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 following circuit are provded here to give your idea how the overvoltage protecton circuits...
The TDA2616 is a hi-fi stereo amplifier designed for mains fed applications, such as stereo radio...
This circuit uses a tachometer to generate a feedback signal which is compared to a reference...
The supply 6-66 can be used for supply output voltages from 1 to 35 V. The line transformer...
This low-power converter will supply about 100 mW of dc to a load and it is useful to isolate or...
This project is based on ISD2560P IC which allows you to record 60 seconds voice and then...
Until Willow Garage was acquired, I was working there as a Web Robotics Engineer. Really, it`s...
In this part of the inquiry in a series of 5-band Equalizer circuits with a single IC BA3812 L. a...
The circuit takes Vin, passes it through a SMPS with two MOSFETS (driven by the ir2104 that dies)...
I have no experience whatsover with building controllers and have no clue on how to start. I...
This is an application of what`s known as "random fire" technique for full phase control. The...
This circuit uses just one IC and a very few number of external components. It displays the audio...
Here we define 7 levels in thereservoir. The sensed values are connected to an encoder circuit....
When a gas leak occurs, a gas leak alarm must detect the problem immediately and issue an alarm....
Circuit is a very common three-terminal linear regulator expansion flow circuit, when we actually...
A very simple forward and backward drive motor control electronics projects can be designed using...
These two amplifiers are of very good quality, simple and economical in their manufacture. They...
