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.....

A TDA1024 electronic thermostat senses soil temperature via thermistor R6. The circuit uses...
April 2006 was the twentieth anniversary of the Chernobyl reactor accident. In the days following...
This circuit is quickly charging the battery. If you need a faster charger, this circuit is...
This page documents an older version of the project that proved very unreliable. This is (still)...
Since you say that with my PWM circuit the current consumption of the inverter shoots to a...
Based on this `manual` PCR machine I built a few weeks ago, the Light Bulb PCR machine uses a...
This was actually used to program my Digital Voice Recorder which I made for my VI sem project....
Common to all the devices is that they emit intense red light with a wavelength of 660 nm. Some...
Used a 12V motorcylce Battery and an ignition coil of a car. A microcontroller produces some...
The LM1036 is a DC controlled tone (bass/treble), volume and balance circuit for stereo...
Sun tracking systems are very effective in increasing the efficiency of photovoltaic (PV) arrays,...
The circuit is great for controlling the power delivered to a device such as a fan, LED`s or even...
Four 595s together to drive 7-segment displays and alsoadded code to acceptinput from the PC....
Circuit work process is: When the momentary switch S between, since the voltage across the...
