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 camera rotator circuit uses a 2716 EPROM to store a table of logic values that control the...
This is not a sophisticated automatic keyer but it is lot QRP to build and to have fun operating...
The 555 acts as the tone generator configured in the astable mode. Its pin 3. square-wave output...
In this circuit, audio fed to the control channel is amplified and rectified by Dl and D2. This...
To provide rapid motor speed changes and motor direction reversal, four outputs drive a MOSFET...
This is an article written by a one of my readers, Yash Tambi, Core Committee Member, roboVITics....
This Design Idea came about as a result of my not having access to those wonderful new ICs that...
You might find yourself needing a low power H bridge for driving a motor like I once did. The 555...
A simple thermometer built with operational amplifiers and a normal or protective diode such as...
When controlling motors with a microcontroller (like shown), the snubber is really pretty...
This is a "quick-and-dirty" page that I set up to describe the T1-rate modem that I designed...
This is a very easy circuit that every one could make and have fun. This project popped out of...
By two NAND gates Di, Dz and resistor Rz, capacitors Cl etc. RC self-excited multivibrator...
