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.....

Having found an u664b prescaler chip (Telefunken) from an old tv-tuner , I decided to build a...
Conversion of triangle wave shapes to sinusoids is usually accomplished by diode-resistor shaping...
This rf detector can locate low-power transmitters (bugs) that are hidden from sight. It can...
Field Strength Meter Using A Biased Schottky Detector A temperature compensated Schottky diode is...
I bricked my iPod shuffle, seems that the controller chip for the mini jack got wasted as it...
AVRDude is excellent program for burning hex code into microcontroller. USBasp is awesome USB...
The ambit of frequencies for the FM advertisement bandage is 90MHz (MHz = Megahertz or 90 actor...
The circuit presented here can be used for connecting two telephones in parallel and also as a...
This circuit SP6691 has been designed to provide a high output voltage with a lower voltage boost...
This timer circuit is similar to the 5 to 30 minute timer except that when switch S1 is closed,...
This simple robot, which responds to light and avoids obstacles, can be built without using a...
This is a 9vdc powered LM13700 dual transconductance op-amp based filter very suitable for...
The UTP Cable Tester can be used for many purposes. Mainly to test a UTP network cables of...
Your HVsupply will work, but for your own safety and to avoid accidental damage to your circuit...
The notion of "crystal radio" is strongly associated with huge antennas and radio broadcasting on...
