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.....

Here is an interesting circuit for a magnetic proximity switch which can be used in various...
The output of a video amplifier is differentiated before being fed to a Schottky comparator. The...
This project has only a few modifications from the Single Chip, Four Channel Datalogger article,...
The schematic diagram come from circuit: Adjustable High Voltage Power Supply 0 to 1000V power...
Normally home appliances are controlled by means of switches, sensors, etc. However, physical...
The circuit diagram shown here is of a 2 x 60 Watt stereo amplifier based on the LM4780 from...
Using a single 555 Timer IC and a small transformer to generate a high voltage, this circuit will...
It uses a 555 timer wired as an astable oscillator and powered by the emitter current of the...
Wrap hundreds of turns of magnet wire around the paper tube. Connect this home-made inductor in...
This circuit uses a 555 timer to generate a sawtooth voltage waveform across a capacitor, then...
It makes sense to build your own individual joystick. Especially the flight simulation...
When listening to music at low volume levels, bass and treble frequencies are attenuated more...
Circuit current is greater than the load carried by the rated current meter, the user...
Dimming control circuit as shown in FIG. Single-chip I/O port sinking method to achieve control...
