I have an indoor/outdoor thermometer to keep track of how hot the back of my Expedition gets. I drive pretty regularly with two dogs in the back, and over the summer and winter the temps can get a little extreme.

I need to be able to take it out to keep an eye on it remotely (it has about 1/4 mile range) but also have it not rolling around while I drive.

There was a coin holder there that I popped out, and used as a template for an insert to keep this mounted semi-permanently.

Printed with kinda crappy Amazon Basics PETG. If it holds up well, I'll reprint it with better quality black PETG so it matches the car better.

Tips to keeping your identity secure, and protecting other members of your community from being accidentally doxxed or forced offline.

Extremely useful, especially for people who coordinate larger protests or online communities.

Neat time lapse video of a bunch of different plants (and fungi) growing from seed to flowering/fruiting.

We planted a variety of plants, at different stages of growth. After a bit of experimentation, cosmos grow extremely well. These were cuttings we put in just a couple weeks ago, and they're already bigger than most of the other plants that have been in there for over a month.

The very young plants did not survive, but the larger ones did. If they're too small, they just get swallowed down into the cups by the bobbing of the water.

Seems like the plants need to be large enough to reach all the way to the bottom of the pots, and still stick out enough.

Going to be interesting to see what it looks like at the end of the season.

Our retention pond in our neighborhood has a lot of algae and problematic plant growth due to the surrounding farms and lawn runoff, so we're experimenting with a floating island to pull nutrients out before they can cause problems. This will also provide some interesting flowering plants, and more fish habitats.

Will be an interesting experiment to see what survives and what does poorly.

Zinnias, sunflowers, marigolds, and a few others are in net pots, inserted into cutouts in EVA foam mats.

Really important step towards expanding our research on the moon, is creating highly detailed maps of the entire surface.

China is doing some great work on building out infrastructure and studies of the moon. They're the only country that's brought back any moon rocks in decades.

Space Race 3.0 is on, and we'll see how different approaches to the research and manned missions will move forward.

The US is currently building out an extremely upfront cost heavy project, but with a lot of long term benefits.

China is building a more straightforward moon project, but with higher ongoing costs, as much of the infrastructure is disposable (more like Apollo).

Pretty interesting topic, would be interesting if it could be used to move satellites to a "parking orbit" once they run out of fuel. It's unclear just how much movement in an orbit that can be done, as it says it needs to be in the same energy level.
