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.....

LochMaster is a developers tool for stripboard projects. It has useful functions for designing,...
If you are busy and cannot answer or do not wish to answer your phone, this circuit will give a...
Suitable for monitoring an amateur band or a segment of the radio spectrum, this simple adaptor...
The Link circuitry is simple and efficient, employing just two ICs, half a dozen transistors, and...
The ambit declared actuality is that of a metal detector. The opera- tion of the ambit is based...
This handy, pocket-size mobile transmission detector can sense the presence of an activated...
As they did with the monotron synthesizer, Korg has quietly released schematics for its the...
Mode control of the average current CMC Require it in order to control the total waveform of...
This is a square wave oscillator (digital, like 8-bit music). It`s based around the LM386...
You cannot beat the Chinese. The project described in this article is a ready-made item from a...
Conventionally a MOSFET with a voltage rating of 1500V or with a Half-Bridge connection using two...
Ensure that the 12V(yellow) wire is connected to the right of the D-connector(as seen from...
The Current Sensor Board contains an Atmel AVR AT90S8535 running at 8MHz which samples six ADC...
200mA peak current letter phone photo camera flash circuit, using a AAT3110-4.5 electrical...
Common collector amplifier circuit DC and AC path b (3) common-collector amplifier circuit DC...
