My electrical construction experience is only since 1996, but you work around other contractors. The experience is enhanced.

He never mentioned headlights at all.   I've seen more and more LED headlights out on the road with 18-wheelers. Its like several LED bulbs are packaged into each separate headlight.

Much better than WD40. I have never used Kroil. Mostly cuz I never see it sold anywhere in auto parts stores. But I heard it's good......   What is "Ed's Red"?

tubeguy@myshop.com: Feb 01 12:56PM -0600 I have never heard the term Gigaohms used with resistors. Is this a valid term? With computer hard drives, if a drive is 1000 megabytes, it's called one gigabyte.   Using some resistor color code software I have, it does not use that term. For example, brown black gray says 1000M. or red red white is listed as 22,000M   In real life I have never used any resistor with that high of a capacity, I dont even know if they are made, but would 1G or 22G be valid for the examples above?

They look like reed relays at first sight, enclosed in presumably evacuated glass envelopes.

(In fact they sell 500 Gohm resistors in surface mount.)   One thing to remember is that they're very very slow--a 500G resistor makes a 1-second time constant with 2 pF!   Cheers   Phil Hobbs   -- Dr Philip C D Hobbs Principal Consultant ElectroOptical Innovations LLC / Hobbs ElectroOptics Optics, Electro-optics, Photonics, Analog Electronics Briarcliff Manor NY 10510   http://electrooptical.net http://hobbs-eo.com

tubeguy@myshop.com: Feb 01 12:56PM -0600 I noticed that Walmart sells a aerosol can of what is called "Contact Cleaner". (For electrical switches and stuff like that). I have never used it.   In the old days I used Radio Shack's contact cleaner. These days I use Deoxit, and I think Deoxit is a great product. But Deoxit is quite expensive, and has to be mail ordered. For expensive electronics, potentiometers, and similar, I'll use Deoxit, but for common slide switches, push on connectors, and other non-critical items, I'd like something cheaper to use, and easier to buy.   I have to wait till I get ot Walmart again, but if I recall, I think the brand is GC Electronics, and it sells for about $5 to $6 a can. It's sold in the automotive department (along with other chemicals such as carb cleaner).   Have any of you used it? Is it any good?

"Ron D." <ron.dozier@gmail.com>: Feb 01 11:35AM -0800 Cool. Surgeries are done on internal battery backed up Dallas RAMS too to access the pins for the battery, The new battery is placed on top.   If you have the map where to remove the Epoxy, You stand a good chance of repair.   Desoldering the chip (heating it) might destroy it's contents.   FYI and ASIDE: Had an ultrasonic bonder at work to play with, but it did not work well.
