Arduino Launches New Affordable Nano Microcontroller BoardsHanna Watkin
Arduino is the Italian open-source computer hardware and software company announced a new family of affordable, microcontroller boards at last weekend’s Maker Faire Bay Area 2019.
“The new Nanos are for those millions of makers who love using the Arduino IDE for its simplicity and open source aspect, but just want a great value, small and powerful board they can trust for their compact projects,” said Massimo Banzi, co-founder of the Arduino project.
The company’s press release explains that these boards offer high quality and reliability, with a cheaper price tag. The microcontroller boards are also compatible with classic Arduino boards and boast low energy consumption. They’re also equipped with powerful processors.

O FreeCad é a melhor opção para quem quer desenhar os seus Objectos 3D, e aqui vai um simpático Tutorial para aprenderem como dominar o Programa:
2019 FreeCAD Tutorial for 3D Printing – 5 Easy LessonsRocío Jaimes GutierrezWelcome to our FreeCAD tutorial for 3D printing. FreeCAD is a 3D parametric modeler, designed to create and customize real-life objects. Its beauty lies on the easiness to modify your designs, together with the open-source principle, and of course, being for free.In this 5-lesson FreeCAD tutorial, you will learn the basic commands and tools to visualize your ideas on screen for 3D printing. We will construct a seemingly simple object – step by step. After each instruction, you will find pictures highlighting the steps. By the end of this tutorial, you will be ready to print your first self-constructed CAD model.
Ora aqui está um Kickstarter a apoiar, um braço-robot OPEN-SOURCE!
Dito de outra maneira, CNC para o Povo!
Evezor: Open Source SCARA Robot ArmJeremy S. Cook
Per this project’s Kickstarter video seen below, when 3D printing first jumped came into the mainstream, many people thought they could now make anything they wanted, perhaps even many of them to sell with no human interaction. While true in some sense, these machines do require human intervention between prints, and can take a very long time to produce useful parts. Additionally, some designs may require a different tool, such as a laser cutter or CNC router. That, of course, means more space and money, and still there is the issue of machine tending.

O programa SCAD tem muitos aderentes, por isso, podem aprender como transformar aqueles Sólidos criados em relações Matemáticas, em Objectos impresso em 3D:
SCAD to STL – How to Convert SCAD Files to STLBenjamin Goldschmidt
SCAD and STL files are two common file types for 3D design applications. SCAD stands for “Solid Computer Aided Design”, and the file format is used to describe 3D objects. It was pioneered by a software called “OpenSCAD,” which is a free CAD software for designing 3D objects. STL stands for “stereolithography” and is a popular file type to use with slicers for 3D printing.
The main difference between these two file types is in the way the models are described in code. In STL files, the 3D model is created using a “tiled” set of triangles along the surface of the object. This creates a fully 3D object. In contrast, SCAD files design an object using mathematical relationships. For example, a cube-like object can be described using its length, width, and height. This type of design can be useful for printing objects such as fractal art on objects.
Because the geometry used by STL files is more capable of conforming to complex designs, you may find you want to convert SCAD to STL. Lucky for you, there are two really easy ways to do this.

Arduino Learner Kit (Open Source)taifur
If you are a beginner in Arduino World and going to learn Arduino having some hands-on experience this Instructables and this Kit is for you. This Kit is also a good choice for the teachers who like to teach Arduino to their students in an easy way.
If you want to learn Arduino you should include the following topics:
Digital Output:
Controlling multiple LEDs using Arduino
Generating Tone using Buzzer
Digital Input:
Interfacing button switch using Arduino
Interfacing DHT11 Sensor Using Arduino
Analog Input:
Reading Analog data from a potentiometer
Interfacing LM35 temperature sensor using Arduino
Analog Output (using PWM):
Generating multiple colors using the RGB LED.
SPI Communication:
Interfacing 74HC595 Shift Registerwith Arduino
Interfacing MAX7219CNG with Arduino for driving DOT Matrix display or multiple seven segment display using only 3 pins of Arduino.
I2C Communication:
Reading date and time from DS1307 real time clock
UART Communication:
Interfacing GROVE GPS and Bluetooth Module with Arduino
Display Interfacing:
Driving 16 X 2 Character LCD display using Arduino
Multiplexing:
Driving multiple seven segment display using a minimum number of Arduino pins.
You will be wondering to know that the Kit is designed to experiment with all the above-mentioned topics. So, it can be an Ideal Learner Kit for learning Arduino Programming.
[The Kit includes onboard 6 Green LED, 1 RGB LED, 1 Potentiometer, 1 LM35 Sensor, 1 DHT11 Sensor, 4 Button Switch, 4 Seven Segment Display, 1 8X8 Dot Matrix Display, 1 MAX7219CNG IC, 1 74HC595 Shift Register, 1 Buzzer, 1 16X2 LCD display, 1 DS1307 RTC, 3 Grove Universal Connector.]
No more separate shield or module, no more disgusting wiring on the way of learning Arduino.
