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 is another kit in our self-sufficiency range. We also have a 12v fluoro inverter kit for...
The circuit is composed of a relaxation oscillator formed by Q1 and an SCR flip-flop formed by Q2...
Gates Gl and G2 together with resistors Rl and R2 form a simple voltage monitor that has a trip...
It is very rugged and reasonably power amplifier circuit that can be used for any audio...
For some ten years Texas Instruments have been developing solid state speech technology with the...
Nowadays the most commonly available headphones have an impedance of 2 G— 32 ©, this relatively...
The CDCF5801 provides Clock multiplication from a reference Clock (REFCLK) signal with the unique...
Using high voltage transistors can be designed a DC power supply that can provide a supply...
This little phono stage completely trounced my sub-mini phono preamp. The phono preamp was...
Inverter or ondulator, is an electronic circuit used to turn direct current (DC) into alternating...
I designed and built this Ring Counter Clock in 1970. The base is a 12" diameter/2" thick block...
The Sovtek 5881s that come in these amps are cheap and sound like it. Change ALL tubes. Get a...
322 monostable multivibrator is cross-connected, when run under non-steady state condition...
As shown in FIG constituted by MAX639 + 5V fixed output buck power conversion. MAX639 is a...
BA532 and low frequency power amplifier circuit for OTL circuit, output power up to 5.8W,...
Because of the high rhythm of peoples lives. Tense, intense competition, many people suffering...
