Algo de muito útil, a lista dos tópicos dos fantásticos Vídeos de Dan Gelbart, um Génio da construcção de Protótipos, e penso TODOS os Engenhocas deviam ver os seus vídeos, para evitarem muita dor-de-cabeça, e fazerem muitas mais coisas do que pensam possíveis, com os meios de que dispôem:

Dan Gelbart : How to Build Stuff

Al-Hala

Dan Gelbart has an excellent and well-presented series on YouTube on machines and prototyping. It`s a short course on how to build stuff aimed at students, researchers and others who are not machinists by trade. It`s applicable to prototyping and limited production with enabling technology in 18 parts, which I’ve listed links to below. Note: the chapters were obviously shot out of sequence, as there is referral to `as we`ve seen before` when we have not. It`s not that bothersome.

How to Make a 18650 Li-ion Battery Pack!

Nematic!

18650 Li-ion cells are a great way to power Projects. Which provides a nominal voltage of 3.7V which is not sufficient for most of the application for let's say you want to power a BLDC motor with an ESC which requires 9V to start. So we need more voltage which can be achieved by connecting them in series. So in this tutorial, I will show you how you can make a 18650 Li-ion Battery Pack with a BMS circuit and all the things you need to know before you built one!

No último post, falei-vos de reciclagem de plástico, desta vez, vou falar-vos de Filamento 3D feito em pástico re-aproveitado:

WHAT WE DO

Spools of 3D printing filament are currently sourced from scratch, but CLP has developed technology to produce this material from everyday plastic waste instead. Compared to other recycling processes, making filament from plastic waste (think cups or packaging) is small-scale, quick, and low-energy. CLP will make 3D printing more sustainable by bringing high-quality recycled filament to a growing market of consumers.
CLP manufactures ready-to-use 3D printing filament spools in Irvine, CA. The current product line includes PS, and we are actively working towards ABS, PP, PLA, and PETG. CLP sources the waste plastic from local Materials Recovery Facilities as well as direct waste generators such as local resorts and university campuses.

Metamolds: Creating ideal 3D printed silicone molds faster and cheaper

Thomas

Silicone molding is an affordable production method that can allow you to make a series of identical objects for prototyping and functional testing. Until now, however, fabricating molds for casting complex objects required a lot of experience and also involved manual work, which made the process slow and expensive. Scientists at the Istituto di Scienza e Tecnologie dell'Informazione (ISTI-CNR) and the Institute of Science and Technology Austria (IST Austria) have developed a new tool for fabricating digital objects through reusable silicone molds. The tool automatically finds the best method to design the molds, and also delivers templates for so-called "metamolds": Rigid, 3D printed molds used to fabricate the optimized silicone molds.

Homemade CNC with 3D Printed Parts - Redesign

Leon van den Beukel

This is the second version of my DIY homemade CNC. It's a complete redesign because of some issues that I've had with the first one. The main issue with the first version was that the wooden Y axis was getting warped (by moisture I guess). Also the bearings were too small and the aluminium X rails were not strong enough to carry the weigth. That's why I've switched over to use 20mm x 20mm square steel tubes for both Y- and X axis. I've designed the 3D printed parts with Fusion 360 and used Inkscape for the Y axis drilling template. To control the machine I'm using an Arduino UNO with GRBL firmware and an Arduino CNC Shield. There are plenty of tutorials to find on how to connect and use it so I did not show it in the video. Here are some useful links:

Tinijet — Affordable Waterjet Cutting At Home

James Hobson

While laser cutting remains the dominant force for rapid prototyping anything made of plastic, MDF or wood, the real holy grail is the ability to cut metal — something most laser cutters are just not capable of.
In the industry, this is done using extremely high-powered laser cutters, plasma cutters, or water jet cutters. All of which are very pricey equipment for a hacker. Until now anyway. Introducing the Tinijet, the missing tool for affordable water jet cutting.
We first covered this project a few years ago when it was just a university research project called Hydro — it’s since evolved immensely, and will be available for sale very soon.

Step-by-step Guidance to Build a Drone From Scratch Using Ardupilot APM Navio2 Flight Controller

Simkaisheng

Ardupilot is a widely used open source unmanned vehicle autopilot software that is capable of performing many functions. Documentations and various sources have provided us with the basic knowledge of the setups and use each separate component of a drone but none has provided a detailed guide on how to put them together to build the drone’s hardware with guided steps of component setup and assembly from scratch, together with all necessary configuration and setups.
This article is written to combine all scattered information into one piece, to provide a step-by-step guidance from head to tail of how to build and assemble a quadcopter from scratch and how to perform all setup configurations required using the Navio2 Ardupilot flight controller. Other flight controllers from APM or others can also partly rely on this guide.

New products: Jrk G2 USB Motor Controllers with Feedback
Jan

After many months or years of work (depending on how you look at it), I am happy to introduce our newest motor controllers, the Jrk G2 USB Motor Controllers with Feedback, which we are releasing today in four power variants:

	Jrk G2 18v19	Jrk G2 24v13	Jrk G2 18v27	Jrk G2 24v21
Recommended max operating voltage:	24 V(1)	34 V(2)	24 V(1)	34 V(2)
Max nominal battery voltage:	18 V	28 V	18 V	28 V
Max continuous current (no additional cooling):	19 A	13 A	27 A	21 A
Dimensions:	1.4″ × 1.2″		1.7″ × 1.2″

The main purpose of the Jrk G2 family is to enable feedback-based control of DC brushed motors, simplifying closed-loop control of things like the position of an actuator. An example that is probably familiar to most of us is the common hobby servo that has an output shaft that can rotate to various positions as commanded over a simple interface. The Jrk motor controllers can be used for giant versions of those servos, and they can also be used in many other systems as long as you can somehow get feedback in the form of an analog voltage or a frequency. Analog voltage feedback is often easy to get from potentiometers that can serve as angle or position sensors.

Building the Google Open Nsynth Super
Andrew Back

A Raspberry Pi and machine learning powered instrument for generating new unique sounds that exist between different sounds.
NSynth (Neural Synthesizer) is a machine learning or “AI” algorithm from Google and collaborators that uses a deep neural network to learn the characteristics of sounds, and then to create a completely new sound based on these. More than simply mixing sounds it actually creates an entirely new sound using the acoustic qualities of the original sounds.
Open NSynth Super is an experimental physical interface for NSynth that is based around a Raspberry Pi, custom PCB and a simple laser-cut enclosure. It comes provided with turnkey O/S images that bundle preconfigured software and firmware, along with sets of example sounds — meaning that you don’t have to go through the extremely resource-intensive process of generating audio files in order to start experimenting with the synthesizer.
The PCB design, microcontroller firmware, software and enclosure design are all published under open source licences, meaning that anyone is free to build their own Open NSynth Super.

How to Repair STL Files with 3 Free STL Repair Software Tools
Dibya Chakravorty

Nothing is more frustrating than a 3D model that won’t print. STL files need to be watertight, have the right wall thickness and be properly optimized in order to be printable. Even the most experienced 3D designer will sometimes leave unprintable defects in the model. So you need software to repair your STL files.
If you have a broken STL file, your Slicer software will often warn you about the defects. But in the worst case, the slicer won’t complain at all. You will start printing as usual, spend time and money, and eventually land up with a failed print.
Another common scenario is when you try to upload an STL file in an online 3D printing service like i.materialize or Sculpteo, but get an error message saying that the file size is too big. In this case, you are dealing with a bloated STL file.
So what do you do in these situations? How do you repair STL files to get a printable version?
In this article, we introduce you to the best free software that can check your STL file for errors and also repair STL files automatically to produce a printable version.
