Electronic Engineering undergraduates are increasingly interested in final-year individual projects that involve brain–computer interfacing. This paper outlines the challenges of resourcing these types of medical instrumentation projects and describes the adoption of the open source OpenEEG electroencephalography platform in final-year undergraduat...

... OpenEEG design. At the time of writing, the populated analog and digital boards cost approximately $80 and $53, respectively. Electrodes, cables, connectors and housings were purchased separately. Abrasive skin prepping gel and conductive EEG paste were also required. This made the final cost of each complete system approximately $300. Fig . 2 shows the Olimex analog and digital boards. The analog board amplifies and filters the microvolt EEG signal and a right-leg driver reduces common mode interference, primarily from 50Hz UK (60Hz USA) mains hum, by subtraction. The digital board uses the Atmel ATmega8 microcontroller and outputs 6 channel EEG packets via an RS-232 ...

In this paper, a set of digital artifacts related to simple examples of structural engineering are presented. The artifacts are real-time applications and visualizations of typical problems students from the architecture, engineering, and construction (AEC) schools are acquainted with. The real-time nature of the examples allow a high level of interaction between humans and the classic visualization of results, namely, bending and shear force diagrams, internal stresses distributions, and contour plots. These artifacts may provide in AEC a twofold educational target: (i) for users, to provide visual understanding in real time of typical problems that must be understood in classic lectures of structural engineering; (ii) for developers, to provide meaningful applications of applied digital fabrication using sensors, microcontrollers, and GUI's and their potential in the development of tools related to Structural Health Monitoring (SHM) and the Internet of Things (IoT) among students of the AEC sector.
