FFcossag works at an electronics repair company. In came one of these Cheap Chinese LCD Projectors, based on the dangerous mains input and build quality it was not worth repairing. Looks like it was just thrown together with a make it work attitude and no quality or longevity in mind. Once inside the system you can see the main AC connector is hot glued in place! There are also many
Brian Dipert has taken a look Inside the Amazon Dash Button. If you haven’t seen these before it is a little IOT device that is connected to your Amazon account and will order you some new products with the touch of a button. The design is battery operated and is small enough to be stuck where it could be pressed as soon as you realize you are out of something.
Mike has purchased a huge piece of electro-mechanical gear. Looks like this Laser Scanning Spectral Microscope would have cost the same as a small house at one time. Interesting to see how much in in this box of goodies. In the first video Mike goes over the internals of the system, in the 2nd video he gets the argon laser to fire! It takes a killowatt of power
Mike has taken apart a GFI Circuit Breaker and tested it to destruction. These devices are great to make electricity safer when used in dangerous environments such as beside water sources. They measure leakage current and trip when there is too much running from your hair dryer that accidentally fell into your tub full of water. “A GFCI works by measuring the current leaving one side of a
AvE got his hands on an Emergency Personal Locator Beacon. This is one of the few things made in Canada! Looks like no expense was spared in the build. The lithium batteries are still operational even though they were dated to expire 16 years ago. I have never seen the tape measure like antenna. Without making an electrical connection is it doing anything? I was expecting to see a
John Ward does an Extreme Teardown of Dangerous Power Bar. It is very drawn out but demonstrates how electrical equipment as simple as a power bar should not be assumed to be safe. This power bar has a lot of bogus specs on the packaging and at a glance looks to be of ok quality. As you will see looks is all it has going for it. The rest
Bigclivedotcom takes a look at how a 11kV Lightning Arrester works. When high voltage lines take a lightening hit they attempt to short it to ground to prevent passing the huge spike in voltage on down the line. The technique used is similar to what is done in a power bar on a big scale. When a high enough voltage is present in the line side a stack
