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.....

Safety devices like fuses provide protection against excess current, but do nothing for...
The ULN2003A and Zener from the driver board inside the same device. It`s a 5 wires motor, but...
This circuit serves to show the speed of the vehicle in kmph. An opaque disc is mounted on the...
This circuit diagram is a UM66 based touch sensitive musical bell. The circuit is built around...
The AD322 is an 8 amp G-Scale DCC decoder. The notes below may be of benefit to owners who wish...
The problem with amplifying weak radio signals is that you also amplify the noise. What you can...
The Cmos 4060 IC has two built-in inverters - at pins 9, 10 and 11. They must be wired together...
Typical application circuits Zheng brick SRS5250S constitute processing shown in FIG. 9-41....
Almost open collector two outputs, open a withstand voltage of 60V, continuous conduction current...
Ammeter measuring current in the circuit, the need to break the circuit in series in the circuit...
As shown for the basic connection circuit ISO113 signal and power supply. Each power supply...
Circuit is shown, which consists of a DC voltage regulator circuit, the delay circuit,...
Circuit shown in Figure 3-164. The circuit can be manual and automatic two ways. During startup,...
