Octoglow VFD Geiger counter and magic eye Słomkowski's technical musings
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.
Magic eye circuits for 6E5 Google Groups
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.
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 tuning indicator as a VU meter BOGIN, JR.
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 Tube Audio Spectrum Analyzer Dr. Scott M. Baker
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,.

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 Tube Wavemeter
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.
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.
Magic Eye Emulation with Arduino Electroagenda
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 Red circuits blueprint r/factorio
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 Tube interfacing with a Raspberry Pi Dr. Scott M. Baker
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.
How to Generate Your Own Magic Eye Stereograms Online
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 using 555 Timer 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).
