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 Project presented here waters your plants regularly when you are out for vocation. The...
This 6V to 12V converter circuit is made with an IC from SGS with several additional components....
In this circuit. a negative output voltage de-de converter generates a -5 V output at pin A. In...
Here is the circuit diagram of a simple 24W mono amplifier using IC TDA1516. The TDA1516 is an...
The schematic diagram come from circuit: Adjustable High Voltage Power Supply 0 to 1000V power...
I accept acclimated a brace of BC548 transistors in this circuit. Although not carefully RF...
Here we describe a simple process to `put a voice on a sunbeam` and transmit it over a distance....
The basic circuit described in this document is capable of generating up to 30 kilovolts or more...
Interfacing with a HD44780 compatible display using some DIP switches and a few other components....
Another super-simple circuit. You could use this circuit to drive a low power speaker from a...
Current sensing is as it says - sensing the amount of current in use by a particular circuit or...
This circuit uses a synthesized sound chip from Holtek, the HT-2811. This reproduces the sound of...
Amplifier A1 by the voltage across the sense resistor sensors to monitor the load current ILOAD....
Electronic bass equalizer type of two quad op amp circuit, you can use TL084 high-speed...
