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 uses a CA3130 BiMOS op amp as the sample-readout amplifier for the storage...
The flash type converter is the simplest and the fastest type of analogue to digital converter....
So I wasn`t really in the mood of making and coding the timing controller for the PCB laser...
30 incandescent lightbulbs be controlled by my arduino uno on 3 channels (10 bulbs to a channel...
A circuit that fires a relay when it detects audio pulses from one channel of an mp3 player. I`m...
This circuit detects spikes in voltage around 18v. It is used to detect when a battery becomes...
The Digital-Analog-Converter fetches one of 15 parallelly pressed keyboard keys from the digital...
The 1812 Overture by Tchaikovsky lasts for 14 minutes and 40 seconds. It is scored for a...
Dynamic‚ip-‚ops ignore pulses at their inputs that are shorter than 40 ns or do not have TTL...
This circuit, which was developed to monitor the traffic of bumblebees in and out of the hive,...
The project started with a request from a fellow member of the Long Eaton Club, Tony Bowler. He...
The TRIAC is a three-terminal device similar in construction and operation to the SCR. The TRIAC...
DK-5A, 5D, SDb control box, all with a thermal electromagnetic overcurrent release, the circuit...
