A new project has been made available; Temperature Controller. This is (as the imaginative title suggests) a relatively simple temperature controller for single-ended loads. This can be used to control heaters, fans, refrigerators/freezers, and so on. See the project page for more details!
Furthermore, it seems there wasn't a front page post for a project previously added; Waveplayer. This can be used as a general-purpose standalone audio playback board that supports playback of moderately high sample-rate/bit-depth wave files. See the relevant project page for detailed information!
