On this page I would like to introduce you to another project of mine that has nothing to do with the topic of “brewing beer”:
SMALEBO (SMArt LEtter BOx)
SMALEBO is a 3D-printed mailbox sensor that uses an optical signal or a smart phone to inform you whether there is new mail in the mailbox and whether it has been emptied after it has been dropped. And by that a perfect addition to your “Smart Home”.
If you want the associated CAD files in FreeCAD format (FCStd) or if you have further questions, please use the contact form to contact me.
