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 circuit is built around an LM339 quad comparator, Ul, which forms the basis of a Schmitt...
This circuit is a static SCR switch for use in a dc circuit. When a low power signal is applied...
This is the figure simple telephone ring tone generator circuit designed using only a few...
4 Stage FM transmitter circuit diagram. It uses four radio frequency stages: a VHF oscillator...
Here is a able ambit of IF arresting architect which may be of absorption to radio hobbyists and...
This is a minimal circuit which I built to individual of my audio amplifier projects to control...
The system regards DSP56F826 chip as the key control module, uses the sensory chip of CMOS...
Constructing a robot or should i say a vehicle dat uses 2 motors. I managed to get sum referance...
The AAT1275 evaluation board provides a platform for test and evaluation of the AAT1275 switching...
This circuit will allow you to turn on any piece of equipment that operates on 115 volts ac. The...
Is possible to syncronize the leds so that first, the speakers are still playing aloud, and two,...
Although not a new device, the LM317 is still a high-performance regulator. Its output voltage is...
Commonly used high sensitivity header is actually using microampere meter, use it to produce...
Dimming control circuit as shown in FIG. Single-chip I/O port sinking method to achieve control...
