- Even just a few years ago, smart homes were not a thing.

Or, they were, but you had to be

a total nerd or super rich to have one.

Now everything's different.

If you have an Amazon Echo, you have

the beginning of a smart home.

If you have any appliance you can turn on or off

from your phone, you have part of a smart home.

It turns out that smart homes are really easy

to start building, now a days.

And you can do some pretty cool things with them,

like control your lights, your heating, your TV.

You're often more limited by what would

be dumb and excessive, than what you actually want to do.

So, how do you get started?

We're gonna go to my apartment and I'm going

to show you what you can do for under $200 dollars

to make you're home a little bit smarter.

(snappy upbeat music)

Alright, so the first place to start is a voice assistant.

I'll admit, these can be kinda creepy,

but once you start to get used to them,

they actually turn into a fun and pretty convenient way

to control your stuff.

I chose the Google Home Mini.

It's $49 but they're on sale all the time,

so don't pay that much.

Obviously, you can use this to look stuff up,

or play music or podcasts, but I mostly use mine

to turn my lights and air conditioner on and off.

I could just use a button or do it in my phone,

as I see a lot more convenient a lot of the time,

especially if I'm on my way out the door

or going to bed.

Now, we're going to get into the smart lights

and how I turned a dumb air conditioner

into a smart one, but before I do that,

I want to talk about how all these devices

are talking to each other. 'Cause there's a lot going on

and it can get pretty confusing.

(energetic music)

You're probably familiar with Bluetooth and Wi-fi.

Bluetooth is great for things like fitness trackers,

headphones, mice and keyboards.

And Wi-fi is great for, well, bringing internet

to your laptop, smartphone, smart tv, and so on.

But they're using different gagets for a reason.

They're designed to do different things.

Bluetooth is pretty slow at transferring data

and it can't travel very far,

but it doesn't use a ton of power.

Wi-fi is really fast and can travel farther,

but it does use a ton of power.

There's really only one distinction

that you have to remember.

Bluetooth gadgets usually aren't connected to the internet,

so, unless you connect them to some kind of hub,

you can't control them while you're out of the home.

Where things get more complicated

is when you get deeper into smart home tech.

Turns out, Bluetooth and Wi-fi

just don't fit the bill for everything.

Neither are great for things like lightbulbs

that need to be reached at the way far end of the house.

For that, there are other wireless technologies,

like Zigbee and Z-wave.

These use really tiny amounts of energy.

So, you can have sensors sitting around

on battery power for months.

But that means they're super slow at transmitting data.

They're also built to travel much farther,

because their messages can jump around.

So, one lightbulb can transmit an off command

to the next one and the next one, and so on.

What this means is that, if you're buying something,

you'll have to make sure it actually works with your stuff.

One of the things that you're gonna need a hub for

is smart lights.

I think the best smart lights are from Philips Hue

and you'll want to start with their starter kit,

because it comes with that hub, which is gonna hook up

to your router, so that everything can talk together.

The starter kit costs $64 dollars.

It comes with a bunch of bulbs and, while Philips

has a bunch of, like, color changing stuff, too.

Don't worry about that.

It's just more than you need.

Smart lights are great for just

a bunch of little conveniences.

You can have them automatically come on when you come home

or when the sun goes down.

I bet you have at least one speaker in your house

that isn't smart or could be smarter.

For $35 you can plug a Chromecast Audio into it

and it will be able to do a lot more.

So, I have this two speaker system here.

It's old, it's from 2004 or something, but

if I hook the Chromecast Audio up

by pluging into the AUX port, I can now control it

from my phone or do this, I can say

"Hey Google, play Childish Gambino on those speakers".

[Google Voice] - Alright, Donald Glover from Spotify...

- And there we go.

- [Google Voice] - Playing on both speakers.

("This is America" playing on the speakers)

- Alright, so the last thing is a smart plug.

It's basically just an individual outlet

that you can plug something into and then turn on and off.

I got TP-link's Kasa, you can get

a two pack of them for $45 bucks.

So, these things are really cool because they're all at once

really versitle, but also really limited,

because they literally just turn things on and off.

So, I connected my two air conditioners to them,

so that I can control them and turn them on

when I'm coming home from work.

Now, some caveats.

They are literally just killing power to these things

and turning them back on.

They can't control anything at all.

So, my air conditioner, it turns out,

will automatically resume it's prior state

when it turns back on.

So, because of that, this works out really well,

because, I can just flip it on and it's just gonna

start making things cool again.

You can use this for things like fans and lamps, too,

that are just gonna automatically resume their same state.

So, that's it, that's just about $200 dollars.

But there's a lot more you can do with

the stuff you already have, if you want to get

a little bit more complicated.

Using apps in your phone, you can hook things together

to do even more.

There's a service called IFTTT, If This Than That.

That's really good for this.

So, for instance, I set up a rule saying that

if it's over 80 degrees in Brooklyn, my air conditioner

will automatically turn on and you can do that

for all kinds of stuff, with your lights,

with your speakers.

Now, I really think the best way to get

into your smart home is to do it piece by piece, like this.

Buy one thing, see how it works for you,

and then get whatever else makes sense next.

Now, I went with the Google Home Mini,

but it might make more sense for you

to go with Alexa, or if you use tons of Apple devices,

to go with the HomeKit system.

Just start with whatever works for you

and then add on, bit by bit, and before you know it,

you're gonna have a much smarter home.

Armies and Tactics: Oblique Order - Duration: 11:02.

This video is sponsored by the Great Courses Plus.

Go to thegreatcoursesplus.com to start your free trial today.

We promised to cover various tactics and strategies used by the generals throughout history in

our Armies and Tactics series.

In this video we will talk about the Oblique Order.

As many other stories, this one starts in the Ancient Greece.

Between 431 and 404 BC Sparta and its allies in the Peloponnesian league against Athens

and its allies in the Delian league in the conflict that would be later known as the

Second Peloponnesian war.

Sparta had won and became the hegemonic power in Greece.

Eventually Sparta's growing appetite backfired and led to the war against Thebes.

At that point in time, the Greek armies moved away from the rigid military structure of

the period before the Persian Invasions.

The hoplite phalanx remained the main battle unit, but the city-states started adding skirmishers

and cavalry to the mix.

However, in this period, before Philip of Macedon revolutionized the Greek warfare,

both the missile units and the horsemen were mainly used against the counterparts.

We will talk about Philip's army in our future videos in this series, but suffice

to say that the combined arms approach was not used, so the Greek armies of the period

lacked mobility and most battles came down to the numbers, quality and discipline of

the hoplites.

In the early days of the hoplite warfare, two phalanxes fought head on, but the Peloponnesian

wars changed that, as they were conflicts between alliances, so often more than one

phalanx participated in the battle on each of the sides.

This created a unique problem: the hoplites held their shield in the right hand, so their

left side was left undefended, so even the most disciplined of the phalanx drifted to

the right, as each of the hoplites tried to get a better protection behind the shield

of the hoplite next to him.

The Greeks found two solutions to this problem: some generals placed the phalanx of the city-state,

which was defending the territory in question or the best, most disciplined phalanx on the

right flank to prevent this drift.

Other commanders often embraced the drift, and this almost exclusively resulted in the

right flanks winning against the enemy's left flank.

In this variant the right flanks then would eventually meet the right flank of the enemy

and that engagement would decide the fate of the battle.

It would all change at the battle of Leuctra of 371 BC between the forces of Sparta and

its allies led by the Spartan king Cleombrotus I against the Theban-led Boeotian League led

by general Epaminondas.

Cleombrotus had 10 thousand hoplites, alongside a thousand skirmishers and a thousand horsemen.

His forces were divided into 4 phalanxes, each of them formed into 12 lines with cavalry

in front of the infantry and the skirmishers as the vanguard.

The Spartans themselves manned the extreme right flank.

8 thousand hoplites of Epaminondas were divided into 4 phalanxes with 1500 cavalry in front

of them.

Most of the Theban infantry was on the extreme left, where they formed up into 50 ranks,

while the other 3 phalanxes were weakened and had less than 8 ranks.

That was a big change from the usual battle formation.

Not only Epaminondas placed his best troops, among them the famous Sacred Band of Thebes

on the left, he also decidedly weakened his center and his left.

This would be later called Oblique Order, as the formation had one strong flank with

the concentrated forces.

The battle started with Spartan skirmishers attacking Theban camp and forcing the camp

followers to join the hoplites.

No other information is given on these skirmishers, so it is assumed that they eventually moved

to the rear of the Spartan army.

Then, the cavalry forces engaged each other and although the Thebans easily shattered

the formation of their counterparts, their subsequent attack on the enemy right flank

failed, as the Spartans managed to shift to the right and dispersed these unit.

Now that the cavalry lost its ability to affect the fate of the battle, it was time for infantry.

All of the Spartan phalanxes moved forward.

Epaminondas sent his strongest left phalanx forward, while his weaker central and right

phalanxes slowly shifted to the right.

Thebans charged into the Spartan hoplites and soon the legendary Lacedaemonians were

pushed back, their leader wounded and their formation scattered.

Seeing the Spartans retreating, allied phalanxes left the field.

Epaminondas won the battle using new Oblique Order tactic and the Theban hegemony over

Greece began.

It is important to explain why the Oblique Order was so effective.

The phalanx lacked maneuverability, so the allied phalanx couldn't support the Spartans.

At the same time, the army had no reserve force that could have supported the Spartan

phalanx and alleviated the pressure.

The lack of cavalry protecting infantry from the flank was another problem for the Spartans.

At the same time, Oblique Order is all about balance.

The general using this tactic needed to have a strong enough force at the point of attack

to break the enemy, but also keep the other parts of his formation at least capable enough

of stopping the enemy attack against them.

It should also be mentioned that Philip of Macedon who lived as a hostage in Thebes growing

up most certainly learned about this tactic and later used the variants of it in his battles,

but his strategies will be covered in a later video.

As the armies started keeping forces in reserve and using cavalry predominantly on the flanks,

this tactic was used less sparingly in the next 2 millennia.

Using a tactic like that against a knightly army or a steppe force would have been disastrous.

It is not a surprise that this tactic was revived in the era of the line infantry, when

the formations became rigid once again.

This time Frederick the Great of Prussia would use it during the Silesian and Seven Years'

War.

Previously we covered the battle of Hohenfriedberg fought in 1745 between Austria and Prussia,

so you can watch how this battle unfolded by clicking the card over here.

In short, Frederick strengthened his right flank and sent it against the Austrian left.

As this position was overrun by the Prussians, more and more of their troops arrived and

joined the right flank in their attack.

Despite having fewer troops, Frederick managed to gain numerical superiority in every location

and won the battle decisively using the Oblique Order.

His enemies had mobile cavalry and reserve behind their main line, but the line infantry

had a big problem – it was very slow to turn and enter a new formation, almost as

a phalanx.

So, the line formation wasn't able to respond properly to any attack but a frontal one.

The Prussian king managed to win more battles in this vein and we are planning to cover

them in future, but eventually his main rivals - the Austrians managed to find counter-measures.

They started employing more light cavalry to screen the flanks and support them.

At the same time, according to new Austrian doctrines, the flanks were often positioned

with a natural obstacles protecting them from being outflanked.

The French Emperor Napoleon managed to make his armies even more mobile, with infusion

of the light cavalry.

At the same time, his infantry was taught to fight both in the line and column formation,

so it had easier time turning to face the foe.

Other European armies slowly evolved under his influence which made the Oblique Order

more difficult to use.

However, Napoleon still managed to employ a variant of this tactic.

In one of our Napoleonic War videos we covered the battle of Friedland of 1807.

In this battle Napoleon had a decided advantage in numbers, but he still strengthened his

right flank under Ney and sent it against the Russian left.

Ney slowly mopped up the enemy forces crushing the left and then the center and the right.

As Napoleon had numerical superiority in other areas, Russian general Bennigsen wasn't

able to send any reinforcements to support his units.

Napoleon would have won this battle even without using oblique order, but this tactic allowed

him to win decisively.

The defeat forced his enemies to sign the treaty of Tilsit that made France the hegemon

of Europe.

Designer: Using the FileLog Instruction - Duration: 1:47.

This instruction is used to log the data found in this table based upon these conditions.

Only BRX PLCs have the SD Card File System, but all Do-mores have a useable RAM File System

if they have above version 2.0 firmware.

This is the full path of the file to use for logging.

Notice that the File name by default shows quotation marks, this indicates that you are

using text and not a string.

Now if you want to use a string tag here, just insert the tag here.

For the Input leg you can select edge triggered so that this instruction logs when there is

an off to on transition or you can select Power flow enabled and then have one of these

5 options for time base of the logging.

I strongly advise using this option.

It appends the File name with a Timestamp.

At the same time I advise using the "Generated File Name" this will store the name into a

string tag.

This string then can be used by other FILE instructions to target the current and complete

file name generated from the File Log.

There can be up to 50 entries in this table and there can be a max count of 10 elements

per entry.

This instruction can be used in Task or Program but cannot be used in Subroutines or Interrupt

service routines.

There is a utility program called Browse PLC File Systems to manage the contents of any

file system.

This can be found, while the designer software is connected to the PLC, and selecting PLC->

Browse PLC.

File system.
