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 Atmel Flash devices are ideal for developing, since they can be reprogrammed easy and fast....
This box is a portable transfer standard to maintain and carry with you a local time signal of 59...
Here is a schematic of a rechargeable 9-LED flashlight using two Gates SLA cells and nine LEDs....
This is a circuit that generates white noise, rolled-off to drive earphones or a small speaker....
The supply receives + 20 Vdc from the rectifier/filter section. This is applied to pins 11 and 12...
Ll and L2 form a tuned transformer. About a 1:3 turns ratio is optimum. L2 and CI tune to the...
the sound system, the massive de-sensitized, and they defeated a maximum range. This can be...
This is a similar circuit to the above and provides a 4 LED bar graph indicating the voltage of a...
This handy circuit can be used to charge from one to 12 NiCd cells from a car battery. Up to six...
Here is a simple but effective battery charger circuit using IC LM 317. The circuit can be used...
ASSP For Audio AN41240A The AN41240A is a single chip IC that uses single-hall-sensor drive on...
The original smoke alarm circuit has some problems and has left some hobbyists and students...
The 751 required turning the volume control almost to 12 o`clock before getting any hearable...
A PIC16x84 processor may be used to generate a PSK31 or FSK31 signal. This could be used for...
The model 4017 integrated circuit is a CMOS counter with ten output terminals. One of these ten...
When adding an alternating current signal to the capacitor, the wave position (the phase) of the...
