Hi Folks,

Here is my second project using the Propeller. It is a Morse Code Clock/Lamp. I had a lot of fun putting this together and I learned a lot too. Source code and schematic attached.

    How do you sleep with that flashing light going off all the time? Just kidding!! That sounds like a really neat clock.

    My wife suggested mounting the light into a model ship... smilewinkgrin.gif

    Hey Beau,

    I wasn't envisioning a clock that was always on, but one that you pressed to check the time. The switch that came with the lamp is a toggle though, pressing it again does turn it off. I would have preferred an always open tact switch. It's just a novelty project to learn spin, I probably won't go through the effort to fix it [noparse]:)[/noparse]

    A model ship, what a great idea! I was thinking how awesome it would be to have a real ship lamp with a fresnel lens.

    Thanks!

    Very creative! Looking forward to seeing what you come up with next.

    Excellent project! Can't wait to see the time set buttons included. I might have to make one and put it next to my binary clock on my desk.
    Depending on how the switch in the lamp is made, you may be able to remove the latching spring to make it a momentary switch that just triggers the time display.

    @WBA - This build does have time set buttons, it is in the schematic. I did not demo them in the video, mostly because I was embarrassed I didn't want to show you'd have to press the button each time for hours and minutes, So... 59 = 59 clicks. [noparse]:)[/noparse]

    Thanks for your kind words!

    johnnycarlos,

    Ohhh!!! If you mount the light on a ship you need to do away with ALL of the set buttons, and just have a light receiver on it as well. You 'set' the time by sending it the time in morse code with an ordinary flashlight!! smilewinkgrin.gif

    @Beau - what a grand idea!

    This forum is the greatest.

    If the light is wired as a separate output and the switch is wired as a separate input...

    Then you can achieve a toggle effect by remembering the switch state the last time it changed.· Each time the switch changes state you can store that state and flash the time once.· Then wait for the switch to change states so you can repeat the process!

    Maybe you should contact Hack-a-Day. They always do write-ups on interesting clocks. I'm sure they will publish your project.

    Special thanks to Mikercontroller for submitting it to Hack A Day!

    Very inspiring, considering it's only my second attempt to build something with the Prop.

    I agree with Beau a Morse clock should only have one button, a proper Morse key.
    Perhaps audio output on the hour/half hour during the day time, like a good old chiming clock.
