Throwing in the towel | HLH

Last night I had strong hopes I would be recording my first gameplay video before going to bed. However, that did not happen.

 

As of this writing, the screen is working. Most of the buttons work. Except, when controlled by the Pi. When the Teensy and Pi are connected, it appears to create a short circuit. The troubling aspect is that when the Teensy is connected to my computer, no issue there. At least I have a Wii-U style controller for OpenEmu now. image

 

So the problem is with the Teensy, the Pi, or my wiring. I suspected the wiring first but cannot find an obvious fault. After that, I programmed a new Teensy but did not connect any wires. I get the same behavior by just connecting to the Pi’s USB, which is why I suspect the Pi. Perhaps I damaged the USB controller when de-populating the USB ports. When the kernel driver enables the USB controller, I see the 5 volt rail dip, the under voltage icon comes on (when the screen is connected), and sometimes the Pi reboots. If it makes it to EmulationStation, I can SSH in and see dmesg complaining about overcurrent.

 

Regardless, I have yet to start editing my video. Even if I could find and repair the fault in the next hour, I would not have time to finish a suitable video by the morning deadline.

 

I have never captured so much footage while working on a project. Right now my capture folder is sitting at 128 GB (interesting number) with more from yesterday’s SD Cards waiting for transfer.

 

So that what I captured does not go to waste, my goal is to re-work the project and produce an AddOhms video out of it.

 

Best of luck to everyone else. I look forward to watching your build videos and seeing who becomes the next Ben Heck.

  • James, Please do not drop from the Hack Like Heck competition.  You were one of my personal favorites and I would suspect one of the front runners for the gig.  Although it sounds like you will not complete the build by the deadline, the path you took to get the stage you are with your build should be most important part.  I believe Heck had some builds he had to set aside and readdressed them at a later point in time.

     

    One thing with the Pi, you really want to have a power supply that is capable of 3A or more especially if you are using a screen. Also, I hope you are not connecting the Arduino board directly to the Pi. There might be a mismatch between the GPIO pin voltage levels, so you would want to put either a level shifter between the Pi and the Arduino board or some sort of transistor driver circuit.  And, I tend to use a separate voltage supplies if I have a separate board in the mix and not power the secondary board from the Pi.  This way if there is a short somewhere in the mix, it would be easier to isolate. 

     

    Good luck and I really hope you with draw your towel and stay in the running.

     

    Cheers,

     

    Jon

    Thank you for the encouraging words Jon. The video is due in the morning. Since I did not achieve the primary requirement, a working build, I cannot participate.

     

    As I said above, I plan to recover the project in the future. Now that I have this one built, I see a number of places I could improve it.

     

    Cheers and thanks again.

    James, I don't have a working build yet either but I am hoping to still submit something. You are clearly a strong contender, please edit and post something!

     

    I know there is less than 12 hours to go, but I really hope to see you at the finish line.

    Thanks Ben.

     

    I thought about turning the video into “what went wrong.“ I even had ideas on how to do a “in part 2...”

     

    However.

     

    My interpretation of the contest was to create a working build. I was not able to do so in the time allotted.

     

    For that reason, I don’t feel right submitting a video. I understand if others are in the same boat and post what they can. I look forward to watching those as much as the finished builds.

     

    But for me, if I go that route, I would prefer to take the time to properly edit it. And, hopefully, include a positive outcome.

     

    Good luck Ben. Looking forward to seeing what you post.

    Fair call, and a lot of respect to you. I imagine as you already have a channel, it would be harder to publish something that you aren't 100% happy with image

     

    My interpretation is the same as well - but it's looking like quite a few contestants aren't finishing it 100% in time. It shall be interesting to see how that affects the results.

     

    I will definitely be styling mine as a "Part 1" video, assuming I can get something ready. It's the only way I can make it work as is. To be fair, Heck's original build was over two parts as well..

     

    Look forward to seeing your future content as well!
