Video game logic made from analog circuit. Activate power at the right time in to hit your opponent and win.

Generating interesting imagery on an analog oscilloscope is a fun activity enjoyed by many, with an excellent demonstration by [Henry Segerman] provided in a recent video which covers [Matthias Goerner]’s demonstration. Using the electron beam, shapes can be drawn onto the phosphor of the oscilloscope’s CRT — all without touching any digital circuitry. At the core are analog components like an operational amplifier integrator, multipliers and other elements.

This (unfortunately) silent video was made by Tek employees who wanted to see what would happen in the worst case of a CRT implosion. These tests are not standard testing conducted by Tektronix and do not meet any applicable regulations including U.L. standards. All liabilities are disclaimed.

Note that the tests with CRT’s in shields almost entirely contain the energy of the implosion. In the instruments the Museum has received with broken CRT’s, the CRT breaks at the neck and releases the vacuum without further internal damage; no “implosion” as such occurs.

We have made a rough estimation that the energy released by an implosion is between 200 and 300 joules, or watt-seconds. But since the energy is released in a few milliseconds, the peak power could be as high as 50,000 joules per second, or 50,000 watts.
