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 combines two LTC1043s with a based humidity transducer in a simple charge-pump based...
Amplifier A increases the microphone"s output to a usable level. The output signal is fed to op...
The two neon bulbs will light when more than 100 V is across the ringing circuit. The bulbs...
This circuit has proved to be an effective video buffer and will easily drive a 75- load to...
The losses in a bridge rectifier can easily become significant when low voltages are being...
This circuit is used to sense the insertion of a penny. Before the penny is inserted, current is...
This circuit was in EDN`s "design ideas" section in the March 5, 2007 issue. It`s a fairly simple...
As mentioned before, a reason to modulate a message signal is to match the communication`s...
The AD650 V/F/V (voltage-to-frequency or frequency-to-voltage converter) provides a combination...
After getting some Micro Scalextric for Christmas and shortly after acquiring a vast mount of...
This voltage controlled frequency divider circuit (see figure in text) produces pulses of lower...
And the general high-frequency circuits, in the microwave band, the use of microstrip circuits to...
BKQ series automatic parallel controllers are designed specifically for small hydropower...
