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 circuit shown in Figure 1 uses only two ICs, and has a bandwidth that is adjustable from more...
Using ADF4007 high frequency divider PLL synthesizer can be designed a variety of communications...
Wolfram SystemModeler ships with model libraries for a large selection of domains such as...
It can give ample light even for reading purpose. Capacitor CX along with diodes D1 through D4...
An Arduino Uno connected to two IR transmitters and respective receivers. Basically, when one of...
All you need to do is supply a resistor (I used 200 Ohms, with a 3. 3V supply) to the power line,...
This is the easy build surround sound processor circuit using the digital delay process method....
Analphanumeric low cost LCD Display is very essential for may small and big projects to...
We will bypass the mechanical snooze switch on top, and instead turn the alarm clock off in a...
Colpitts oscillator. Its frequency depends on the capacitance of the vary cap diode. The center...
This project takes after the VGA-to-Scope converter by using composite video rather than VGA...
This self powered interface circuit electrically isolates the TxD and RxD lines from the PC...
A Transcutaneous Electrical Nerve Stimulation (TENS) device is, put bluntly, a machine for giving...
Boosters are not buffers! While it is possible to make a booster that also provides a buffering...
Originally, the tank cost around Php400 but then it was sold at around a hundred less. Without...
When the switch is on, the seismic alarm isin detection condition. When there is no earthquake,...
741 op amp can be used as a voltage comparator. Non-inverting input and a zener control source....
