Octoglow VFD Geiger counter and magic eye Słomkowski's technical musings
Magic eye tube on battery power. A reader recently sent me an email asking me if a magic eye tube could be powered by a 6 or 9 volt battery. I thought about it for a while, trying to figure out the most practical way to obtain the high voltage needed for the target.. After assembling my prototype circuit, the magic eye tube ran successfully.

This makes the magic eye tube a perfect choice to display a one dimensional V-U characteristic of a given wave in real time. THE POWER SUPPLY CIRCUIT: The PSU circuit, basically employs a 555 timer to set a stable oscillation frequency for the MOSFET, which in turn uses the property of inductors, that whenever an abrupt change of current occurs, a voltage spike is induced on the output.

With the ghostly green glow of its circular face, magic eyes stood in for more expensive moving-coil meters for things like tuning indicators and VU meters. And while they may be getting hard to.

There are two main types of tuning indicator. One consists basically of a meter, the detection of whose needle indicates the accuracy of tuning. The other employs an electron-ray tube which presents a visible fluorescent display whose area varies according to the control voltage applied to it.
Magic eye working circuit YouTube
The operation of this circuit is quite straightforward and can be used with other tuning indicator tubes in general. There's an anode supply of 250 volts d.c., functioning also as a voltage source for the grid (current limited and stabilized to 24 volts, by means of a small Zener diode).
Magic eye tuning indicator as a VU meter BOGIN, JR.
A magic eye tube or tuning indicator, in technical literature called an electron-ray indicator tube, [1] is a vacuum tube which gives a visual indication of the amplitude of an electronic signal, such as an audio output, radio-frequency signal strength, or other functions. [1]

IC 4049 (Hex Inverter Buffer) IC 4049, also known as hex inverter buffer IC, is used for the conversion of high logic level to low. 4049 IC can handle two TTL loads as it has higher input supply voltage with a current rating of 1mA. The main application of IC 4049 is creating voltage multiplier circuit. It can also be used for square wave.

Magic Eye Tubes and Tuning Indicators Good eye tubes such as 6E5 and 6U5 are getting harder to find. Many of the old ones have lost most of their green glow. You can increase the green by a slight modification of the circuit. These tubes were originally specified for operation at about 250 volts.
Magic Eye Emulation with Arduino Electroagenda
A magic eye tube is an electronic vacuum tube that provides visual indication, usually in the form of green light, on an area called the target inside the tube. The target is partially illuminated with the exception of the shadow area, which varies in size and shape depending on the signal applied to the tube.

An anode held a coating that would glow when hit with electrons — usually green, but sometimes other colors. Later tubes would show a stripe going up and down the tube instead of a circle, but you.

Although the magic eye circuit is simple, this project requires connecting to a high-voltage current source within the chassis of an antique tube radio. For that reason, I consider it suitable only for advanced builders and radio restorers.
Magic eye tuning indicator as a VU meter BOGIN, JR.
The tester uses an eye tube (sometimes called a magic eye tube) as an indicator. A 40 MHz oscillator produces a signal that finds open and shorted capacitors. You can also measure resistance,.
How to Generate Your Own Magic Eye Stereograms Online
The magic eye circuit is based on NOT gate CD4049 IC. In this circuit, we are utilizing only 1 gate of IC. To understand the working you should know about the truth table of NOT gate which is: In NOT gate, we will get output as logic high when logic zero is provided and we will get logic zero when logic1 is provided in input.
