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 circuit in Figure 1 accommodates lower cutoff frequencies without sacrificing the...
The alarm will switch off when the 4 keys connected to "A,B,C,D" are pushed in the right...
This is a single channel (on / off) universal switch that may be used with any Infra Red remote...
This fucntion gernerator IC is specified to work to 20 MHz. So far, this unit works nicely to...
Here are some 3V to 9V DC converter circuits that were requested by some of our visitors. It may...
For some ten years Texas Instruments have been developing solid state speech technology with the...
As a wideband PLL FM Demodulator the UTC L2572 is intended for application in satellite Tuners...
The LM1830 fluid level detector circuit is a device intended to signal the presence or absence of...
I hook up a tesla pancake coil in series with my bifilar wound coil to generate the resonance and...
For this special Halloween project we built a spooky candy bowl that lights up when an...
This little aid was originally designed to test the Shutter Time Meter. This meter was...
AD7s23 is an 8-bit multiplication DA converter, the output voltage of the analog input and the...
As shown, the digital thermometer by the temperature sensor, single stabilizing circuit, counter...
DC generator automatic voltage regulator circuit is shown in Figure 7-53. This circuit is used to...
