Dragoncon 2026

Les Wilhelm

Dragoncon 2026 marks my fifth year presenting at Dragoncon's Robotics and Maker Track. For this year I ran two of my own panels:

  • Gem Magic
  • Resins, Casting, and DIY Composites

I also participated as a panelist in a group panel:

  • Why We Make

Below are the links to the slide decks (and notes) I used during my presentation. If you have questions about any about these presentations, or any other projects you would like to discuss, please let me know. Note The Google slide preview tends to mangle PPTX files. If you want to see the presentation as it was delivered then you will need to download the file and open it locally. Once Google Slides opens select File -> Download -> Microsoft PowerPoint (.pptx)
