I went and did it. Made a longer-form video explaining our open-source battery project and diving into the details of the kit and chemistries we're working with!

It would really help our project out a lot if you could share this with interested folks.

Please let me know what you think, comments, criticisms, suggestions---first time I've made a video like this and I have a lot to learn.

@kirk nice. Thanks for showing us all the things, including the fails!

Really hopeful we can find a simple, cheap, storage solution that is enviromentally neutral and not dependant on questionable material supplies. Iron flow cells seems like a great possibility..

Music is a bit cheezy 🤣

@Slash909uk I'm not surprised you feel that way about the music given your profile picture 😅 I was tried to find a neutral CC-licensed clip... maybe next time I'll lean into it more and go with a track I found called "Corporate Jazz" just to take the piss

@kirk 🤣🤣🤣
Now I have to find that 'Corporate Jazz' track...

(The profile pic is my last works band Christmas gig, bunch of 80's & 90's covers. Lots of fun but far too long ago now.)

@kirk is there a write up on this somewhere?

@kirk Oh nice, diving into video is a whole other rabbit hole. I'll check it out; always interested in the nitty-gritty of battery tech, especially with how crucial it is for mobile. Making that first long-form video is a huge hurdle to clear, congrats on shipping it.

already found a mistake where I randomly left a thumbnail with my goofy face on the top video track for 5 seconds🤦‍♂️ oh well lol

@kirk I'd personally almost always fade the audio out. The transition at https://youtu.be/xhWBX1eLDr8?t=776 seems jarring.

I use sox but you probably use something integrated to work on both audio and video. https://sourceforge.net/projects/sox/ , packages in Linux distro repositories are named sox.

Very nice, crisp and to the point video!

@cohentheblue thank you! I actually changed the audio track at the last minute and had the fade enabled on the old one but forgot to re-add it :facepalm: I don't think I can fix it in YT, on PeerTube I can

And I am using @kdenlive !

@kirk

Any battery research is gonna make the energy shock better, especially since a ridiculous amount of production and transport relies on diesel. Decentralization helps.

How reliable are the tiny pumps, or more accurately the pumps that would be used in a later, larger scale model?

@cohentheblue these tiny peristaltic pumps are only for R&D, they are not efficient but cheap and we can replace the tubes when they wear out.

At scale centrifugal pumps are required. I am starting to experiment with some chemically-resistant magnetically driven centrifugal pumps for the 175 cm2 cell, but I imagine the lifetime is a function of price, and we are starting on the low end of course. But centrifugal pumps can go for quite a long time and can be serviced.
