This self-contained lamp works like a charm — set it right side up to turn the light on, flip it upside down to turn it off again. It’s called the draailampje — that’s Dutch for “flip light.” Making a flip light is easy and fun — great for nontechnical people or first-time solderers, it makes for a perfect workshop or classroom activity. The project introduces a clever way to use a tilt sensor.
