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 LM3915 is a monolithic integrated circuit that senses analog voltage levels and drives ten...
This is a handy, easy to build general purpose 50 watt amp. The amp has an input for a radio, TV,...
With all DHT stages (all tubes from Svetlana 1970-s). OK, the input/splitter are not DHT`s but...
The circuit presented here is a simple audio/video transmitter with a range of 3 to 5 metres. The...
This is a handy companion for a digital voltmeter. Its allowed me to do a lot of things I used to...
This circuit uses only one IC, produces a pleasant tone, and sports a single control for...
A TDA1024 electronic thermostat senses soil temperature via thermistor R6. The circuit uses...
The Maya used several calendars simultaneously. One of them called the "long count", is a...
With this circuit you can power-ON or Power-OFF a lot of electric/electronic devices such as aDSL...
Today i want to share with you all my water sensor. This is my second successful project when i...
I have an almost mint condition Fisher 800b hi-fi amplifier that I want to convert into a mic...
The distortion produced by a typical solid-state Class-B power amplifier is shown to consist of...
This is a new gear for Radio Direction Finding (RDF) known as FOX HUNT or called Transmitter...
The range of this FM transmitter is around 100 meters at 9V DC supply. The circuit comprises...
The LTC3722-1/LTC3722-2 phase-shift PWM controllers provide all of the control and protection...
