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 is intended to let the user turn off a lamp by means of a switch placed far from...
The circuit is based around LM4702 manufactured by NATIONAL semiconductors MJ11029-MJ11028 by ON...
The 5AH will trigger when the voltage across the two 0 juF capacitors reaches the breakdown...
A unique push-pull parallel circuit. It uses four MRF150 RF power FETs paralleled at relatively...
Using an RC oscillator, an up to 24-stage ripple counter O) 16777216 or 2U, and a 0.1-Hz...
The moisture detector uses two transistors and a piezoelectric transducer to sound an alarm tone...
The circuit is designed to be fitted into a small box and then fitted into your backbox (the...
This is a schematic of a cable TV signal booster amplifier circuit which can be used to amplify...
This electronic project stereo amp is based on the STK415-090-E class H audio power amplifier...
The ZN414 is a low cost, single-chip AM radio integrated circuit. Launched in 1972, the part was...
This 2 channels audio mixer is based on the 2n3904 transistors which forms 2 preamplifiers. The...
Although not a new device, the LM317 is still a high-performance regulator. Its output voltage is...
ICs that in the past were far too expensive for the hobbyist tend to be more favourably priced...
The simplest Analog to Digital Converter (ADC) can be constructed as shown in Figure 1. Input...
In the work process analysis circuit diagram, for example, and use of work in flyback converter...
1C foot VIII made a number of training device, from the trigger terminal CI. f-off positive input...
500A-6V single-phase power supply circuit Thyristor electroplating It can output DC 500A, 6V...
Circuit as shown with W7805 positive current source application integration circuit composed of...
