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 is a compact three transistor regenerative general coverage receiver with fixed feedback....
The controller is quite (actually very) simple. An input buffer ensures that the input impedance...
The figure shows the use of a CD4016 analog multiplex to multiplex the digital outputs back to...
In applications where the rejected signal might deviate slightly from the null on the notch...
The ramp generator, an inexpensive alternative to commercial function generators, provides a more...
Laser-receiver circuits must bias their avalanche photo diodes (APD) to achieve optimal gain....
Today I has 12V to 5V 3A DC converter step down Regulator circuit come to deposit. In sometimes...
This Sealed Lead Acid Battery Charger is deigned using the LT3755 DC DC controller. The LT3755 is...
The simplest way to drive stepper motor having lower current rating is using ULN2003. The ULN2003...
The basic digital circuits are Flip Flop and Counter, both are here. This circuit can be cascaded...
The basic Geiger counter circuit is identical to the previous circuit. The revision is the adding...
The video-mixer no longer requires a supply voltage. This supply voltage could introduce moire...
