Upcoming update to Science Sunday at the Dallas Makerspace will try to add a bit more structure to the meeting and to give potential participants more clarity as to the types of activities to expect on any given Sunday. Within the next month or two, Science Sundays will have the following general format instead of our current completely informal meetup. While not every type of activity will occur each week, specifics about what to expect will be posted weekly on this page prior to the meeting:
1.Fun Public Activity / Demonstration:
Whenever possible, we would like to have a fun activity/demonstration that people can stop by and try regardless of their scientific background.
2.Rotating Group Research Projects
We plan to update our group project selection schedule different projects each week such that people with different backgrounds can get involved. Our focus will be developing learning, tools, and resources, that can be useful to increasing capabilities here in the Science area or at the space as a whole. We anticipate that various engineering, design, and creative skills whether using glass, metal, or plastic will be required while we prototype new stuff. So we hope that you would consider joining us on the weeks where the projects catch your interest. When working on projects relevant to other committees, we hope that you can contribute your domain expertise and advise us. Results and guides will be published here as a resource for the community.
3.Volunteer and Contribution Activities
Inaugural Science Sunday: Slime and Smoothing (12/1)
1. Fun Activity: Make Slime and Oobleck
Our fun activity of the week will be a simple classic. We will make both slime and oobleck and you can take home a container of slime with you as well. Feel free to stop by as long as supplies last even if you aren't planning on participating in our group research project.

2. Group Research Project: 3D Vapor Smoothing Chamber Planning Session
We have selected the design of a new, improved 3D Vapor smoothing chamber as our initial project. This first meeting will be mostly a design and planning meeting covering the following items. (1) The current state of the of the chemical mechanical polishing process will be demonstrated so that improvements can be suggested and tools designed. (2) We will then discuss the proposed design of the 3D vapor smoothing chamber and determine the overall scope and goals of the project (potentially publishable results) as well as putting together a plan to build the first test chamber. (3) We will also work on designing a printed test pattern to use as a sample which will be cross-sectioned (possibly via lapidary type polishing methods after setting in epoxy) and examined under the microscope. (4) We may potentially improve process control using acetone concentration sensors that we develop. This would also potentially allow us to use CFD to model the vapor flow patterns and inform modifications to the design.
See: Vapor Smoothing Chamber for ABS 3D Prints for more details.
Potential Relevant Fields and Skills: 3D printing, Mechanical Design/Engineering, Lapidary/Polishing, Laser (sensor fabrication), Electronics, Automation, Metal Working, Glass Working.
Finally, various housekeeping/upgrade/build activities will be periodically scheduled similar to how other committees have work days.
