    Where are the puppets? ๐Ÿ™

    Did you ever test that solar charge controller to see if it is Pulse width modulation or not?

    I have that same USB charger in the acrylic case It works great. It has a blue LED light that is is kind of bright at night.

    I know this is a rather old video to comment on, but I just noticed something. Rather than waiting to open a bunch of posts all at the same time and wondering what is in them or taking a flashlight (torch) to try and figure it out try this. Just film them as they come in the mail. Then you can just take the different clips add them together for your post bag video, and you might find it saves you a lot of time doing post bag videos as well as the frustration of hanging on to them unopened.

    Thank You for saying that; "My Computer is Running Slow". I thought it was mine!
    I know, we all know, that you know, how to fix that. Me, not so much. Love Your Videos, Julian!!
    I am learning exponentially. And I am 56.

    Had to laugh on that OLED that said it was white but turned out blue. I received one like that a few years back, and when I commented to the seller, they said they didn't even stock the blue OLED's and promptly refunded my purchase! Things sure do get interesting when dealing with those in China who have a very limited vocabulary. The last week, I got in some MC102 JFET's that were, in fact some N-channel BJT according to my tester and in now way behaved as a JFET which I use to build ghost detector toys for my niece who is into that sort of thing. They at first urged me to wait another week for the package to arrive, and when I asked them to find someone who spoke English to read my complaint, they offered to resend, or refund. I replied that if they could assure me getting the proper product, I would take a resend, however if not then a refund. I received my refund today. The reason I had ordered them from that outfit was that they were selling them for 20 for 8 bucks, where everyone else was selling them for a buck or more per transistor. So I took the refund and ordered 10 Motorola brand to see if they are better copies then the Fairchild fakes that everyone else seems to be peddling on Ebay right now. Sad to, as those little Jfets are great fun to play around with, they are so very sensitive to EMF.

    In case you haven't figured out why a red power button is there, it is so you can turn on your load in most cases. Or turn it off overriding the onboard controller.

    I'm sure I'm not the first to ask, but why on earth did you not get that speck out from under the screen? It was right there. But you left it.

    Arrrrghhhhh….. ๐Ÿ˜‰

  9. Avataaar/Circle Created with python_avatars nightmare in action says:

    that charge controller is 11 dollars wow

  10. Avataaar/Circle Created with python_avatars Raymond Heath says:

    I'd be interested in the ideal diode video and application. Thanks for great vids!

    no what are you doing? don't turn it on… take it apart!
