The Evolution of Wireless Game Controllers

The story goes that Atari was developing a premium model of their popular home video game console, the Atari 2600, for the 1981 fiscal year. Internally known as the Stella RC, this model revision promised touch sensitive game selection toggles, LED indicators, and onboard storage for the controllers. The focus of the project, however, was the “RC” in Stella RC which stood for remote control. Atari engineers wanted to free players from the constraints of the wires that fettered them to their televisions.

Problem with the prototypes was that the RF transmitters in the controllers were powerful enough to send a signal over a 1000 ft. radius, and they interfered with a number of the remote garage door openers on the market. Not to mention that if there were another Stella RC console on the same channel in an apartment building, or simply across the street, you could be playing somebody else’s Pitfall run. The mounting tower of challenges to making a product that the FCC would stamp their approval on were too great. So Atari decided to abandon the pioneering Stella RC project. Physical proof of the first wireless game controllers would have been eliminated at that point if it were created by any other company… but prototypes mysteriously left the office in some peculiar ways.

“Atari had abandoned the project at the time…[an Atari engineer] thought it would be a great idea to give his girlfriend’s son a videogame system to play with…I can’t [comment] about the relationship itself or what happened after 1981, but that’s how this system left Atari…and why it still exists today.”

Joe Cody, Atari2600.com

Atari did eventually get around to releasing some wireless RF 2600 joysticks that the FCC would approve. A couple years after abandoning the Stella RC project they released the Atari 2600 Remote Control Joysticks at a $69.95 MSRP (roughly $180 adjusted for inflation). The gigantic price tag mixed with the video game market “dropping off the cliff” in 1983 saw few ever getting to know the bliss of wire-free video game action. It was obvious that RF game controllers were simply ahead of their time, but there had to be cheaper alternatives on the horizon.

Out of Sight, Out of Control with IR Schemes

Nintendo AVS 1985 Display

Video games were a dirty word in America in 1985. While games themselves were still happening on the microcomputer platforms, the home console business was virtually non-existent. Over in Japan, Nintendo was raking in money hand over fist selling video games on their Famicom console. They sought to replicate that success in North America by introducing a revised model of the Famicom, but it had to impress the tech journos that would be attending its reveal at the Consumer Electronics Show (CES).

The prototype system was called the Nintendo Advanced Video System (AVS). It would feature a keyboard, a cassette tape drive, and most importantly two wireless controllers. The controllers used infrared (IR) communication and the receiver was built-into the console deck itself. Each controller featured a square metallic directional pad and four action buttons that gave the impression of brushed aluminum. The advancement in video game controller technology was too good to be true though, because the entire system received a makeover before releasing as the Nintendo Entertainment System (NES) that Christmas. The NES lacked the keyboard, the tape drive, and the IR controllers and its change in materials hardly captured the high-end flash of the AVS. The removal of IR meant the device was cheaper to manufacture. A decision that ultimately helped the NES to become a breakout success that in turn brought back dedicated video game consoles single-handedly.

How the Xbox Was Hacked

The millennium: a term that few had any use for before 1999, yet seemingly overnight it was everywhere. The turning of the millenium permeated every facet of pop culture. Unconventional popstars like Moby supplied electronica to the mainstream airwaves while audiences contemplated whether computers were the true enemy after seeing The Matrix. We were torn between anxiety — the impending Y2K bug bringing the end of civilization that Prince prophesied — and anticipation: the forthcoming release of the PlayStation 2.

Sony was poised to take control of the videogame console market once again. They had already sold more units of the original PlayStation than all of their competition combined. Their heavy cloud of influence over gamers meant that the next generation of games wasn’t going to start in until the PS2 was on store shelves. On the tail of Sony announcing the technical specs on their machine, rumors of a new competitor entering the “console wars” began to spread. That new competitor was Microsoft, an American company playing in a Japanese company’s game.

History of White LEDs

Compared to incandescent lightbulbs, LEDs produce a lot more lumens per watt of input power — they’re more efficient at producing light.  Of course, that means that incandescent light bulbs are more efficient at producing heat, and as the days get shorter, and the nights get colder, somewhere, someone who took the leap to LED lighting has a furnace that’s working overtime. And that someone might also wonder how we got here: a world lit by esoteric inorganic semiconductors illuminating phosphors.

The fact that diodes emit light under certain conditions has been known for over 100 years; the first light-emitting diode was discovered at Marconi Labs in 1907 in a cat’s whisker detector, the first kind of diode. This discovery was simply a scientific curiosity until another discovery at Texas Instruments revealed infrared light emissions from a tunnel diode constructed from a gallium arsenide substrate. This infrared LED was then patented by TI, and a project began to manufacture these infrared light emitting diodes.

That Time Atari Cracked the Nintendo Entertainment System

It was darkest hour for the video game industry following the holiday shopping season of 1982. The torrent of third party developed titles had flooded the home video game console market to the point of saturation. It incited a price war amongst retailers where new releases were dropped to 85% off MSRP after less than a month on the shelves. Mountains of warehouse inventory went unsold leaving a company like Atari choosing to dump the merchandise into the Chihuahuan desert rather than face the looming tax bill. As a result, the whole home video game industry receded seemingly overnight.

One company single-handedly revived video games to mainstream prominence. That company was Nintendo. They’re ostensibly seen as the “savior” of the video games industry, despite the fact that microcomputer games were still thriving (history tends to be written by the victors). Nevertheless their Nintendo Entertainment System (NES) was an innovative console featuring games with scrolling screens, arcade-like sprites. But the tactic they used to avoid repeating the 1983 collapse was to tightly control their market using the Nintendo Seal of Quality.

From the third party developer perspective, Nintendo’s Seal of Quality represented more than just another logo to throw on the box art. It represented what you could and couldn’t do with your business. Those third party licensing agreements dictated the types of games that could be made, the way the games were manufactured, the schedule on which the games shipped to retail, and even the number of games your company could make. From the customer side of things that seal stood for confidence in the product, and Nintendo would go to great lengths to ensure it did just that.

This is the story of how an Atari subsidiary company cracked the hardware security of the original Nintendo and started putting it into their unofficial cartridges.

The Bells! The Bells! One Battery since 1840

It is good advice to change batteries in your fire alarms at least once a year. Even our low-power LCD calculators need new batteries from time to time. But at the University of Oxford, they have an electric bell that has been ringing essentially non-stop on one set of batteries for about 178 years! Is the energy crisis solved then? Perhaps not. The bells require a high voltage but very little current and the pair of batteries — piles in the parlance of 1840 — have kept the charge flowing for about 10 billion rings. As you can see in the video below, though, the ringing isn’t very vigorous.

How does it work? When you think of converting electrical power to mechanical motion you probably think of a motor, even though there are plenty of other transducers like speakers, muscle wires, and solenoids. Arguably the first device was electrostatic bells that were invented by a Scot named [Andrew Gordon] around 1742. [Ben Franklin] made them famous, though, so they are often called Franklin bells.

Remember When Blockbuster Video Tried Burning Game Cartridges On Demand?

By the onset of the 1990s one thing was clear, the future was digital. Analog format sales for music were down, CD sales were up; and it was evident, at least in the US, that people were bringing more computing devices into their homes. At the beginning of the decade, roughly 1 in 3 American households had a Nintendo Entertainment System in them, according to this Good Morning America segment.

With all those consoles out there, every shopping season became a contest of “who could wait in line the longest” to pickup the newest titles. This left last minute shoppers resorting to taking a rain check or return home empty handed. Things didn’t have to be this way. The digital world had emerged and physical media just needed to catch up. It would take an unlikely alliance of two disparate companies for others to open their minds.

Soldering Like It’s 205 BC

Did you ever stop to think how unlikely the discovery of soldering is? It’s hard to imagine what sequence of events led to it; after all, metals heated to just the right temperature while applying an alloy of lead and tin in the right proportions in the presence of a proper fluxing agent doesn’t seem like something that would happen by accident.

Luckily, [Chris] at Clickspring is currently in the business of recreating the tools and technologies that would have been used in ancient times, and he’s made a wonderful video on precision soft soldering the old-fashioned way. The video below is part of a side series he’s been working on while he builds a replica of the Antikythera mechanism, that curious analog astronomical computer of antiquity. Many parts in the mechanism were soldered, and [Chris] explores plausible methods using tools and materials known to have been available at the time the mechanism was constructed (reported by different historians as any time between 205 BC and 70 BC or so). His irons are forged copper blocks, his heat source is a charcoal fire, and his solder is a 60:40 mix of lead and tin, just as we use today. He vividly demonstrates how important both surface prep and flux are, and shows both active and passive fluxes. He settled on rosin for the final joints, which turned out silky smooth and perfect; we suspect it took quite a bit of practice to get the technique down, but as always, [Chris] makes it look easy.

If you’d like to dig a bit deeper into modern techniques, we’ve covered the physics of solder and fluxes in some depth. And if you need more of those sweet, sweet Clickspring videos, we’ve got you covered there as well.
