DIY Espresso
Free PDFs are available from Make Magazine that guide you through making your own coffee roaster, hydraulic coffee tamper, and more.
If you're absolutely, 100 percent serious about making your own espresso, you'll want to go beyond merely grinding boutique beans in the morning. You'll want to roast the beans, tamp the grounds with perfect pressure, and then make sure your espresso machine's at exactly the right temperature. Fortunately, Make Magazine has free PDFs for doing it yourself: DIY Coffee Roaster, DIY Espresso Tamper, DIY PID Temperature Control. [via Gimme Coffee]
