"The LEDs can glow with only microamps of current. One message in the linked forum post indicated that just touching some piece of metal to the input of these LED lights can make them glow from close-by AC voltages. The only question I have now is why it's intermittent." You say there is v...

What kind of soldering iron? How many watts ? Is the tip of the iron clean ? A dirty soldering iron tip will not transfer the heat needed to melt the solder. An adjustable one, with the temp turned way down won't work either. When you try it again, try adding a little new solder to it to help make i...

"Side kick: Ever notice the 'soldering experts' on YouTube, they melt and smear. Probably became certified through a training session at Sam's Drywall Finishing School!" I've noticed that also, and when my students see it they want to know why the youtuber can do it that way, and not them....

Where I used to work we built large air conditioners. Our specs for the longest read "Length 42' +- 2mm". The bad part was our inspectors were only equipped with 6" dial calipers and a calibrated 16' tape measure. I asked an inspector once how he knew the length was ok, he said if all...

We get phone, tv, internet from our phone co-op. They won't connect you for just tv or internet, you must get a landline. We had fiber installed when it became available last year, runs pretty good.. My wife pays the bills so I don't remember exactly what it all costs, seems like $140 or so.
