It’s fall in the Twin Cities and the views from my window have been sublime, as is the usual this time of year. Biking will soon end for the season. That saddens me. I am already looking forward to spring. #minnesota #fall

It’s been a very busy few weeks for me! I’m pleased to be back on Mastodon. St. Paul received a fair amount of snow recently, so I shall post a pretty photo from the neighborhood. #snow #minneapolis #stpaul

Most “normal” people have clothing stacked/hanging on their exercise equipment. Right now, I have 3D printers stacked on top of my stepper machine. I am (not) normal. #3dprinting

I saw many posts asking for pictures of pets tonight. #StormyTheBudgie is happy to pop into your timeline this evening! Stormy’s not feeling 100% though. Molting is never fun, but the cycle is nearly over. My sweeper has been working overtime!

Greetings all! For those of you who play #pokemongo and would like to (occasionally) receive gifts from the #minneapolis and #cleveland areas, feel free to add me. I’m not all that active on the game, but I usually throw people a gift periodically. Code: 2280 7210 1207

View from my office window this morning. It’s been snowing for several days now. I guess winter is officially here in the #stpaul and #minneapolis region!

The view out my window this morning! Snow has arrived in the #stpaul and #minneapolis #minnesota area! I believe this is the first Winter Weather Advisory of the season! And… I’m curiously eager to #bike in it this evening!

Something simple I threw together for #SundayPixRedThings ... an animated GIF of three time-dependent functions plotted in RGB space.

It looks much better in 1920x1080 resolution, but server storage and download times must be respected!

Everyone, meet my feathered friend, Stormy. #StormyTheBudgie You’re going to see much more of Stormy in the future. For the few of you who choose to follow me, hopefully the weird hashtag will help you find other posts with Stormy and my birds later, if you are so inclined. For now, Stormy says “Good Night”. It’s been a long day. #parakeet #petbirds #birdsofmastodon #birds

This evening, I’ll share my first #BikeTooter post. I mostly ride my Trek Verve 3 in the neighborhood. I also have a road bike and an e-bike. Perhaps I’ll share some more scenes from my rides around the #minneapolis and St. Paul, MN area. Alas, that’s for another day!

Let's start out with something fun! These images show FFF and SLA #3dprinting printouts of a high-resolution T1 #mri scan of my brain. I created them using some basic neuroimaging software, 3D modeling software, and my scan data. Some research labs make such prints as gifts for their #neuroimaging study participants. I already had my data from trial runs of our studies.

The (somewhat transparent) model was done on an SLA (resin) printer at about 40% actual size. I'm planning to do a life-size print eventually, but the printer is too small to hold my brain, so I'll need to print one hemisphere at a time and do some hand tool work.

The other two prints were done on an FFF 3d printer at life-size scale using glow-in-the-dark filament (a real kick at halloween to decorate with glowing models of your own brain).

I teach a technology innovation course for first-year business students and I love taking these models in after talking to them about 3D manufacturing and its applications (particularly in medicine). It is also fun to show students my T1 and fMRI data and say "here's proof your professor has a brain!"
