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 consists of 6 building blocks and the first is the inverter between pins 1 and 2....
The circuit can control up to 6 kW of heating, with moderate gain, using a 25-amp triac (SC260D)....
Temperature control is achieved using the REF-02 +5 V Reference/Thermometer and a CMP-02...
Using the A3952S stepper motor controller designed by Allegro MicroSystems can be designed a very...
This circuit is the High Input Voltage regulators, which generate voltage 5V. In these circuit...
DC To DC Converter circuit used to be an convert voltage DC to DC with different concepts. DC to...
A solar panel is, as the name says, a panel which collects solar energy and converts it to...
The AN7147 Dual 5. 3-watt Audio Power Amplifier from Panasonic is listed as a replacement type`...
This device produces high voltage pulses discrupting muscles and nervous sYstem, leaving anyone...
CD4051BMS, CD4052BMS and CD4053BMS analog multiplexers/ demultiplexers are digitally controlled...
A localizer without GPS. We remake the old device with the cheaper SimCom module SIM900. In the...
Those of you who own large 500 watt and higher Astron linear power supplies, and even large HF...
The great network of telegraph wires that once enfolded the nation like a cobweb has vanished...
The purpose of this project is to visually communicate the effects that frequencies have with...
WB5LUA described GaAsFET preamps for several microwave bands which included an active bias...
Annual listing of watermelon season, many people lack Yin Chi intuitive judgment raw and cooked...
Circuit is shown. Group 4 analog electronic circuit switch (S1 ~ S4): S1, S2, S3 for parallel...
DS1620 with a microprocessor to monitor temperature, by opening or closing the fan can be changed...
