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 low cost, crystal-controlled oscillator uses one TTL gate. Two factors ensure oscillator...
This amplifier circuit has a pretty good quality. Of course the sound quality, although this one...
Voltage regulator ICs (78xx series) provide a steady output voltage, as against a widely...
The Dogm-graphics-module should be connected to the Arduino board as shown below. Pin 12 (MISO)...
Using a PIC12F675, up to 5 outputs can be switched sequentially using a standard Remote Control...
A 6 watt audio amplifier circuit using TDA2613 is shown here. TDA2613 is an integrated Hi-Fi...
The design is based around a pair of 433MHz wireless modules. These can be bought pre-built and...
You can use any PIC microcontroller that has an ADC and enough memory to hold the program. The...
Here`s video transmitter circuit is working on the UHF channel frequency 470-580 MHz channel...
The first was interested in a flexible preamp for use with a high-end acoustic guitar with...
You might find yourself needing a low power H bridge for driving a motor like I once did. The 555...
Using the LM2876 audio power amplifier circuit can be designed a very simple high efficiency...
The power that is used for realignment is a loss as far as the rest of the circuit is concerned....
This experiment may be built using only one 8-position DIP switch, but the concept is easier to...
