If you find yourself ignoring notifications and alarms about meetings, you might need something a little more in-your-face. Make offers just that, with a flashing alarm that's hard to ignore. The alarm here taps into Google Calendar for events. At 10 to five minutes before an appointment, the lights flash white. From five to two minutes it flashes yellow, then closer to that they start going crazy. Absurd? Sure, but if you can't seem to get to appointments on time, it's one way to help yourself out. You'll need a Raspberry Pi and a Pimoronia Unicorn Hat to do make this for yourself. Head over to Make for the full guide.
