When it comes to coffee, some people just like perfection. Most would agree that the best cup of coffee comes from home, after roasting your own green coffee beans. But not everybody has the time or money to have complete control over their coffee's flavor. Roasting via stovetop or oven produces mélange (not quite perfection), and home roasters can be pricey.
Whenever we make a homemade circuit, we use what are called through-hole components. Any components with long metal leads is a through-hole component. They are great for soldering to, but it's tough to fit enough through-hole resistors and capacitors into a smartphone. To get those last microns, we have surface-mount components for SMDs (surface-mount devices). These are all of those teeny, tiny things you see when you crack open your digital camera or laptop case.
I have an absolutely wonderful time making projects and writing articles for all of you mad scientists! Today, I will bring you behind the scenes for a look at the workbench, tools, and software that make the Mad Science World possible.
