Over at Make: Online, the amazing Collin Cunningham has a new video to teach you practical electronics. This time, it's about perfboard prototyping and he shows you how to make a "rather unusual guitar effect."
When you think "DIY electronics," one of the first images that likely comes to mind is of parts and wire soldered to a standard piece of perforated circuit board — and that makes sense. Perfboard is widely used because it's so versatile. Essentially, it's just a grid of potential solder-point connections. You can trim it down to just the size you need, or leave extra space for future enhancements, or revisions, if need be.
