I made a video about a rock.

This is a rock called Biotite granite. It is a medium-grained, all crystalline rock with pink feldspar, gray quartz, and specks of black biotite - a type of mica found in igneous and metamorphic rocks.

Biotite mica is a composition of annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others.

Biotite is a rock-forming mineral found in a wide range of crystalline igneous rocks such as granite, diorite, gabbro, peridotite, and pegmatite.

Biotite has limited commercial use but may be as a filler in paints and drilling mud or as a non-stick coating on shingles.

Grieving Friends pinhole photographs

These photographs are of the Armed Forces Tribute Garden Monument in Westminster, Colorado. The sculpture is called "Grieving Friends" and is by Bill Hueg, David Parvin and Eliot Summons. I made these photographs with the Harman Titan 4x5 pinhole camera with the 110mm f/250 cone. My light meter read 1/30 sec @ f/16 which computed to a 14 sec exposure on ILFORD FP4 Plus ISO 125. I developed these in ILFORD DD-X for 11 minutes.

Photographs made with a pinhole camera can take on an almost surreal appearance with a soft focus. One of the qualities of a pinhole photograph is that the foreground, middle ground, and background all have the same focus.

One ring to rule them all

I still need more practice with the Toyo 4x5 view camera, but I'm pleased with the result.
Toyo 45A 4x5 view camera, 1/8 sec @ f16. ILFORD HP5-400 black & white film. Developed at home in ILFORT DD-X.


This photograph was made using a Harman Titan pinhole camera with a 110mm f250 cone. The exposure was about 8 seconds. Unfortunatly I scratched the film, got fingerprints on it, and it had a lot of dust on it. I was able to cleanup a lot of it in Adobe Lightroom. I'm happy with the result.

Pinhole photography

This is a still life of some dark room equipment. I took this photograph with a Harman Titan 4x5 Pinhole camera and the 110mm cone. The cone has an f250 aperture. Pinhole photography produces very different results than an ordinary camera. Photographs made with a pinhole camera can take on an almost surreal appearance with a soft focus. One of the qualities of a pinhole photograph is that the foreground, middle ground, and background all have the same focus.

Contrast

Film photography with a Pentax 67 and a #3 Red filter. I used ILFORD HP5-400 black and white film. Because the filter soaks up 3 stops I metered with ISO-50 and settled on f16 @ 1/250. Developed at home in ILFORD DD-X developer.

So, how is your day going?

The cat got sick this morning.

While sitting on the pot I somehow managed to tinkle all over the floor.

I made coffee but forgot to turn on the machine.

When I got out of the shower I discovered I didn't have a towel.

And now for my next trick ...

The old phone still works

I connected the old Western Electric 302 rotary dial telephone up to my land line using a pulse to tone converter box. I was able to verify that the old phone still works. I used it to call my cell phone, then used the cell phone to call the old rotary phone. It works great!

Completion of a long project


This is an electronic weather station of sorts that I assembled from a variety of electronic parts and soldered together on a protoboard.

At the heart of the weather station is a HUZZAH 32 made by Adafruit in Manhattan New York. The HUZZAH 32 is an ESP32 microprocessor with WiFi hosted on an Adafruit Feather wing breakout board along with a USB connector, a battery connecter, a voltage regulator, and pinouts making the ESP32 microprocessor very easy to use. The ESP32 can be programmed using the Arduino IDE or Python.

I also added an Adafruit Ada Logger which is a Real Time Clock with battery backup and a micro SD card reader/writer. I am only using the SD card feature.

I connected a DHT22 digital temperature and humidity sensor. It is easy to use and works very well.

Then I connected a BMP388 pressure and temperature sensor. This did not work according to specifications but with some arithmetic I was able compensate for its error.

The really cool sensor is the PMSA003I air quality sensor that measures particulate mater in the air. It measures dust, smoke, pollen, etc. from 10 micrograms per cubic meter of air to as little as 0.03 micrograms per cubic meter of air.

Finally I wrote a program to pull it all together. The program does more than just read data from all the sensors, it also saves the reading to the micro SD memory card and makes the readings available via a web page accessible over WiFi.

It took much longer to develop the program than it did to wire and solder everything together -- which took several days.

I might eventually add a rain gauge and weather camera to it but for now I consider the project to be complete.

My oldest brother passed away last week

Frank Ross Hoadley was born November 3, 1944 to Joseph and Frances Hoadley in Saint Louis Mo. where Doctor Joe was finishing his residency. The family would relocate to Gillette Wy after Doc Joe finished his service as an Army surgeon.

While growing up, Frank enjoyed hunting antelope, deer and rabbits on the family homestead ranch south of Gillette.

Frank was schooled in the Campbell County school system and completed his senior year of high school as a foreign exchange student to Australia.

Frank continued his education at the University of Wyoming receiving a Bachelor's Degree in English Literature. Frank would stay on at the University for a few more years while serving as a campus police officer before taking a position as a detective in the Laramie police department.

Frank was later hired by the city of Laramie to work as the City Manager where he served for several years.

Always looking for new opportunities Frank took a position with Boettcher and Associates in Denver, Colorado.

Frank left investment banking to take up the position of Capital Finance Director for the state of Wisconsin where he would serve under four different governors from 1988 until his retirement in 2013.

Frank was very highly regarded by his peers and considered a standard bearer of state debt management. As Capital Finance Director Frank introduced a number of innovations including the introduction of extendible municipal commercial paper. He was a champion of strong issuer disclosure and plain language in financial documents. His leadership and guidance in the Government Finance Officers Association was very influential. In 2008 Frank was given a lifetime achievement award by The Municipal Forum of New York.

Congresswoman Gwen Moore of Wisconsin is submitting a statement honoring Frank Hoadley into the United States Congressional Record.

Frank is preceded in death by his father Joseph, mother Frances, and his first wife Myrna Crout. He is survived by his sister Jeanette, brothers David and Clyde, his wife Elizabeth, and daughters Marci and Jessica.

Frank passed away August 4, 2022 while vacationing with his wife in Scotland.

Hello 6502 world!

I've worked with computers for about 40 years. In the late 70's when I was in Tech school we learned how to write programs first on chalkboard then on paper coding forms. We submitted our programs on coding forms that were sent off-site and we would receive our results a few days later.

We also learned about truth tables, AND, OR, NOT, NAND, and NOR gates. In one of our labs we actually built an adder. We had to pool our breadboards together so we had enough space to build the circuits. We eventually got it to work.

I have a lot of fun playing with Arduino microcontrollers and Raspberry Pi microcomputers, but I've never built a functional computer from the bear-bones chip up. This changed after I discovered a YouTube channel run by a guy named Ben Eater.

His whole channel is devoted to building a computer from the wires up. After finishing his big project he is following up with a simpler project where he builds a computer from the chips up. I bought a 6502 kit from him and have been following along with the project.
