Indeed shehan, that's sound advice especially in matters of safety.

Shehan, to avoid causing static damage to components it's best to wear a properly grounded (through about 1 Meg) wrist strap and/or a static-dissipative heel strap and use a static dissipative work mat, rather than wearing the rubber footwear you suggested.  Rubber footwear insulates and would allow a static charge to build up.  It's important to dissipate any static charge.

The reason for the 1 Meg or so series resistance:  suppose you had a low-impedance ground strap on one wrist, then got hold of voltage (including breaking a light bulb above your work bench or touching the socket when changing it) with the other hand.  Current path straight through your chest & heart.

Isn't that amazing, Wirkmanv. It's hard to believe. Yet, there may come a day when I forget to check the power source before I panic when a product doesn't work.

An old friend of mine use to have his own TV shop.  When he would get a call from someone that the TV did not work and could he come fix it he would always ask them to check behind the TV to see if it was plugged in.  He said this solved may problems without his ever having to leave his shop.

Reminds me of a problem I encountered while attend a Navy C school on an airborne HF receiver/transmitter.  A portion of the system was not working properly because the instructor had created a problem for me to troubleshoot so to start with I took out the fuse and looked at it.  It was a clear glass variety with the metal end caps.  Fuse looked fine so I started looking as some other things.  Everything kept pointing back to the fuse.  So I took it out and checked it again with a meter.  Voila.  It was blown but in one of the two end caps so it looked fine.  Taught me a lesson that I will never forget.  Once I replaced the fuse I found another problem.  The one the instructor had put in the system.  Took both solutions to the instructor.  He kept the fuse and said he would use it on in future troubleshooting exercises.

That's good advice, Shehan. I would imagine most people don't bother.

German engineering

With over 40 years experience in electronics (fault finding, development, design) i would suggest that remark about German engineering is so wide of the mark, it's actually laughable. As far as brands are concerned, my car is a 1972 VW Beetle (only the germans can make a car that still drives so nicely after 41 years), my motorbike is a 1978 Motor-Radwerk Zchopau 250TS-5 cafe racer, i'd like to see a production HD last as long... my electric drill is a Bosch.. etc etc. FWIW, American stuff is usually good also...

As far as not buying German brands, many of my family perished in the camps. so what?... the war is over... and it has nothing to do with the quality of German engineering.

I think he means to say that only a German company can sell a component at quality price, with quality expectations, and then have it fail. When a cheap far-east component fails, it's still living up to expectations.

My mother told me never to buy a German car - her experience with Messerschmidt,  Heinkel, Focke-Wulf, Junkers, and BMW quality technology was too up close and personal in 1939-1945.

@a.saji – It's always important to take precautions before something happens. The slightest mistake could easily set up a fire damaging your entire property.

RIDICULOUS comment!

Rob! 

You should be ashamed of yourself for allowing this blog to make it to the airwaves.  Criticizing German technology in the low-class, demeaing, insulting manner with which this entry was made is totally classless, and doesn't belong in a technical magazime forum.  While freedom of speech IS a sacred right in the U.S., this commentary was not only offensive, but totally without merit & not GERMAiNe to the story.

p.s.  I am of GERMAN descent, and VERY proud of it, although my pride for the U.S. is far and away MORE important to me and has been for my entire life!
