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 "ON/OFF" button is pressed once, the equipment goes on and stays on. It goes off when...
A Class A // Class AB amplifier rated 100 Watts when driving a 4 ohm loudspeaker. This circuit...
This transmitter needs heatsink at 2N2219. With the C4 we regulate the frequency. With their C7,...
This is an easy to build, but nevertheless very accurate and useful digital voltmeter. It has...
Push-pull outputs are used in this transformer-coupled dc-dc regulating converter. Note that the...
Because the power controller is powered from the vehicle`s accessory switch, the load can...
Micro PSU to power a breadboard with 5 volts. Connect to 9V battery, 12V or any other DC...
Until Willow Garage was acquired, I was working there as a Web Robotics Engineer. Really, it`s...
The Resistive Sensor Head (A2053) is a Long-Wire Data Acquisition ( LWDAQ ) Device that measures...
After testing the motors I found current draw as high as 1. 3Amps. So I stuck 2 of the SN754410...
Many people experienced sleeping well in natural surroundings, into a tent or a wooden hut. This...
This project implements a half-duplex, master/slave communications protocol based on RS-485 bus...
Build a device to determine the depth of the flocculent layer in a lake. The flocculent layer is...
The LTC3722-1/LTC3722-2 phase-shift PWM controllers provide all of the control and protection...
A common LED driver requirements are: The LED string voltage and the input voltage is very wide...
As shown for the ISO103 ripple reduction circuit. Circuit at the output plus an RC high-pass...
As shown is 555 more cars with alarm circuit, mainly consists of a 555 and a quad 2-input NAND...
