Transistor Game Quotes

Everywhere I went during those days, the streets were filled with talk of the Mets. It was one of those rare moments of unanimity when everyone was thinking about the same thing. People walked around with transistor radios tuned to the game, large crowds gathered in front of appliance store windows to watch the action on silent televisions, sudden cheers would erupt from corner bars, from apartment windows, from invisible rooftops. First it was Atlanta in the playoffs, and then it was Baltimore in the Series. Out of eight October games, the Mets lost only once, and when the adventure was over, New York held another ticker-tape parade, this one even surpassing the extravaganza that had been thrown for the astronauts two months earlier. More than five hundred tons of paper fell into the streets that day, a record that has not been match sense.

For many decades quantum theory was regarded primarily as a mathematical description of phenomenal accuracy and reliability, capable of explaining the shapes and behaviours of molecules, the workings of electronic transistors, the colours of nature and the laws of optics, and a whole lot else. It would be routinely described as ‘the theory of the atomic world’: an account of what the world is like at the tiniest scales we can access with microscopes. Talking about the interpretation of quantum mechanics was, on the other hand, a parlour game suitable only for grandees in the twilight of their career, or idle discussion over a beer. Or worse: only a few decades ago, professing a serious interest in the topic could be tantamount to career suicide for a young physicist. Only a handful of scientists and philosophers, idiosyncratically if not plain crankily, insisted on caring about the answer. Many researchers would shrug or roll their eyes when the ‘meaning’ of quantum mechanics came up; some still do. ‘Ah, nobody understands it anyway!

Virgil returned to the Operator’s Station and entered a single command. Its effect was to draw together the reins of the eighteen sham programs, to lift out, as it were, all those long machine code sections and interleave them into one huge powerful program that seemed to coalesce out of nowhere, having already penetrated the Worm’s locks and defenses. This monster program, then, had calmly proceeded to wipe out all administrative memory and all student and academic software, and then to restructure the Operator to suit Virgil’s purposes. It all went—payroll records, library overdues, video-game programs. From the computer’s point of view, American Megaversity ceased to exist in the time it took for a micro-transistor to flip from one state to the other.

The MIT Media Lab lists our device as the first of what would later be called wearable computers, namely, computers that are worn on the body as part of their function. In late 1961 I built the second wearable computer, a knockoff to predict the wheel of fortune or money wheel. As in the roulette computer, my device used the toe-operated switch for input, the speaker for output, and just a single unijunction transistor; it required only one person. Matchbox-sized, it worked well in the casinos, but the game had too little action to conceal the spectacular consequences of my late bets. Several times when I placed bets on 40:1 as the wheel was spinning, the croupier would give the wheel an extra push.

ADD A BUZZER TO YOUR GAME Congratulations: You’ve finished the last project in the book! Now, it’s up to you to decide what to make next. If you’re not sure where to start, why not add more circuits to your reaction game? The LED in the middle is where you want the light to stop, and I suggest adding a sound circuit to bring some excitement to hitting your target. To do this, you could use an active buzzer like the one in “Project #2: Intruder Alarm” on page 11, as shown in this partial circuit diagram. The darker part of this circuit shows new components you’d need in order to add a buzzer to the reaction game project. The lighter components are just a section of the original circuit diagram. Connect the positive leg of the middle LED through a 1 kΩ resistor to the base of an NPN transistor. Then connect the buzzer to the transistor’s collector. Connect the positive side of your battery to the other side of the buzzer, and connect the negative side of the battery to the transistor’s emitter. You should end up with a circuit that makes a little beep every time the light passes the middle LED. If you can stop the light on the middle LED, the buzzer should beep continuously to indicate that you’ve hit the main target. When you’ve customized the game to your liking, solder it onto a prototyping board. Maybe you’ll even want to place it in a nice box to hide the electronics and show only the buttons and LEDs.
