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.....

I just finished a half duplex serial asynchronous link from a simple PIC circuit to the RCX. It...
This machine essentially does three things: It controls the process temperature, provides...
The LRC input network limits the anode dv/dt to a safe value—below 30 V/jus. Rl provides...
Alright, so I had some post-publication weirdness following my last post, and it took me a few...
Voltage regulator ICs (78xx series) provide a steady output voltage, as against a widely...
This easy as well as cheap but effective device is mainly intended for your ease to leave your...
Project using Sparkfun`s IOIO for Android ( ) where power consumption is a concern. The IOIO...
This is a circuit for antenna UHF TV that can be give 15dB preamp. This circuit is built by...
Here is a remote operated spy robot circuit which can be controlled by using a wireless remote...
Take a good capacitor, around 100 or 1000 microfarads, and connect a small resistor, 10 or 5...
For this project, we are going to charge a capacitor with voltage and then have the capacitor act...
The VNGBOX micro needs to produce a very accurate, high resolution and very noise-free DC control...
Human approach detector circuit is composed of integrated operational amplifier, gate circuit and...
As shown for the basic application circuit thermistor. Figure (a) of the basic temperature...
CS3843 and CS5101 constituted by the output of 5V/3.3V switching DC power supply circuit as...
