While commonly associated in pop culture with the likes of the Looney Tunes, Blasting Machines are practical tools which have been used in mining, construction, and many other industries for over a century and a half. In this video, we look at three different models of blasting machines:
-Dominion Electrical Works plunger machine (c.1930s)
-Exploders Dynamo Mk.VII (1940s-50s)
-Exploder Dynamo-Condenser Mk.II/III (1950s/60s)

![Bendix AN5841 API Computer: Flight of the Navigator
Introduced by the Pioneer division of the Bendix Corporation in 1944, the AN5841 and the associated 12580-3-B Air Position Indicator System were used aboard late and post-war long-range military aircraft including the B-29 Superfortress. The system integrates air mileage data from a pressure pump system with heading data from a compass to continuously track the aircrafts latitude and longitude from its point of departure. The navigator could then add the wind vector to determine the true ground position.
