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 schematic is very simple and includes, in addition to Nutchip, with its three driving...
The display shows each increment. By using mode 2, external debouncing of the gate switch is...
The following applications circuits are intended to illustrate the following points: A 2-KO...
This simple receiver AF amplifier can supply several hundred milliwatts to an 8- speaker. The...
A BA1404 IC is used to generate a complete FM MPX signal. The chip contains all of the necessary...
Even though today`s electrical appliances are increasingly often self-powered, especially the...
Controlling devices using switches are common. From a few decades controlling devices using...
This one is actually a bit simpler to explain: the op-amp is set up with 25. 50x amplification,...
There are many kinds of AVR programmers in market, most of these use the parallel port, a serial...
The OP07 is in a non inverting amplifier so as not load the mV of thermocouple, the zeners are to...
An 5 pole elliptic low pass filter (impedance: 50Ohm, -6dB cut off frequency 33MHz) connects the...
The main part of this doorbell circuit are two NE555 timer ICs. When some one presses switch S1...
A simple telephone transmitter circuit that is ideal for transmitting the telephone conversation...
The EM4294 is an analogue front end for high secure 13. 56MHz RFID reader systems. The reader...
A pre-requisite for this article is that you have the GCC AVR programming environment installed...
Circuit AD1865 is considered like best 18bit stereo audio DAC ever. I already built another DAC,...
The CM-CU21 is a high quality, portable Commentator Unit. Its sturdy construction and flexibility...
AR-300 DC arc welding machine circuit Rotary DC arc welding machine has AX, AX1, AX3 and AR...
