    I AM LEGEND! As Paul has said many times, it helps to make and label a drawing of the screen and rectangle corners on paper. Thanks for another most-excellent lesson Paul!

    This is the best education channel ever. I am out of touch with technical for a long time and wanted to make a project about object detection. It was hard initially to go over pages of documentation on stack overflow and other community sites and I was stuck for two weeks to get the opencv installed properly.. You made it possible to understand the concepts and now I have progressed much more in my project. Thank you.

    Good morning Paul McWhorter. Some time ago I started a project to digitize 8mm home movies and in my search on TH-cam for suitable electronics I saw a video of you using a Raspberry Pi with the camera module. I followed and performed the lesson with interest and gradually got hungry for more, after a short search session I found all lessons on YT, downloaded them and now follow them 1 by 1 . I'm 82 years old and an electronics engineer of the old school so need a little more time to absorb it. I want to thank you very much for your clear and useful lessons best regards James . b.t.w. I hope you drink DeCaf !!!

    I started watching your channel in 2nd Year of my course, now I'm in the final year Electrical & Electronics Engineering and my thesis will be based on an Arduino Project. You are a blessing Sir😊

    Made a screen archery target, 5 rings. Made 3 items changeable, R,cColor,cThick. Identified as 1 to 5. As for HW, I fold easy. To much to remember, but will try to improve.

    I have solved it. I let the circle bouncing! I'm not sure if it's the best solution, but it works. I described 5 variables (Hcounter, Wcounter Hdirectin, Wdirection and speed). I wrote in the loop Hcounter=Hcounter+(Hdirection). And then I made 4 "if" statements
    1. if Hcounter>719
    Hdirection=speed 2. if Hcounter

    Caught you live near the end and just watched the beginning. Love all the work you put in this. I noticed you have two rColor parameter on lines 22 and 25 what makes your black rectangle yellow.

    • @keithlohmeyer

      Looks like Paul just assigned the variable a second time. The last assignment (0,255,255) is the one used and it creates yellow in the(B,G,R) scheme that open CV uses.

      That was a great twist. I'd say it should garner some extra credit for sure.

    Here's my solution to the assignment. I made a bouncing ball instead. Admittedly, I probably would not have solved this had I not taken some of your visual python classes. Your different tutorial series are really tying together nicely. I haven't finished the vpython yet, but now that I'm caught up on the pi lessons I might "bounce" over there and get caught up on those lessons. I also just started your artificial intelligence with the web cam. Hard to decide which one to go to next. All really good stuff.

      Hope you don't mind me saying, but you aren't actually bouncing off the edge - you're just going into reverse if you're going to go over the edge which isn't the same thing. (unless you're only going at a speed of 1)

    I heve a problem that my picamera's screen is upsidedown. And I try some solution on the internet but it didn't work. Liike add "camera_raspi_fliph=1"and "canera_raspi_filpv=1"in the config.txt. Whart should I do to slove the problem?

    … can you comment on the Chinese spy balloon over Montana?

    • @ctlancearrowlarson8237
      @ctlancearrowlarson8237 ปีที่แล้ว

      There's a Texas H.S. that is very knowledgeable in this area, especially high altitude balloons. I like the capture, possibility of the balloon. A Raspberry Pi maybe a stowaway, keep him safe!

      Sorry Paul for this reply. I was trying to be funny, but am not good at it. The subject matter is to serious to joke about. It's best if I limit my comments to your class material. It probably would be best to remove my reply, if possible. It's a joy to follow any of your lessons. So much fun!
