Hey Big Fan and a equivalent electronic enthusiast. I have Modified the Multiwii code for Airplane to work with NRF24l01 . We would like you to make and show us your plane fly .
Today I finally understood how mercury vapour tube works I bet most of the people don't know this. There are many videos on how it works but I understood with this.
Just want to say the way you explained the compact circuit was amazing. Again to reiterate... amazing. The visual graph of the signal changing as you explain the circuit was SO CLEAR and HELPFUL... Thank you!
Great video , Thanks for doing video that I asked comments. This is the proof that you read all the comments dont worry abt some people saying that you don't read comments.
Just a minor correction. 5:14 The choke is usually wound on a core made of iron slices. Do not break flurescent tubes as they can contain toxic mercury. Just a note of warning. Good video.
And..... LED came to the party. One of the greatest youtube videos, thanks a lot. very informative. Now I'm going to search on how to make a plasma ball out of this bulb :)
@@Warp3326 LED are not trash IMO, but companies running it with overvoltage and without heat spread which reduces their life from years to a couple of months. that's how they make money, they won't profit from a lightbulb that runs for 10 years.
Been following you for about four years now and am amazed by how much you still maintain the enthusiasm while explaining. Also the animations have obviously gotten significantly better.
You are the best when it comes to explaining electronics circuit and devices. I don't have words to thank you. Would love to see more such videos. You made me understand the working of the CFL like a breeze. Thanks you so much
Very well made video :-) These types are getting harder to find lately due to LED taking over. Just bought about 9 of these the other day for $1.00 a piece at a local liquidation store.
Man, you can lecture most of my professors on college, wish you the utmost success. Would you consider making a serial on CPU design, and possibly creating a fully functional CPU? Many videos online dont go in dept, or are waay to long.
Neat! I always wondered how florescent fixtures from 20 + years ago have changed, now I know! For instance I have an old florescent drafting desk lamp that has a 'start' button and an 'off' button, so the 'start' button probably takes the place of the arc.
This was a very interesting video Andrei. I find it fascinating to see the back EMF from that inductor coil's magnetic field collapsing actually being harnessed for a purpose. Thank you for creating this great video.
You're simply great. Here in Africa we enjoy your videos pretty well. If not for you, we would be in darkness with regards to technology. We are proud of you. With love from here.
Wow! Very good research and demonstration. This is good for educational purpose, recommended. Keep it going on this awesome video like this. Thank you!
I think its forced obsolescence, where manufacturers force their products to fail prematurely in order to switch to LED bulbs? Just a guess, but this has been hapenning with some products
@@narayanbandodker5482 this was long before LED lighting technology was even available. CFLs have always been terrible quality, I don't know anyone who still has CFLs (even frugal people). There was a low-mercury mandate in fluorescent tubes: these fail prematurely. CFLs are now more expensive than LED bulbs.
Frequent power on and off can shorten CFL lifespan. Also Good ventilation of the lamp is needed. From my personal experience, CFLs do last longer than incandescent lamps.
You've always been a source of inspiration to me. I love the simple explanation. What software do you always use for your physics illustrations and circuit design that looks like fritzing
need to run a uv tube from 12v to sterilize water when camping etc, either one of those 6w/8w tubes for ponds or those 3w gtl3 style ones. ( I think 24v+resistor can strike those but they prefer ac)
You r great sir !! Thank u very much. Dear sir , I want to know about wireless microphone. Please make a video on wireless microphone receiver & transmitter.
Great Video, I'm just beginning my journey into electronics and learnt quite a lot. You explained it really well. In the modern CFLs, what do you think are the main failure modes? I'm considering if it's worth salvaging the coil and some caps off the boards of nonfunctional CFLs before I throw them out.
I reckon it's definitely worth saving the high voltage caps. They usually have reasonable length wires on them. Also in many I have scrapped that have failed the transistors often still work.
the ballast inductor acts as an impedance =2piFL to control the current in the lamp. without it there is no current limit and it behaves like a short circuit.
Hello! Could you make a video on how to make a power supply transformerless for the esp’s projects? I usually use power supplies with transformer but they take a lot of space on the PCB, cheers from portugal
I have a question pls answer it . I want 2 sensors in which I kept 1 at place a and 2nd at place b. So it tell the distance bw them. And also if I move one of them up down or rigth and left then also it works. Means which are aligned to each other.
What causes the starter to cool down? Is it just the fact that because they came together, there is no more plasma creating heat and once seperated, the coil dumps and pushes enough voltage to get the tube going?
Is it possible to apply a lower voltage just enough to create a plasma but not heat it enough to bend the bi-metal? I would like to have a starter permanently lit with the argon glow.
Hey Big Fan and a equivalent electronic enthusiast. I have Modified the Multiwii code for Airplane to work with NRF24l01 . We would like you to make and show us your plane fly .
Nice explanation! But I didn't get why there are two different pairs of wires (or two different tubes) in the CFL, instead of just one? Does it make the circuit simpler (it does look similar to an astable multivibrator)?
it's not an arc inside the starter it is the same type of gas discharge that we want to have in the big tube as well, but because the electrodes are much closer to each other the starting voltage is much lower.
