Youtube daily report Mar 23 2018

In this opportunity we will make a small Introduction to the LPWAN networks based on LoRa and we will characterize the Module RFM95

Let's look for images about LoRa to get the idea ...

But .. What is LoRa ??

LoRa is a long-range radio technology in English "Lo ng- Ra nge" developed by SEMTECH its main features are ...

1. Its spread spectrum modulation allows a significantly greater range than other Max 15-20Km technologies.

2. High sensitivity (-168dB) combined with high immunity to interference.

3. Low Consumption (up to 10 years with a battery, good depends on certain characteristics).

4. Low data transfer (up to 255 bytes).

Let's first clarify that "LoRa" and "LoRaWAN" are not the same:

LoRa is the physical layer or in simple words is the modulation, the modem or radio, the hardware.

LoRaWAN is the protocol of the network or the architecture, securities and connections that work on LoRa.

lora-alliance.org is an open organization initiated by industrial leaders to standardize LPWAN networks

The idea is to position LoRaWAN in Industrial, IoT and M2M applications.

There are videos and complete documentation about LoRa and especially LoRaWAN

Let's look at some possible architectures ..

There are LoRa devices or Nodes, possibly Sensors and / or Actuators

Since it is for IoT applications, there are "Gateway" that receive information from the nodes.

The "Gateway" technically converts LoRa to Ethernet protocol and is already WLAN / LAN / 3G / 4G ... LoRaWAN already has a lot implemented

Let's look at the "LoRa" Hardware available ..

You can buy only the Radio ..

There are LoRa Modules of all price and quality which is reflected in the Final application ..

There are "shields" and integrations with platforms and microcontrollers "Pic, Arduino, ESP8266, Raspberry pi and ESP32"

In case of implementing a network LoRa some recommendations and considerations ..

LoRa works on an open spectrum is free to license specifically the ISM bands "Industrial, scientific and medical (ISM) radio bands"

they are for radiofrequency that are not telecommunications, such as example cellular telephony, police radio etc.

There is an international regulation, but you should also know the regulations for your country regarding LoRa.

To avoid conflicts and generate an order to each country, zone, region or continent has been assigned a frequency

in my case I am in South America the frequency assigned is 915.0 MHz, in my websites this is the most detailed documentation.

Comparison between LoRa and Other Inhalambricas Technologies

LoRa is long-range, low battery consumption, portable and a low-cost technology.

A few months ago I received 2 LoRa RFM95 modules from HopeRF Electronics

Be careful not to be charged with static energy, they could damage the modules.

Communication by Bus SPI to 3.3v

Important to buy the modules according to the frequencies assigned to your country.

in my case 915.0 MHz, it is demarcated in the module PCB

Comparing in size with an ESP8266, the RFM modules are small ..

As mentioned above, correctly select the module with the correct frequency assigned to your country

these modules are very popular there are shield for Arduino and they are cheap .. well maybe they should not the maximum distance but they are good ..

It has 6 GPIO, which the module uses as outputs or inputs for events and / or LoRa interruptions.

Technically these modems are sent parameters or configurations by SPI.

"PinOUT"

Important! works at 3.3v, for arduinos at 5v use converters at 3.3v

For a long time I wanted to perform tests with LoRa, it is perfect for sending sensor data

Well I hope that this little introduction, I started it in LoRa ..

In the next Tutorials we will make ESP8266 connections and later we will connect with the platform "The Things Network" implementing "LoRAWAN" ....

Another advantage of LoRa, the modules do not require to pair, associate or scan them. Technically they are in the same frequency and / or encryption key, send and receive.

Complete documentation in the description of the video .. greetings

Galette bretonne au chocolat | ASMR - Duration: 9:39.

Everybody Cacao〜!∴∵ゞ(´ω`*)

This time is Galette bretonne au chocolat. It is a suble of thick crisp fabric.

"Galette" is a generic name for circular flat baked goods.

Using butter and microwave etc, soften it like mayonnaise.

Put powder sugar and salt one knob and mix well. It is better to shake powder sugar.

Let's squash the lump of sugar.

Egg separates egg white and egg yolk, only use egg yolk

Ugh!

It always happens〜( ´・ω・`)

Oh my god! Egg stock is...

There was one for baseball ε-(´・`)foo

We separate it into egg white and egg yolk.

Dissolve egg yolk and use 15 g.

MS ~ LL size egg, it was about one piece.

Mix well.

Sift the powders together.

Mix as it cuts, to reduce stickiness.

The dough will be put together. Put the lap on the dough and put it in the refrigerator. (σ´ω`)σ♪

I cut the lap a little and reused it when I extended the dough.

I will extend the dough.

Using a 10 mm thick acrylic ruler, make the fabric 10 mm thick.

It may be quick if you cool down after dough. However, after leaving the dough, I think that the dough will become more familiar and stable.

Well, once you extend the dough again cool it in the refrigerator for about 2 hours.

Because this fabric is soft, it may not be beautifully removed from the mold unless it is cooled.

Make egg liquid to be spread on the surface of Galette. First, we separate egg white and egg yolk.

Loosen egg white and make it easy to weigh.

Return half of egg white to egg yolk and mix.

Apply egg solution twice to the surface of Galette.

Once the egg solution is applied, dry it in a refrigerator.

Apply the egg solution again and dry again in the refrigerator.

Using a fork, put the line twice on the surface of Galette.

It is good to cross the three lines slightly from the middle.

This time the baking tool used the galette wheel case, but if you do not use it it may be better to make use of the mold etc.

As this dough spreads like melted when baked, the baking mold is necessary.

Galette baked♪

It's good ☆(゚∇゚☆)

I will coat chocolate.

Melt and chop chocolate.

I will temper the black chocolate.

Melt the chocolate and make the temperature of chocolate itself around 45 - 50 ° C.

Because it is black chocolate, lower it to about 25 ℃ and raise it to about 31 ℃ again and check.

It is OK if it hardens in 2 to 3 minutes and fat bloom does not come out.

In order to keep chocolate warm, I used a thermo heater for tropical fish. Warm chocolate at 31 ~ 32 ℃.

I will put chocolate on Galette.

I tried painting a little like spring like a little.

Freeze dry Franboise

Nice cacao!

It's only cacao. But it's cacao.

Let's eat♪

Well, It looks tasty.

It crumpled and it melted away. It is sweet and soft with a low dough ♪ very delicious.

Chocolate with a little attached was a good accent, giving a difference in taste and texture, making it more delicious.

For the flakes on the outside only the mangoes understood the difference.After all it was drown out with chocolate and it became important to appearance.

It's very delicious σ(´~`*)

Thank you for the meal♪

The remaining chocolate in the coating was put in a mold, and chocolate was born again as a delicious chocolate.

Healthy Narcissism. - Duration: 7:24.

Hi all.

Here we are back again and the child-self in me has been just pressing me to put him

on the screen so here goes: Spring is here, the grass has rise, I wonder where the birdies

is?

All the birds is on the wing.

My word that's absurd, all the wings is on the bird.

I gave him his chance and let's focus on what it is that he said.

Spring is almost here.

The spring festivals are going to be celebrated, are being celebrated and the main two religions

in this country: the Judeo-Christian tradition is in focus.

Passover and Easter and the reason I focus on them is because they impact on you.

Its holiday season and the holiday for many means food and indulgence.

What I've been talking about for the longest time is self-love, confidence, feeling good

about it and asking a question.

The question is: If it makes me feel so good to lose the weight, to be happy about the

change in my body, to feel the growing confidence in the fact that I am taking over my decisions

and then come the holidays and I find I break down.

I compromise, I do things that I know after the fact are going to make me feel bad and

yet they happen and I do feel bad and I am unhappy and I make excuses and I rationalize

why I did what it is that I did and then I have to come back to the weight loss office.

There's the sign Accu Weight-loss, The Bead Diet 15 pounds minimum in one month.

Why go through all of that?

Why not plan and prepare and enjoy?

If I have a plan, if that plan is rational and if I'm willing to stick by my plan then

I'm going to show self-love.

I don't know about you but I know that when I do things which say that I love me and particularly

when I follow through behaviorally I feel incredibly good.

I love being me and me who was being loved by me seems to prosper from it.

Now what it is that I'm saying: These holidays are celebratory.

Celebratory means food but it also means that other people are going to be sharing this

with me and they may not be thinking in the same way that I'm thinking but if I go in

prepared to be responsive and not reactive.

Remember the rule: act you're number one, react you can't be more than coming in second

place.

I love to win, it feels good, I know I can't win all the time but if I win even occasionally

each time that I act in favor of me, to love me, I know I have a chance of succeeding.

If I'm always reacting then my confidence is attacked by the fact that I'm not number

one almost ever and therefore my expectations are reduced.

Limit your indulgences.

How do you do that?

No where you're going, have a sense of what's going to be happening and set a limit as to

what you're going to do.

What your behavior is going to be and if someone says: Come on let go, enjoy yourself.

Look at them and say: You have no idea how good it feels for me to be controlling myself

right now because to tell you the truth I really want that indulgence but I don't want

to feel the guilt and remorse that I'll have after.

I'm not excited and happy about not having it now but I know darn well I'm going to feel

good about it after.

Have a plan, think about the plan, put it into action and verbalize with people.

Speak out but don't speak out negatively.

Tell them how you feel and why you're behaving in the way in which you're behaving and

add how good it makes you feel.

There's a way of being a narcissist and doing it in a healthy manner.

Good talking to you.

WINDOWS at NIGHT - An animated essay - Duration: 3:21.

I collect symbolic imagery

like a lepidopterist collects butterflies -

And Berlin, has the best specimen of windows

that I have ever seen.

This isn't an architectural observation -

It's a confluence, of time and place.

They only happen in Winter,

when complete darkness by evening rush-hour

brings them on, in chorus.

Humble apartment blocks transform -

they become - bright display cases,

tropical aquariums

Incubators for alien babies.

But if it was just a visual effect -

why did they move me so?

I knew that they stood for something else -

So, I drew windows. But in my paintings -

Windows were always just a frame for a person.

I saw this as incorrect -

Because this was not the way I experienced windows.

But when I drew no people at all,

the way I saw them when I took long walks on cold evenings,

I couldn't connect.

I didn't get the symbolism.

It was only a short while ago that I understood.

I'd been gone on a trip

When I returned in the evening, approaching my home,

I KNEW something was wrong

he police had evacuated our block

There'd been a serious flood

Those dark windows were a sour, off-key note.

Without the lights,

the house felt dead

And I understood then

I, the consummate introvert,

loved lit windows not because of their colours

or because they looked like nocturnal butterflies.

My art had reached the truth long before I had.

Lit windows signified people -

they filled me with joy, BECAUSE they signified people.

So in my art, I always had a single figure among windows.

A person emphasised.

A self, amongst many selves.

What I was forgetting was, on those cold walks -

it was never just the windows.

It was the windows, and myself.

Your story is made up of the places you focus

your attention on.

Like looking up through a lace of trees to see the moon.

Symbols are the very real lace of the relationships between things

They are all just behind the clear glass

longing to play with you.

Inspiration wipes away the condensation with her sleeve

and waits patiently. All you have to do -

is lean in, and look.

CORT GB35A - доступная пятиструнная бас-гитара - Duration: 6:10.

Hi everyone! You are on the PopMusic channel,

my name is Dmitry and today we'll review the bass guitar CORT GB35A.

The body of this bass guitar is made of agathis, the neck is made of maple, the fingerboard - rosewood, 22 frets.

The neck is bolted on four bolts.

The bass guitar has active electronics.

Two pickups: the single in the neck position and the humbucker in the bridge position.

There is a volume knob with push-pull switch

to convert between active and passive modes.

A balance of pickups and a 2-band equalizer,

high and low cut off.

Let's listen to each pickup of this bass guitar.

Starting from the neck pickup.

How does the active/passive conversation work?

The equalizer turns off in the passive mode and turns on in the active mode.

You can use it in practice in a very interesting way.

As example, if you are playing in passive mode,

you can increase the low frequencies in advance, and turn on the active mode by this switch,

so the equalizer will turn on and you'll get low frequencies boost.

And now let's listen to the bass guitar with the overdrive.

This bass guitar is close to Jazzbass in sound,

but due to the presence of humbucker, you can also achieve a sound close to Music Man,

this makes it an interesting and universal instrument.

Because of the affordable price category of this instrument, I want to note that

the guitar is well-done, the fifth string, С,

sounds mellow, that's very rare for such instruments.

Introduction LoRa & Module RFM95 Hoperf Electronics - Introduccion LoRa & Modulo RFM95 : PDAControl - Duration: 8:22.

In this opportunity we will make a small Introduction to the LPWAN networks based on LoRa and we will characterize the Module RFM95

Let's look for images about LoRa to get the idea ...

But .. What is LoRa ??

LoRa is a long-range radio technology in English "Lo ng- Ra nge" developed by SEMTECH its main features are ...

1. Its spread spectrum modulation allows a significantly greater range than other Max 15-20Km technologies.

2. High sensitivity (-168dB) combined with high immunity to interference.

3. Low Consumption (up to 10 years with a battery, good depends on certain characteristics).

4. Low data transfer (up to 255 bytes).

Let's first clarify that "LoRa" and "LoRaWAN" are not the same:

LoRa is the physical layer or in simple words is the modulation, the modem or radio, the hardware.

LoRaWAN is the protocol of the network or the architecture, securities and connections that work on LoRa.

lora-alliance.org is an open organization initiated by industrial leaders to standardize LPWAN networks

The idea is to position LoRaWAN in Industrial, IoT and M2M applications.

There are videos and complete documentation about LoRa and especially LoRaWAN

Let's look at some possible architectures ..

There are LoRa devices or Nodes, possibly Sensors and / or Actuators

Since it is for IoT applications, there are "Gateway" that receive information from the nodes.

The "Gateway" technically converts LoRa to Ethernet protocol and is already WLAN / LAN / 3G / 4G ... LoRaWAN already has a lot implemented

Let's look at the "LoRa" Hardware available ..

You can buy only the Radio ..

There are LoRa Modules of all price and quality which is reflected in the Final application ..

There are "shields" and integrations with platforms and microcontrollers "Pic, Arduino, ESP8266, Raspberry pi and ESP32"

In case of implementing a network LoRa some recommendations and considerations ..

LoRa works on an open spectrum is free to license specifically the ISM bands "Industrial, scientific and medical (ISM) radio bands"

they are for radiofrequency that are not telecommunications, such as example cellular telephony, police radio etc.

There is an international regulation, but you should also know the regulations for your country regarding LoRa.

To avoid conflicts and generate an order to each country, zone, region or continent has been assigned a frequency

in my case I am in South America the frequency assigned is 915.0 MHz, in my websites this is the most detailed documentation.

Comparison between LoRa and Other Inhalambricas Technologies

LoRa is long-range, low battery consumption, portable and a low-cost technology.

A few months ago I received 2 LoRa RFM95 modules from HopeRF Electronics

Be careful not to be charged with static energy, they could damage the modules.

Communication by Bus SPI to 3.3v

Important to buy the modules according to the frequencies assigned to your country.

in my case 915.0 MHz, it is demarcated in the module PCB

Comparing in size with an ESP8266, the RFM modules are small ..

As mentioned above, correctly select the module with the correct frequency assigned to your country

these modules are very popular there are shield for Arduino and they are cheap .. well maybe they should not the maximum distance but they are good ..

It has 6 GPIO, which the module uses as outputs or inputs for events and / or LoRa interruptions.

Technically these modems are sent parameters or configurations by SPI.

"PinOUT"

Important! works at 3.3v, for arduinos at 5v use converters at 3.3v

For a long time I wanted to perform tests with LoRa, it is perfect for sending sensor data

Well I hope that this little introduction, I started it in LoRa ..

In the next Tutorials we will make ESP8266 connections and later we will connect with the platform "The Things Network" implementing "LoRAWAN" ....

Another advantage of LoRa, the modules do not require to pair, associate or scan them. Technically they are in the same frequency and / or encryption key, send and receive.
