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.....

I like to see lights move to music. This project will indicate the volume level of the audio...
The above pictured schematic diagram is just a standard constant current model with a added...
This converter can accommodate wide inputvoltage swings, such as the 8 to 15-V swing typical of...
This switching circuit acts like a bank of interlocked mechanical switches; pushing one of the...
In this post I will attempt to describe the steps I took to build the arduino based thermostat...
This transmitter has a size about that of a large coat button. The transmitter accepts direct...
The normal assumption is that the phase shift sections are independent of each other. Then using...
Need to amplify the output of the iPod`s headphone jack would not be enough to provide the chip...
This Digital Alarm Speedometer Circuit. It allows us to appraise the acceleration of any article...
The circuit shown here works from 24V DC and can flash two 24V bulbs alternatively. The circuit...
Each components of the circuit is shown in a simple block form with a corresponding label for...
Measurement microphones differ from recording microphones and sound meters-they have a flat...
The one-arm bandit circuit is made up of three clock circuits and three counter/readout circuits....
Taking the wiring going to the external amp, in the 15 pin connector you will want pins 8 and 9....
1500A-7V-phase thyristor power regulator circuit a plating It consists of the main circuit,...
Circuit shown in Figure 3-148. The circuit eliminates the need for step-down transformer, using...
