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.
Lured by the internet’s pervasive insistence that it represents a superior, more comfortable typing experience, I recently went back to an old-timey mechanical keyboard. This was a mistake. I am now a hamfisted ASCII jazz disaster.
SpareOne Emergency Phone is a basic cellphone powered by AA batteries. This gives it a relatively short time on a charge, but means that it will have a charge after being stuffed in a drawer or glove box for months. I came across this during my search for the perfect basic phone, but be warned: […]
Low-cost carrier Easyjet has prototyped “Sneakairs,” a pair of shoes that have small vibrating motors and Bluetooth links; they work in concert with your mobile phone’s mapping app, buzzing left or right when it’s time to turn, and twice if you’ve gone the wrong way.
