JacobCoffinWrites@slrpnk.netto Solarpunk technology@slrpnk.net•World's longest cargo sail ship launched in Turkey2·5 months agoSuper cool that these are actually happening! I read about them a lot while researching modern sail ships but it’s hard to tell if new tech like this is really happening until they build it.

JacobCoffinWrites@slrpnk.netto Buy it for Life@slrpnk.net•Is BIFL Still Possible Today?English17·5 months agoThrowing in a little odd advice for the secondhand scene - even if the shops are bad, I’ve had some good luck with estate sales and cleanouts (where a family or realtor basically opens the home to anyone who’ll cary stuff away and save them the trouble and cost of throwing it out). It can feel kinda bad, picking through stuff in that context, but we’ve saved a bunch of nice old tools and kitchen stuff that way, and the houses generally have everything else you might need for a house. Personally I think the best BIFL stuff is old and made before they really perfected enshitifying their products.
The cleanouts I’ve been to we found through postings on our local free groups (which I also really recommend) or word of mouth, but I used to know some folks who went to them professionally, looking for merchandise for their own businesses, so they must be advertised somewhere normal people would find them too.

But house boats have been around for a long time and when they’re someone’s primary residence they sometimes represent a cheaper model of living, not unlike a mobile home. An airship houseboat is an interesting idea, I think it showed up at the end of Cory Doctorow’s Walkaway.
JacobCoffinWrites@slrpnk.netto Solarpunk technology@slrpnk.net•Should Airships Make A Comeback?10·6 months agoTechnology and materials sciences have come a long way since the 1940s. For example, we can probably skip sealing the gasbag with solid rocket fuel. Hydrogen gets better lift than helium, it’s not a limited resource with higher-priority medical uses, and doesn’t require petroleum-style drilling. It’s flammable, as we saw in the past, but with modern engineering, modern materials, non-conductive pressure vessels, emergency release valves, no ignition sources or sparks in proximity, it seems like it can be done pretty safely.
Until recently, I think, modern aviation had been admirably safety-focussed, in everything from engineering to operation. I’m not a fan of the airline industry and especially Boeing’s recent shortcuts, but I think solarpunk is very much about picking and choosing which parts of our society to keep and which to reexamine to see if they can be done better. Aviation safety is one of those things our society does know how to do well, and that seems very much worth keeping to me. Overall I trust aviation engineers to find ways to do hydrogen airships safely.

I think I’d suggest starting with one of those, and once support eventually drops, if you’re comfortable with a reduced security capability, looking to lineageOS or similar. I think if Graphine supports a phone, it’s pretty much guaranteed to have support on the more general OSs.
For a while I looked at ruggedized smartphones (some with removable batteries!) that were supported by lineageOS and others. I didn’t find one I was convinced would hold up as long as I wanted, and I had security concerns so I ended up getting a decent secondhand phone with guaranteed security support for a few years and putting it in a good case.
Sometimes I check in on various raspberry pi smartphone projects. I love the idea and think it’d probably be able to last the longest (or be turned into something else after an upgrade) but I don’t think any feel reliable enough to me yet.

JacobCoffinWrites@slrpnk.netOPto Solarpunk technology@slrpnk.net•hoping to build a list of car parts that can be used for other things4·10 months agoThanks, that makes sense on both topics, they’re definitely going on the list!
JacobCoffinWrites@slrpnk.netOPto Solarpunk technology@slrpnk.net•hoping to build a list of car parts that can be used for other things4·10 months agoThat’s a good list, thank you! I have a couple questions you might be able to answer:
Could you elaborate on the relays? I don’t know anything about them yet (in their intended use or alternatives). Though I am reading up on them.
I know there’s a some benefit in running 12v appliances (intended for campers) with solar panel setups because you don’t have to convert from DC to AC then back to DC at the appliance. Would that work for just using a car’s AC unit to cool a room, or are they built too specific to a car or not efficient enough to justify the work?
Thank you!!
JacobCoffinWrites@slrpnk.netOPto Solarpunk technology@slrpnk.net•hoping to build a list of car parts that can be used for other things2·10 months agoThat reminds me - inside the rubber squeegee part is a long thin strip of good quality spring steel. Lockpicking folks like it for making tools, diy gun folks sometimes use them to make the extractor. I honestly don’t know what to use the rest of the wiper for.
JacobCoffinWrites@slrpnk.netOPto Solarpunk technology@slrpnk.net•hoping to build a list of car parts that can be used for other things5·10 months agoThis is a great list with a bunch of stuff I wouldn’t have thought of - the transmission reuse is a cool idea!
I think some LED headlights are goood for growing plants. I remember some local news panic piece from years ago about how criminals were stealing headlights for their grow ops. A quick search online confirmed they work fine (probably not worth stealing though) and this post I think suggested a couple other car parts alternative uses I’ll have to go back and get later: https://www.rollitup.org/t/is-it-possible-to-convert-a-headlamp-into-a-grow-light.496815/
Thanks again!
JacobCoffinWrites@slrpnk.netOPto Solarpunk technology@slrpnk.net•hoping to build a list of car parts that can be used for other things3·10 months agoThat’s a great example, thank you!

I think getting solar coolers into form factors compatible with how kitchens already operate could be a huge step towards adoption of the tech. It’s part of why I really like (this slightly simpler design)[https://solarcooking.fandom.com/wiki/Scheffler_Community_Kitchen]. I think the convenience factor in systems like this, where the cooks can operate basically as if it was a conventional oven, is great
JacobCoffinWrites@slrpnk.netto Solarpunk technology@slrpnk.net•What Solarpunk Tech do you own?3·1 year agoMovim is awesome! PoVoq put a bunch of work into getting it set up and linked with Lemmy so if you have an account here, you can just start using the microblogging platform too! I use WordPress for my art and writing and Movim for my making-and-fixing-type projects, and I mostly prefer Movim - the interface is nice, it’s free, doesn’t spatter everything I write with gross ads, and it’s not corporate. I’d very much recommend it.
JacobCoffinWrites@slrpnk.netto Solarpunk technology@slrpnk.net•What Solarpunk Tech do you own?6·1 year agoThanks! I pulled it from one of the more popular solarpunk flags. Out of all the ones I’ve seen, many of which feature the sun-and-gear motif in some configuration, it’s my favorite symbol for the movement; It’s very simple and visually clear, and easy to render with one color.

JacobCoffinWrites@slrpnk.netto Solarpunk technology@slrpnk.net•Self-balancing commuter pods ride old railway lines on demand3·1 year agoIn the northeast there used to be a fair bit, but I think a lot has been torn up in the process of making bike paths. A lot of the small towns I grew up in still have intact tracks running between their centers, I’d love if these pods made an appearance, if only to show folks that trains can be useful to them.
JacobCoffinWrites@slrpnk.netto Solarpunk technology@slrpnk.net•Self-balancing commuter pods ride old railway lines on demand3·1 year agoMan I wish our trains ran anywhere near that constantly. They stop the public transit around midnight in my city, but that doesn’t stop it from being tremendously useful during the rest of the time. You learn to plan for it, and advocate for improvements whenever you can

Lore might be a good candidate - one narrator relaying stories from history that are dark or spooky in one way or another. It’s quite fun and well-produced.
https://www.lorepodcast.com/
Be warned that he approaches history from a folklore standpoint and will sort of tell you the spooky story version of what happened and how it impacts modern day pop culture - so if you compare one of his (fairly short) episodes on a well-docunented famous murder or something to a deep-dive series or book on the subject it will be missing information.
