Panasonic RE-7700 Automatic Tuning Stereo

picked this up from goodwill today for very little as it did not power on.
The reason it did not power on was that a small tab of copper or copper plated steel that actuated the power switch had been knocked off the switch.
in order to get the top of this unit off remove the screws circled in red, to get the bottom plate off remove the red and the green circled screws.
You will also need to remove this screw from the top side. I ended up drilling a hole through the plastic in order to get to it. You will definitely have to do it to put the screw back in.
The schematic is inside the stereo under the top cover. If yours is missing here is a very high resolution scan. Dial string instructions included.
Or you can download a pdf that contains it, and better printable copies.

Philips 800Lumens 8.5w 2700k LED light bulb failure mode

We purchased several Philips 800Lumens 8.5w 2700k LED light bulbs in January of 2017 from Ace Hardware the bulbs have a UL number of 3PM5. About a month ago one of them stopped working and I took it apart. I was hoping to repair it, but found that it was not possible due to how it was put together and because the small transformer on the circuit board had broken apart and fallen off the board.

Today another one started going out. it started blinking on and off. I replaced it and opened it up, I found that same issue the small transformer had fallen off the circuit board, and there was the smell of burned components, and an electrolytic capacitor on the circuit board had overheated and popped.

The bulbs were mounted in a ceiling fan light fixture that is open and pointing down at about a 45° angle. The bulbs are supposed to last 22 years at the ridiculous usage of 3 hours per day. The warranty was 3 years.

Everyone Was Kung Flu Frightened!

Today the wife and Mother-in-law decided we should go out for a drive. We headed to the north scottsdale/Phoenix area. On the way back we headed down Cave Creek rd. and since we were in need of some items we had forgotten to get on previous trips to the grocery store we stopped at a Fry's on north Cave Creek rd.

Here what it was like:
it goes without saying that there was no hand sanitizer or medical alcohol.
No bottled water
 No Bread
 No Canned Foods
No Pasta
 No Rice and Beans
 Not much in the way of soap
 and of course the one item that makes you invulnerable to viruses...
NO Toilet Paper!
Now the rest of the aisles were mostly normal. I figured that rich people would just order their stuff from Zanzibar and not worry about it.

LG's Scare mongering


Watch this video of Louis Rossman's evaluation of the scare mongering campaign by LG regarding 18650 batteries
#LithiumionBatteryCells, #18650, #StaySafeBattery

Way to blame the consumer LG!

How is not selling legit good batteries going to prevent this LG?

It is apparent from the video that LG thinks the average consumer is a complete moron.

It's too late there are tons of products on the market with consumer replaceable 18650 batteries. The cat is out of the bag. So instead of throwing gasoline on the fire how about finding ways to make LION batteries safer?

Rossman is right again.
