Book excerpt: What should an electronics hackerspace look like? Is it in your bedroom, garage, a classroom, or even a suitcase? And where do you start? What parts are essential, and which are just nice to have? And how do you organize it all? Dale Wheat, the author of Arduino Internals, will show you how to build your own electronics lab complete with tools, parts, and power sources. You'll learn how to create a portable lab, a small lab to save space, and even a lab for small groups and classrooms. You'll learn which parts and tools are indispensable no matter what type projects you're working on: which soldering irons are best, which tools, cables, and testing equipment you'll need. You'll also learn about different chips, boards, sensors, power sources, and which ones you'll want to keep on hand. Finally, you'll learn how to assemble everything for the type of lab best suited to your needs. If you need to carry everything to your local makerspace, you can build the Portable Lab. If you plan to tinker at home or in the garage, there is the Corner Lab. If you're going to run your own local makerspace or you need to set up a lab to teach others, there is the Small-Group Lab. No matter what your gadgeteering needs may be, Building Your Own Electronics Lab will show you exactly how to put it all together so you have what you need to get started.
