Images

Project photos and reference photos for the parts on the Parts to buy page. One folder per part. Component images come from manufacturer/vendor photography, a freely licensed source, or a file already in this project, and are for builder identification only.

SparkFun and Adafruit images are used here so a builder can recognize the part when it arrives — not redistributed as marketing material. Those vendor photos stay under their owners' terms. Link to the product page for authoritative specs.

Notes

• Originals in BuildYourOwn/RheoBoardOTS/images/ and BuildYourOwn/RheoBoardOTS/cad/concept/ are left in place.
• If a part is substituted, replace the photo here and update the Parts to buy page.
• The sensing setup CAD, using a GL45 bottle and a tube, is in Sensing Setup/. This image folder does not include a photo of those printed parts. The GL45 bottle photo is an example of the bottle, not one of those printed parts.
