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 circuit employs a 100 ohm isolation resistor which enables the amplifier to drive capacitive...
Precise, adjustable control of beats per minute from a largo of 18 to a frenzied, high presto of...
If you choose to make your own moisture sensor,; this foil pattern should come in handy. A...
One of the simplest method of metal detecting is by beat frequency oscillator. Basically, the...
We know, the maximum coverage of RSR232 serial port Transport Protocol is 10M, and the wire...
When the voltage on the non-inverting input of each comparator exceeds the voltage at its...
Our project demo is also successfully finished and the only thing left to do for this project is...
This is a modified version of the first SSTC I built, the Kaizer SSTC I. It uses the same...
This circuit is describes about sensing air flow using microcontroller PIC16C781. In this circuit...
A dual channel audio preamplifier as an appropriate preamplifier for the high quality Audio...
The G‚result of the lcd is not correct the thermometer does not show the room temperature but...
This circuit will emit an intermittent beep (or will flash a LED) when the water contained into a...
To describe the performance or work of electronic schematic of Light Detector Robot as like in...
