If the input is coming from, say, a Function Generator`s typical output clipleads, then the `black` lead or `-` or `ground` is connected to the circuit`s ground. From the Pin 3 of a 555 timer. ditto, the timer`s ground must be common with the circuit`s ground. This forms a current path. If the ground reference leads of some other, line-connected instrument like an unisolated oscilloscope

is connected elsewhere in the circuit. now you have a ground-loop that might also carry power into the circuit from the FG or even from the mains. It looks like Mr. Clean has disconnected merely the positive pole of the battery alone, from the video, and that the negative battery pole remains attached to the circuit. Does the schematic ground indicate an Earth ground as well Is it plausible that ground currents may account for the effect Irregardless, this has to be the most exciting video of all time. From what I understand the ‰ 1kHz waveform comes from that 555 astable multivibrator and the LM393 comparator that is powered by the device itself. See the updated diagram in my 1st post. the inverter battery (commercial inverter) was grounded and when I moved it away from the battery my circuit was attached to the effect faded with distance. At about 4:30 in the video I disconnect the input power to the circuit and the noise continues, enough to light an LED. I think it had something to do with the old scope as well. I have a new one now. Anyway it wasn`t free energy or zipon`s. The voltage was about 13. 5 volts. When I shot the video I was still investigating it. I lit the LED with it later then discovered the battery thing after that. It was strange but that is why the clever guys like Tinsel Koala and the likes are here to help work through these things. I had to work it out for myself. But my first impression was...
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.....
