low...
74HCU04 is a chip that was made for this purpose, HCT may not work for such a circuit. C1 and C2...
IC bus line explains conduct and transmits the bus line as one kind, it uses and is wired little,...
This is the first oscillator I ever built. I remember looking at books and magazines, schematics...
This is a simple 2N2222 transistor based radio FM transmitter circuit within the FCC (Federal...
Here is a simple circuit that will produce a musical horn when ever your car is in reverse gear....
Using two gates from a CMOS 4011 NAND chip, a simple Squarewave oscillator can br made....
If an oscillator of a particular frequency and mark to space ratio is required, (see Fig. 4. 4....
This experiment is more of an introduction to the 4511 decoder/display driver IC than it is a...
The metal detector circuit consists of the fixed frequency oscillator, mixer, detector, detection...
The figure shows the schematic of the circuit. A number of unique features give this design its...
If you switch gears over 5k during a solar eclipse you`ll have to have your nut bearings...
Evolution FM transmitter with 2n2218 with audio amplification step using LM741 op amp with audio...
T-40-16 and 555 ultrasonic transmitter circuit configuration as shown in a, the circuit consists...
