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 circuit is used to convert a mono audio signal into a stereo signal that can be panned...
Plug an ATtiny12 into the 8 pin socket and hold down "GO!" button. The LED will come on at the...
This circuit will allow you to set the gain of two stereo channels to the same level. The signal...
When power is applied, the thermistor, a negative tc device, is at a high value. A1 saturates...
Sound or light sensors corniected to J2 produce a voltage that is amplified by ICl-a and ICl-b....
The Ping) is an ultrasonic range finder from Parallax. It detects the distance of the closest...
In this page we will introduce a great project designed by Toon Beerten. His project named "DIY...
A simple calling bell circuit that can be used in small offices to call the office boy using an...
This page describes my modifications to the RIG RX-2 receiver which enable it to be controlled...
ASIC design choosing highly integrated, low-power, short development cycle to complete this FPGA...
By the pLPC1342V and NE (two company names and fever on the tube amplifier circuit 2SA1227A...
Europes leading SGS-THOMSON STMicroelectronics recently introduced a tone quite new to the...
Exars XR-L555 circuit typical power consumption is 900 W, the power supply voltage of 5V,...
