A few #Solarcan harvests from (or near) the #wintersolstice
1. 2nd Floor classroom at Appleton East, looking south. Late Aug - Dec 19.
2. SE, installed Sept 29 and removed Dec 18. This was the best exposure, showing leaves on the tree for a little while
3. South, Oct 19 - Dec 21

At State Dept., a Typeface Falls Victim in the War Against Woke

Times New Roman is a slightly more narrow font (that’s an economy thing - less printing is more money for a paper) than Calibri, so the State dept. is actually conserving space and reducing printing. So that’s win for the environment, right? www.nytimes.com/2025/12/09/u...

I found a 5 pack of #Solarcan from one of their first production runs, so I installed this Solarcan, serial #562 (normally the ones I buy are in the #30,000 or more) for a few weeks in the spring - just to see if it was still good.

3 #Solarcan were installed at the winter #solstice '24 at #lawrenceuniversity #Bjorklunden in Bailey's Harbor, WI. Collected after the summer #solstice

The first is looking south at the Chapel. The second is facing the solar array, and the last one is in the woods near the solar array.

These two solargraphs came from an installation at Valley New School, looking East and South on College Avenue in Appleton, WI, installed around the spring equinox and taken down in May. #pinholephotography #solarcan #equinox

Here are a few Solarcan images I haven't shared yet. The first batch were taken from the roof of three elementary schools (Berry, McKinley and Richmond) in Appleton - installed in early January, and taken down in May to share with students.

Here's a solargraph of the ravine at the bottom of Reid Gold course in #Appleton The #Solarcan was installed on December 21, 2024 and removed on June 18, 2025 - just a couple days before the summer #Solstice

With the summer solstice yesterday, I collected a couple of Solarcan installations I had installed near the winter solstice. Enjoy the solargraph - days get shorter for the next 6 months #solstice #solarcan

Opinion | The latest generational divide: How to hold a phone A breakdown of why young people insist on recording videos vertically — and why older folks hate it.

Not just power, but water too:
"...using GPT-4 to generate 100 words consumes up to three bottles of water — and even a three-word response such as “You are welcome” uses about 1.5 ounces of water."

The last image was overlooking the Mississippi river in Onalaska, from can #39,838. This Solarcan installation was slightly disturbed from a recent storm, and you can see the diverted angle of the sun's rays that show that the can was moved.

This image is from Appleton, can #39,806. The scan looked a little over exposed, so I processed it in black and white. The last image was overlooking the Mississippi river in Onalaska, from can #39,838.

Installing a Solarcan pinhole camera between the winter solstice and spring equinox is a unique time in the N hemisphere, with no leaves on trees and the sun isn't too high, so it gets fully captured on paper #pinholephotography #solarcan

The first image is from the Oconto river, from can #38,294

Here's a few @Solarcan Puck images from the windows at Valley New School in Appleton. They have some amazing views of downtown Appleton!

Funding for this project came from the Stan and Phyllis Thatcher Family Fund for STEM and the Dianne Catlin Lang STEM Innovators and Girls Leadership Fund within the Appleton Education Foundation

Blending a mixture of science, technology and a little bit of art, I wanted to share some of their results from 5th grade students at Janet Berry Elementary. We're going to do this again in May to see what changes spring brings.

I've been working with 5th graders in a few elementary schools to install Solarcan Pucks around the school close to the spring equinox (facing North, South, East and West). Then they learned how to process and adjust the images to show the path of the sun over the course of a few days.

Last night was perfect snowflake photography weather in Green Bay. From the inside of my windshield.

I see your cat and raise you one cat.

I did some reprocessing

6 month exposure of @solarcan over the solar array at Bjorklunden @bjorklundendoorcounty @lawrenceuni #solarcan #solstice

A few @solarcan results from around the front yard, back yard, and down in the ravine (with a Solarcan Nebula). Front and back yard were installed in September, and the Nebula was installed in the summer. All started with trees full of leaves, eventually letting in more sun in the winter #solstice

Happy Solstice! I've harvested a few @Solarcan installations and installed a few more. More to come...

Snow squall to sun: This was difference in pressure from last night’s low of under 750 mmHg when the snow squall arrived, to today’s sunny high close to 770

Alum Brian Bartel experiments with long-exposure campus views Brian Bartel ‘97, a science instructor and amateur photographer, developed a fascination with Solarcan, a method of shooting long-exposure photographs and capturing the sun’s journey across the sky.

Here's a story about #Solarcan photos I took at Lawrence University www.lawrence.edu/articles/alu... @solarcan.bsky.social @lawrenceuni.bsky.social

It was almost perfect snowflake photography weather earlier today. A little too warm and now too windy.
