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 complete high quality, low noise 5-BAND GRAPHIC EQUALIZER circuit is based around Monolithic...
This converter allows reception of signals below 500 kHz on a 3.5 ? 4 MHz HF receiver. It should...
The figures below illustrate using opamps as active 2nd order filters. Three 2nd order filters...
When the driver depresses pushbutton switch S1, timing capacitor C1 charges to 12 V and turns on...
This recorder can be connected to the telephone lines just about any place, and no external power...
The input consists of two comparators that operate with different reference voltages supplied by...
Build an oscillator that will satisfy a few requirements. The main requirement is to have exactly...
The tuner is programmable via I ²C-Bus and provides a FBAS signal at its output. There is also...
The handheld mini light beam receiver. On the left is a small solar cell, you can make out the...
National Instruments Multisim now has microcontroller unit co-simulation capabilities, allowing...
LCD segment number growth increases the pin number of package in LCD driver. The LCD driver IC...
This Hartley oscillator was built on the remains of a single tube Hartley using a single 45. The...
This project is a simple 12V to 220V modified sine-wave inverter using 555 timer IC and CD4017...
The DZ-2 was built by RCA, Camden NJ, for the U. S. Navy for use in naval aircraft as a Radio...
