Maybe change your situation.

Amazing! I'm happy to hear I could recruit someone on Lemmy :)

You can get them in the size of 500g or 1kg. I'd be happy to share from my stash if you live in EU.

This place needs a few trees :)

This is where I document my build. I'm updating frequently at the moment.

[–] callcc@lemmy.world 6 points 1 week ago (3 children)

I'm building one and am super excited. Unfortunately I need to waid for some more parts to start experimenting.

You need Polypropylen filament for printing, graphite felt as electrode, grafoil gasket material as bipolar plate, brass plate as current collector (cut by cnc), silicone gasket material and a measurment device like a potentiostat.

If you're really interested, living somewhere in the EU, I could send you some stuff. I also have the chemicals in big quantities.

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!

Panama Jack I think.

[–] callcc@lemmy.world 2 points 2 weeks ago

Probably it's new AI based layout engine.

[–] callcc@lemmy.world 2 points 3 weeks ago

It's more against the rain. Although some shade might be helpful too.

[–] callcc@lemmy.world 2 points 3 weeks ago (2 children)

Are they covered? After two seasons of pure endrot I bought a shabby little "greenhouse" to grow my tomatoes in. Fingers crossed for this year.

Don't recommend using FTP. It's a shitty old protocol that needs to die. Just use nginx or apache with directory listing enabled.

 

So every time I drive my little car at night I'm filled with ungealthy rage afterwards and every time I think about what possible actions to take. This time I swore that I'd share some of my thoughts in order to help the movement gain more momentum. What comes is a collection of more or less well thought out ideas, don't take them too seriously.

  1. This is not really a political fight, it's about making the world better for everyone. We don't want to take away anything from you. We should try to not get the majority of people into a defensive position but rather educate about the problems and changes in lighting.
  2. Words are powerful. We need a word or wordmark that is easily understandable and that has a negative connotation without being too confrontational (like fuckyourheadlights).
  3. We should be cleverly about our strategy and take into account mass psychology. A big proportion of people have annoying headlights but either don't know it or maybe don't know how to make them less annoying. Make it so that the don't feel like they are the enemy but rather part of the solution.
  4. We should use official petitions or similar direct democracy tools if you have them in your country. Be clever and don't blindly start one. First gather a group of people willing to support it and have a good plan. Don't be confrontational, maybe ask for official investigation instead of bans.
  5. We should try to have science investigate the issue from a psychovisual point of view. This is all about people and not dry measurements and badly done specs. Try to include drivers eye-level and cars headlight height into the studies. Include spectral issues. White light can have a very different effect than more yellow or reddish light. Petitions could urge for scientific studies instead of bans or direct changes in policy.
  6. Include bike headlights, they are often as annoying as car lights. This issue highlights the alignment and height offset as parameters to the annoyingness and allows die hard car users to be included in the fight.
  7. The headlights issue is an issue for people in all groups of society. Be inclusive and use all kinds of platforms or media channels to spread the word. Be sure to consider 2. and use a common branding or word mark so small communities find their ways together into a big movement.
  8. Create songs, images and jokes to raise awareness of the topic. Don't point fingers but maybe make fun of people who have too bright beams without excluding them.
  9. Create material to help people to better align their lights or maybe dim them. Experiment with applying transparent foil to slightly reduce strength or change tint.
  10. Create a common signal to show other drivers that their lights are blinding. This could be for example: two short flashes and one long. Include this signal into your propaganda material. On bikes, remove your light and point into the eyes of the other biker until you have their attention, then point on their light. They will mostly understand the issue (unless they are dumb :/).

I hope to have brought up some interesting points for further discussion. What do you think?

 

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

 

Someone made this nice protest song!

Blinded by the light (and not in a cool way)

Contact me if you want an mp3 or similar.

 

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.
