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 040904C version of the code has a larger UART receive buffer and supports two pushbuttons...
This circuit uses a CA5422 dual BiMOS microprocessor op amp. The bootstrap amplifiers minimize...
Video-signal amplitude can be measured with this simple circuit, which is basically a modified...
I have built several boards using the bq51013 EVM receiver circuit and a TPS61085 boost converter...
This LM723 variable power supply circuit design is a very simple variable power supply that will...
The whole project was developed on a friend`s request. Its purpose was to remotely monitor the...
After all job of building the prototype and making the sketch work, it`s the time to build the...
CPU NatSemi Geode 200/233/266/300 MHz (default 233 on-board) or and follow Geode link. VGA/LCD...
UART, GPs This application note shows how to combine a GPs module SC16C2552B into a navigation...
The 555 Astable generates a clock for this circuit, an oscillator giving a square wave output at...
The 555 timer will put out positive pulses. The pulse width is inversely proportional to the...
This is the automatically search schematic diagram of FM radio. Its core component is a TDA7088...
This is door knob touch alarm for your home security purpose. The alarm will be activated when...
