My reviews & how-tos for adding machines and other antique calculating devices.
Curated by: Chris Staecker (120 videos)
The Postagemiser, from the 1990s (and before), plus the "Postal Scale small and portable analog weight detection device". Both are pendulum scales! This is episode 53 of my video series about calculating devices. End song inspired by "Hotter than a molotov" by The Coup. #dengar Chris Staecker webarea: http://cstaecker.fairfield.edu/~cstaecker Irene photo from https://commons.wikimedia.org/wiki/File:Irene_Bae_at_DMC_Music_Festival_in_September_2015_02.jpg CC-BY 4.0.
