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 tool is based on a NE555 (or LM555) timer i.c., wired as an astable multivibrator. The...
This is an IR transmitting circuit which can be used in many projects (I designed this to try to...
A high impedance input is provided by Ql, a general purpose field effect transistor
Using an ISD1016 audio record/playback chip (Information Storage Devices, Inc.), this circuit...
This flashing light circuit uses triacs to generate an intermittent light with patchy frequency....
It is a low frequency Wiew bridge sinusoidal oscillator for the audio range with very low...
The following is a copy of an article posted by Wilf Rigter to the original BEAM email list and...
Many consumer products using white light LEDs for illumination and backlighting provide gradual...
This article is of interest only to readers whose bicycle lights are powered by a dynamo. The...
The Slave Flash Trigger is switched on/off by pressing the push button. When switched on, one to...
As some of you know, the Traynor YBA-1 is a very close derivative of the classic Bassman/JTM-45...
An integrated circuit`s response to fast transients on its input supply is often an important...
Vacuum tube tesla coils operate in a continuous wave mode of operation, continuously providing...
The schematic for this project is much more complicated than previous projects. There are four...
As shown in Figure 3-30 to promote the use of IC LA4425 stage power amplifier, a pair of power...
Automated instrumentation wiring using interference filters for the inverter is not as harmonic...
