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.....

Many times we needed a variety of voltages, from a battery 12V. With the circuit, we can take...
Tl is tuned to converter-output frequency Ul to provide 45-to-50-dB gain, depending on the...
In this circuit, a full-wave bridge is switched to a full-wave center tap to reduce regulator dissi
DTMF dual tone multifrequency The signal is a commonly used signalling in the telephone network,...
Most all power supplies regulate either their output voltage or output current at a constant...
I worked on developing a digital frostpoint hygrometer for measuring water vapor at NOAA. Using...
The DC Brushless Fan is the best solution for now, but some predictions are that computers will...
This little circuit is invaluable for quick go/no-go testing of just about any remote control...
This sunlight-controlled lamp uses a light-dependent resistor (LDR) as the sunlight sensor and a...
There is one slight drawback to our flashing LED program. Each instruction takes one clock cycle...
This is a little circuit that i designed that could be used for achargingcontroller or voltage...
The 555 Timer shown below is configured as an 555 Astable Multivibrator previously discussed....
The following plans describe how to build a very small tracking transmitter that can be tracked...
The FT8U232AM requires a small number of external components to produce a device that converts...
