Development boards, Single-Board Computers (SBCs) and Single-Board Microcontrollers (SBMs) integrating sensors and communication technologies have become a very popular and interesting solution in the last decade. They are of interest for their simplicity, versatility, adaptability, ease of use and prototyping, which allow them to serve as a starting point for projects and as reference for all kinds of designs. In this sense, there are innumerable applications integrating sensors and communication technologies where they are increasingly used, including robotics, domotics, testing and measurement, Do-It-Yourself (DIY) projects, Internet of Things (IoT) devices in the home or workplace and science, technology, engineering, educational and also academic world for STEAM (Science, Technology, Engineering and Mathematics) skills. The interest in single-board architectures and their applications have caused that all electronics manufacturers currently develop low-cost single board platform solutions. In this paper we realized an analysis of the most important topics related with single-board architectures integrating sensors. We analyze the most popular platforms based on characteristics as: cost, processing capacity, integrated processing technology and open-source license, as well as power consumption (mA@V), reliability (%), programming flexibility, support availability and electronics utilities. For evaluation, an experimental framework has been designed and implemented with six sensors (temperature, humidity, CO2/TVOC, pressure, ambient light and CO) and different data storage and monitoring options: locally on a μSD (Micro Secure Digital), on a Cloud Server, on a Web Server or on a Mobile Application.

Memorable Event

STEMroller events disrupt stereotypes surrounding STEM professionals within a neglected space in science communication; a sports hall. Roller derby inspired STEMroller, both the do-it-yourself culture and creating a space for women and genderqueer people to be themselves. Over 100 female and non-binary STEM professionals volunteered to put this event together for students aged 11–19. STEMroller includes networking with people from over 30 science, technology engineering and mathematics industries, watching roller derby and trying it out — albeit in socks not on wheels. STEMroller uses a pool of engaged volunteers to create a unique and memorable event. Feedback after the event was hugely positive.

The increasing demand for fast and on-site information has generated great interest in developing simple and portable analytical devices that provide reliable responses. Electroanalytical devices fit perfectly with these purposes because of their ease of use, low cost and facility of miniaturization. Moreover, the growing interest in the construction of do-it-yourself electronic devices has spread the use of common and mass-produced materials for the development of analytical devices. In this context, it is presented here the use of gold-plated pins, from standard connections, and stainless-steel pins, from needlework, as electrodes in (bio)electroanalytical platforms. Three different analytical platforms combining those pins with paper, transparency sheets or micropipette tips were constructed and applied in food and environmental analyses: glucose determination in beverages and surfactant analysis in water.

In the last decade, Australian SMEs are steadily becoming more digitally engaged, but they still face issues and barriers to fully adopt Industry 4.0 (I4.0). Among the tools that I4.0 encompasses, digital twin (DT) and digital thread (DTH) technologies hold significant interest and value. Some of the challenges are the lack of expertise in developing the communication framework required for data collection, processing, and storing; concerns about data and cyber security; lack of knowledge of the digitization and visualisation of data; and value generation for businesses from the data. This article aims to demonstrate the feasibility of DT implementation for small and medium-sized enterprises (SMEs) by developing a framework based on simple and low-cost solutions and providing insight and guidance to overcome technological barriers. To do so, this paper first outlines the theoretical framework and its components, and subsequently discusses a simplified and generalised DT model of a real-world physical asset that demonstrates how these components function, how they are integrated and how they interact with each other. An experimental scenario is presented to transform data harvested from a resistance temperature detector sensor connected with a WAGO 750-8102 Programmable Logic Controller for data storage and analysis, predictive simulation and modelling. Our results demonstrate that sensor data could be readily integrated from Internet-of-Things (IoT) devices and enabling DT technologies, where users could view real time data and key performance indicators (KPIs) in the form of a 3D model. Data from both the sensor and 3D model are viewable in a comprehensive history log through a database. Via this technological demonstration, we provide several recommendations on software, hardware, and expertise that SMEs may adopt to assist with their DT implementations.

Contrast Mechanisms

The near-field optical interaction between a sharp probe and a sample of interest can be exploited to image, spectroscopically probe, or modify surfaces at a resolution (currently down to ~12 nm with visible light) well beyond the diffraction limited response of traditional far-field systems. The resulting technique, near-field scanning optical microscopy (NSOM), still retains many of the attractive features of conventional optics, including non-invasiveness, low cost, reliability, and ease of use. Most importantly, NSOM takes advantage of the numerous and powerful contrast mechanisms and associated sample preparation procedures developed for optical microscopy over the last three centuries.Several applications have been investigated to demonstrate the versatility arising from these contrast mechanisms. For example, polarization contrast has been coupled with near-field surface modification capabilities to image and record domains in thin-film magneto-optic materials (Fig. 1). This might form the basis for a new method of ultra-high density optical data storage, or could be used in a study of domain wall energetics in magnetic systems.In the biological arena, NSOM has been used to image fluorescently labeled cytoskeletal actin in fixed mouse fibroblast cells (Fig. 2), and applied in a study of the actin organization within wound healing protrusions. The resulting images were also compared to topographic data arising from the shear force mechanism which regulates the probe-to-sample separation.

Teaching Learning

STEAM is an innovative teaching-learning process based on Science, Technology, Engineering, Arts and Maths competences. Accordingly with this new approach, a team of Fine Arts and Management professors are currently leading an innovative project based on "Applying STEAM Strategies in the Social Sciences and Arts Areas”. The objective is to establish links between the different STEAM competences -science, technology, engineering, art and mathematics- as a common element in classrooms, enhancing technological training. This new approach motivates students and connects teaching to present society’s needs. In this paper we present an analysis of a teaching experience outside the classroom, developed at the Museu de Belles Arts in Valencia (Spain). In this activity, several tools that use technology with which the students are familiar are used, in which is called “BYOD” (Bring Your Own Device). In this case we analyze the use of the photography as a teaching tool. Some of the characteristics of the activity include free time and different spaces at the museum, DIY -Do it Yourself-, cooperative teamwork, peer learning, integration of theory into practice, flexible thinking and analytical skills. The activity looks to motivate them through gamification. After data collection, debriefing is used for integrating results.

Abstract:Controlling environmental conditions is an important component in preserving archives and manuscripts, with building design and HVAC systems widely used to achieve the desired conditions. One tool used for monitoring HVAC systems is the datalogger, which stores data such as temperature and relative humidity. As such devices can be costly and inflexible, this work explores the creation of a do-it-yourself datalogger and compares its accuracy, reliability, extensibility, cost, and ease of use against a popular commercial device. Findings suggest that organizations with sufficiently technology-savvy staff can construct and employ a DIY monitor for approximately one-quarter the price of commercial options, although costs may rise over time for support and maintenance of such systems.
