Artifactor Scanning System

Session date: Saturday, June 14, 2025 01:00 PM
Duration: 4 hours 45 minutes
Timezone: America/Los_Angeles

A simple, convenient, fast, and durable system for unidirectionally scanning three-dimensional objects has many applications in archaeological fieldwork and cataloging collections. Please join us for a presentation on and demonstration of the Artifactor Scan System, a fossil and artifact scanning platform created by Tara Johnson and manufactured at Maker Nexus in Sunnyvale, CA. Using the Widar software (subscription required), scans take approximately 3-5 minutes to collect and 15-20 minutes to process. Please feel free to bring your iPhone and a non-fragile artifact, roughly 1 cubic foot in size, to try scanning for yourself. The Artifactor Scan System is still a prototype, with new types of clamping supports under active development, so feedback on possible new use cases would be greatly appreciated.

Tara Johnson is a junior at Irvington High School in Fremont, CA. She has eight years of experience applying computer modeling, programming, and rapid prototyping technologies in the digital humanities. She is the creator of the Artifactor scanning system, which was prototyped at Maker Nexus and is being tested in collaboration with the Children’s Natural History of Fremont. She is also a contributor to Pyhiero, a Python-based computational linguistics processor that translates Manual de Codage (MdC) notation to Unicode Egyptian hieroglyphs.

The seminar will start at 2:00 pm PT and formally conclude at 4:00 pm.
Friends are welcome and also invited to join our organization. There is no participation fee.

1:00 – 4:00 p.m. PT
at
Roger and Lydia Peake’s home
Kevin Smith, PhD archaeologist and SAS scholarship winner will lead Society members in the use of flint knapping techniques. Kevin has been making stone tools since he was 17 years old and also replicates artifacts for local museum displays and for experimental archaeology which is a major research emphasis.

The event is scheduled for 1:00 PM PT to 4:00 PM. PT on Saturday, October 21. This will be an opportunity to enjoy hands on time with obsidian and chert. Since we’ll be working with sharp objects, safety glasses, tight fitting work gloves so that they can feel the materials but protect their hands and closed-toe shoes (no sandals), and a heavy towel to protect legs arms and legs are a must. Long pants and long sleeves are also recommended for protection. If you have obsidian, chert and any flint knapping tools, please bring them. Kevin will provide antler, hammer stones tarps and some obsidian and chert.

Flintknapping Workshop

Saturday, May 2, 2015

2:00 to 5:00 p.m.

 

Dr. Susan Gleason

Archeologist, Phoenix Obsidian Designs

Experienced Lithic creator and instructor, Susan Gleason will teach Society members flint knapping techniques with obsidian.  This will be an opportunity to enjoy hands on time with obsidian.

Dr. Susan Gleason earned her doctorate in Anthropology from the University of California, Riverside in 2001. Her dissertation, “In search of the Intangible: Geophyte Use and Management Along the Upper Klamath River Canyon” reflects her research in topics on prehistoric technologies including flintknapping. Flintknapping is a process of making stone tools. Her research has also focused on ethnobotany or how people interact with plants. As an artist, she has developed unique arrowhead jewelry and created a line of educational materials.

Her business, Phoenix Obsidian Designs, produces tools to assist archaeologists and other educators to teach about prehistory. In addition to educational tools, the company produces museum quality replicas of archaeological artifacts for a variety of uses. Phoenix Obsidian Designs provides a line of supplies to support experiments in prehistoric technologies. Producing educational materials is the focus of her business.

Dr. Gleason has had a wide variety of field and laboratory experiences and as a consultant, contractor, and scientific illustrator. She has given numerous lectures and demonstrations with an emphasis on flintknapping and lithics. She is or has been a curator and collections manager. She has numerous publications and reports to her credit; and has presented a variety of papers on topics in archaeology and ethnobotany. And, she has been professionally recognized with a variety of honors and awards.

Reservations for this event are required so that Susan knows how many tools and how much material to bring. Please contact Roger and Lydia Peake at rapeake@att.net to reserve your flintknapping spot by Monday, April 27th.

Fees:  $10.00 cost of the workshop is the teaching cost and includes whatever take-home “points” that are made by participants. Each participant pays this cost.  A $30.00 cost includes the tools she provides for each participant’s use (e.g. leg protection etc.) AND the teaching cost. So, she is selling the tools used by each participant for $20.00. The “tools cost” is voluntary and would be paid by each participant who chooses to keep the tools.

Since we will be working with sharp objects, leather gloves, eye protection, and a heavy towel to protect legs and arms are a must.  Long pants and long sleeves are also necessary protection.

Bring your favorite dish for a pot luck dinner after the workshop.  Invite your friends to participate and join the society.  This is a member only event.  Questions?  Please contact Roger and Lydia Peake at rapeake@att.net
