Waching daily Jan 31 2019

My name is Alvyn Severien. I'm CEO and co-founder of the company ALGAMA.

Right now, the food industry is quite broken, because it's the most policing industry

in the world, and has so many health issues with what we're eating on daily

basis. ALGAMA is a company that mainstreams the use of microalgae for the food

industry. Algae are extremely healthy, because it has up to 70% of protein, all the B

vitamins, a lot of minerals like iron, magnesium, calcium in crazy amounts.

It has also a lot of unsaturated fatty acids that are very healthy and very

useful for the body. So it makes it a superfood. Right now, we have created one

range of land-based mayonnaise, but it's half the fat, no cholesterol, no

preservative, no gluten. Super taste and texture - everything you want when

you eat mayo, but without all the bad aspects. Every product we're working on,

we want to bring something super tasty, and how we can create the best

products of their categories. Every time we can do a product out there and more

sustainable, that's one step forward.

Is It Still Possible To Make Money Off Wine? - Duration: 4:11.

Humans have been drinking wine for at least 8,000 years.

And in that time it's been a drink of luxury and leisure, religious rites, and celebrations.

There are investment wines, table wines, natural wines, and sparkling wines, and the one thing

that seems to link all of them?

They're not cheap.

So is the wine business only for the rich, or is there room for anyone to make money?

Most expensive wine comes from France.

So it makes sense that most of our vocabulary about wine comes from France as well.

In the wine world, the word for an expert is "sommelier".

And I talked to one to help me understand what makes a wine worth it.

My name is Madeleine Hayles.

I do private wine consulting for events and personal wine buying.

And according to her, one of the main reasons wine is so expensive to buy,

is because it's incredibly expensive to make.

Before you even get to the grapes, there's the soil.

And in wine, the soil matters - a lot.

Wine is all about terroir [terr-woir] - a French term that basically encapsulates the

way that the soil, climate, weather, and other elements in a region influence the way the grapes grow and taste.

And so places that have a history of making good grapes and good wine, are more desirable

to both wine producers and wine buyers.

So when you're buying vineyard acreage, you're really buying the terroir of that piece of

land or part of the world.

The better the terroir, the more you'll have to pay for the land, and, the more you get

to charge for the wine that's made there.

But what makes good land exactly?

And how can you tell just "how" good it is?

The French, of course, have a system for that.

Most wines are labelled according to the grape variety that they come from,

like Sauvignon blanc, Cabernet sauvignon, or Pinot noir.

But France has over 200 varieties of grapes.

And because there are so many, a lot of French wine is made with

a combination of two or more different varieties.

And because of that, French wines are labelled according

to the region of France that the grapes are grown in

instead of the grapes that the wine is made from.

Each region has its own rules about how wine should be made there and wines are given a

certification based on how strictly they adhere to those rules.

There are four rankings for land, and the highest can be extremely expensive.

A hectare of the best land costs an average of €66,500.

The same amount of land in Champagne, the namesake of Champagne wine, costs €1,000,000 on average.

And the best land, in the Burgundy region, fetches €3,000,000 a hectare.

It's really hard to know if the terroir of those vineyards warrants those prices

just because it's hard to know what $2,500 is supposed to taste like.

With all this talk about vines and vineyards.

It's easy to forget that growing grapes is farming.

And, like all farmers, wineries and vineyards, buy and sell grapes all the time.

And because you can buy the fruit without needing to own the land there are some very

good wineries that don't own a single grape vine.

For example, you can buy one ton of Cabernet Sauvignon grapes from the Napa Valley for $7,000.

And a bottle of wine is made from about 6-800 grapes,

meaning that ton of grapes will become 720 bottles of wine.

So the cost of grapes alone for each of those bottles is almost $10.

And once that wine is in those bottles,

those wineries aren't the ones that get them to your dinner table.

That's the job of wine importers.

They find the best wine from around the world and make sure it gets in the hand of the restaurants,

private wine shops, and private cellars where they'll be most appreciated and enjoyed.

So after all that effort, money, and care, it seems like a waste to not drink it.

But wine - especially expensive wine - does end up in cellars, being kept for years to

make those expensive bottles even more expensive.

I don't know if it's necessarily something

that I advocate because I really think that wines are for drinking.

It's like buying a beautiful piece of art and putting it in your garage and nobody ever sees it.

And while the wine we're drinking today may not make us rich,

holding on to it for 50 years or so just might.

Mynd Vlogbuch Staffel 2 Episode #4 | Live is Live - Duration: 7:07.

Now we drive over to the crew

and see how far they are packing up with equipment

the actor should already be there and sitting in the mask.

And then it starts!

Today we're shooting real, we're on the road a lot in the city.

We also have a lot of shots in town and a lot of driving scenes,

I just collect the customer,

she sits with me in the car

and we follow the crew and the whole team.

We are now here in Frankfurt and shoot some scenes,

I do the camera. He takes care of the sharpness, that's the director who says where we're going.

Well, we should get going!

Wave a wave !

Hi, I'm Linda from K-fee

and we're here in Frankfurt today

and making a pretty cool movie

for a new brand that we're going to bring to market.

Sometimes you're also used as a disturber during such shoots,

like an additional, by walking through the picture.

But you're not actually shown or seen at all,

that's just blurry.

3, 2, 1 and go.

We now drive to location 2,

thank God into the warmth,

and then we go on.

Okay, let's go to the beginning.

I think this is the most exciting recording,

we take the book over and then....

I'm the new intern at Mynd in Producing,

it's a lot of fun.

You get to see all the professionals at work.

We are like 15 people...

and therefore also quite good at timing.

And action!

Thank you very much, it's a wrap!

The end of the shoot!

Good morning, we are now here, just half past six.

Half 6 here means 14:30 in Germany.

And that means, we have the first call right now and start the day

with the lovely Chantal

and a lot of marketing.

Hello!

Hello!

Who's haunting around?

What is there?

Hi there!

Hello, how are you?

I'm doing very well. A bit tired.

Yeah super nice, nice to meet you.

I have to go now again,

we have another customer there. Bye.

Marcel, do something, okay? Thanks.

It's now about strategic alignment for Instagram.

I've been thinking about the other channels.

Because that's what we wanted to adapt.

I have to say, I wouldn't differentiate it that much.

So what I did:

I actually only took a closer look at the target groups,

Facebook and LinkedIn,

and I'm concerned with

also in terms of SK and LA...

...how we can bring everything even closer together,

So dear people,

we're going to a really great event now,

it's called Silikon Beach.

Very recommendable.

And yeah, let's see,

we definitely have to eat something on the way.

I'm hungry as hell.

Look, that's where we live!

and when I say we,

I mean me again.

Then we drive off now.

Why are we going there:

There are a lot of events in this funny city

and there are some really cool presentations today.

In the end it's networking and free drinks -

hopefully also free food...

like I said before, I'm hungry.

The traffic in this funny city is completely absurd.

Because here 4 million other people -

each one individually - get into their own car...

which of course I didn't do...

Whoo-hoo, Highway!

WHOO!

So, now we are right there.

So, networking:

grinning and talking shit.

I can do that.

So dear people,

that was funny.

The funniest thing was ...

that after the first 3-4 shots...

someone came to me and said

naaah, don't film.

Was nice,

had quite good conversations,

you had to take with you.

We have a few contacts...

and now let's see

what else we can do with the evening.

It's time!

Moritz, you've seen what we've been doing all these weeks

and you've even seen it happen.

Today is the day:

"Mynd live" goes online!

Our format for encounters.

"Mynd live" is intended for all the people...

who want to get to know us...

and whom we would like to get to know above all.

These are events, whether online or here in Frankfurt,

where we can talk about specific topics

- all of course with reference to videos -

and it doesn't matter whether you are the managing director or the intern.

Because I think everyone needs to know what videos can do.

And that's why I'm sitting here in our studio now and I think it's become wonderful.

On our website there is now a huge calendar with many different events,

which is getting fuller and fuller.

The whole thing is free of charge.

The first meeting is on the 5th of February with our managing director and founder Attila Schunke.

We have a format, the "Welcometalk",

and in the "Welcometalk" you learn what our products are, what video styles we have

and you can ask questions afterwards.

Another format is e.g. the expert session,

where two video specialists from Mynd come together to talk about a specific topic.

And of course we will also have events here at some point in the future.

Workshops, house tours, "Get togethers" after work for a nice beer -

that's "Mynd live"!

Moritz, it's time! In a few minutes it starts,

then "Mynd live" goes online

and I'm so excited!

All I have to do is push a button. A single button.

It is this one.

Publish.

Moritz I click now! I click now! I click now!

HOW TO SEE | Judson Dance Theater: The Work Is Never Done - Duration: 10:14.

Yvonne: Well, I can see right off the bat that I came into this situation with certain

reservations about performing during the day in this huge space with this constant buzz

of museum-goers, but I resigned myself to it and I thought it was a very good situation.

Ana: People were pretty focused, somehow.

Yvonne: Yeah, look.

Pat: And also, they don't know they're gonna stand there for five minutes.

They're waiting to see what happens so they're attentive.

Patricia: Do you direct them to be dead serious or…?

Yvonne: Yeah, yeah.

I didn't tell them not to blink or, you know…

Patricia: Smile but not to smile.

Yvonne: It's an individual matter how you stand still.

Patricia: They have to count?

Yvonne: No but they have music to…

Pat: No, they know the music.

They recognize the shift in the music when they are to begin to run which is…

The shift in the music starts in about 10 seconds.

Ana: You both did it, no?

Patricia: I've never done it before.

Ana: You never did it?

No?

Pat: Never done it, no.

Yvonne: I've done it.

Patricia: Really?

Pat: But you did it barefoot.

That's what interested me.

Yvonne: Yeah, that was the difference.

Pat: The most important thing is to keep the shape of the clump.

Patricia: But the individuals inside can't move.

Pat: Can't move around.

They sometimes have to position themselves that they have a breakaway.

There.

You broke away really easily right there, but sometimes it was awkward.

Patricia: Well, every time they came back into the dressing room when we were warming

up…

Ana: They would be talking about…

Patricia: …they would be, like, you know, all the difficulties of navigating that space.

Pat: Yeah, yeah.

They should be closer together.

Yvonne: See, now here they should be…

Pat: They're too spread out.

Yvonne: …closer together.

Pat: Yeah, yeah.

Whatever were they thinking?

Yvonne: Come on.

Get together.

Pat: Well, it's hard, in a way, to run when you're in the center because you're just kind

of going around yourself.

Now these two people, I taught this to them in Dublin because they were dancers I chose

for Yvonne's performance at the Irish Museum of Modern Art.

Thomas: Do you think it makes any difference whether the dancers are people you know or

don't know?

Like, back in the day, these were folks that you were working with and you knew their work.

I'm just wondering, like, in terms of how close you get or how far you get.

Yvonne: My own group I've been working with some of you since 2000…

Pat: 1999, 2000.

Yvonne: Well, Pat...

Pat: ...forever but...

Ana: 1931.

Pat: Yeah, just about.

Yvonne: With new people, yeah, it's a different situation, yeah, in my experience.

Pat, what's yours?

Pat: Well, it is like you have to kind of get used to what kind of instructions people

respond to and what kind of instructions they don't get.

Patricia: Like this woman, Mary Kate, I would've never thought that she would be a Trio A-er.

Yvonne: Why?

Patricia: Because of her training.

She performs in more presentational kinds of works/choreographers, but she did so great.

Pat: She grasped details of performance and gesture immediately and retains it.

Patricia: She had, like, an athletic energy…

Pat: Yeah, she has an athleticism that's really beautiful.

Patricia: …that it was so fantastic to see it.

Pat: There's something about a white man with no hair in Trump's, you know, reign in this

country.

Think of, like, White supremacist or something, you know, with the flag.

Even though it is a commentary…

Yvonne: Oh, oh, the flag.

Pat: …on nationalism.

Yvonne: I thought you were trying to imagine Trump doing this.

Pat: I think we should now that the government will never be ...

Thomas: That's a frightening image.

Oh, my God.

That will never get out of my head.

Pat: Here comes the star.

Patricia: Everybody talked about this coat to me.

Yvonne: Why?

Patricia: Like, is this character from a French film?

Yvonne: Why a French film?

Patricia: I have no idea.

Because it's elegant, it's minimalist?

Yvonne: What does that have to do with French film?

Patricia: I think there was something communicated by the costume this time than ever before

that she was in a train station or something, you know, running to catch the train.

Like, that was a whole narrative that never we've had there before.

Yvonne: Well, the other weird thing is you're not allowed to take your hands out of your

pockets.

You have to get up…

Patricia: I mean it's hard to run, like, in bare feet and all.

But, I really got in shape.

People applauded the running.

Yvonne: They thought it was over.

Oh, I love this part.

Patricia: You taught me.

You taught me everything I know.

Pat: That smile is particularly bizarre.

Patricia: I mean I've been doing this for 10, 12 years, 15 years.

I remember the first day that you came to the…it was, like, 2001.

She was looking for somebody who could scream.

Yvonne: In a theatrical setting, she would get up and…yeah, and as she turns her head

to the left, the lights fade to black.

So, I think I gave you special instructions, milk it.

Patricia: Use it.

Take your time.

Yvonne: Take your time.

Patricia: And that was, like, the hardest part to…

Pat: The hardest thing to do, I would think, yeah.

Patricia: And because I would see every single person in the audience.

I would cry.

Yvonne: Oh, this is beautiful.

Oh, my God.

Oh, my God.

It's great as a closeup.

Pat: It's beautiful.

Yvonne: I was involved in repetition at that time and randomness.

Yeah, it's not choreographed the overall structure.

Each movement has a number.

Pat: Or a letter.

Yvonne: Or a letter.

Patricia: And anybody can call it.

Yvonne: If you want to change a diagonal, you tap someone and go on a different diagonal.

Pat: This is six.

She's doing nine, which nobody likes to do.

She got abandoned.

It's a C.

Yvonne: It's a two

Pat: It's a C.

Patricia: So now David just touched Emily and they changed directions.

Yvonne: Yeah, and they'd go to a different corner.

Patricia: And you have to stay moving like that in the corner.

Yvonne: You do this treading motion.

Ana: What are you doing, Pat?

Pat: I'm doing random walking.

Patricia: What you see is what you get.

Pat: I just did D3, I think.

And I stopped still which you can do in the random walking, but you can't move again unless

someone jostles you.

Here comes, Ms. Yvonne.

Patricia: We didn't know Yvonne was coming in.

Ana: You didn't?

Pat: No.

Patricia: No.

Yvonne: No, this is the first time.

I just came in and stood.

Patricia: Everybody's smiling because we're like, "What is Yvonne doing here?"

Pat: Like, "What the hell?"

When she started coming out, I thought, "Oh, she's going to come out and tell us we're

doing something wrong."

Patricia: Like, in the middle of the performance, Yvonne would be like, "I don't know what three

is," so we would have to do, like, a quick…

Ana: Update.

Patricia: Update, yeah.

Oh, Yvonne, now you joined the group.

Pat: That was eight.

Yvonne: That's enough of that.

Patricia: The privileges of the boss, you go in and out when you want.

Yvonne: Now I'm in the group.

Pat: Raise your head, Yvonne.

Why are you looking at the floor?

Ana: It's really hard to watch yourself.

Yvonne: Oh, dear.

Pat: This is three.

Patricia: Okay, forget it.

Yvonne: I'm not going to do that.

Yvonne: What am I doing?

Pat: You're getting us to come out.

Patricia: And she's out there by herself.

It's like, "Come on out."

Pat: But when we were done, I mean we were all performing at age one hundred like twice

a day.

So we were like, "Okay, we're done," but at the same time, it felt like it was just the

beginning like there was something happening.

Yvonne: What am I going to do?

What do you want from me?

Patricia: You were happy.

Yvonne: Of course.

Patricia: You were so happy.

Yvonne: Yeah, I was very happy.

Yeah.

Ten-tweet thread of Jurgen Klopp's strangest excuses at Liverpool is going viral - Duration: 4:15.

 The frustration was visibly building for Jurgen Klopp during their draw with Leicester City this week

 Liverpool were looking to extend their lead at the top of the Premier League to seven points, having watched Manchester City slump to defeat against Newcastle United

 However, despite leading through Sadio Mane after just three minutes, Harry Maguire responded before half-time to ensure the points were shared on Merseyside

 Numerous clips on BT Sport showed Klopp getting more and more angry with his players as they pushed for a winner during the second-half

 Yet few clearcut chances were forthcoming and Naby Keita had a penalty shout turned down, meaning that all of Klopp's animated reactions on the touchline were in vain

Klopp's comments on the snow  As far as the German was concerned, though, the weather was guilty of interfering with the game and he complained about the snow on the Anfield pitch in his post-match interview

 Klopp explained to the media: "The pitch was difficult and we needed to speed it up in the final third

Our counter-attacks in the opening moments were defended more by the pitch than our opponents!"  It's not the first time that Klopp has pointed the finger at mother nature this season, expressing his frustration with wind after their FA Cup elimination at Wolverhampton Wanderers

Twitter thread of Klopp's excuses  One football fan in particular has started to notice this pattern with Klopp after games and it seems there are countless examples of him offering question excuses

 Twitter user 'Ruining football' decided to compile all of the quotes in one place, taking screenshots of media outlets reporting the comments and bringing them together in a 10-tweet thread

 Despite having a modest following of around 600 people, they've managed to garner over 1,000 retweets and 'likes' in the space of a few hours

It's fair to say supporters are finding it funny.  Check out some of the finest tweets from thread:   We can't embed the full set of tweets, but you can check out the entire thread here

 Fans knew that Klopp had mustered some bizarre excuses across his career, but the evidence really starts to pile up when you put it like that

 Solely drawing on case studies from Klopp's time with Liverpool, the thread sees him blame everything from the Hawthorn's pitch being too dry and BT Sport allegedly trying to shorten a game

   That's not to mention the countless times he's passed comment on the wind affecting Liverpool's performance

 Admittedly, some of the cases are a little harsh and Klopp isn't necessarily shovelling all the blame on meteorology, but it's no surprise fans are starting to chuckle after so many instances

 The Met office should brace themselves for complaints if Liverpool miss out on the league

 Do you think Liverpool will win the league this season? Have your say in the comments section below

Battery Management System. What is a BMS realy doing? - Duration: 14:37.

Hi I want to talk about...

...battery management systems

It's

for example for the 18650

batteries I bought a bunch of battery holders for this battery and

I've solder

battery management system on this so I don't want to explain how to

Connect the battery management system

To the batteries. Because there are a lot of youtubers who posted that already.

You just connect the four batteries in series like this

And you just connect them to the BMS and that's what I wanted to talk about because...

...I thought the battery management system

Will balance the batteries out. So you have four batteries and the battery management system

Wants to balance the batteries, but that's not true.

The balancing board of the BMS is not balancing the batteries voltages.

So, what do they do? Well..

I have an example here

There is a BMS board at the back of this battery pack. I took one battery out and...

I've connected a little power supply

Instead of the battery. So the power supply is acting like if it's a battery

So now I can change the voltage of one of the batteries

So I can act like one of the batteries is running out. So what you see here is an ammeter

It's measuring 11 milliamps because of the voltage meter that I have connected.

And this voltage meter is drawing 11 milliamps.

You can see all the batteries are 3.8 volts. The cells that are inside, will not change voltage.

Don't worry about that.

The 3.8 volts wil not change.

To see what exactly happens, I will...

...disconnect the voltage meter. So now the ammeter is measuring no currents.

But there is still 3.5 volts here.

Now 3.6... 3.8... 3.9

4 volts!

Now the battery is almost full that's supposed to be in here. These batteries are still 3.8

So there is a voltage difference. Why is the balancing board not balancing these batteries out?

That's because they are not supposed to do that. BMS is not designed to

Balance the batteries out when there's nothing happening

the only thing

Something is going to happen is when the voltage of the charged battery is too high now watch what happens

Four point....

Oh cool...

You see that?

now the voltage is much too high because the maximum voltage of the 18650 batteries is

4.2

Now, this is much too high

So there is a current the battery management system is drawing and currents from this

battery and that current is

60 milliamps now, I lower the voltage I

Lower it

Look

Now the current is gone

So that battery is not draining its energy anymore

It stays stable. This is the battery management system

Now I will show the BMS up very close to my good old microscope

Here it is...

And yeah, there's a lot to do here.

So, what is all that?

These are MOSFETs

These are resistors

So what's happening here, well, I have a schematic

Now don't be scared

It's not that complicated. I will show you the schematic from closer

Closer even closer now. Let's go up

closer up

Here are the connections. This is the B+

This is the b3 connection

This is the p+ connection also they're together the B+ and the P plus

the b3 is not connected to some other connection. Now you can see the B+ and

the P

Here this is the B+, this is the P+ plus now closer

Look P+..B+ are connected together

Like the schematic had showed us.

B3 connection...

...is here. You can't read it because there is a wire running over it. But this is the b3 connection. So this

These two connections are connected to one of the batteries. Now, let's go back to the schematic

Closer

Higher

This is where we were

So this lead

All the way up is all connected to the B+ and this lead

Here horizontally

it's connected to the

Minus of this battery, so there is a battery between here

now

If we go to the right

Then we can see a little schematic a very simple little schematic here

So here is a battery. This is the plus. This is the minus. Can you see my mouse?

And everything that's between those two leads is schematic. Now, we can see two resistors here

those two resistors...

...are oh

Sorry this one,. Look those are the resistors

Those two

Are connected to the B+ Can you see that?

So those two...

...resistors are...

...acting as a load.

So back to the schematic. Oh sorry about that. I go back

here

Those are the two resistors, they're a load. So this is a MOSFET

This is some kind of IC that will take care of the over voltage

because when the voltage is higher

then 4.2 volts, it will...

activate the MOSFET and...

...that MOSFET is connecting those two resistors to the minus of the battery.

So that's the over voltage protection.

And that protection is for every battery. This is battery one

This is the same schematic for battery two

This is the same schematic for battery three, and this is the same schematic for battery 4

So this is quite clear. This part of the schematic is for the over voltage

Now we have this part of the schematic. Look they're all the same this part for battery one

battery 2

battery 3 and battery 4. This part is

Connected to this part of the schematic now, what is that for kind of part?

These are all MOSFETs these MOSFETs

Can disconnect these two leads. So the minus of the battery and

the minus of the load or the charger

Could be both... That minus can be disconnected by the MOSFETs.

Now, what is turning these MOSFETs on and off?

Those are all dis

Parts of the schematic

So let's test that out. I've just showed you what the

over voltage protection

Looks like.

It's on

Now it's off. The over voltage protection is working. But what happens when you have an under voltage?

Well, then we need a load. The output switch will do nothing without a load

So we need a load.

I have just connected an LED. You can see that the output is switched on now the voltage of that output

Is 15.5 volts.

That's the total voltage of all the four batteries

So there is a very little load

This LED is only drawing 20 milliamps. Here we are.

okay.

That battery has a very low capacity

So it's running out very fast. Here we go, Oh, oh, dear. Oh, dear

My battery's running out and it's the only one of that four batteries. That is so bad

But the output is still on. Now we go to a critical point of the voltage

2.6 2.5 2.4 Oh...

Okay, so the output is turned off by the MOSFETs now. And if the voltage is coming up again...

...nothing happens

What's

Oh, the over voltage still works

But the output is not turning on

because you have to disconnect the load...

And then the output will turn itself on

You see? Now it's on again. Let's do that again

The battery is running out

2.5 2.4

Oh, the output is off again. So that part of the schematic

It's functioning great

the left part

I showed you the right part. That's the over voltage protection. Now this is the under voltage protection.

So when the voltage is running out

The leads on the left side

Over here. That leads go down... Way down.. All the way down

To this part of the schematic and those are the switches. The MOSFETs that will switch the output off

So that's all a BMS is doing. It's an over-voltage protection...

...but it's also an under voltage protection.

It will not balance the batteries out when there is nothing happening

The only point where the batteries are...

...balanced is when the batteries are getting charged all the way up to 4.2 volts

Because then the over voltage protection...

...is going to take care of the batteries

balancing moment

That's 4.2 volts when the batteries are getting charged they are balanced

But if the capacity from the four batteries is not the same

Then the outputs will turn off when the lowest capacity

Battery is running out

So if these better very good, and there is only one bad battery

Then the whole package will turn itself off when the lowest battery the baddest battery is running out

So if you have a electric bicycle with a battery pack, that is bad

You can open it and just find the baddest battery

Replace that. And the the other batteries may still be very good.

I hope you learn something

Until the next time. Bye. Bye
