45 Housings and Cases

An Adafruit permaproto board is 2 inches across, and will just slide into a sleeve of white ASTM F2158 2″ (50mm) O.D. PVC Vacuum Tubing, available at Home Depot, etc. The tubing needs to be deformed a little to get it in, then holds it tightly without additional fasteners. Adding some aquarium hose and a funnel can yield a fairly weather proof housing for prototype instruments in a greenhouse.

For something more professional looking and more weather proof, a small Pelican case provides easy access during the prototyping phase and into production.
