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.....

When the start switch is pushed, the output of the charger goes to 14.5 V. As the batttery...
With this circuit you will be able to monitor the quality of the mains. There are 4 distinct...
The circuit switches the current to an electrical heater on and off to maintain the temperature...
A bar column of LEDs is arranged so that as the audio signal level increases, more LEDs in the...
The reference current is fed from the supply voltage via Rl, to the inverting terminal, and the...
Here the simple audio mic pre amplifier circuit based on single IC LM358. The circuit is very...
A bike with 35 watt HS1 bulb and I want to upgrade brightness of headlight so I decided to put H4...
This simple circuit allows a 12V battery pack to be charged via a bike generator. The generator...
The High Power Amplifier has great advantages are 5000W ultra-light, high-power audio amplifier,...
This article explains how to build the second improved version of the HDR-Jack. In contrast to...
A 4-bit adder which adds two four bit binary numbers with a Carry in line. The diagram above show...
Now we will build a very simple photoresistor circuit to make a photoresistor do what it does:...
741 opamp is connected as audio oscillator with Radio Shack 276-677 photocells in feedback...
Here is the single- 813 crystal oscillator transmitter, designed by RCA and exhibited in their...
