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.....

Here is a handy gadget for test- ing of infrared (IR) based re- mote control transmitters used...
The GLMDA is designed to detect the motion of a human or animal both in daylight and at night...
Cl, C2, and C3 are miniature ceramic or plastic trimmers- Tl (main winding) is 0.34 µ,. Use of...
Wien bridge sine-wave oscillator using two RCA CA3140 op amps cover» 30 Hz to 100 kHz with less...
In many situations you need some kind of human interface to your microcontroller project. In this...
Using a mobile phone while driving is dangerous. It is also against the law. However, you can use...
Personal Radar System using PIC MIcrocontroller PIC18f452 is a microcontroller hobby project. The...
If you want a 1MHz square wave, I would suggest using a higher frequency crystal and dividing it...
This is the built servo amplifier and circuit diagram. This is a simple and ordinary op-amp...
A pH electrode measures hydrogen ion (H+) activity and produces an electrical potential or...
When the switch is pressed C3 charges up through R4 with a time constant of 0. 47 seconds and...
Car Inverter (Power Converter, Power Inverter) is a way to convert the DC DC12V and AC220V AC...
With many audio systems consisting of separate units, you`ll oftennd that due to economic...
The Quick and Easy Wireless circuit is not terribly difficult however it will take some double...
