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.....

Pure A class is the most simple topology for designing an amplifier! The tube or the power...
The board has been initially developed to learn with CAN, so a CAN transceiver is available...
This wave shaper needs an input saw that goes from Vss to (ideally) Vdd. It works well with the...
This circuit does not require an output transformer or an output coupling capacitor; the...
This circuit is designed to detect a low light level at the sensor, amplify the signal, and...
Voltage to frequency is very useful in many situation, such as transmitting temperature...
Here is a project Device switching using password by innovative group Dreamlover technology,...
This is an electrical propulsion method with no moving parts which applies to any conductive...
I m planning to construct a frequency synthesizer circuit and i found this circuit diagram..but i...
You need not be disappointed next time when your digital camera shows low battery indication...
Version V2. 9 supports also GPS-receiver with ANTARIS chipset and simultaneously using of...
Ultra simple circuit of the tilt sensor alarm presented here can be fabricated using readily...
Channel 0 of the Dual Voltage/Current Source (DVI) was used as the input. Input levels of +3V and...
Converting my 1958 Buick over to electric wipers with delay and automatic "wipe on wash"...
I found one circuit diagram, on one russian site, freeenergylt dot narod2 dot ru/Aidas. Question...
