Magic Eye Circuit Using 4049 IC
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 Tube Wavemeter
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.
Magic eye working circuit YouTube
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.

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.
Magic Eye tubes help/suggestions Meter Circuit for FUN
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]

Magic eye tuning indicator as a VU meter BOGIN, JR.
These are mostly miniature Cathode Ray Tubes (CRT) with an electrode (or several) to vary the size of a shadow according to signal level. One Magic Eye works in a similar way to a VFD (Vacuum Florescent Display), the DM70 / DM71. The DM160 and the similar Russian iv15 are not Magic Eyes, just VFD type indicators.
Magic Eye Emulation with Arduino Electroagenda
This circular, with a cover in center, recalls the appearance of an eye. The side of EM1 is found for the same reception conditions, four bright areas, like four-leaf clover, separated by four gray areas, the edges end up meeting to listen to a strong station .
Magic Eye Winker • The senseless circuit YouTube
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 Tube Audio Spectrum Analyzer Dr. Scott M. Baker
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.
How to Generate Your Own Magic Eye Stereograms Online
"Magic Eye" emulation project written and developed by Konstantin Dorohov (USA). The recorders and receivers of my youth used the now defunct tube level indicators or "magic eye" on 6E1P or 6E5C lamps. Now is the time for nostalgia for the "old days" and you can buy assembled indicators on aliexpress or amazon.
Magic Eye Tube interfacing with a Raspberry Pi Dr. Scott M. Baker
Fuzzy is sometimes associated with an increased AC content on the input grid (ie. AC plus DC content). Perhaps there is a loading aspect of the magic eye circuit on the signal level being sensed, or a change to the rectification/filter time response (due to on-voltage or series resistance or reverse leakage) - which is modified by the change in diode type.

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.
