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.....

This circuit is intended to indicate the power output level of any audio amplifier. It is simple,...
A current source that attains a resolution as low as 10 pA is useful in applications where a...
This circuit is useful in amateur radio VHF and UHF work where a mast-mounted antenna preamp is...
Flame, gas and smoke detector for fire alarm. You can combine this circuit with alarm circuit....
There are a lot of alarm systems on the market but you might be inclined to build your own. This...
This flip-flop circuit is a free running/astable multivibrator one, with bases and collector of...
Here is a simple 1KHz audio distortion meter that can measure the Total Harmonic Distortion (THD)...
The basic techniques of designing electro-mechanical systems and to gain the knowledge on tuning...
The battery should charge up to 14 volts. A reading of 10. 7 volts indicates that one cell is...
The TRIAC is a three-terminal device similar in construction and operation to the SCR. The TRIAC...
The inputs of the 74LS153 chip were mixed, which caused the address block decoding to fail. By...
Fly back transformers are commonly found in television sets and can put out 50, 000 volts, enough...
