  • CAD is a bit like programming, there’s a lot of ways to do any given task. That can make it tricky if you are doing some tutorials that use one workflow, and then start doing tutorials that use a different workflow.

    If you want to learn it, do yourself a favor and take time to find a tutorial that goes from start to finish doing the type of project you want to do so you don’t get frustrated when you get midway through.

    Like others said, if you are used to doing something in a different CAD software, you might find that the same workflow is clunky in FreeCAD, but if you start out with a workflow that works well in FreeCAD, you are fine.





  • My dream is to one day have a setup like this. Like others said, humidity and heat in a greenhouse are 2 big concerns. They make all kinds of automated systems for opening vents, etc.

    If your primary goal is growing in a contained area to keep pests away (vs. needing to really keep the space warm in winter or something), you best bet could be a hoop house. Basically you can drive rebar or fence posts into the ground, and then arch something (pvc pipes commonly) from one side of the space to the other. You’d then pull plastic sheathing overtop. Those are commonly used to get growing started in early spring and extend growing in the fall. When it’s warm enough, they basically roll up the material. You could do something similar but still have a structure of chicken wire or netting or something to keep animals away.

    If you actually want to keep the space warm to grow in the winter, you might want more permanent walls with better insulation, like double walled polycarbonate.

    Another thing to consider is water. If you have a greenhouse next to your house, you don’t want rain that falls on it to direct water to your house’s foundation.



  • I love the look of repurposed windows/doors for greenhouses, and I’ve even seen them advertised for that purpose at resale shops, but it’s really important to be careful about lead paint if you want to do that. Lead was the primary white pigment for a long time, and since windows/doors are often trimmed white, if they are older than 1978 (in the US, EU was 2003, though many member states had their own laws previously), it could be lead. Lead testers are fairly cheap if you want to go this route.




  • Does anyone have specific recommendations for a light to use as a lantern?

    I have a good headlamp for hiking/camping/etc, but I’d like a little flashlight to use as a backup/as a stationary lantern around camp. I’ve never used a diffuser on a flashlight, so I’m not sure if they are all created equal, or if some are better than others. Momentary brightness isn’t that important to me, but decent efficiency, a red light, and light weight are important. Bonus points for using 18650 since that would make it compatible with my headlamp.







  • I think there’s only 2 ways to actually kill a cast iron pan. Dropping from a height that causes the brittle metal to break, or putting lead in it. Obviously no one puts lead in their cooking vessels, but small pots are/were used to melt lead to pour in bullet molds, so if you find an old used pot, it’s good to check for lead.

    Also, ceramic linings can get chipped.

    You can mistreat bare cast iron horribly, never seasoning it, washing it in the dishwasher, or whatever, and it won’t get irredeemably damaged.




  • Weather is global, so agencies like the NOAA collect data from satellites, weather balloons, weather stations, buoys, etc. all over the world. NOAA’s data is a bit like GPS: paid for by US taxpayers, but used for the common good across the globe. Shutting them down wouldn’t just hurt weather prediction in the US, it would hurt everyone. Other developed countries can absolutely predict their own weather, but if they can’t include the volume of data generated by the US, their accuracy will suffer (and obviously likewise if the US couldn’t use EU data or whatever).


  • On the weather front (lol) one of project 2025s goals is to break up the NOAA. They want to do it specifically to hamper the ability for anyone to show the ongoing effects of climate change. If anyone thinks this is a conspiracy theory, it’s an actual conspiracy, and here is the direct quote from project 2025.

    Together, these form a colossal operation that has become one of the main drivers of the climate change alarm industry and, as such, is harmful to future U.S. prosperity. This industry’s mission emphasis on prediction and management seems designed around the fatal conceit of planning for the unplannable. That is not to say NOAA is useless, but its current organization corrupts its useful func- tions. It should be broken up and downsized.
