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 microcontroller fascinated me a lot because I wanted to see what we can do with an 8-pin...
A 100 second delayed turn ON relay RL1 switch, if plug power +12V in circuit. In Fig.2 see a two...
This tester provides an audible indication of the logic level of the signal presented to its...
In this circuit, data at input C is amplified by IC2 and then fed to modulator IC1. IC1 g
Ql, Q2, and the associated circuitry form a modified astable multivibrator in which the loop...
This circuit is useful if you need a low-energy flashing alarm. The 200 to 400-dc supply should...
Sometimes you need a low voltage power supply of very high currents (hundreds of amperes) -...
When the circuit is first powered up, neither transistor will be switched on. However, this means...
By using light and sound to induce these brain states we are able to gain greater control and...
One problem this causes is that the lovely USB port that I have been using to communicate with...
This circuit measures the distance covered during a walk. Hardware is located in a small box...
This oscilloscope clock project uses a PIC 16F876 and a DAC to generate X and Y signals to draw a...
To be independent of the local radio stations for testing VHF receivers, you need a...
Higher bandwidth connections are made by grouping 4 or 12 pairs together, for up to 3 GB/s...
