Blowing Things Up
wbswenberg   8/23/2012 12:21:11 PM
I worked on the battery charger for the Peacekeeper missle in Minuteman silo.  There are two battery systems; megga lead acid traction batteries and lithium primaries.  The battery charger had .1 farad capictor which required discharge in 30 sec to less that 30 V and the circuit had to be redundant.  If the drawer is pulled out for maintenance the caps are discharged so as to not shock and possibly kill someone.  In the lab we are doing reseach to make sure we have met all the specs.  We have a device to defeat the micro switch that completes the circuit when the drawer is pulled out.  We installed the ciruit and defeat test aid.  I left for the weekend knowing there would be testing.  So the last words to the other engineer and tech was Don't forget the interlock defeat.  I got in Monday morning and did I ever hear about it.  They forgot.  The four wire wound resisters blew like dynamite.  There was white powder over everything from the ceramic core.  And the wire sprange out of each of the Al houseings of the resisters.  No one forgot after that.

What trips my trigger

I agree William L Weaver, it was the manned space program, specifically Neil Armstrong and Buzz Aldrin, walking on the moon that made me want to be an engineer. I was 5 in July 1969, and I caught the Apollo bug bad. I knew that we could send men to the moon, then we could do anything.

I have the opportunity to manufacture product that is used by emergency crews when they need to help people.  It is a great feeling to see a firefighter using one of your chainsaws to help people in need.

Nice video, Sylvie. I particularly like the idea of blowing things up. But all of the interviews are good.

The Simple Life

I like finding simple solutions to complex problems, whether it be a circuit with a handful of components or a fragment of code that only requires a few lines.  As Engineers we tend to over-design so I really love it when a simple solution can be found.

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?

Get your Allman Brothers albums ready. The iconic Volkswagen Microbus may be poised for a comeback, and this time it could be electric.
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
