Arizona Covid-19 running tally

This is my running tally of the Covid-19/china flu/kung flu infections in Arizona. I will update it as often as I can with the number of confirmed cases, and deaths. I will continue to do this till the pandemic is over, I get sick and/or die, or get bored.My sources: azdhs.gov and Wikipedia.


Number of new cases with 7 day moving average.
2.907930% of total population infected (Arizona)
.38% of the worlds population (known infections) 

Arizona Terminal Percentage 2.56%(number is fluctuating).
Global Terminal Percentage 3.14% (this numbers is falling)
increase in cases from 10 days ago (Arizona) 2.65% 
1 day increase .84%
Average number of new infections per day since 3-13-2020 1120 (number is falling)
at present rate of infection it will take 29.9 years to infect all of AZ.
average number of deaths per day since 3-22-2020 30 (this number is steady).
Average number of deaths per day in all of Arizona for all reasons(based on 2018 numbers) 102
number of suspected asymptomatic or unreported infections in Arizona 657,681.This number is based on results in AZ of the infection percentage (11.9%) from tested people extrapolated to the total AZ population minus the known number of infections.

updated 9-13-2020
8-9-2020 we are over the hump of the second First wave.

7-26-2020 Added Monthly closeup graphs below.

7-22-2020 we hit 2% of AZ population infected.

7-19-2020 we appear to be over a hump at this time, however when schools reopen in August it will get worse.

7-18-2020 actual numbers are 141265 and 2742.

7-8-2020 new prediction there will be 140112 infections, and 2143 deaths on 7-18-2020.

6-28-2020 1% of the AZ population is now infected.

5-31-2020 Testing Blitz in AZ is reason for more infections being found in the last week.

5-13-2020 my prediction was exceeded on 5-13-2020 with 12176 cases so my calculations are pretty close.

5-4-2020 Prediction 12003 cases by 5-14-2020.

3-30-2020
Although this data is pulled from websites that are up to date, it may reflect information that is 1 to 3 weeks behind the actual number of infections.



Stop the spread Stay home!

Remember we are all dying because some fucking moron in another country has to eat an exotic animal, and they haven't stopped because of the pandemic.

For the first time in recorded history, all you have to do to help save the world is stay home and do nothing. You'd think we'd be able to not screw that up.

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.
