The good folks at Evil Mad Scientist Labs have unveiled their fantastic HOWTO for recreating a 1958, oscilloscope-based proto-video-game called "Tennis for Two," created by a physicist named William Higinbotham "to improve what was an otherwise lackluster visitors' day at the lab."
Before we start, let's be clear that this is not a tutorial in how to build an oscilloscope. Tennis for Two is supposed to display on a 'scope, so beg, borrow, or buy one if you don't have one handy. Older low-end analog scopes like mine (a Hameg!) usually go for $50-$150, and if nothing else, you can always make a Scope Clock out of it later.
There are three parts to the electronics that we're building. First, there is the AVR microcontroller-- the brains of the outfit. The specific variety that we're using is the ATmega168, the same chip used in (for example) the Arduino platform. Secondly, there are two handheld controllers that connect to the ATmega168 microcontroller. Each handheld controller has a knob and a button. Third, there is the digital to analog converter that takes the output from the AVR and uses it to drive the scope.
I got one of those bug-zapping LED lightbulbs, in hopes of murdering the flies drifting into my office during the increasingly warm and muggy Pennsylvania summer. I got mine from Home Depot, but the bulbs at Lowes, Wal-Mart and Amazon are all obviously identical. There are two lights in each bulb: an ultraviolet one inside […]

The popular fitness and travel figure was well-known in France, with some 55,000 Facebook fans and 154,000 followers on Instagram. One […]
Even though credit cards now feature an EMV chip for securing transactions, they still have to include the magnetic strip for compatibility with older point of sale systems. Because of this, there’s no way for the chip’s new security capabilities to protect against card skimmers in the wild.How do you protect yourself from legacy-technology-induced fraud? […]
As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
