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.....

Micro-Cap 9 is an integrated schematic editor and mixed analog/digital simulator that provides an...
This box is a set of nine relaxation oscillators. It blinks random patterns and looks cool. When...
Your 5x7 display is my favourite toy; the tunes and graphics in the elevator display always...
The meter will indicate the frequency from a power generator. Incoming sine waves are converted...
When the time delay expires, SCRl conducts and removes the gate signal from SCR2, which stops the...
Overcome a major drawback of the SPI bus. But to explain this, allow me to go on a little detour...
The PIC/Generation 1 electronics do not have any form of current limitting. They rely on the...
The 30 watt amplifier circuit shown below provides an appropriate power boost with an input of 4...
Circuit To relieve you of any concern related to high frequency, I used a module ready, in case a...
This is a 100 watt basic power amp that was designed to be (relatively) easy to build at a...
This circuit has been very useful in filling a header tank for a reticulated water supply on a...
As shown in FIG inverted to adopt IC1MAX868 and CMPSH-3S consisting of four times the pressure...
