If you are too stupid to know what "commercially viable" means then don't bother leaving a comment about Thomas Edison.

Love this video! You take me back about 30 years blowing up LEDS. I love when things are explained simple, so everyone can understand. Thanks!

My first job after getting my BSEET degree from College was at the Trans-Lux Corporation, manufacturers of large scale LED displays. At the time, only yellow, green & red LEDs, mostly for the NYSE, AMEX, CBT & CME. I was the LED Specialist, responsible for equal radiation profile for all LEDs in a scrolling display.
One day, we got a sample, a Blue LED ($500) that was barely 20 Candellas. But it was a whole new ballgame. Engineers flocked around it like babies to a Christmas Tree. From that humble beginning, we were able to feed RGB Video to the new RGB LED displays and revoluionized the Full Spectrum Large LED display market! I was There! yo.

I'm really happy that you're back. You have a good way in explaining. I hope you're here to stay for a long time!

This series is a gem! I don’t know anything about electronics but my 10 yr old son is SUPER interested in it. Finding videos that explain the topic so clearly (and, honestly, entertainingly) that we both can stay engaged with, understand, and talk about these concepts was very challenging. So I’m very grateful that you took the considerable time and effort to create this series, and make the world a better place than you found it.

I love the new round of super-basic videos. They will be great for my classes with the younger students. I am looking forward to the next one.

Thank you!! I am learning so much about the basics in Electricity. I have been looking for basic teaching like this for weeks. I’m so glad I found your playlist full of knowledge. I love your videos, and they are so educational. Thank you for all you do!

Wow, hello again Afrotech. Still loving the old sites stuff. Thanks for staying online and making new stuff.

Man your channel is wonderful. As a software developer trying to go deeper into learning about the internet of things your content is just what I needed to not stay lost.

I've been playing with semiconductors for a long time now and have always enjoyed making circuits just for fun, your site has sparked new interest, thanks...

I've always loved LEDs, ever since I got my first electronics project kit from Radio Shack as a kid. I was fascinated by the soft pure red light they put out. That was back in the early to mid 80s, long before blue or white LEDs hit the market, or anything with a high intensity output.
Great video! I'm always looking forward to the next one. I used your laser tripwire project to make a circuit that will be used to open up a solenoid valve to release a jet of compressed air and scare birds away from making nests on my house. It's almost complete and needs a good box to put it into so I can mount it on the side of the house next spring.

I'm a visual learner...so the demonstrations are really helpful and make it easier for me to retain the information. Can't wait to view more videos

Brilliant, simple, easy, and clear instructions. Who could ask for anything better than this tutorial?

Afrotechmods is finally back🙌 Thank you😀

Once I was at a casual robotics workshop (making things move) and the LEDs supplied by the organisers were cheap chinese ones with inverted leads: shorter Anode, longer Cathode.
I've been using the death test to figure out max current for a while now, and my Fluke tells me the Vf when I test a diode.
Good to see more frequent videos from you again, by the way :)

Your tutorials are the best man I watched all of them, please post more, I already see that a lot of people like them too

I've been waiting for you to do more of this. Thank you so much, keep on keeping on!

You explain it so well for the layman. Awesome! I only wish I could explain it so simply and be interesting at the same time.
robertchanrussell
No way, new videos from WhatYouOughtToKnow and Afrotechmods in the same day?? Is this heaven??
MarkMythV
I like how you explain and illustrate the topics.
