Dandelion coffee In 1919, dandelion root was noted as a source of cheap 'coffee'. It has also been part of edible plant classes dating back at least to the 1970s. Harvesting dandelion roots requires differentiating 'true' dandelions ("Taraxacum" spp.) from other yellow daisy-like flowers such as catsear and hawksbeard. True dandelions have a ground-level rosette of deep-toothed leaves and hollow straw-like stems. Large plants that are 3–4 years old, with taproots approximately 0.5 inch (13 mm) in diameter, are harvested for dandelion coffee. These taproots are similar in appearance to pale carrots. After harvesting, the dandelion roots are dried, chopped, and roasted.
Dandelion chip Dandelion chip A dandelion chip is an electronic device, installed on the bayonet mount of a non-electronic camera lens or adapter, which enables electronic interoperation with certain cameras. The device consists of an integrated circuit connected to a series of exposed electrical contacts, in a curved package which matches the lens mount. It is designed to be affixed in a particular position on the mount, in order to mate with matching contacts on the camera body. The contacts on both sides of the mount are commonly known as "CPU contacts." Camera functions enabled by the chip may include exposure metering,
