PICAXE based toy level crossing

Nothing gives as much pleasure as making a unique toy for a young child to play with. What I have created here is a toy emulating an automatic rail barrier crossing to be integrated to a toy train set. Opening and closing the gate sequences are controlled from a SONY format television remote control handset although this could be modified to accept track sensors. The main structure is manufactu...
Very bad 😞😔 not a word about the King of AC..
No mention of the Flux capacitor that makes time travel possible
370 Hell, why not? Sub. It was a good watch and listen. Very informative and helped me understand magnetic coupling better. Thanks.
Good, nice historical pictures.
How could you mentioned Westinghouse and not Tesla?
One of my grandmothers brothers worked at power station in the early 20th Century, I guess until about 1940? A kitten was electrocuted and never grow any bigger than a kitten at this station in East Kent.
Please..you must reading first...ho is making these human history.... Muslims invansaionar....is real..hero of .. human history... Today everyone has .. talking same like puppet...but REALTY is ... totally against .. western invasion..claims...
Thanks, very cool history
The power plant I started at in 79 had gone through many phases of operation throughout it's 90 yrs. Of operation, started with combustion engines running DC generators to vertical steam turbines finally horizontal steam turbines pushing AC generators
240p - a bad joke... :-(
Electricity is one of man's greatest conveniences and improvements to society and technology. Remove it and watch the world quickly collapse. Like most technologies, it began slowly at first and then rapidly developed when it became commercially feasible and profitable. My Dad was a manager of a rural electrical cooperative for 40 years. The coop brought electricity to farms and other rural customers after WWII. My dad said his greatest joy was watching the farm housewife turn on the electrical light for the first time. It was a life-changing moment for that family and farmer.
Must’ve been a great feeling. I wish I had experienced it. People try to feel good by taking drugs or drinking alcohol. The good feeling your father got was sublime and noble.
From here in the States we thank you for sharing this excellent informative video! Best of luck!
I have a Gramme motor / generator . There is an identical machine in the Berlin Science museum. It appears that they were built as demonstrators to take to customers. I suspect that it must date from 1870 but have no information about it.
Great video .
Very good.
When Faraday dropped a lodestone through a coil and current detected one lady stood up to ask Faraday what is the use of all these Michael Faraday picked up one baby and he asked Madam Could you please tell me What will be the use of this new born baby
A magnificent metaphor.
Very nteresting.
We must remember the great scientist Nikolai Tesla in our hearts forever 🎉❤.
Tesla was not a scientist. He was an engineer.
Tesla stands on the shoulders of many great giants.
Without whom George Westinghouse would not have the advantage over Edison, his 3 phase motors /alternators where a game changer!
Excellent video
Very interesting. You could have mentioned Nicolas Tesla... *** Très intéressant. Vous auriez pu mentionner Nicolas Tesla...
The autobiography of Benjamin G. Lamme includes some mention of Nikola Tesla, but, Tesla did not play that big a part in tech at the time ... one can find the autobiography online for reading.
@@uploadJ Edison publicly electrocuted animals using alternating current. This was to discredit Westinghouse's (Tesla) AC solution. The case was well known at the time and easily verifiable on the Internet.
no validity in this video Tesla was not mentioned some of his greatest work Was mentioned
Tesla/Thomas Edison... They have not invented, they have improved what others had discovered.
@@FyoutubemadridMadridno. They did invent. Others contributed to our understanding. But invention is the practical implementation of ideas into a usable product.
Nikola Tesla was the first to accurately state all magnet fields move naturally.
Now here's a great invention, the school classroom, that teaches English.Ever see one?
@peregrinemccauley5010 you mean government indoctrination? Einstein wasn't actually smart 🤣 that crossdressing, spy, thief, who married his cousin. 😂 Yeah go to public schools. You can learn more on your own in a library if you actually had a brain. Go be good little obedient materialist. The world will change around you and you'll never know Why. Till your told
I generated nuclear electricity!
I'm glad you mentioned Godalming as it' my hometown
BS... tesla
What?
Too many ppl advance what was shown by Tesla but worked out by others in Eastern Europe, in non-English speaking countries, which Tesla had access to ...
excellent video
Such Smart People 👌 😊
My Husband was a power station operator , he drive CTM Boilers and Parsons Turbines

Is the middlesex kit still available?
Outstanding explanation!!!! I would make one practical comment. The droop for the voltage regulator comes from sensing A and C phase voltage plus B phase current On each generator. This B phase CT is polarity sensitive and if connect wrong will give rise instead of droop to the voltage regulator output. This miss connection is not unccommon on new installations or where the generator has beeen removed for repair Be aware! ct
50 Hz or 60 Hz the rpm is depending of quantity of poles .3000/3600 . 1500/1800 750/900
I don’t understand what you’re saying here. Rotational speed depends on the frequency and number of poles.
Where is Nikola Tesla name ?
He did a lot, but many more did just as much. Sometimes it's nice to hear whose work he stood on the shoulders of, too.
No mention of Tesla shame on this man
Tesla invented the AC motor (in fact Tesla, Galileo Ferraris and Mikhail Dolivo-Dobrovolsky all invented one). He did not invent the generator.
@ but he engineered the first water turbines and AC transmission Of electricity to New York City
@@Hipyon I think that would be Benjamin Lamme. Tesla was a visionary who had ideas. Lamme was practical engineer who made the ideas work. He made the Tesla's motor to work.

Your video helped me a great deal! Still don't have the full concept in my head but I'm getting there. It's a lot to take in when your grasp on the basics has rusted a bit, but your video already explained a lot.
what do you mean by (( we normally synchronize super synchronously)) at 13:45 minute????
I believe it means the synchronizing generator's breaker is closed with its frequency running faster than the system's. To be 'synchronous' means to have voltage, frequency, and phase matched. Super-synchronous would then suggest having one of these parameters at a greater level. Because synching with a synchroscope needle moving in the fast direction is standard practice for tying a generator onto the system I would guess it means elevated frequency. As the video goes onto say, this ensures the synching generator loads up - which is what would happen if it was synchronized at a higher frequency.
Thank you Chris. That was allot in 18 min. I would be awesome if these videos where redone in higher quality and broken into more detailed parts .
