ChrisFix is this you lol. U r the truth my guy
I guess this is how car turn signals work? Thanks for the wonderful series. I had no clue about electronics but have been able to follow your tutorials and no longer be clueless
I read this in a textbook, never got it. With this man, i understood it! This man is so good at explaining things in an easy way
i know right
you are so good in explaining things. consequently ; no ad has been skipped. you helped me; I'll/we'll freaking help you.
please continue making such videos. kudos!
"Failing means you are learning"
I must be a genius by now.
Thank you for this series. I just watched them all and realized you have been recording these for years. You are doing a great job. Now following the series. Hope to see more updates weekly.
I recently found your channel and I have to say, I don't think there was a better time to become a fan! I love the weekly videos. I have caught up on both of your series and am always hungry for more. Keep up the awesome work!
Your videos are awesome! I'm seriously thinking of taking electronics on as a hobby!!
you're back!!! have you thought of doing a video on a voltage controlled oscillator? that'd be killer!
Thank you so much for making these tutorials. You explain things in a really clear to understand way. Ive learned so much in a short space of time. Looking forward to the rest of the series.
What do you mean "strange cuts"? that technique is awesome and really increases video quality
whoa!!!Really great contents. One of the best and most underestimated channel. I'm a fan now too!!!
i love you
continue making this awesome videos
Sir this series is helping alot.
Very much thankyou.
I Become your fan from INDIA🙏🙏
Your Tutorial are awesome🥰
wow my first VCO , thanks for the great tutorial series
What if you would add a potentiometer in series? Would you be able to adjust the oscillation and therefore the pitch coming out of the speaker?
yes you can
Please explain how to connect it in series ..between which two pins?
Very helpful, thanks!
Hi, I have a question. I understand why the capacitor is extending the time that the electromagnet in the relay stays on, but I don't know why it also extends the time the electromagnet stays off. Be cause in the demo, I can clearly hear that the clicking is very consistent.
I'm new, but i'll to explain with the best of my ability. You are correct the electromagnet stays off longer. but its soo minuscule that its unnoticeable to the human senses. considering electrons move at the speed of light (3 * 10^8 m/s) and the only resistance is that of a copper wire (1.72 x 10-8 Ω per metre). the time difference for it to charge can be calculated using t=rc. assuming that a capacitor has a capacitance of 1000µF. t = 1.72 x 10-8 Ω * 1000µF. therefore t = 1.72 x 10-11 seconds. This capacitor takes five time constants to fill, 1.72 x 10-11 x 5 = 8.6x10-11. it would take 8.6e-11 seconds for the battery to fill the capacitor. As I said, soo minuscule that your senses would never realise.
Because the power in the cap has to go somewhere, so it discharges itself and dumps its power into the electromagnet, therefore keeping the relay off after the power has been disconnected.
your doing a great job. I've learned a lot just by watching these! please keep these videos coming. id like to learn how to build this 8 bit computer along with coding/programming and much much more from there on. thanks man! (:
technically you could use this circuit and depending on the capacitor design a metronome for music
I'd imagine the frequency reference for the oscillation (capacitor and relay) would introduce plenty of rubato!
ChrisFix I know this is You Lol. Great teacher and keep making great vids
for anyone who's relay "isn't working", make sure your battery is strong enough to activate the coils. if you have a 12 volt relay, you need a minimum of around 9.6 volts.
awsome!!!!
but doesnt it more take time to charge the capacitor then to operate the coil?
Awesome!
How many volts battery you had used in this video?
Perfect tutorials
good teaching
I got a HK4100F and i sucessfully made it😊 thx a lot
took me more than an hour to figure it out how 4100f work
by rights, you should have a diode stunt the replay coil to protect the switch from arcing when the magnetic field collapses which induces a high current
From which terminal are the electrons actually flowing?
These videos are great! Smashed through all of them in the last week! Do you have any idea as to when you might be uploading the next one? Or perhaps some resources you would recommend for continued learning? Many thanks!
thanks for teaching us :)
I there was a super like button, I would smash it for this video.
You are amazing
It would have been fun to hear the speed with no capacitor at all. Even with the risk of damaging the relay. But you know, for science :-)
😂... You do it and comment..
Man you are great! Thank you!!!!
What's the point of the gray wire?
this is great

best video ever sooo cool !!!!!!!!!!!!!!
Can you do this with a five pin relay?
"Codenmore" #+!.... hello, thank you for making this series you are actually a very good teacher btw.
Q. If I wanted to increase my capacitance would I want to run multiple capacitors in series or Parallel? I think if I put them in series I will get the same amps and if parallel I will increase the amps ... is this correct?

Smart
I want more! and faster! ;)
*Summary:*
- an relay oscillator is an electronic component that quickly switches between turning a circuit on (completing it) and off (opening it)
- in our example, our oscillator controlled the circuit to the speaker
I don't think speakers are polarized
Wo ist der nächste Viedo?
Charles Platt shows this in his 1st book.
why not call it a repeater relay or a repeated relay instead that will make it simple understand ?
You should have put in a variable capacitor.
why aren't you uploading more videos.
Bro this video is only 9 days old :P
So this is how the turn indicators in cars work.
amazing.i like you so so much.
hay man do some things for me make a 30 000 E M P watt device for me I will copy it after wards
we want inductor lesson

me : *GET TO DA CHOPPAH*
I want my computer!!!!!!
Tesla's the best I this stuff(that is why I am learning)

This circuit is working better at oscillation.
It sounds like the intro to 60 minutes.
