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.....

Just a handful of components builds an 8-pin microcontroller based circuit for temperature...
This project is a self-contained serial terminal using a PIC16F84 microcontroller chip, an...
This circuit uses a couple of Op-amps to produce an interesting sound effect. The left hand CA741...
I use the lm10 IC because it has a reference voltage and that?s useful for dc power supply. With...
Opamps are very useful. But one of their major drawbacks is the requirement of a dual supply....
This circuit uses a type 741 op amp as a voltage comparator. One input of the 7.41 is connected...
The circuit uses a four-bit latch (Ul). What makes the circuit sequential is that the set input...
This UC3825 IC, which is manufactured byTexas Instruments, is a high-speed pulse width modulation...
This heat detector alarm electronic project is designed using the UM3561 sound generator circuit...
Assuming I can get 5V in example after adjusting the pot in real use, will the 240 ohm resistor...
This page is oriented towards the USA marketed radios, simply because it was compiled by USA...
A field strength meter is a very handy tool for locating a transmitter. A sensitive field...
