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 power drain is approximately 150 mA. IC1 provides a regulated 5-volt supply for the filament...
This divider uses a variable-length shift register, a type-D flip-flop, and an inverter. The...
2 x 18W Hi-Fi Stereo Power Amplifier based around two TDA2030 ICs. It has good input sensitivity,...
Creating a 2-bit alu. It has 8 defined functions (the functions are defined by a 3bit code), AND...
This is a very simple game circuit. You can play this with your friends. To win this game one has...
This power supply can be used to obtain a regulated power output, variable right from zero to 300...
The common wiring method had one side of the line cord going to a pin on the rectifier tube and...
The idea was to show time passing, but instead of a traditional clock face or digits or lights...
One interface that is missing in the Lego MindStorms system is an electronic ear. We don`t mean...
The MSF transmitter sends time data bit-by-bit over the 60 seconds of each minute by dropping the...
Electronic devices love accuracy. If you give them the same task twice, you will get the same...
The keypad circuitry is based around a PIC1652 microcontroller that was manufactured by General...
This board does NOT use the CTS256AL2 text-to-speech chip. [It would seem that both...
RT9179CB use power management chip power supply circuit Shown the way for the introduction of...
Clip-on current probe, such as the Tektronix P6021 current waveform for oscilloscope display is...
