TRANSISTOR ELECTRONIC CIRCUIT

Hey, everybody,

We studied the transistor. Today, in order to understand how it works, we are going to create a circuit in Tinkercad that includes a transistor capable of giving way to a current, when another one is provided by the middle pin.

The assembly will be:

You can see the simulation HERE

The development is explained in the following tutorial:

Audio Edition with Audacity

In the first practice of audio edition with Audacity, we will...


1.Look at the program's user interface.

2.Record our voice.

3.Reduce the microphone noise

4.Insert a music track.

5.Use the auto duck effect

6.Fade out the end of the audio.

7.Finally, we will export the sound clip resulting from the edition and share it on the Internet

TRANSISTOR OPERATION

Today, I explain a little how a transistor works.

Mosfet or as we all know, switch; it is an electrically operated switch that allows a current flow, it is made of silicon.
These devices can act as a switch without moving parts, and their main function is amplification.
Doping is used to improve the conductivity of semiconductors.

HERE ARE SOME PICTURES THAT EXPLAIN A LITTLE BIT:

 










This are  two links of two videos that explains better the functions of a TRANSISTOR:

AUDIO GUIDE OF WASTE CONTAINERS AND TEST IT

Good afternoon

Today we are going to show you how to make an app with the free software app inventor that will serve us as an audio guide to recognize in which containers we should deposit the waste.


We will use:

• Buttons
• Images to cover the buttons
• The TexToSpeech resource

The design will be as follows:

The programming blocks for the operation of the app are:

Video of how was developed:

We test the app:

Now, I'm going to show you how to record a video from your mobile screen and then upload it to Youtube. For example to make a video like the one above:
These are the steps:

Some mobile devices have the predefined function to record the screen, in case you don't have it you should download a playStore app, there are many, I do well with AZ Recorder.
When you have downloaded it, to record your screen you must enter the app and then press the button on the camera, in 3 seconds it will start recording. It is a very simple app.
To end the video you must press the stop button, automatically the video will be saved in the gallery.
To upload it to Youtube, you must go to the gallery, press the send button, look for the Youtube icon and press it.
You will have to include a title and a description and then send it.
If you do not have a Youtube channel yet, you will be asked for the name you want to give to your channel.
The video will automatically be uploaded.
Both in the Youtube app of your mobile, and in the computer by entering www.youtube.com , you can manage the permissions of the video, change the title, delete it, etc.

FORMATTING A GOOGLE DOCUMENT

Good morning,

Today we are going to show you how to make a text, about a recipe, with a suitable format using Google's documents free tool.

The result is as follows:

You can download it at the following link:

This are the explanatory videos:

DIGITAL TRANSFORMATION

THIS IS A RESEARCH OF THIS VIDEO:

THIS VIDEO IS ABOUT A SPANISH DIITAL COMPANY,IS A GOOD VIDEO AND YO CAN LEARN A LOT OF IT.

If you are interested in knowing a little more or just imagine how life can be in the future, this video will enlarge several images about a better future and may clarify ideas for you.
Not only does it talk about change about society or simply about technology, it also shows you an idea about the world economy, it gives very broad images and I think this video is quite good.
Rather, it makes 4 references so that you have an idea of ​​how the world can be in the future, specifically speaking in 2030, 10 years from now, since things are still changing and increasing.

DESIGN OF A POSTER AND AN ADVERTISING LEAFLET

We have made a poster and an advertising leaflet from the following Internet image with no rights of use:

The poster edited at GIMP is as follows:

We have reduced the opacity of the background and then exported it to Google Slides.

In Google slides we have edited the brochure that finally has remained like this:
