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.....

Audio light modulations add to the enjoyment of music during functions organised at home or...
Here's an effective little combination lock that you can put together in one evening's time. To...
Take strobe-flash pictures the instant a pin pricks a balloon, a hammer breaks a lamp bulb or a...
The use of a switching transistor (like a 2N2222 or 2N3904) allows use of the CD4511B with a...
This is the cheapest 150 Watt amplifier circuit you can get, I think. Based on two Darlington...
Oscillating circuit (coil) are made on a ferrite bar. If you wish to listen long waves winding...
The circuit works like this: Normally the LED is powered dimly through R1 and R3. SW1 is the...
This is a circui for audio frequency meter. This circuit uses 555 IC as a mono stable multi...
The hardware is just an Arduino board connected via USB to a laptop. The Arduino appears as a...
A Darlington would perform even better, but the circuit would be slightly more complicated. (See...
When the weather is hot with the sun beating down the car won`t start and radio, keyless entry,...
Most off-the-shelf car battery chargers cannot not be left connected to the battery for long...
The nixie tube clock consists of a high voltage power supply, seven rings counters and an Atmel...
IR remote control for my Nikon DSLR camera. Not that I absolutely need one, surely I don`t need...
The design of the charger is similar to that of many commercially available chargers. The charger...
Adjustment potentiometer RP, can change the over-voltage limit setting. If the DC power supply...
Class A power amplifier distortion, although low, but its low efficiency and output power is...
