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 was submitted by Adam from Canada who is still at school. I have provided the text....
Note first the battery to be treated at the center of the figure. It is connected to contacts of...
The battery powered light turns on easily, stays on for just a few seconds, and then turns off...
This circuit holds on the internal light for approximately one minute after the car doors are...
This circuit determines whether more than one input in a group of digital inputs is active. It...
If you are busy and cannot answer or do not wish to answer your phone, this circuit will give a...
Typical F71T12 100 W bi-pin lamp used in tanning beds. Note the (Hg) symbol indicating it...
The wireless transmitter ambit congenital about transistor T1 (BF494) is a basal low-power...
These two headlight reminder circuits are easy to install and operate on the KISS (Keep It Simple...
Here is the circuit diagram of an adjustable voltage regulator using IC L200. L200 is a...
The problem is when i connect the 8051 to the encoder the data send is not received at the...
This circuit was developed since a number of visitors of this website requested a timer capable...
Many of us who use GTX 900 MHz radios to work amateur repeaters are well aware of the erratic...
As shown in FIG hypnosis massage is pocket-sized electronic timing circuit with two 555 timers...
