The guys at Flow Battery Research Collective have been designing a Redox Flow Battery development kit that you can build yourself using a 3d printer and a few tools. It's a desktop size flow battery that you can use to either do your own research, e.g. on different electrolytes or just to replicate their experimental findings.

Redox Flow Batteries have the potential to become grid scale or home electric energy storage solutions that are way better for the environment than current lithium based batteries. They can often scale power and capacity independently and allow for repairs.

The FBRC project wants to spread the knowledge on RFBs and help kickstart a global community that develops sustainable energy storage technology in an ope source fashion.

Beware that the project is still in its infancy and sourcing the materials can be a bit of a challenge. Be sure to ask around in the forums for help!

A gap in the pdf or actually a gap because you took years to figure it out? Both interpretations are funny.

A new community where people can just vent about or actually do coordinate action against the pest of ultra bright LEDs.

Converting an old marble table to a coffee table. I haven't worked in my shop recently and forgot how much work even the most basic thing like cutting to length is. Anyways, I'm happy how things turned out.

Dart case (lemmy.world)

I made a case to protect my darts when taking them somewhere. Here are some more images. The case was made to fit a specific model and it's not very parametric till then end, so I'm afraid it's not super useful for others.

It was made in #FreeCAD 1.0 which was super smooth!

Hah, I didn't mention the most important part. It basically switches on a ventilator when the absolute moisture content outside is lower than inside. This results in drying of the room that you ventilate like a basement with moisture issues. The dew-point acts as a proxy for measuring absolute moisture content.

I'm designing a case for a dew-point ventilator controller to be 3d printed. The controller is implemented using arduino on an esp32. The project is based off of the code and HW implementation by Make Magazine Germany: https://github.com/MakeMagazinDE/Taupunktluefter. When starting out I was thinking this would be an easy project but it turned out that especially the lid with its lip and groove design and the parts fixations were not that easy. I'm excited to finally print it.

The file is parametric to some extent and the main footprint is based off of a master sketch. Many parts were imported as step files from grabcad. I used FreeCAD 1.0-rc1 which works like a charm for many things. Next thing I would like to do is to use the new assembly workbench. What do you think?

Manual "Exploded view",

Opaque view.

Nobody knows who responded here. Don't spread rumors.

I'm not sure you understand. There is a mute functionality in Meet and there is one in iOS. This is so that you can have different apps with different states of mute. The OS level control is there so you can mute the mic for all apps at the same time.

KDE Connect is amazing. Also works without KDE.

FreeCAD is an amazing project, going at a pace similar to Blender some years ago. I foresee a bright future for it! All hail FreeCAD!
