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 Model HC 6 Headphone Console is a six channel headphone amplifier, consisting of six stereo...
When using a regulated supply to reduce a supply voltage there is always the danger of component...
Two NAND gates are used for the oscillator, and two as the control. If the two-tone speed needs...
This regulator is for the purpose of controlling a dc generator. The field configuration is that...
First thing`s first, what software to use I went with CadSoft Eagle primarily because there are...
15 Watt switching power supply schematic diagram. Pulse transformer T1 is performed on the...
Nearly always when a remote control doesn`t work, the underlying problem is elementary: the unit...
From the discussion made so far on the filters, it may be concluded that in the stopband the gain...
The liquid detector is a detector with liquid alternating voltage and can be built using some...
With IC SLB0586A from Siemens you can build a simple touch light dimmer circuit that will allow...
The circuit is a broad band amplifier which will take the video signals from your VCR and will...
A power filter is a device you put ahead of something like a GPS and MP3 player and or radar...
Now, let`s re-examine the function of the TRIS registers. The TRISA and TRISB registers control...
