Study Notes

Makers and the Democratisation of Technology

  • The presentation explores the maker movement, examining its context, enablers, examples, disruptive technologies, and concluding remarks.
  • The maker movement encompasses a DIY approach, encompassing traditional crafts to cutting-edge technology.
  • Designs and ideas related to the movement are shared online.
  • Domestic-level access to the web, prevalent from the mid to late 1990s in the UK, enabled information exchange.
  • Web 2.0 technologies empowered relational connections through online social networks.
  • Sharing of media like music, videos, and daily thoughts rose dramatically.
  • The rise of mass-produced, inexpensive goods, especially from countries like China and India, influenced the market.
  • Karl Marx and Frederick Engels' concept of the proletariat is highlighted in the context.
  • Proletariat is defined as the class of wage labourers lacking their own means of production, compelled to sell their labour to survive.

Context of the Maker Movement

  • The maker movement's context includes a DIY approach incorporating traditional crafts to cutting-edge technology.
  • Ideas are shared online.
  • UK web technologies, from the mid-to-late 1990s, enabled information exchange and connection.
  • Web 2.0 technologies led to online social networks and relational connections.
  • Sharing of music, videos, and daily thoughts increased significantly.
  • Production of inexpensive mass-manufactured goods from countries like China and India expanded the market.

Examples of Enablers

  • Arduino: Open-source hardware microcontroller.
  • Web-based communities of practice (e.g., DIY Drones & UKHAS).
  • Make Magazine: A traditional magazine from O'Reilly Media.
  • Technology-based road to market (e.g., Etsy).

Disruptive Technologies

  • Crowdsourcing/crowdfunding: Peer-to-peer finance, micro-investment.
  • Kickstarter: Example of a crowdfunding platform with over $6,838,584,763* pledged to projects (as of September 2022).
  • Personal fabrication: 3D printers & scanners (e.g., RepRap - open-source, Shapeways - commercial, Thingiverse - shared content).

Fabrication

  • Two main approaches to 3D printing: Fused Filament Fabrication (FFF) or Fused Deposition Modelling (FDM) and Resin Printing (Stereolithography).
  • There are also alternative methods like Polymer Powder Sintering.

Advantages and Disadvantages of 3D Printing

  • Advantages: Customisation, rapid prototyping, complex shapes and structures, in-situ/tool-less production, sustainability/environmental friendliness, efficiency, new business models
  • Disadvantages: Limited materials, safety concerns (especially with plastics and food),intellectual property issues, 3D design software complexity, printer costs, speed, unchecked production issues,energy requirements, warehousing/storage needs, ethical issues and employment impacts.

Criticisms of the Maker Movement

  • The maker movement has faced criticism regarding gender and race inclusivity, as well as democratisation.
  • Examples include Make founder Dale Dougherty's public criticism of Naomi Wu (2017) and his subsequent apology.

Conclusion

  • The past ten years have focused on discovering new ways to create, invent, and collaborate online.
  • The next ten years will focus on applying these lessons to the real world.
