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's operating principle is that if you make a pulse width proportioal to inductance,...
Use a pair of Maxim"s 5V-powered MAX231 RS-232C transmitters as drivers to obtain a 2-color LED....
The output of the CA3179 is fed through the Dl!Q1 circuit. Those components serve to boost the...
S2 is used to initiate timing. A light-to-dark or dark-to-light transition stops this timer,...
When you need connect your Microcontroller Project to COM port in PC you need RS 232 converter....
The KA2284 are a monolithic integrated circuit disigned for 5-dot LED level meter drives with a...
Person see the website wants DC Volt adjustable Regulate 1. 2V to 12V current 1-2A sizes at the...
The A2045 uses the same circuit as the A2052. Instead of mounting with three snap-top standoffs,...
We are planning to use a Programmable Logic Device to control our seven-segment displays. This...
The circuit mentioned here is a small easy to build Intercom circuit using one LM386 IC one...
Whatever past project these were used in obviously required three cells to be wired in parallel...
FIG. 283 is a blackout emergency lighting controller, it is only the external side in the two...
