Running your LED "neon" ornaments from USB - including a total screw-up

This video was a catalogue of disasters. I even said right at the beginning not to trust the red/black polarity marking in generic Chinese products. They literally use whatever colour of wire is available. That said, this is a great way of saving the ongoing cost and inconvenience of using standard or rechargeable batteries. It lets you choose either the batteries or a USB power source. You also have the option to change the LED strip to a colour of your choice, as it is widely available online. This strip is a 3V version. You also get direct 5V versions with a resistor per LED, and a 12V version too for handy off-grid illuminated ornaments. The diode I used was a 1N4007, which is a very standard 1A 1000V diode. It's a component I think should be in everyone's universal component kit. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- https://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty. #ElectronicsCreators
