Open Source Smart Smoker Brings The Heat (Slowly)
https://hackaday.com/2019/09/04/open-source-smart-smoker-brings-the-heat-slowly/
Conceptually, cooking on a grill is simple enough: just crank up the flames and leave the food on long enough for it to cook through, but not so long that it turns into an inedible ember. But when smoking, the goal is actually to prevent flames entirely; the food is …read more (https://hackaday.com/2019/09/04/open-source-smart-smoker-brings-the-heat-slowly/)

Mechpen: SCARA Drawbot For The Big Picture
https://hackaday.com/2019/09/04/mechpen-scara-drawbot-for-the-big-picture/
It’s not uncommon to find us doodling on paper as an aid to thinking, for recreation, or simply because we’re bored. But, this kind of manual labor is so last century. It’s 2019, and we should have robots to fill our notebooks with cross-hatched illustrations.
