OVERVIEW As part of an outreach effort for NPRB 1218, I spent three days at Blatchely Middle School in Sitka, AK, (April 22-24) presenting the concepts of array beam forming to five periods of Stacy Golden’s science class. My motivation was to use NPRB 1218 as an opportunity to explain to students some fundamental physics and engineering concepts that extend way … Read More
How to charge a dead battery for the decoy device
When not used for long periods, the batteries should be disconnected inside the decoy to prevent full discharging, because if the battery pack voltage falls below 1.5 V, the charger IC board will not permit charging. However, here are some steps to “resuscitate” a dead battery pack. Warning: you will need a 12 V power supply with alligator clips … Read More
