How The 555 Timer Works (Astable Configuration)
In this video I go over the 555 Timer in the Astable Configuration. The 555 is one of the most popular Integrated Circuits in Electronics because the number of application in many types of circuits. Here we are going to learn about the basic configuration of a Timer as well as how to calculate the Period, frequency and duty cycle. In the second part we go more indepth into the inner workings of the 555 Timer

Thank you!
I recently did this but it's causing my host computer to blue screen every time i run the vm, if anyone knows a solution please let me know
how can i isolate the network?
it is call the BRICS
@@Roottech25 wdym?
not working
how enable connect to as for map a unit with another user, example my map unit direction is a linux server
tried this on a asahi unbuntu and broke a lot of stuff. If you are using asahi ubuntu on a mac M2 M1, don't install kali stuff on this for now.
That is an NPN transistor, so the LED would turn on if the switch is turned on the base of the transistor
You have an error: Vcc * (R2/(R1+R2)) = 9 * (33 /(68+33)) = 2.94 Volt, NOT 2.6 Volt
@@sm6fie I mentioned that at the beginning of the video. That I mad3 it 2.6 intentionally.
While calculating the Voltage at the base you ignored the base current, and later you tried to determine the base current using the incorrect base voltage. At the end the base current can be neglected anyway .however not the right Methode to determine the beta
@@semperagilis you don't have the beta of the transistor... how are you going to get collector current.
this got it working for me..Great video, well done!!
Clickbait! Ads and no LEDs at all! Reported.
Collector current= (Emmiter-base) current.. =(2mA-16uA)... but 16uA is negligible when compared to 2mA.😅
thank you, you're better than my professor
Thanks
It's basically making a new instance for loads with resistance which doesn't work in some cases with voltage dividers (resistors) changing the numbers without it.
It works like a breeze! Thanks :D
I do not have "Virtual Machine Connect" where did that come from? Is this something I need to download ?
Thanks you
Hi!, this works in Pop OS? Thanks man
I'm running Ubuntu 20.04 and I get this error when trying to run the installation script: "Ubuntu 22.04 or higher is required to use this installer." Do you know if/how I can get around this without changing the OS?
When I type sudo alsamixer it says host is down
How a Current Regulator Works please ?
You got the secondary voltage with the math. But it would have been easier to calculate it on the secondary side rather than the primary side. You have 220vrms primary with a 22:1 ratio (=220/22) = 10vrms secondary. So then, 10v times 1.414 = 14.14 v. peek on the secondary. Simple right? No need for math cause you can do it in your head.🙂
Great video! The only issue I see is your going to have a hard time drawing 1 amp through the load coming from the secondary of the transformer that is 12v @ .5 amps. The transformer's secondary winding will short out fast and the primary will follow suit, producing a short across your 220v AC mains! Better put a fuse in circuit on the primary side of the transformer to protect your wall outlet from starting a house fire! :) Seriously though, I did love the video! Great job teaching the math involved! :)
Legend.
The world's best teacher thanks sir
I misheard trans sister instead of transistor :)

The thumbnail looks just like Forrest M. Mims III discussion on page 118 of volume IV of Forrest M. Mims III book Electronic formulas symbols & circuits...! Of course you can't go wrong using Forrest's work, he has worked so hard on his books teaching electronics from start to finish...All his books use the graphing paper and the fonts are distinctly his hand writing.
that was one of the first book I read after I graduated from Telecom school back in Cuba in 1990. Actually, I have read other books but yes the image was taken from there. I guess I need to find time to make images lol... I try better, my english is also not very good looking but improving. thanks for your comments
Thank you!🙂
I have had the hardest time setting CUPS up on my home server. This finally made it work. Thank you so much!
when you are doing this, change the default number to whatever the number would be in the boot menu, the first option is 0, then 1. in my boot menu windows was the third so i changed the default number to 2 and it started perfect
How can I contact you?
How did you find the Kali key? I can’t find it anywhere. Someone please help.
what is vm connect? as you double click on vm, it's not opening with me
how about "your connection isn't private" https certificate?
there is NO 'SETTINGS' in FILE menu!!!!
Thank you Sir for the rich teaching. And please Sir I have this board hp laptop dv7000 it's generating 5v and 3v on its coil (Inductor) but not powering on and I've tried programming the bios chip still not turning on. Please Sir what step should take to get it fixed?
GREAT explaination, great tutorial, covered slmost everything
Excellent appreciate your struggle!
Thanks for
This is a great video. Thank you. I had a unique different audio problem. For some reason when I opened the "Sound" app from settings my device was changed to Digital Output. I switched it to the Line Out Built-in Audio device and my sound returned.
i have one doubt. Can we add Linux Users to Server 2016 AD? its possible?
Thx but not working anymore
At 2:28 - that's not a backslash - en.wikipedia.org/wiki/Backslash
it helped, thnx
nice, but how can you stop it and restart the effect?
Ctrl+C
thank you buddy you just do my work easy
thanks for sharing. Mine prompted me to select the edition of the os (home/pro/education etc) which i am installing .I also had this errorr: "could not create partition on disk 0 what could be the issue?
I thought I could do it without watching your video, but nah, ai can't replace you bro
