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 is completely conventional, and has been around almost forever in one guise or...
Soundblaster soundcard series (SB16, SB32, AWE32 and AWE64) have all a microphone input designed...
This circuit can generate voltage 15V. In these circuit LM340 input voltage must remain within...
Circuit schematic above is one of the voltage inverter circuit, starting from 6-Volt input on the...
As far as we are concerned we are looking for a function generator or a VCO (voltage-controlled...
The circuit is built using ICM7217 integrated circuit, manufactured by Intersil, which contains a...
Power demand in portable designs CAN require in some specific application more than 1 A. A method...
The normal telephone bell, at times (specially during night when one does not want to be...
The circuits in Figure1 and Figure 2 exhibit certain advantages over the circuit shown in the...
How to add an AC-3 RF output to older laser disc players. Finally I was ready to try it myself....
What do you do with those old 2-Meter FM rigs that don`t have any CTCSS tone capability Well, you...
And vehicles from the same period, the generator without excitation, no voltage generator bus,...
As shown in Figure is a circuit diagram of an enhanced lock the AE1169. AE1168 enhanced when the...
Circuit shown in Figure 1-560 RPi is treble control potentiometer. Because C3, C4 is larger than...
Current Transformer H11-3 need be made. Choose not less than 2W transformer core, the first...
FIG VDI ~ VD4 form a bridge diode rectifier, a full-wave transform the 220V AC pulsating DC, all...
