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 may well be the world`s only discreet logic circuit to generate truely random output. It...
This design was developed by request of a correspondent having made a sort of LED candle and...
The applet shows a simulation of Chua's circuit, plotting the voltage measured across C1 against...
Rf = 100 k preset - The slider is set about a quarter of the way round. This is used to control...
The KD2BD Pacsat Modem is a low cost, high performance 1200 bps BPSK modem designed to interface...
With the inspiration from lab 3, Digital Waveform Synthesis, I want to make a project that can...
The EUA2123 is a high efficient Class-D Audio power Amplifier for delivering up to 2G—20W into a...
The OPB350 series liquid Sensor is designed to work with 1/16 [1. 6mm] 1/8 [3. 2mm], 3/16 [4. 8...
The ISL6528 provides the power control and protection for two output voltages in high-performance...
The ISL62381, ISL62382, ISL62383, ISL62381C, ISL62382C and ISL62383C family of controllers...
Low-drain circuit operating from 1. 5-V cell uses National LM3909 flasher IC to simulate...
Ai comparator input than + mine Rl, when the output Japan level, A: The Congress lost dry -VREP...
Circuit principle is shown in FIG apparatus. When the night light irradiation on the...
