Hi Ash, and welcome!

Apologies for the delay, I just finished moving apartments and was unavailable for several days.

Can you tell me or show me pictures of what equipment you have exactly? Do you have a version of the FBRC cell? The MYSTAT software can only control the MYSTAT potentiostat and an Arduino UNO R3 (used for controlling pump speeds). It can't be used with another brand of potentiostat at this time.

Hi Kirk,

Thanks a lot for your time and I hope that the moving process has worked properly for you. After trying and serarching more, I could get the app, and now I can run the cell correctly. But now I do have a new question: Is it possible to order or buy a new cell setup like what is in the website Flow4U Battery Conference (https://fbrc.dev/posts/Flow4U-conference/) ?

Best wishes
Ash

@a.rahimzadegan, right now the fastest way to get the latest version of the kit is to build it following the instructions at https://fbrc.codeberg.page/rfb-dev-kit/. We would like to sell them eventually but we're not there yet.

It is mostly 3D printable and there is one brass/copper plate that needs to be machined in a simple way, definitely no problem for any university machine shop. We also now have identified pumps/tubing that work much better.

Hi! I work at a technical university, in the mechanical engineering faculty. I'd like to build your prototype based on the documentation. Flow batteries are a new topic for me, but they could be very useful in my field, and this seems like a great way to get to know them better. I also saw your presentation on YouTube. I was about to ask about the peristaltic pump model, but I noticed you’ve just updated the documentation This forum looks really helpful in case I need any support or clarification. I’ll try to give some feedback if it’s useful to you.

[kirk]

Welcome @gus and thanks for joining! Please share any feedback no matter how small it might seem. Fresh eyes are really helpful.

The docs are close to being done but not quite there yet! I am going to check over them now, some small things have changed (e.g. gasket thickness is now 0.1 mm).

[kirk]

@gus the docs are now more up-to-date in terms of components: https://fbrc.codeberg.page/rfb-dev-kit/index_BOM.html (specific changes here: https://codeberg.org/FBRC/RFB-dev-kit/commit/0c7eae7fe7f829a2d11ad663948377c5c3419191#diff-6bf6300053fa6ad4798859a249550165c9a2ab8b)

[gus]

@kirk Thank you very much! Are the STL files (under Fabricating Components in the documentation) already up to date? In particular, are the holes in jig.stl compatible with the new pumps?

[kirk]

@gus give me a few hours and I will confirm this for you, I will make some changes to the jig.stl file that will make it better. The holes should already be the right size but I will double check.

[kirk]

@gus here is a new jig design. With the latest pumps, we don't need an external motor driver anymore, so the jig could become simpler. Now, the plan is to print an external Arduino case which mounts directly to the jig, reducing print time and the size of the entire jig.

Here are the latest instructions: https://fbrc.codeberg.page/rfb-dev-kit/fabrication.html

This should definitely fit the new pumps.

@kirk Thank you! I'm starting to 3D print all the components.

Hola , somos agricultores en españa, Mallorca, nos apasionan las tecnologías que ayuden a ser mas rentables las explotaciones agrícolas. Y una de estas tecnología creemos que debería de ser tanto el almacenaje como producción de energía limpia y escalable para poder ofrecer a la comunidad, aunque ya hay soluciones comerciales al respecto creemos que soluciones open source son las mas acertadas ya que sirven de contrapeso para no depender totalmente de soluciones "privadas" y en cierta forma hacer de palanca para que halla mas "competencia" en el mercado...... ademas lo open source es el exponente de una colaboración muy estrecha y normalmente apasionada , así como una forma de encontrar soluciones simples a problemas complejos mediante el ingenio colectivo......
Probablemente en los próximos años soluciones como las baterías de flujo sean una gran solución y si las instituciones laboraran una red de baterías de este tipo podría satisfacer y dar seguridad al sistema eléctrico "yo lo llamo el Internet de la electricidad"
en fin amigos . saludos de la huerta de pili "finca ecologica"

Good luck, please let us know how it goes!

¡Hola y bienvenido! I think we share a similar vision

There is another farm that expressed interest in the project in the Dominican Republic: https://vivavistadelmar.wordpress.com/2024/09/24/let-the-power-flow/

One of our main contributors, Daniel, is also based in Spain and can speak Spanish fluently (unlike myself).

It will be a while before we have designed a system robust enough for practical use in a demanding environment like a working farm, but we absolutely plan to get there eventually! See our roadmap for more details: https://fbrc.dev/posts/roadmap-faq-forum/#roadmap
