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 makes a nice lamp that consumes little power, runs cool, and has an incredibly long...
An NEC602 is used as a mixer with a zero IF frequency output, U2 acts as an audio amplifier....
This allows a TSCM specialist the ability to "blink" a Spectronics bugging device on for a second...
This 3V to 24 volt variable-regulated power supply can be adjusted from 3 to 25 volts and is...
When connection to PC speaker is plugged in and Telephone connection(bottom-left) is plugged in,...
The main system is the user interface and control system. The phone line was chosen as the method...
The following article discusses a few very simple intrusion detector circuits, or simply burglar...
Here is the schematic of a simple DIY solar cell phone or USB charger circuit. This solar USB...
Transformers made for powering large neon signs are inexpensive and very reliable. Most commonly,...
Magnetic (or electromagnetic) water descaler devices have been showing up on the shelves of Home...
I have found the schematic diagram on Metal Detector For this class it does not have to be...
The sound produced imitates the rise and fall of an American police siren. When first switched on...
Computes the gain and the input and output resistances and automatically sends the results to the...
Transistor radio shows common OTL power amplifier circuit, VT5 bias resistor driver stage. VT6...
It uses reed KR V control thyristor conduction, with 555 integrated circuit path consisting...
