Gluing the glass lid back on my Glowforge

Remember back when the handle fell off my glowforge? Or when the glass lid detached from the hinge?  After the laser tube went out, I got a (refurbished) replacement unit, which has been working fine for a year. However, now the glass lid on my new (to me) replacement unit started to detach from the left rear hinge.

Generic WiFi Adapter (SDHC) using the WIFI@SDCF app [Dxingtek/Keytech]

I purchased this (very) generic “WiFi adapter”. (Model AD_wifi_SD) It accepts a Micro SD card, and when powered by a host, generates a wifi network (Default SSID: WiFi@SD, default password: 99999999 [eight nines] ).  I was hopeful that it would expose a webserver that I could access from my linux desktop to download files from the camera’s SD card, but no such luck.

The server resides at, and assigns IP addresses starting at, however it uses a proprietary (UDP packet) protocol that only works with the provided android or iOS app (Called WiFi@SDCF on the Google Play Store com.keytech.wifisd).

Although it may be technically possible to run this app in an emulated android environment on Linux, I didn’t want to put in that much effort. Especially as it appears that the android app (and likely the SD card server) are buggy, and the protocol does not support error detection or correction.  See the class project paper here in the wifi-sdcf repo by David Buchanan for more details.

In short, unless you only want to transfer files to a phone/tablet and are willing to run the provided app (which is of questionable quality) on your device, probably steer clear of this device. [For Sale: One at the cost of shipping….comment if interested.]

How to paint Mouths, Maws, and Teeth

HOWTO Quickly Paint Mouths, Maws, & Teeth

Here is the quick technique I’ve developed for painting mouths and teeth at the tabletop miniature level of detail. First, mouths are very pink. I like this “baby pink” color, but you can pick any shade of pink that looks good to you. Paint the entire inside of the mouth, possibly even getting a small line around the outside depending upon the type of monster or mouth you are painting. I sometimes do this BEFORE laying down the base color of the rest of the face or body, as mouth interiors are usually one of the deepest parts of the model.

Then, water down some bright red paint (I like this “cherry cobbler” color)

It’s February 2022, how is Orange County Florida doing with Covid-19?

The Omicron surge is now on a downward trend in Orange County Florida. However, the number of cases per week is still close to the peak of the delta surge.   Our case positivity rate is “only” 18.2%   (after a peak of 36.2% the week of Jan 7th). That same week there were 27,941 confirmed cases out of a population of 1,457,445, or two people out of every hundred were infectious that week.

The CDC data from Florida in general show that the total deaths from the omicron surge is significantly lower than that of the delta surge.   This is partially due to the fact that more people have been vaccinated (or previously infected with an earlier variant, or already dead), and mostly due to the fact that the omicron variant is generally less deadly than prior variants of the virus.

According to the CDC since the beginning of the pandemic, Orange County has had a total of 2,933 deaths where COVID-19 was involved (11.8% of 24,786 total deaths from all causes in the same time period).   This is a covid-19 death rate of 201 individuals per 100,000 population.

Needless to say, the orange county public schools had a significant number of their students and staff catch COVID-19 as they returned from winter break. However, the total number of cases in the schools has been falling in line with the above county level graph.

Data from the Florida Hospital Association shows that the peak of hospitalizations occurred in mid January. Although almost 20% of ICU beds are occupied by covid-19 positive individuals, there are ICU beds still available and the number of hospitalizations are going down. The total number of hospitalizations for COVID-19 is trending gradually downwards, but the percentage of ICU patients with COVID-19 has slightly increased from this time last month.   Luckily, the majority of patients hospitalized with the Omicron variant do not need to be moved to the ICU.

Adding an orange line showing total hospitalizations in Florida to the number of deaths chart shown above clearly shows that while a significant number of people are being hospitalized, the number is smaller than with the Delta surge, and the proportional number of deaths (when compared to hospitalizations) is also lower.


It’s January 2022, how is Orange County Florida doing with Covid-19?

Over the last three weeks the Omicron variant has proven to be highly contagious. The number of cases and speed of their growth has far surpassed the delta surge. In the last week, almost 1 out of every 50 individuals in Orange County has tested positive for COVID-19.   According to the latest FDOH report, Orange County Florida has had 27,941 new cases in the last week, with a test positivity rate of 36.2%.

This number would be completely terrifying except for the fact that many of the infections are breakthrough infections of vaccinated individuals, who for the most part are protected from serious disease.   However, many vaccinated individuals are also having asymptomatic infections, so the number of infected is certainly higher than the number of positive tests, and the virus is endemic to the population.

The case numbers and test positivity rate tell you that it will be very difficult to avoid exposure to the virus, but the case numbers may not directly correlate to deaths. Currently data from the CDC for the state of Florida indicates that with the omicron surge, so far deaths have not been directly related to cases. This may be due to delays in reporting (or delays in deaths, as the omicron surge really only started a month ago), but it does appear that the omicron variant is less deadly than earlier variants of the virus.

Hospitalization and ICU bed usage numbers are likely to be more directly correlated to future deaths than straight case numbers. According to the Florida Hospital Association, as of Jan 7th, COVID-19 patients made up 16.2% of ICU bed usage.   This is almost double the number (8.7%) a week ago. Adult hospitalizations with covid-19 has gone up from 4,484 on Dec 31st to 7,305 today, again, an almost doubling over the last week.   At the peak of the delta surge, Florida COVID-19 hospitalizations were at 17,121, so it is possible the omicron surge will kill fewer individuals than the delta surge.



It’s December 2021, how is Orange County Florida doing with Covid-19?

The number of detected COVID-19 cases has been flat or going up for the last five weeks. The latest week had a 50% increase (from 1002 cases to 1503 cases), up from a low of 673 cases in the second week of November.
Orange County FL’s new case positivity rate is 4.5% (below the Florida State average of 5.4% in the same time period), but is almost certainly going to go above 5% next week.     This increase can be attributed partially to the new Omicron variant, and partially to the Thanksgiving and Christmas holidays.

It’s November 2021, how is Orange County Florida doing with COVID-19?

We have reached the end of the Delta Surge. The October 29th 2021 weekly DOH report shows that Orange County only had 834 infections in the last week, and the case positivity rate has dropped to 2.9%.   The OC Mayor has dropped the state of emergency, and the OC Public School District has removed the mask mandate in schools. (Faculty, Staff & adult Volunteers are still required to wear masks, as are students, but now a parent note is enough to excuse students from the mask requirement.)

In the last month the OCPS dashboard has reported only 690 new cases.

We have had nine weeks of decreasing case numbers and are now back to a level similar to that of the June/July timeframe before the Delta variant surged.   Orange County currently has 75% of the 12+ population vaccinated, and the Pfizer vaccine has just been approved for use by children aged 5-11 years old.



In the last month, Orange County has only had 140 deaths from COVID-19. Overall, Orange County FL   had 2,185 COVID-19 deaths out of a population of 1,457,445 (149 deaths per 100,000 residents). This is better than the state of Florida average of 285 deaths per 100,000 residents. However, 149 deaths per 100,000 residents is a per-capita death rate higher than the countries of South Korea (5), Australia (6), Iceland (9), Japan (14), Norway (16), Egypt (17), India (33) and the Philippines (36) combined.

Android 12 notifications & Internet Tile are a downgrade

Android version 12 has a lot of under the hood improvements, and I especially appreciate the privacy preserving features (green dot visual notifications when the camera or mic turn on, and finer grained permissions controls).


However, the new notifications system has traded visual appeal for utility. Specifically, the total screen area (width) used to display notifications is significantly narrower than in Android 11. The notifications are displayed with a white space frame around them, and even within that area, each notification is inside a rounded corner “bubble”, so that the actual content is only using 70% of the phone screen width. This is especially noticeable to me on notifications from the Ring app, which show a photo preview of what caused the motion alert to fire.

KODAK Digital Still Camera

Also, they combined the “wifi” and “cellular data” quick action tiles into a single “Internet” one. So instead of two actions to enable or disable wifi (swipe down / click) I now must make four. (swipe down, click internet, click wifi, click ‘Done’).   Also, I don’t appreciate the design of the two line clock on the lock screen, but whatever (no am/pm indicator, really?).

It’s October 2021, how is Orange County doing with COVID-19?

We are nearing the tail end of the Delta surge. The October 1st 2021 DOH report shows that orange county had “only” 2,365 cases in the last week, and our 7 day test positivity rate has dropped down to 5% (for the first time in 3 months…).

The number of cases per day are still as bad as in January/Feb, April/May, so COVID is definitely spreading in the community, but “74% of those 12 and older have received at least one dose of the vaccine” according to Mayor Jerry Demings.   Although breakthrough infections are possible, being vaccinated gives strong protection against infection, and extremely strong protection against getting sick enough to need hospitalization or dying.

Orange county schools have reported 5909 student cases (and 1,114 employee cases) since August 2nd, and are still enforcing a mask mandate through the end of October.


So far, Orange County FL has had 2,045 COVID-19 deaths out of a population of 1,457,445, or (140 deaths per 100,000 residents), which is a per-capita death rate higher than the countries of South Korea (5), Australia (6), Iceland (9), Japan (14), Norway (16), Egypt (17), India (33) and the Philippines (36) combined.


It’s September 2021, how is Orange County doing with COVID-19?

For the week ending August 27th, 2021, Orange County Florida had an average of 1,292 new cases per day. This is worse than the highest previous peak in January.   The exponential growth can be blamed on the Delta Variant and the relaxing of masking and social distancing.

However, the number of new cases each week appears to have plateaued, and the test positivity rate, at 14.9%, while still very high, has gone down from a peak of 20%, so it appears that we may have reached the peak of this delta variant surge.

Historically, Orange County has had a case fatality rate of near 1%, so that would indicate we are due to see about 12-13 deaths per day in the near future, but as death numbers are no longer part of the FDOH weekly reports for counties I have no way of knowing if the case fatality rate has started to drop due to vaccinations of high-risk groups or has increased due to the Delta variant.

We have vaccinated (at least a first dose) 858,281 people (out of a population of 1,457,445), or 59% of the total. If you discount children 12 and under who are not yet eligible for vaccination, Orange County has vaccinated 69% of the eligible population.   We vaccinated 77,829 people in August (Compared to 62,349 people in July, 65,206 in June, 88,482 in May and 151,176 in April.)


Although the FDOH is not reporting county level hospitalization numbers, we can assume that the admissions curves for Orange County are similar to the entire state of Florida. We currently have more people hospitalized with confirmed covid-19 cases than ever before. Elective surgeries are postponed,   hospital morgues are full   and portable morgue units are being deployed.


The FDOH is not reporting death numbers directly for Orange County, but judging from the graphs for the entire state of Florida, deaths are also at an all time high.

The “actual date of death” data lags behind the “reported date of death” data, but as you can see from historical trends, the reported death data is indicating that the actual date of death data will set new records in Florida.

Orange County Public Schools

In the entire 2020-2021 school year (when around half of the students were remote) OCPS reported a total of 5,072 student cases of Covid-19.   (and 2,216 employee cases).

So far, in the first three weeks of the 2021-2022 school year (with the majority of students in-person) the OCPS dashboard has reported 2,599 student cases of Covid-19. (And 624 employee cases.)

Have we reached the peak?
In other countries surges driven by the Delta Variant have peaked hard and then receded quickly (after natural immunity is reached in the un-vaccinated population via infections) so we we may see a sharp decline in cases, hospitalizations, and deaths in September.
