Welcomed Makers.

Awesome group of makers from  Educator, Black Smith, Artist, Programmer, 3D Modeler, Inventor 

Topics of conversation:

  • 3D Printer:

    These are the two slicers/controllers we’ve been using recently:
        Cura – Easy to use, good prints, good included slicer  https://ultimaker.com/en/products/cura-software
        Repetier – Lots of control, supports multiple slicers, a bit more complicated  https://www.repetier.com/
    If you are looking for pro-level software (runs $150) — Simplify3D is widely used. I’ve yet to try it out (no trial — you have to pay for it, then have 2 weeks to return). https://www.simplify3d.com/software/As Dan mentioned, we’re pretty much switched over to using Autodesk Fusion 360 for modeling. Harder to use, but very powerful. Requires a software install, but is free for home/student use. Very good if you are starting with engineering specs and modeling off of them — for example, we can get the specs off McMaster-Carr for various parts, and use those measurements for models
  • Astronomy Education:

Projects

  • Central Texas Maker collaborative project will be  “Rube Goldberg” type machine which will be displayed at the CCPL for the community to see and learn what cool things are happening at the library.Initially the group decided to have multiple parts that come together to make this project.  This allows each member to participate.
  • To participate you’ll need to do the following:
  • UPDATE  —  NEW Guideline:
    At tonight’s meeting,  the group decide the following guideline.  Breaking the Rube Goldberg project into a grid.   Choose which grid slot to make your own mini Rube Goldberg.  Make your design to have a ground level entry and ground level exit.  Ideally the 16 slots will come together to make the team Rube Goldberg project.  Remember to email Evelyn which slot you picked to work on.

    • Build your own “mini Rube Goldberg project”

        (either battery or solar power)
      • Ball size or marble 1/2 inch or less
      • The Entrance and Exit are at the half way point of the 1 foot as mark with the arrows above.
      • Choose one of the 16 slots available
      • Draw your mini Rube Goldberg project idea
      • List the materials needed to build your mini Rube Goldberg project.
      • Building your project using found objects or materials laying around and about your home.

      Criteria Limitations        

      • No Plug-ins
      • If crashing object it should be able to RESET
      • Height should not exceed 2 feet

        Kevin says:
        Some random ideas:
               I can provide a 4’x4′ plywood base.
               Can we standardize on 1/2″ ball bearings and 3/4″ clear plastic tubing for many applications?
               Any support structures can be assembled from 3D printed or laser-cut parts.
               All sensors, lights, switches and sound effects can be controlled through arduino boards.
               I want to make a small steel helmet that gets hit by a ball bearing to trigger a switch.

Saturday Seekers

  • This program has brought together a number of makers. We’ve worked on individual projects, brainstormed new ideas, and helped each other learn new skills.  
  • ANNOUNCEMENT — In the month of August Saturday Seeker will be by appointment.  Please make appointment by email two (2) days prior to Saturday Seeker.

Show & Tell

Monoprice 3D printer with heated bed discussion on quality and affordability.
Member Ron Nelson brought his 3D printer.  He talked about benefits and challenges of this particular model.
He also showed different 3D prints made by this model.  (As shown above, blue kitty)

Raspberry Pi 2 laptop with Pi-Top assembly kit

Member Dr. Dan Kotts brought his latest project the RP2 with assemble yourself laptop kit.  He shared his experience assembling this very affordable portable computer.

He also brought with him the Astronomy Education models mentioned above.
