panoramascope - an oscilloscope with mechanical X deflection

e panoramascope an oscilloscope with mechanical X deflection Obviously, it would be unwise to expect sensational technical data and precision from such an instrument. However, as illustrated in figure 1, the panoramascope is undoubtedly original and very easy to operate. When the device is switched on, the "drum" containing the row of LEDs will rotate directly in front of the observer. If a DC or AC signal is then connected to the Y input, the row of LEDs will light in sympathy with the signal, and an oscilloscopic image will be built up. This proves that a mechanical X deflec- tion can successfully be employed to display an alternating (or DC) signal on a "screen". In actual fact, it is an optical illusion. When light spots are rotated at a high speed our relatively slow optical sensors are no longer able to distinguish be- tween the sections of the picture. After reading the subheading, the serious minded electronics enthusiast may be excused for thinking that Elektor have taken...
