Acelerador no Stepper! E Simulação em CAD, Carne Fumada num Apartamento(!), Curso se Carpintaria, Raspberry Pi no Smartphone, e façam um Helicóptero em casa!

Era chato não poder usar os Steppers, ou motores passo-a-passo, para o que queiram, e com aceleração e desaceleração, mas agora...

Já podem!

Sim podem finalmente usar aquele monte de Motores que recuperaram das Impressoras, usando um Arduino...

É bom!

Arduino : How to Control a Stepper Motor With Potentiometer

MertArduino in arduino 

This instructable is the written version of my "Arduino : How To Control a Stepper Motor with Potentiometer" YouTube video that I've uploaded recently. I strongly recommend you to check it out.

First, you should see the following Instructable:

How to Control a Stepper Motor With L293D Motor Driver

This tutorial is all about tuning the speed of a stepper motor using a potentiometer. The idea is to up or down the speed of a stepper motor using with analog read. Theoretically analog input to a digital output, we're going to use this concept to control the speed of a running stepper motor.

3 new features in CAD software for 3D printing material testing 

One major issue while dealing with digital manufacturing is the ability to test your 3D printed model. Thanks to a better understanding of materials, new features in computer aided design software allow you to improve this process. Here is a list of a few new functionalities in CAD software, based on generative design implementations in molding simulation, structure optimization or mechanical behaviors. Enhance your CAD experience in 2017!

É só facilidades.

Smoking in an apartmentjuniortan in bbq-and-grilling 

I live in a country where 82% of people live in apartments, where the concept of having a backyard or any space to smoke meat is most uncommon. So I set out to try and see if it is possible to do this indoors without involving fire-fighters, hazmat suits or N95 masks. As it turns out, stove-top smoking is not that unusual in many countries, but looking for the necessary equipment here would definitely be challenging. Hence this instructable, and hopefully more foolhardy souls can give it a try too, that smoking meat in relatively confined spaces is not impossible...
This instructable will NOT be covering how to dress or marinade the meat; I use various rubs and mustards myself, here I will focus just on the smoking part.

Podem usar o vosso Tablet como o Écran do vosso Raspberry Pi, eis uma grande ajuda para programarem sem entraves, pois não precisam do Monitor específico para o Raspi:

Use your tablet as Raspberry Pi screen

pinchan in raspberry-pi 

You need a certain type of monitor to use Raspberry Pi. Most of people do not have a monitor specifically for his/her Raspberry Pi. By taking this method, you can make your tablet or smartphone a screen for your Raspberry Pi. This will increase your productivity when you work with Raspberry Pi since you don't have to connect it with a PC screen.

Note that this technique works only when your Raspberry Pi and tablet/smartphone are connected to a same WiFi network.

For the detailed procedure, please refer to my blog.

Visitem primeiro o link que têem aqui, que essa página tem Linksque vão dar à página dos Planos, informa sobre como aprender a voar num Helicóptero e etc.

Ultralight Helicoptersadmin 

All About Ultralight HelicoptersMany have said that ultralight helicopters are the ultimate form of ultralight flight. Fast, nimble, and able to go almost anywhere, lightweight helicopters are also a more economical way to get into flying helis. Plans can be bought very cheaply on the internet. Kits are available for purchase, but typically cost more than building one from scratch from plans.
