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.

Looking for a tiny PC that still has space for a gaming-quality video card? SFF PC Cases is a remarkably detailed spreadsheet listing dozens of models, complete with cost, dimensions, volume and even important build tips. The very smallest are not practical for powerful builds, but the critical “Maximum GPU length” field is right there […]
Benji Edwards’s guide to preserving vintage electronics is a fascinating look into all the ways that even solid-state gear can go off in long-term storage: a lot of stuff (batteries, capacitors and even rubber) can leak viscous, electronics-destroying liquids; plastics break down in UV light; mold and corrosion eat your gear from within; spiders, crickets […]

Toaster ovens are the perfect appliance for small things like toasted sandwiches and roasted garlic (try it!), but anything more involved usually requires a full-sized conventional oven.However, despite its small size, the Wolfgang Puck Pressure Oven can handle anything from baked pastries to broiled meats. This kitchen appliance has a minimal countertop footprint, and cooks […]
