What’s the worst mistake/problem you’ve made during a project, and what did you learn from it? We are asking e14 in our Join, Share & Win Competition

E14Alice

Hello Everyone!

Hope you are all doing well. I’m excited to announce that this month's AskE14 question is: What is the worst mistake or problem you've encountered during a project, and what did you learn from it?

Sharing your experiences can help others identify similar challenges and understand how to overcome them. I hope this discussion will be beneficial for those who are just starting out on a project or feeling stuck with a problem.

Here's the question:

What’s the worst mistake/problem you’ve made during a project, and what did you learn from it?

  • My worst foul up in recent history was on the Shark Chase Tank robot building for the E14 Fun & Games competition. 

    The chase tank was to autonomously hunt down the radio controlled Rubber Duck with Hammer.  The chase system used a PixyCam to object detect the rubber duck ( by color blob)  and it's placement in the field of view for steering sent to the controller via SPI. 

    The original Pixycam 1.3 was used, I decided not to use an Arduino Uno  for the platform, rather use an Arduino Minima R4 to include some other features. The Arduino PixyCam SPI code was not compatible with Minima R4, so I reverted back to an Arduino Nano to save space and upgrade to screw terminals. 

    Altho I compared pinouts, specs, and pin checked the hookup a dozen times, when it came to final assembly , I plugged in the SPI ribbon backwards. 

    I said a sad sayonara to the PixyCam as that finally did it in. 

    What did I learn ? .....time to upgrade the whole platform from blob detection to closed loop object detection tracking and steering !  

    "Every bursted bubble has a glory!
    Each abysmal failure makes a point!
    Every glowing path that goes astray,
    Shows you how to find a better way.
    So every time you stumble never grumble.
    Next time you'll bumble even less!
    For up from the ashes, up from the ashes, grow the roses of success!
    Grow the roses! Grow the roses! Grow the roses of success!
    Oh yes!
    Grow the roses! Those rosy roses!
    From the ashes of disaster grow the roses of success! "
