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 voltage measurement is very general in electron technology at present, accuracy requirement...
Color sensing with camera and sufficiently powered processor running image histogram logic (or...
This is the story of the Fredbox, a rig that first saw the light of day in 1974 in Cambridge. In...
This circuit operates an automotive windscreen washer pump to fill a 20-litre drum from a...
The mixer circuit above has 3 line inputs and 3 mic inputs. The mic inputs are suitable for low...
This circuit takes advantage of the voltage drop across bridge rectifier diodes to produce a...
This also Not a Cell phone jammer. Jamming a Cell phone is similar on its principle, but totally...
The phone is a Siemens S65. The official charger that came with the phone says 5V at 420mA....
The NI 655X is a versatile high-speed digital product that can interface to many different...
The circuit is built around a 555 oscillator (IC1) and an LM386 audio amplifier (IC2). The 555...
Cats are predators of rats, the use of electronic devices to simulate mew Repeller is an...
Circuit as shown by 555 and the light emitting tube. 555 and R1, R2, C1 composition astable...
Circuit shown in Figure: MAX6698 maximum temperature with three transistors (VT1 ~ VT3) and...
