Mechanical occupancy counter – 3D printed

Limiting the number of people inside a shop or venue can help to maintain social distancing. This 3D printed mechanical counter can be placed in the doorway of a shop or other venue to count the number of people inside. The parts list, instructions, and 3D files to build your own counter are available here: Instructables […]

PCA in Teaching: Empowering the public with Lego-based solutions to real problems

Through the winter semester this year 2nd year students at the University have completed PCA projects as part of their core teaching. Focusing on developing designs that anyone can build at home to reduce their risk of transmission, Students were tasked to develop devices that removed the need for contact with surfaces and buttons on […]

New Publication in PLOS ONE – 3D Printing Negligible-cost Microfluidics

Negligible-cost microfluidic device fabrication using 3D-printed interconnecting channel scaffolds Available open access via PLOS One: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0245206 Harry, Robert Hughes and Andrea Diaz Gaxiola have together published work that demonstrates a fabrication method to produce negligible-cost microfluidic devices that can be combined using a system of inter-connecting joints. The method uses 3D printed scaffolds – produced […]

Social Distancing Glasses

Introduced as a measure to prevent the transmission of contagious disease, social distancing, or the act of maintaining a physical distance from others has inadvertently remained a restriction on society throughout this COVID-19 pandemic. Whilst many have followed guidance such as keeping 2m apart or complying with new and occasionally unclear distanced shopping systems, it’s […]

PCA Interaction Design @ La Tadeo – Challenge 3

The Product Design department at the Universidad Jorge Tadeo Lozano have been running PCA linked challenges as part of their Interaction Design course ‘Mediations’. For the third challenge students were required to design devices that could eliminate the risk of viral spread through cash transactions. Two of the resulting outputs are shown in the pictures below and demonstrate how […]

DCC 2020 – Poster Presentation (Presented by 8-bit Harry!)

Harry today presented his poster titled “Investigating strategies for mass property replication in 3D printed prototypes” at DCC2020 – virtually, of course, given the world we now live in! The poster aims to introduce the use of variable infill for the purpose of replicating mass properties between as-designed and as-fabricated parts when using rapid prototyping. […]

Voice Loudness Monitor – Instructable

A paper from 2019 found that speaking with a louder voice creates more aerosolised viral particles [Asadi et al. 2019]. This simple Arduino project reminds people to not shout unnecessarily. It could be used in classrooms, meeting rooms or any other setting where people are talking. The equipment list, instructions and code are available here: […]
