Discrete Atomic Luffa Control

• Benjamin Heckendorn
  • An electronics hacking entertainment guru
  • Former host of Element 14’s “ The Ben Heck Show”.
• Chris Kraft
  • A tinkerer currently working as a software engineer in the financial services industry
  • Extensive background in 3d printing and building anything that seems interesting
• Past two years
  • Both where last seen on Episode 75: Does the simulation match reality?
  • Ben has moved on from hosting "The Ben Heck Show"
  • Chris has been experimenting with SLA resin printers
• Hangprinter
  • A very simplified explanation is you take a delta printer but instead of having the three motors that are attached to the side frame you instead locate those motors wherever and have wires/cables/etc that run up to points that you mount
  • Some videos that show how it works
    • Hangprinter Presentation
    • Thomas Sanladerer interviews The Hangprinter
    • Building the Hangprinter: The Basics!
  • The first new/interesting thing Chris has seen in awhile
  • Project is open source so people are free to contribute and find ways to improve the design
  • One thing I feel is potentially a missed opportunity is the focus is on making it cheap
• ODrive
  • Designed to give motor control to hobby grade brushless DC motors instead of stepper motors
  • Hackaday.io project
• New Makerbot printer named "Method"
  • Non-heated bed is a “feature”?
  • Latest design seems to prefer technologies that Stratesys can or already has patented
• Consider the humble Luffa
  • For a long time manufacturing has mostly used subtractive techniques
  • Until recently most manufacturing was about taking raw materials and cutting, bending, etc into the desired pattern
  • Look at that infill
  • Additive manufacturing is really different when you think about the possibilities
  • What if we could use CRISPR to "reprogram" plants to produce other things? Like growing a replacement organs, body parts or something else completely?
