Another LED type that I learned about a few weeks ago is called an addressable LED. It’s a bit beyond this video, but worth noting for the advanced users as it allows multiple LEDs to be controlled at different colors each using only one signal pin on a microcontroller. It is a LED with an internal microcontroller that can be gotten as either RGB or RGBW and is controlled by a high low signal. The LEDs are chained in sequential order by their signal pins. To control them, a signal is sent containing the information for all the LEDs in the chain. The first LED removes its instructions and then sends the remaining signal to the next LED. These LEDs can be bought individually or in LED strips.

LED's are basically amazing stuff. When I was little I only saw LED in red or green, and they were very dim, only useful for indicator lights on various machines. Then someone invented blue LED and now LED has basically replaced light bulbs.

Excellent video. Being an old TV, RADIO. Repairman in the 70’s I have a steep learning curve ahead of me. MOSFET was the cutting edge of the cutting edge when I started Medical School. Now at age 70, I am still seeing patients but am getting back into electronics. In my life as a physician, I met many veterans from WW2 and into the early 1950’s. Learned a lot once their NDA’s expired. Amazing what they were able to do with vacuum tubes! Now, something I would appreciate your expert opinion. I learned physics in undergrad, Kozarev’s theories, which he proved to a certain pin extent, were fully validated in the Mid to late 80’s and 90’s. The physics of his Spiral mirror are amazing but well beyond my math level. I found out last year of a recent experiment in the last 10 years, they were able to SEE the Pleiades where they currently are both with light telescope and radio-telescope when using the Kosarev spiral mirror in conjunction. The Pleiades are 1200 light years away. This would indicate that Kozarev’s mirror is able to receive tachyons or other similar particles. There is a documentary on KZfaq about the experiments that were tried in an area of low magnetic field near the North pole. Please let me know what your thoughts are on this scientifically proven but quire mysterious device. My name is Sergio AKA Dr. T🖖🏼

For a long time, LEDs could only be produced in the colors infrared, red, orange, yellow and green. It was not until 1990 that blue LEDs and thus also white LEDs could be developed. I know that back then cars used blue bulbs instead of LEDs for high beam indicators.

You should do a video on "Toasters explained - How toasters work...and why you shouldn't put silverware into the slots" from an electrical engineering perspective. The electrical engineering behind the average toaster is both fascinating and horrifying. The toaster is probably the single most dangerous standalone appliance in the average home. While microwave transformers are far more dangerous/lethal and the large capacitors found in A/C units can also deliver a lethal charge, you have to disassemble those appliances to enter danger territory. The toaster, on the other hand, can deliver a lethal charge without any disassembly and can also short itself out and even cause electrical fires. The toaster also has plenty to cover on the electrical engineering front despite just being a bunch of metal and wires.

I was pleased that your animation showed the correct electron flow direction from negative to positive. In electronics college our instructor demonstrated this with a piece of graphite and a piece of paper. With high DC voltage and the negative connected to the graphite the arc produced carried graphite particles to the paper as the arc continued through the paper to the positive electrode on the other side.

@frommarkham424 Жыл бұрын

You are correct in that the electrons originate from the negative terminal and go towards the positive terminal But the electric field originates at the positive terminal and ends at the negative terminal. The direction of the electric field is opposite to the direction of the electron flow.

@waterfaII 6 ай бұрын

Humans can see infrared light under certain conditions. Infrared light has longer wavelengths and lower energy than visible light. The human eye is made of water, which absorbs infrared light at wavelengths just slightly longer than the deepest red color that humans can perceive. However, if infrared light is bright enough, and of short enough wavelength, then humans can perceive it as red. edit: that was bard, I am no that smart

As a person born with astigmatism and nystagmus, I despise LED's nowadays. They are practically blinding, burn images in my eyesight that lingers for a long time, and have horribly opaque halos around their source, which makes it impossible to see. One could say "lol don't look at them", which is nearly impossible since nearly everything have them installed anymore, so much of which don't have a method of diffusing or masking/shading the diodes. This includes streetlights, billboard displays, headlights/taillights, screens, stoplights, ceiling light strips, industrial work lights, spot lights, etc. How can one avoid looking at them when they're everywhere?
