Abstract In this paper, a simple and practical method to hookup between Pyboard and computer using MicroPython and MATLAB is presented. With the presented way, MATLAB can connect to Pyboard with virtual serial port (VSP). This process is performed with a virtual port, without using MATLAB toolbox in all versions of this software and control prototy...

Before the COVID-19 pandemic, open source hardware development grew steadily. However, the pandemic rapidly accelerated the global acceptance of open source hardware solutions. While open source software has long been vital in the ICT sector, this concept now extends to physical hardware production. Notably, the medical and energy fields have prominently embraced this shift, utilizing 3D printing to actualize open source designs. This study explores pre-pandemic Open Source Scientific practices, aiming to extract insights for a stronger future open source framework. Through an in-depth case study, we illuminate best practices, exemplary applications, and propose a framework for upcoming open source hardware projects. Additionally, this paper categorizes key areas of open source hardware innovation, outlining key sections and areas, thus offering a comprehensive view of the open source hardware landscape.
... This simplifies the framework implementation, as most people are familiar with MS Excel. MS Excel appears to be a ubiquitous tool for data analysis and does not appear to "intimidate" users the way that some more efficient computational tools, e.g., MATLAB, Python, may (e.g., [43][44][45]). As such, the authors felt that MS Excel would be most accessible for SMCB owner-operators. ...
Small and medium commercial buildings account for nearly half of the energy consumed by commercial buildings in the United States. While energy retrofits can significantly reduce building energy consumption, buildings’ owners often lack the capital and experience to perform detailed energy audits and retrofit assessments. The purpose of this paper is to introduce a low-investment, bottom-up and simplified methodology for identifying energy retrofit opportunities that benefit the owners of small and medium sized office buildings In particular, the paper addresses small and medium commercial buildings on a university campus as a proof-of-concept for other owner-operators that have small and medium commercial facilities in their portfolio. The methodology consists of an eight-step framework using publicly-available and simplified tools. While energy audits and retrofit opportunity assessments are not new, a low-cost methodology for owner-operators of small and medium commercial buildings to analyze energy consumption and identify retrofit opportunities represents a contribution to knowledge. A medium office building on a university campus in Arizona served as a case study to validate the methodology. The case study showed a maximum potential energy reduction of an estimated 50%, but the figure varies based on the types of retrofit (deep versus light), energy conservation measures selected and implemented, invested resources, and interactive effects between measures. This methodology is extensible to other owner-operators that have building utility data and would like to perform retrofit opportunity assessments themselves.

Monitoring systems are ubiquitous in many environmental science fields due to the technological advances in the last decades, which contributed to the migration from conventional to automated observing networks. However, the cost of acquisition and operation of sensor networks is still a limiting factor for their wide use. Under this scenario, low-cost and affordable open-source sensors and systems emerge as an alternative to research-grade instruments. To fulfill the quality requirements defined by international organizations, sensor calibration has to be performed and shall be considered as a basic requirement. Best monitoring practices including established quality control procedures should be implemented for gathering environmental data. With a focus on data gathering, this paper reviews basic concepts on open source technologies, calibration methods, quality control procedures, applications and trends, and possibilities for improving the hardware of low-cost and affordable systems.
