Video: We talk about all kinds of electronics projects and name drop a variety of hand tools. But if you've never known exactly what tools you need or how to use them, Adafruit walks you through everything you need to know. The video runs through everything from flush diagonal cutters to tweezers. It's a great collection of not just the tools that are useful to keep around, but when and why you'd actually use them. If you enjoy messing around with electronics but haven't gotten around to buying dedicated tools, this video should cover everything you'll need.
