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.....

Well the most common use is in a solaroller which is a small wheeled car that charges up and then...
This antenna is the result of long term development and user feedback. All ATL-3 loop windings...
This zero-crossing detector uses a dual LM393 comparator, and easily controls hysteresis by the...
Input signals from the power line are coupled through C23 and R19 to the input filter network....
A fixed current flows through any load that is connected between the positive supply and Ql"s...
The electromagnetic ring launcher is comprised of.four subcircuits: a clock circuit (built...
Capacitive touch sensors are based on the electrical capacitance of the human body. When, for...
The series of light switches this time slightly different from the stress of work. The series of...
The full wave phase control circuit below was found in a RCA power circuits book from 1969. The...
This paper will guide you through how to do just that. We`ll review a simple computer system and...
The metal detector circuit shown here must represent the limits of simplicity for a metal...
This Hi Fi stereo preamplifier circuit is built with TDA1054 IC from SGS. TDA1054 is a 16-pin DIL...
The first test circuit (see figure 5) is about the simplest circuit that can be designed around...
FIG VDI, VD2, Rl and Cl form resistance voltage half-wave rectifier circuit, the output DC...
