SystemSix: a modern homage to Macintosh computers

Reading Time: 3 minutes Dubbed a “desk accessory”, it displays the local weather, a calendar, the current phase of the moon, and even the bin collection day, among other things. But what makes it extra-special is that it’s housed on a stylish laser-cut piece of acrylic, bent to allow it to stand. It’s an impressive piece of work. Introducing…… SystemSix: a modern homage to Macintosh computers weiterlesen

Over-engineered robotic scalp scratcher knows all the moves

Reading Time: 2 minutes Arduino Team — August 5th, 2022 Those cheap wire-arm head massagers are great at giving your scalp a nice, relaxing rub. But they’re handheld implements that force the user to either manipulate the massager themselves or talk a partner into performing the task. David McDaid decided that the experience would be much more pleasant if…… Over-engineered robotic scalp scratcher knows all the moves weiterlesen

LEGO-firing turret targets tender tootsies

Reading Time: 2 minutes Arduino Team — August 4th, 2022 Stepping on LEGO bricks is a meme for a reason: it really @#$%&! hurts.
