The New Shop Class

The New Shop Class connects the worlds of the maker and hacker with that of the scientist and engineer.

If you are a parent or educator or a budding maker yourself, and you feel overwhelmed with all of the possible technologies, this book will get you started with clear discussions of what open source technologies like 3D Printers can really do in the right hands.

Written by real "rocket scientist" Joan Horvath, author of Mastering 3D Printing, and 3D Printing expert Rich Cameron, The New Shop Class is a friendly, down-to-earth chat about how hands-on making things can lead to a science career.

Get practical suggestions about how to use technologies like 3D printing, Arduino, and simple electronics. Learn how to stay a step ahead of the young makers in your life and how to encourage them in maker activities. Discover how engineers and scientists got their start, and how their mindsets mirror that of the maker.

Renishaw, HiETA & nTopology Support Cobra Aero in the Design, Development and Production of a Novel UAV Engine

Cobra Aero, a successful producer of two-stroke engines for UAV applications approached Renishaw to understand how they could incorporate additive manufacturing into their existing manufacturing portfolio.

Cobra had a vision for the use of metal Additive Manufacturing (AM) in their business, and enlisted additional help from HiETA and nTopology to help drive the development of an innovative engine design.

Leveraging the design opportunities of AM and the expertise of the partners involved, Cobra have devised a pioneering and extremely performant new engine design.

Moreover, Cobra have explored the applications space including production of tooling, complex componentry and highly customized components in their sister motorcycle business, Cobra Moto.

Primary Topics: • Design for Manufacture • Aerospace Design • Complex Structures for Heat Exchange • Product Innovation and Testing Speaker: Kevin Brigden Additive Applications Engineer, Renishaw

Kevin has a master's degree in engineering with honors in motorsports engineering from the University of Central Lancashire, England. A member of a team of technical specialists, he brings a skill-set centered in computer-aided engineering (CAE) including computer-aided design (CAD), finite element analysis (FEA) and computational fluid dynamics (CFD). During Kevin's time with Renishaw, he has led and consulted on numerous design projects in collaboration with partners and customers from aerospace, automotive, space and defense and medical engineering. Kevin is at the forefront of the design for additive manufacture (DfAM) movement, with many of his characteristic and innovative designs widely recognized and imitated.

A plug-and-play Hyperspectral Imaging Sensor using low-cost equipment

HSIs (Hyperspectral Imaging Sensors) obtain spectral information from an object, and they are used to solve problems in Remote Sensing, Food Analysis, Precision Agriculture, and others.

This paper took advantage of modern high-resolution cameras, electronics, and optics to develop a robust, low-cost, and easy to assemble HSI device. This device could be used to evaluate new algorithms for hyperspectral image analysis and explore its feasibility to develop new applications on a low-budget.

It weighs up to 300 g, detects wavelengths from 400 nm–1052 nm, and generates up to 315 different wavebands with a spectral resolution up to 2.0698 nm. Its spatial resolution of 116 × 110 pixels works for many applications. Furthermore, with only 2% of the cost of commercial HSI devices with similar characteristics, it has shown high spectral accuracy in controlled light conditions as well as ambient light conditions.

Unlike related works, the proposed HSI system includes a framework to build the proposed HSI from scratch. This framework decreases the complexity of building an HSI device as well as the processing time. It contains every needed 3D model, a calibration method, the image acquisition software, and the methodology to build and calibrate the proposed HSI device. Therefore, the proposed HSI system is portable, reusable, and lightweight.

Development of a 3D-printed device evaluating the aerodynamic performance of rotary wings

Applications for remotely operated rotary wing aerial vehicles, hereafter referred to as drones, are rapidly expanding in scope and such aircraft may soon become an integral part of everyday life as well as a source of innovation.

However, it is quite difficult to improve drone flight performance and reduce development costs because performance optimization depends strongly on the intended application.

As a result, drones are currently developed by trial and error using various rotary wing shapes. In this study, a device for evaluating the aerodynamic performance of rotary wings is proposed.

The authors consider it likely that the proposed device will be useful for various drone-related applications in addition to facilitating drone development because it is inexpensive to produce and can eliminate the need for large expensive laboratory equipment such as wind tunnels when performing flight characteristic evaluations.

UAV Photogrammetry for topographic monitoring of coastal areas

Coastal areas suffer degradation due to the action of the sea and other natural and human-induced causes.

Topographical changes in beaches and sand dunes need to be assessed, both after severe events and on a regular basis, to build models that can predict the evolution of these natural environments.

This is an important application for airborne Laser Imaging Detection and Ranging (LIDAR) and conventional photogrammetry is also being used for regular monitoring programs of sensitive coastal areas.

This paper analyses the use of UAVs (Unmanned Aerial Vehicles) to map and monitor sand dunes and beaches. A very light plane equipped with a very cheap, non-metric camera was used to acquire images with ground resolutions better than 5 cm.

The Agisoft Photoscan software was used to orientate the images, extract point clouds, build a digital surface model and produce orthoimage mosaics. The processing, which includes automatic aerial triangulation with camera calibration and subsequent model generation, was mostly automated.

To achieve the best positional accuracy for the whole process, signalised ground control points were surveyed with a differential GPS (Ground Positioning System) receiver. Two very sensitive test areas on the Portuguese northwest coast were analysed.

Detailed DSMs were obtained with 10 cm grid spacing and vertical accuracy (RMS) ranging from 3.5 to 5.0 cm, which is very similar to the image ground resolution (3.2–4.5 cm). Where possible to assess, the planimetric accuracy of the orthoimage mosaics was found to be subpixel.

Within the regular coastal monitoring programme being carried out in the region, UAVs can replace many of the conventional flights, with considerable gains in the cost of the data acquisition and without any loss in the quality of topographic and aerial imagery data.

UAVs for 3D mapping applications

Unmanned Aerial Vehicle (UAV) platforms are nowadays a valuable source of data for inspection, surveillance, mapping and 3D modeling issues.

As UAVs can be considered as a low cost alternative to the classical manned aerial photogrammetry, new applications in the short- and close-range domain are introduced.

Rotary or fixed wing UAVs, capable of performing the photogrammetric data acquisition with amateur or SLR digital cameras, can fly in manual, semi automated and autonomous modes.

Following a typical photogrammetric workflow, 3D results like Digital Surface or Terrain Models (DTM/DSM), contours, textured 3D models, vector information, etc. can be produced, even on large areas.

This paper explore the use of UAV for Geomatics applications, giving an interesting overview of different UAV platforms and case studies.
