Soldering - the good and the bad

I saw this over at the Music Electronics Forum. Everyone needs to read it.

Funnily enough my next fuzz project is going to be sent into orbit by the European Space Agency.

Great post, as usual.  Thanks!!

Tee-hee!

But shouldn't it be made so it COULD BE??

Good read. Thanks.

Worse than anything encountered in space:

Did NASA have a similar spec for fitting O-rings?

[slacker]

I thought I had some decent soldering skillz 'til I read that

I like the idea for reinforcing glass components though.

Good post. Good guide
NASA is EXTREMELY picky about solder joints. I should know. I worked at JPL back in the late 80's
And believe it or not, by that page, it seems they are slacking off.
There are a few "Acceptable" things there that were BIG no-nos back then.

But its a good guide none the less

Did it work? ^^^

Low very low 

Still laughed though, I know I shouldnt but Meh!

Really classy.   


Hey everyone needs to shrink wrap their Ge's & Si's now, mKay?

It wasn't meant to come across as a humourous comment ... maybe I should've said, "Did those ba$turds at NASA have a similar spec for fitting O-rings, probably not?"

Sorry if I upset anyone that thought I was making a joke of it.

Should have a whole scanned book on military electronics standards, the non-stripped-down version of the above link.

It's a nice challenge trying to follow these too.

[EDIT] may come as a bit of an OT but here's one method to test mil-spec pedals: http://youtube.com/watch?v=hKZLNKqvFAI

Very good! +1 to previously thinking my soldering skills were OK!

NASA didn't have anything to do with Challenger's breakup, it was upper management at Morton Thiokol that ignored the engineer's concerns about the launch conditions. There was a spec, and it would indicate that the launch conditions were outside of the safe operating temperatures of the seal.

I don't mean to be a d-bag, I just had to join the conversation being a space junky and all.

I've just been schooled.  I thought I knew how to solder!

I was trained in the late 60s with an Australian Government organisation, and I'm a little surprised at some of the "Acceptable" things as well.

Maybe slightly OT, but I'm seeing many cases where anal neatness is becoming more important than functionality.  Yesterday I worked on a PA system rack that has a digital microphone, using Cat5, unshielded, cable.  The mic is occasionally going into busy mode, requiring the cable to be unplugged to reset the mode.  The rack is very neatly cabled, so neatly that the Cat5 cable is tightly tied to the 100V line speaker cables for at least 2 metres.  I'm betting that induced voltages from the speaker cables into the Cat5 are exceeding the capability of the digital interface to combat noise.

Well, I thought it was a joke, and a pretty damn good one, and I even laughed. I guess that makes me the ba$turd.


Anyways, whole else found themselves guilty of at least 10 or more violations?
