Hi everyone.

So I saw a video a while back that demonstrated the effects of rich iron sources on the growth of the Algae Spirulina, in which the iron led to hastened growth and increased culture density. So, I wondered whether the same principle held true for Chlorella (Spoiler: It did!)

Despite being simple and making use of abundant materials, sand batteries are paradoxically an emerging tech, that's only just started being utilised at some scale.

Through the link below, I explain sand batteries in more detail, and try to build a small one myself, as it's an area I want to explore further in my research.

I think the tech has great potential as a low tech, scalable, sustainable form of energy storage.

Hello. I've just noticed this outstanding project, I think they fit OSE's principles very closely:

However, for true decentralization to be possible, the ideas and abilities must be learnable. Many modern technologies are too complex to be learned and practiced by communities, and are instead bound to industrial modes of production, creating a class divide between “developers” and “consumers”. These complex technologies will never be decentralizable, and any attempts to decentralize them will fail.

So, we have a lot of hesitation about putting anything on the internet basically, so we put most of our outreach into in-person things — getting people to come in and actually be face to face with us. Learning from each other face to face is so different from learning from each other on the internet.

Hi Everyone.

Algae cultivation has always been an interest of mine, ever since I heard about their applications in biofuel technology. There are many different species of Microalgae and one of the most promising with regards to biofuels is Chlorella. While Algae based biofuels might not make sense from a volume perspective, algae itself can be grown anywhere with the right environmental conditions, even in indoor spaces. And, if natural light is used, and it's scaled up to compensate for the energy cost of air pumps, it could provide a powerful carbon reducing feedstock not just for fuel, but for many other things, including foodstuffs and organic fertilisers (due to their typically high nitrogen content).

In the video linked below, I detail how I started my most recent algae culture, and how I learned from previous mistakes. This method is replicable to anyone who has the time, resources, and can get their hands on a starter culture (something I may work to resolve in the future!).

Hi everyone!

My academic journey is about to end and I need to write my final paper to finish my degree. I would like to write about ecological crime but in my language I cant find a lot.

Does anyone have a recommendation which crime to write about? English is not my first language and it would be helpful if the crime in question would be highly documented and media covered so that I wouldnt struggle to much with finding data sources.

Thanks!

Transparent forest data is key to effective climate action! The FAO's CBIT-Forest project, in collaboration with UNDP, is empowering countries to meet the transparency requirements of the Paris Agreement by enhancing the collection, analysis, and sharing of forest data.

Hi everyone!!

For the past few years I have been studying, building, and documenting a new version of the D3D Pro 3D Printer based on Open Source Ecology's prior art. I wanted to post the documentation here that I have completed so far (still a work in progress).

Here's a link to the website version of the documentation: https://alexandrialittle.github.io/d3d-pro/

Here's the link to the source of the documentation (which is accepting pull requests) https://github.com/AlexandriaLittle/d3d-pro

Here are some photos and videos of the build: https://photos.google.com/share/AF1QipO1XlRq2MeO1X1idXfgvzrbPz2ozq8t9KZZMXAqVvah1MqOsn6VbolkMdVK6x30Iw?key=WXJrZ25La1l1SDNoMUNtOVhvUHJ1eGVXV2RTTGt3

Thank you for taking a look!

Hi everyone.

Modular design, and design for dissassembly in general, are things I feel are crucial to transitioning to a more sustainable world. So, I thought I'd discuss the current state of how things are made, and how they could be made differently, to make them more repairable, recyclable, etc.

For people into 3D printing, I also thought I'd summarise a few tips on how to make your funcitonal designs more printable on a typical FDM printer.

I am looking for contributors for a new open source project I have just started. The goal is to create a versatile library that includes several frontend components. Currently, the project is in its early stages, actually we are 6 developers.

Why you should contribute:

1. Transparency: I am currently the only developer, and I do not use "we" when it is not appropriate.
2. Freedom: I will not continually ask you to contribute; if you like the idea, you are free to participate.
3. Simplicity: It is a project without bureaucratic complications. You are free to contribute as and when you want.
4. Open Source: The project is completely free, and any contribution is welcome.
5. Beginner-Friendly: The project is super-accessible

Greetings all.

Modularity is an important part of sustainable design, when it's relatively easy to assemble and dissasemble something, it makes it easer to repair, and to recover and recycle individual components at the end of their life.

Modularity is also the spirit of the design I am showing here today. Using my coil-holder design I call 'ModuCoil', I have created the version 2 of my ModuCoil generator. I hope to use this not only as a demo for modular design, but also to expment with, in a few areas from small scale wind, to energy storage and more.

If you want to find out more about this design, here's a link. You'll also find, through here, the STLs on my thingiverse page.

I tried using the Meilisearch search engine for our product but faced issues while syncing with my PostgreSQL database. I used a tool called Meilisync, which is suggested by Meilisearch, but it didn't work properly. Finally, I built a solution using Golang. Has anyone faced a similar issue? You can read more about my implementation here. https://journal.hexmos.com/we-chose-meilisearch-over-10-other-search-engines-despite-a-major-drawback/

I have a 4 year old laptop. It used to be very slow and hangs often. I had 4GB RAM, AMD Pro processeor. Recently I upgraded 500gb hdd as secondary and 256gb ssd. It significantly improved the performance. I always wanted to contribute to open source projects. After the upgrade of ssd, I tried to locally setup and run an open source project. But it hanged (Not responding).. Until I closed Vs code. I use Ubuntu most of times for my development work. And use windows 10 normal. I am interested in contributing to Web development based projects(JS, TS,..)

To run any open source projects locally and to contribute, what should I upgrade in my laptop? Is upgrading 4gb to 8gb RAM will be enough?

Wind tunnels are handy devices that are used extensively in the renewables and aerospace sectors. They provide a consistent, laminar air flow source that can accurately and fairly measure the performance of wind turbines.

Hence, I have decided to design and 3D print my own Wind Tunnel, so that I have a fair test apparatus for any Wind turbines I find or design, and eventually print.

Follow the link below to learn more about my wind tunnel. STLs are available in the comments.

I have a still so I end up with lots of waste alcohol at around 80%. Anyone develop a simple burner to heat a greenhouse or shop?

I tried to find a suction cup that would work on rough surfaces (similar to sandpaper like finish) but found no luck.

As a result, I would like to build my own with a mix of 3D printing and various other materials in combination.

At the moment, I plan on using a TPU compressible “accordion” like shape, that will try to expand volume after placing the device against a wall in order to create suction. Further, I plan on mixing and pouring my own silicone that will be attached to the end of the suction device as an interference layer to the wall. The point in mixing my own silicone is you hopefully get a good balance of softness/malleability to conform to rough surface creating seal alongside rigidity for durability.

All this being said, I am unsure how well this solution might work, and am wondering if there would be potentially easier or better solutions available (not afraid of a little hard work).

Any help at all would be greatly appreciated!

Hello all,
I am currently a student in Computer Science and for my thesis I want to do a case study focused on the migration of on-premise applications to Oracle Cloud. The goal is to illustrate the entire migration process, challenges encountered, solutions implemented, and the broad spectrum of benefits achieved through migration.

What I am looking for is an open-source web application, ideally developed in Java, C#, or Python, that I can run locally for some initial analysis. Afterward, I plan to migrate it to Oracle Cloud to observe and document the differences in performance, costs, operational efficiency, and any other noteworthy metrics.

Any suggestions would be much appreciated.

Thanks

I have had this idea for a while now since I love vintage and been scanning vintage photos as well as some ephemra over the years and know there are other people who do the same thing and public domain sites/sources out there.

I also have my own photographs, videos, audio files i would like to share with artists and creatives

so the idea is to have a open source kind of place where artists/creatives can upload and use things for what ever they would like. so say i have an audio clip of water and a audio tech needs a water sound for a video or a graphic he can go and download it from the site.

​

if this kind of this already exists or any thing like it let me know. intrested in it. I have 100s of GBs to share
