That's it. I'm out. See ya elsewhere.

Found a @sparkfun #OpenScale board in my parts bin, so I'm making a thing.

Tomorrow Jan 10 at 6:15pm is the next session for the @ISS_Mimic Community Build at @FreemanLib in Houston! Come help us build a 1/100th scale moving model of the International Space Station! New makers are welcome at any or all of the sessions! @harriscountypl

Hanging out at @TheIonHouston this morning for a #CupOfJoey to learn to be a people person.

Just a typical "do some soldering while waiting for a space launch" morning. #Artemis1

@RachelRaygun - I'm also looking for LEDs with extensions like those in this video. Do you have some of these in the stash as well? I can't find them in mine.

@RachelRaygun - Do you have some of the beepers and push buttons in the JHLIL as shown in this photo? They're some more things I can't find in my stash for RPi classes.

Getting ready for @Region4ESC #RaspberryPi training at their STEAM conference on Friday. Still need some HATs and VGA adapters.

Hey #space Twitter: I see numbers in the $2600/kg range to put a payload into #LEO. Does anyone know how much it costs (will cost) to get into lunar orbit? Maybe @SciGuySpace, @Erdayastronaut, or @jeff_foust has a reference?

Lovin' all the additions and upgrades to the #ISSMimic model. I know there's a lot of love on the Mimic team for the SASA antennas, but I gotta say that they're not as iconic as the Ku-band antennas. It looks like some upgrades to JEM since I last saw it too!

@ISS_Mimic Looks great!

This new addition astronaut to #ISSmimic IS TO SCALE though... Notice the SASA antenna on Mimic?

If you're at #Comicpalooza2022 this weekend, be sure to check out ISS Mimic and geek out over #NASA and #space.

@ISS_Mimic The display looks awesome!

ISS mimic is live at #comicpalooza come check us out in the robotica section!

I know we're all here for the #JWST images, but I have to pivot for a moment and say that this here is bullshit. Sorry to see this happening. Clear Creek ISD superintendent hammered by anti-CRT parents announces resignation houstonchronicle.com/news/houston-t… via @houstonchron

We had a blast showing you #ISSmimic at #Moon2MarsFestival @SpaceCenterHou #MarsNotToScsle

@ISS_Mimic @SpaceCenterHou Looks great! Sorry I had to bail on the team.

If you were on station (ISS/Gateway/etc), what sort of functional widget would you consider #3Dprinting that you couldn't have brought with you? @AstroBehnken @Astro_Doug @astro_ricky @AstroRM @AstroVicGlover @astro_timpeake @AstroSamantha @Astro_Flow @astro_kimbrough @Astro_Boe

About to hang out with 10000+ of my #3Dprinting beasties. #RAPIDevent

Sunday morning experiment trying to cool air with a Peltier. I could improve the design, but the low thermal mass of air is a real killer. I knew that going in, so this was more of a 'for grins and giggles' project.

Here's a bit about what I've been up to lately...

Unfortunately, I don't know to whom I should attribute this, but I found it in a 2012 #NASA Thermal and Fluids Analysis Workshop (#TFAWS) presentation, and it rings so true to me:
