pedestrian cyclist

What kind of bicycle would people ideally use in a post apocalyptic future? Suspension and gearing - probably? Electric - might also be useful, but even harder to maintain than the other two?

I'm kind of intrigued by this bicycle by Rick Hunter. Looks pretty good for places where roads aren't repaired any more. (Also bike paths of Berlin...)

Finally A Small Affordable Electric Right-to-Repair Enthusiast Utility Vehicle

lemm.ee/post/62463387

lemm.eeFinally A Right-to-Repair Small Affordable Electric Utility Vehicle - lemm.eeThe best daily transportation isn’t a car/truck at all, but there is still some freight/hauling needs to be done. Something about the minimal options and practicality of manual roll up windows feels solarpunk to me. I mean, current trucks (even Rivian): - brag about their 0-60 instead of practicality/utility - are extremely anti-right to repair (especially Tesla) - a privacy nightmare - getting larger every year - have pretty high prices across the board - are absolutely crammed with manadory luxury features like air conditioned seats or motorized trunks This truck seems to be the opposite. I bet, in less than 1 year, hobbyists will get a solar panel array mounted on one of these. And with the truck being so fixable, maybe we’ll have these things be like those +100 year old tractors that just keep getting fixed.

Mañana voy a dar una charla sobre Collapse OS en la FLISoL Montevideo 2025 en el Espacio Colabora a las 11:35hs

Resumen:
Nuestra vida cotidiana está absolutamente permeada y atravesada por la tecnología y se sostiene gracias a que se satisfacen muchas condiciones que hoy damos por sentado, como la energía, recursos minerales, cadenas de suministros, etc. ¿Que pasaría si alguno de estos factores que determinan el devenir de la civilización moderna, se interrumpiera o fallara? Algunos autores plantean que la civilización moderna simplemente colapsaría. Collapse OS es un proyecto de un sistema operativo para dispositivos de 8-bits programado en FORTH con la intención de poder reiniciar la tecnología post-colapso, devolviendo la posibilidad de programar micro-controladores y otros dispositivos imprescindibles para la vida moderna, como un panel foto-voltaico, o el riego automático de una huerta. En esta charla presentamos el proyecto, sus argumentos y sus resultados, mirando con el ojo latinoamericano y viendo que preguntas interesantes nos plantea y nos deja, en el marco de nuestra relación con la tecnología.

Sugarcrete: Annopen access, eco-friendly and remarkably effective building material

slrpnk.net/post/21314742

slrpnk.netSugarcrete: Annopen access, eco-friendly and remarkably effective building material - SLRPNKAt Panchsheel Inter College in Uttar Pradesh, students now study inside a new school wing built not from concrete or traditional brick, but from sugarcane. The innovation was born at the University of East London (UEL) and its creators argue it could reshape how buildings are made and how the planet pays for it. Sugarcrete combines the fibrous residues of sugarcane, called bagasse, with sand and mineral binders to produce lightweight, interlocking blocks. Lab tests show that Sugarcrete has strong fire resistance, acoustic dampening, and thermal insulation properties. It’s been tested to industrial standards and passed with flying colors. In terms of climate impact, the material is a standout. It’s six times less carbon-intensive than standard bricks, and twenty times less than concrete, by some estimates. Yet the real excitement doesn’t only come from what Sugarcrete is, but how it’s made and used. It is purposely ‘open access’ in order to establish partnerships to produce new bio-waste-based construction materials where sugarcane is grown. Unlike conventional building materials locked behind patents, Sugarcrete can be made by anyone with the right ingredients and basic manufacturing tools. That choice decentralizes construction innovation, allowing small-scale producers — especially in the Global South — to lead.

Tinker ☀️

The Kratky Hydroponic Lettuce Wall will be comprised of a couple of things:

1) A utility shelf with adjustable shelving
2) Full spectrum LED "grow" light strips w/ timer
3) Grow bins

That's it.

The utility shelf can be broken down into the following requirements:
- DANGER!!! WARNING!!! IMPORTANT!!!: The shelves should be able to actually hold the weight of your grow bins. Water is heavy. Many shelves by themselves cannot support the weight of the water and will need support. So check the weight rating on the shelves you get. We'll continue to talk about this further as we built out the shelf.
- ANOTHER DANGER!!! WARNING!!! IMPORTANT!!!: You need a way to anchor your shelves to the wall SECURELY!!! You don't want this thing tipping over. You build it too high and it falls on your kid or dog or cat and they may die. Secure this to your wall. Especially the higher you build it.
- Shelves need to be adjustable to allow enough space for the bin to sit and for the plant to grow
- A way to attach the light strips to the shelf above the grow bin
- Bonus: Make it pretty

The Grow Light Strips can be broken into the following requirements:
- They should fit the length of the shelf you pick and be attachable to it in some way
- You should be able to control them with a timer (either on the light itself or set up with a wall socket timer
- Have a method of increasing the light or decreasing the light (easily add more light strips if needed, or adjust brightness, etc)
- Be full spectrum "grow" light. Note: it does not have to SAY grow light. Sometimes lights are like cakes. A regular white cake is cheap. Add the name "Wedding" to that same cake and it gets expensive. As long as the LED light strip generates enough light for a plant to eat, we're good.

The grow bins can be broken down into the following requirements:
- They should hold water.
- They should be fully opaque and not allow any light into the bin itself.
- They should hold some sort of grow medium to allow a plant to grow on top and provide access to the roots to get into the bin to access the nutrient water
- Bonus: Make them pretty

That's it.

No pumps.
No aerators.
No central reservoir.

Just a place to put a kratky bin and grow lettuce.

We'll tackle how to size and shop for a utility shelf next.
