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.....

The signal from a synchro receiver or a variable resistive cam follower (potentiometer) is...
The circuit has a typical voltage gain of 84 dB and a typical AGC range of 80 dB. It gives very...
This circuit reads and stores voltages, tbus freezing the meter reading even after tbe probes...
Using a pickup coil to drive an amplifier (IC3A-B-C-D), this meter circuit can be directly...
Transistorised Astable Multivibrator is a cross coupled transistor network capable of producing...
All you have to do is insert the pieces so that things that should connect are on the same lane....
Explore power amplifier integrated circuit from National Semiconductor LM4780. What`s so special...
Conventionally a MOSFET with a voltage rating of 1500V or with a Half-Bridge connection using two...
The line-in pin is clearly visible in the pinout of iPod connector shown on the iPod wiki. From...
The medical ultrasonic atomizer circuit is composed of power supply circuit, atomization amount...
The one-arm bandit circuit is made up of three clock circuits and three counter/readout circuits....
One can transform an ordinary binary counter, such as a 7493, into an up/down counter with mode...
This tutorial shows how you can build a small relay interface board so that you can use the U4x1...
I`ve managed to complete the first phase of my motion-controlled photography rig: setting up a...
