Things that give me migraines

I have found these 2 things will give me a migraine either within a day or 2 of taking.

Niacin within a couple of hours of taking 125mg of it. 2 days in a row.

Flaxseed oil. I started taking this since fish oil makes me sick. I was taking it for 2 days and got a migraine, then on the 3rd day got another. 4th day no migraine, fifth day another migraine. stopped taking the flaxseed oil and no more migraine. I had not had a migraine prior to this for almost 3 years.

Panelization in EasyEDA

The instructions for panelizing a board in EasyEDA are absolutely terrible and confusing, they lack any useful information. 

In easyeda select tools then panelization.

Select the number of rows and columns BUT keep in mind that their machine can only accept a minimum size board of 7x7 Centimeters. So you will need to select a minimum number of rows and columns that meets or exceeds this number. as an example I have a board they is 18.75x8.5 millimeters. in order to meet the minimum requirements of panel size my board needs to be 4 columns by 10 rows high. The minimum column and row spacing is 1.6mm. I do not need boarders.

Originally based on the instructions (I found) I thought I had to account for the board size when selecting the spacing and put in 18.750 for columns and 8.5 for rows which got me very strange results.

There is still some confusion on whether you need to copy and fix the circuit to each board. it appears that you do not (JLCPCB will supposedly do this for you), but there is conflicting information about this on line.

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.

Stop cats from chewing on an oxygen line

Purchase a small bottle of orange scented anti bacterial dish soap, and a bottle of Angostura orange bitters. if the bottle of soap is completely full use or dump out 1 or 2 tablespoons of the soap. Add 1 to 2 tablespoons of Angostura orange bitters to the soap bottle and shake. Using a paper towel or small rag pour a generous amount of the mixture on to the rag and run the oxygen line through it adding more soap if needed. The oxygen line should be slippery when you are done. Coat every bit of Oxygen line the cats can get to unobserved.

Repeat every couple of days. Add more bitters for stubborn cats.

Cats do not like the taste of orange, the anti bacterial agents also have a bitter taste to them, and the bitters contain bitter orange. The combination should keep them from chewing on the Oxygen line. I do not know if it will work for other animals.
