This really was a challenge to connect up! But now I know how to make a Motor Reversal Switch…Nightmare!

    Hi Harmon, Well done and keep up the great work….

  3. Michael Green says:

    A pretty tricky device, Harmon. Sometimes the harder the things that you try are the most rewarding and can lead you to other ideas about how to manage the switching. Am awarding another 5 stars because of the degree of difficulty and patience exercised. In a few years I wouldn’t be surprised to find you in engineering. Good work and God bless.

    I finally got to watch this Harmon. simply Amazing!!! Keep up the great work! I’m glad you understand what you’re doing & most of all, enjoying it.

  5. Harmon you seem to have a very good grasp on it. 🙂

    Harmon,
    I admire your passion to do something you obviously love. Physics isn’t seen to be an easy field in society so you have done very well at your age to be able to understand some aspects of it. Congradulations

    Hi Harmon,
    Great experiment. It was easy to understand

  18. What a good idea! Your invention would open and close doors automatically. It can also be use with boats to make a reverse run. Keep it up my boy. We need minds like yours so that this world will have easier way of living.

  19. Judy Seeto says:

    Hi Harmon….
    Well done….When I was your age, I was busy just playing. You have surpassed my knowledge at your age. Keep up the good work and next time we view your videos, instead of calling you Master Harmon, it will be Professor Harmon.

    Once again, well done on what you have achieved so far.

    Cheers

    Judy

    Harmon, well done on your experiment. Congratulations, you are turning into a very inteligent young man.

  27. Aleck Hoffman says:

    Hi Harmon,
    Well done I have tried this once before and actually gave up and done something else, it seems you have the feel for electrics

    Regards
    Aleck

  28. Jade Schafer says:

    Awesome work Harmon!!! A lot of thought and work went into your experiment. WELL DONE!

  29. Neta Shea says:

    That experiment looked complicated. Good work Harmon.

    That’s great Harmon.. You could grow up to be an electrical whiz one day

  31. Garth Wong says:

    How cool is that! I could never understand physics so I admire your understanding of the science behind electrical circuits!

    Congraulation Harmon, don’t know how you made it, but it worked. This is only the tip of the iceberg for you Harmon, keep working towards your dream and you will succeed. If you love science like you obviously do, then in the future you may make a big differnce to this planet.
    Cheers
