Markus Gritsch build another bedside table alarm clock, the schematic and source code is available here:

recently some vintage bubble displays popped up at various places [1][2], so I felt the urge to build another bedside table alarm clock, this time a really tiny one, roughly the size of an AAA battery.

Check out the video after the break.

    Nice project.

    I have the same MCU (msp430g2452), same bubble display x 2, lot more buttons…. gives you a calculator.

    There is no write-up yet.

    it’s amazing to use one of the low energy consumption microcontrollers on earth with one of the more energy hungry displays :) it’s a pitty we can’t find such nice extra-small displays made with new low energy and high luminosity LEDs.

    cool project :)

    A-ha! I’ve got a similar 9-digit bubble display lying around (for a calculator, I suppose). Thought of hooking it up to an atMega or atTiny, but couldn’t think what for. Maybe I’ll just make a dual time zone clock, or time+alarm display. Need to have a look at the tech specs of your clock chip…

    Thanks for sharing your ideas!

  5. What’s the power source? Is it only 1.5V?
