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.....

The Generator cell must have reasonable surface area on the Plates to generate a reasonable...
Building a foxhole radio is rewarding and the basic setup is very simple. It is, however,...
When switch SWl is positive, the FET is turned on, and has a resistance of about 400 ohm. The...
The circuit uses a 4011 CMOS NAND gate, a pair of diodes and an NPN power transistor to provide a...
This circuit functions as a wideband adjustable AGC amplifier. With an effective bandwidth of...
The Pierce oscillator is a very simple circuit and as with the ring oscillator also uses...
This circuit has been very useful in filling a header tank for a reticulated water supply on a...
This design was born of frustration with the mic preamp in my Sony R91. It clips at ridiculously...
The idea for the project started nearly two years ago, while I was researching the purchase of a...
Here is my project on interfacing of SD Card (microSD). microSD cards are available very cheap...
This sensitive sound operated switch can be used with a dynamic microphone insert as above, or be...
The 555 Timer shown below is configured as an 555 Astable Multivibrator previously discussed....
After some small loss of field magnets can be re-magnetized porcelain filled with homemade...
