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 charger described in this article can charge packs of 4 to 7 cells with capacities ranging...
This sensitive sound operated switch can be used with a dynamic microphone insert as above, or...
This inexpensive dc supply-voltage monitor sounds a warning when the voltage falls below a preset...
In operation. the alarm circuit allows a 0-47 second time delay, as determined by the Rl/Cl...
Although ceramic resonators are a good choice for low-power, low-frequency clock sources (if you...
Hall-effect switches have several advantages over mechanically and optically coupled switches.
Ql, Q2, and the associated circuitry form a modified astable multivibrator in which the loop...
A MOSFET that drives a load. The load has a sense resistor in its current path and its voltage is...
The Micromag3 is a 3-axis magnetometer that measures the strength of magnetic fields in 3...
This is a color sensor Circuit Diagram. This circuit will sense 8 colors that are:, green, red...
The thought of going to 24 GHz was far from my mind back in the summer of 2002. We had just come...
It plugs into the USB port and is just the shot for checking motherboard switch and jumper...
This circuit is a dual low/floating/high logic state detector which enables you to see the logic...
An 8-bit password is the input to this system. The password entered by the user is compared with...
AD7714 Typical application circuit is shown in Fig. UDD, UDDA end of the AD7714 can be connected...
38. The solid state phase failure relays for three-phase AC phase failure monitoring, protection...
As shown for the simple high-frequency signal generator. Change the LC resonant circuit...
