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.....

A LED is defined as "light-emitting diode: diode such that light emitted at a p-n junction is...
A bar column of LEDs is arranged so that as the audio signal level increases, more LEDs in the...
Universal motors and shade d-pole induction motors can be easily controlled with a full-wave...
When activated, the transmitter sends out a 49.890-MHz, AM rf carrier. The.receiver detects,...
The 15 w class B audio amplifier circuit shown here is a simple class B audio amplifier based on...
The circuit is designed to be low cost. It uses a PIC12C508 to perform the control functions and...
This weekG•s plan is to build a device that warns of the potential of a knockdown the process by...
This design fulfills these requirements by means of a variable gain microphone preamplifier built...
Many people experienced sleeping well in natural surroundings, into a tent or a wooden hut. This...
The Smart Ballast IC is designed to control a Fluorescent Lamp Ballast including a Discontinuous...
The purpose of this circuit was to create a ring in which LEDs or Lamps illuminate sequentially....
To obtain such a monitor it`s enough to connect a resistor in series with the bulb and connect at...
As shown in (a), KAi, KA2, KA3 intermediate relay, connected to the outlet end of the...
Electronic switch is a multifunctional preamplifier. It consists of five-way touch electronic...
Electronic temperature control circuit on an imported car air conditioners. Operational amplifier...
This transmitter of 255W is depended on the coils we put at it to work in both the middle and the...
