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.....

R2 sets the circuit"s threshold. When the light intensity at PCI"s surface is decreased, the...
Ll and L2 form a tuned transformer. About a 1:3 turns ratio is optimum. L2 and CI tune to the...
White Light is an interactive sound and light installation. It is part sculpture, part musical...
The circuit even has a current limiting feature which is a more reliable system than most...
There are occasions when you want to view your video clips taken in your digital camera on your...
Summing amplifier or an adder is used to sum two signal voltages. Voltage adder circuit is a...
One of ZiLOG`s most popular Z8 One Time Programmables (OTPs), the Z86E02 features a 512-byte...
The circuit is built around two 555 timer ICs. U1 and U2. U1 is wired as a variable duty cycle...
While most commercial grade signal generators offer more than just outputting a sinusoidal...
When spun rapidly between the fingers, a bipolar stepper motor will generate around 10VAC. If...
Four 595s together to drive 7-segment displays and alsoadded code to acceptinput from the PC....
Built for Birkbeck, the microscope controller is a open source stepper motor driver. It uses an...
NS LM4766 US company launched a two-channel power amplifier integrated circuits, each channel on...
1/0 defined PLC Table. Its input signal path 13, including: 1 motor starter button. 2, 3, 5, 7,...
