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 input stage is comprised of a both halves of a 6SL7 octal dual hi-mu triode in a differential...
The time circuit can provide a time delay of up to 20 minutes. The circuit is a standard...
While working on an Electricity/Electronics exhibit for the Museum of Science in Boston I...
This circuit runs a fast battery test without the need of power supply or expensive moving-coil...
We present a simple and high-throughput microfluidic system for diffusion-based monolayer yeast...
This project is based on integrated circuit from Holtek Semiconductor HT6221/HT6222. Similar...
This detector circuit is sensitive to low frequency electromagnetic radiation and will detect for...
If you ground the blue wire at the headlamp switch and the lights come on the switch is bad. I...
A tracking mount for trusty Minolta SRT-101. My untracked photos of Hyakutake had not done the...
This adaptor circuit is essentially a 100mA constant current source. It is applied across a...
This broadband AM receiver enables you to monitor` the shortwave radio band. The circuit has been...
555 IC using a delay circuit ter It is the transition from low to high delay circuit. Ie after...
AC negative feedback circuit is composed of R R and islands (Figure 1-30), since the C3 AC can be...
As shown, the circuit includes a clock pulse generator, and a pulse distribution circuit drives...
