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.....

Measures 10mV to 50Volt RMS in eight ranges. Simply connect to your Avo-meter set to 50µA range....
This is a very basic power failure lighting circuit based around a relay. This simple circuit has...
Photo diode outputs light current that is well proportional to input light power when it is used...
It is quite easy to get a watt or more with very simple equipment, but to get more than 5 watts...
A tapped-coil Colpitis oscillator is used at Ql to provide four tuning ranges from 1.7 to...
The circuit monitors the input to the microprocessor 5 V regulated supply for voltage drops and...
This circuit provides a regulated dc with less than 100 mV of ripple for microprocessor...
This detector is useful in sine wave squaring circuits and A/D converters. The positive input may...
A limiter circuit that requires matched zener diodes can instead use one zener with a full-wave...
The circuit can be used as a sensor that can trigger an alarm, without direct contact being made...
This began as a simple project to build a cheap phono stage for a very old turntable with a cheap...
This circuit is intended for children fun, and can be installed on bicycles, battery powered cars...
The values of LM56 Thermostat project Circuit diagram of R1, R2 and R3 for the points of travel,...
The TDA3567 is a monolithic integrated decoder for the NTSC colour Television standards. It...
An analog input is a measurable electrical signal with a defined range that is generated by a...
This circuit came from a need for a quick and dirty network tester that could be operated by...
However effective a domestic alarm system may be, it`s invariably better if it never goes off,...
I currently have three: a really old optoelectronics Opto-7000 which I don`t use much, a newer...
These versions are the original UV-3R, the UV-100, UV-100 MKII, UV-200, UV-200 MKII, UV-3R MKII,...
