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.....

Relays are devices which allow low power circuits to switch a relatively high Current/Voltage...
This circuit uses a small microphone to capture the sound and some transistors to generate radio...
In the form it appears the theoretical circuit of filter. In first glance we see three different...
The RGB blue box turns your PC"s RGB-monitor screen blue at the flip of a switch. That is, it...
Many applications require highly efficient negative-voltage post regulators with low dropout...
If your circuits experience frequency overvoltage conditions, continually replacing blown fuses...
This circuit employs a synchronous demodulator to separate a 1 KHz signal from noise and measures...
This is an easy to build X-Y oscilloscope. To try this an ATmega324P and two KAD0820 (same as...
All coils are designed using an inch diameter pvc pipe using 20 gauge insulated hookup wire, L1...
With simplicity being the goal, brain-wave goggles can be constructed from suitable eyewear, such...
One of the goals of Movable Party is to provide an interactive experience for...
Distributed power systems are prevalent in telecommunications, networking, and high-end server...
The meter came from eBay, and has a 1 mA full scale movement. It was already marked 0 to 100. I...
The LTC3221 family are micropower charge pump DC/DC converters that produce a regulated output at...
To build a GaAs FET preamp that has good gain and extremely low noise from readily available...
