https://stream.echo6.co/videos/watch/8f8a8c39-2516-4e36-a04b-4980d702c77c A non standard video. Just a ramble about stuff on my bench before I tidy it up. The rosin dissolved quickly in the bottle of flux. I'm suddenly realising that it's probably just a bottle of isopropanol with a small chunk or rosin dissolved in it. Now I'm tempted to see what effect different ratios of resin in isopropanol have. I was a bit reckless with plugging in that rope light without knowing the polarity. Some LEDs don't take reverse polarity at a high voltage very well. The correct approach would have been to examine the LEDs through the tubing and try to work out polarity that way. The PTC fuses are usually just intended for low voltage. You do get versions for mains voltage, but they often have peak current restrictions. The primary advantage of these devices is that if a fault occurs they will trip, but then reset when power is removed and they cool down. I have since built my custom audio lead and it works fine. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
