The modular neck weight project page is now live. It covers the collar build, the add-on weight modules, and where the supporting techniques live in the lab guide.
If you need the build steps, you can read the full guide here: Neck Weight Project.
We added a short guide to the measuring vacuum section that covers the trapped balloon gauge. The write-up walks through how to size the container, prep the airflow holes, and use the balloon expansion as a quick visual check that a bag has pulled down to around 80% of atmospheric pressure.
If you need a reference while setting up a bag, read the new page here: Trapped Balloon Vacuum Gauge.
The bike-spoke nose clip project page is now published in the lab guide. It documents the parts list, bending sequence, and finishing steps used in the current build.
