I have a terrible el-cheapo 14" HP laptop that I bought from a big-box store a few years ago as an emergency replacement for a laptop that died on me on the road while visiting a customer. I literally went to the store 5 minutes before it closed, bought any laptop they had, loaded Linux on it at the hotel and transferred my files from the dead laptop overnight, then did my presentation the next morning.

The trouble is, that laptop is VERY Linux unfriendly. I've put up with it for years because I don't like to throw things away, but I just can't stand the regular AMDGPU driver crashes and the broke-ass wifi-cum-bluetooth Realtek chipset anymore.

So I'm on the market for a good Linux laptop. I'm not a demanding user - I use that HP laptop to edit videos and do CAD and I'm okay with it - I'm very comfortable with anything Linux and I can code my way around problems.

I'm really tempted to get a MNT Reform laptop: I like the LiFePo4 battery cells a lot, it's solid, it's open hardware, it has a trackball and I love trackballs, it's highly hackable, and I'd like to support the MNT Research guys. And I'm old enough and the kids have been out of the house long enough that money is no object.

But a couple of things are holding me back. Maybe there are MNT Reform owners here who could shed some light on the following questions:

  • I don't know much of the ARM ecosystem, and what to expect from what processor / SoC. So I'm thinking of going with the highest end RK3588 32GB / 256GB CPU module offered by MNT. Would this at least match the performances of my stupid HP laptop's Ryzen 5 CPU in terms of real-world performances?

    Or put another way: should I expect to take a hit when encoding my videos or doing big CAD models compared to this already slow laptop, or can I reasonably expect the MNT Reform to at least not be a regression.

    Side question (yes, I know it should be obvious, but asking is better than guessing): I assume the "32GB / 256GB" in the CPU module's denomination is for 32GB of RAM and 256GB of onboard flash. Meaning I'd have that much disk space without needing to add a NVMe SSD card. Correct?

  • The keyboard layout looks all shades of terrible. I'm flexible with anything but not keyboard layouts - and especially those keyboard that don't put the left SHIFT and CTRL at the bottom where they belong, or have a split space bar.

    The Reform's keyboard ticks all the wrong boxes for me in that respect: I can tell rightaway that it's going to fight my typing muscle memory all the time and forever, because I sure ain't gonna get used to it.

    Can I remap the keys so I can at least I can swap CTRL and whatever that key is at the bottom left, and make the 3 buttons that replace the space bar act as a space bar? Then it's just a matter of putting a sticker on the keys and gluing the space bar keycaps together somehow.

  • I seem to recall some years ago that if the laptop was left off and unplugged for long enough - like 2 weeks IIRC - it would drain the cells and kill them because there was no under-voltage protection. Less dramatically but equally annoyingly, you couldn't leave it unplugged for a few days and expect to find it fully charged when you needed it most.

    Does it still do that? Or has the hardware been fixed - or maybe there's a "Turn really off" option in the little side computer that runs the mini OLED display?

    Mind you, I can always drill a hole and add a physical switch to disconnect the cells, but I'd rather not do that.

  • Is there an option to limit the charge? Keeping Li-ion cells constantly at 100% (or worse, charging all the time) when the laptop is plugged in isn't ideal. I'd rather it kept the cells charged around 80% . And I mostly use my laptops plugged in.

  • Can I remove the cells and use the laptop plugged in? I might eschew the cells altogether, because I really never need them: I'm plugged in at home, I'm plugged in on the train, I'm plugged in at the hotel, I'm plugged in at the customer's. I can't remember a time when I needed to run this particular laptop on battery. If I can use the laptop as a luggable computer, I wouldn't need to carry the weight of the cells around.

  • Has anybody tried to install Cinnamon? Does it work well on Debian ARM? I see no reason why it shouldn't, but maybe there are issues.

Well that's pretty much it. Sorry for the long post 🙂 There's precious little information about the MNT Reform out there - probably a good indication that there are precious few such machines in the wild, sadly - so I would welcome any real-world user feedback!

Hello folks. I'm wanting to learn a bit about computer hardware and firmware design, the ultimate goal will be a fully open-source hardware computer (I don't expect that any time soon). I'm familiar with PCB layout and design already as well as MCU and general programming.

Does anyone have suggestions for Off-the-Shelf CPUs that are supported well-enough by Linux and have useful documentation and datasheets available? I'm not looking for high performance, running a GUI, or anything like that. I'm literally just interested in practicing the board layout and figuring out how to extend core/libreboot to support it (out implement my own firmware) and get a terminal session.

Happy 2024! The Eco-Libre project published our 2023 Annual Report for last year.

Eco-Libre 2023 Annual Report

Eco-Libre is a volunteer-run project that designs libre hardware for sustainable communities.

Eco-Libre's mission is to research, develop, document, teach, build, and distribute open-source hardware and software that sustainably enfranchises communities' human rights.

  • Eco-Libre's mission statement

We aim to provide clear documentation to build low-cost machines, tools, and infrastructure for people all over the world who wish to live in sustainable communities with others.

Executive Summary

  • Eco-Libre was founded June 24, 2023
  • Begun searching for land in Ecuador
  • Four projects created on GitHub
  • Currently 2 active contributors
  • 2024 priority is finding land and R&D on Life-Line

Michael Altfield registered the domain-name eco-libre.org on June 24th, 2023, a few weeks after arriving to Ecuador.

Over the next 6 months, Eco-Libre committed research and designs to our GitHub org for four projects (licensed CC BY-SA) which address some of the essential requirements for a new community's basic human needs: clean water, shelter, electricity, and ecological processing of waste. By releasing these designs under a libre license, it allows for other communities to build their own infrastructure with minimal effort, and it encourages collaboration on standardized design concepts.

As Eco-Libre's projects mature, we will build experimental prototypes in our own community. To that end, Michael is currently traveling around Ecuador by bicycle in-search of land to found Eco-Libre's first physical site.

In December, Eco-Libre was joined by Jack Nugent, who has since committed contributions to the Eco-Libre Life-Line project.

The priority focus for Michael in 2024 is to determine the best region in Ecuador to buy land where Eco-Libre can physically iterate on projects.

The priority focus for Jack in 2024 is to finish the research, design, and documentation of the Eco-Libre Life-Line project.

Projects

Eco-Libre was founded this year (in 2023). In our first 6 months, we've begun work on four libre hardware projects. All of them are currently in the early research stages.

Eco-Libre Launch-Nest

The Eco-Libre Launch-Nest was our first project. The concept is to build a small-footprint, high-occupancy structure for sustainable living of 30-people.

Eco-Libre Launch-Nest 2023.09

The rooftop has sufficient space for 72 solar panels (2 meter x 1 meter) and 3 parabolic solar concentrators (16 square meter).

The structure is six-stories above-ground, which is the recommended maximum height of a confined masonry structure in an earthquake zone. It also has a basement.

The building is designed with external, enclosed, firewalled staircases on either end. These are symmetrical and designed such that the building design can be rotated around a center courtyard to have four Eco-Libre Launch-Nest structures that share the same stairwells.

Currently only basic, incomplete architectural design-work has been done in CAD. Before a structural analysis can be assessed (eg to determine the location of columns), further work needs to be done on finishing the placement of windows, doors, and dividing walls.

Eco-Libre Life-Line

The Eco-Libre Life-Line project is a series of components making up an infrastructure to deliver a clean water pipeline to a community. This includes:

Eco-Libre Life-Line 2023.12
  1. Collection of raw surface water (eg from a stream)
  2. Removal of large organic debris & sediments
  3. Removal of small particles
  4. Removal of harmful bacteria & parasites
  5. Clean water storage

Michael started the Life-Line project after visiting a number of communities who had constant issues with their water systems breaking or failing to provide clean water. The goal is to design a low-cost, self-cleaning pipeline of systems that require minimal human intervention (max routine maintenance twice per year).

This year we have half-finished the "intake" component in CAD, which consists of building a weir in a stream that funnels turbulent water onto a downward-sloped HDPE barrel with a fine-mesh screen atop it. This design exploits the energy in falling turbulent water to clean the intake screen, and it prevents the intake from being clogged by organic debris during heavy rainfall.

Special thanks to Jack Nugent, who joined Eco-Libre in 2023 and has contributed to research, design, and documentation of the Eco-Libre Life-Line project.

The goal in 2024 is to finish the "intake" component in CAD and also to design the "settling tank", "pre-filter", and "sand filter" components in CAD.

Eco-Libre Genesis-Booth

How do you sustainably begin to build a community on land without electricity and without any structures?

The Eco-Libre Genesis-Booth is a simple storage shed with >1 kW of PV solar panels on the roof. This is the first structure to be built when jumpstarting a new off-grid community. It provides the power, storage, and outdoor workshop space needed to build-out the community.

Eco-Libre Genesis-Booth 2023.06

This year we've made a simple footprint for the Genesis-Booth in CAD that's 4 meters x 2 meters -- just large enough to fit 4 solar panels (2 meters x 1 meter each). Further work is needed in CAD, but this year we also delved into making a framework for our documentation.

The Eco-Libre documentation is written in reST, generated by Sphinx, and (currently) hosted by GitHub. This is an exceptionally flexible continuous documentation solution that allows for versioned documentation matching versioned releases, works well with git, can be exported to many different flexible formats, and can be extended with custom directives written in python.

The highest priority for the Genesis-Booth is to finish this documentation as a template for other projects. Ideally this should be designed in such a way that information about Eco-Libre in general is seamlessly added to all project's documentations in a reusable way.

Eco-LIbre Treasure Tower

The Eco-Libre Treasure-Tower project is a 7 meter x 6 meter structure for storing and processing a community's waste, most importantly their food & fecal compost.

Photo of a tall 6-story structure with a wrap-around ramp and several doors on each floor
Eco-Libre Treasure-Tower 2023.07

This structure is 6-stories high and barrier-free, with a wrap-around ramp. All but the top-floor have three doors:

  1. Access door for maintenance
  2. Deposit Closet
  3. Deposit Closet

Each deposit closet contains facilities for the collection of human urine and feces and is slightly staggered in elevation so the user's deposits fall by gravity into their designated collection areas for processing.

Separately from compost, this structure also serves as a storage area for recyclable waste materials, such as metal.

This year a first-draft design of the structure has been designed in CAD, but it's very premature.

Next, a second design prototype (where the two deposit closet entrances are on the same side) should be drafted in CAD and compared to the existing design.

What do you think? Has anyone here tried out the Milk-V?

Seems like it still does have some proprietary components but hey, that's a big improvement for now.

I am referring to both the design, and the independent, and auditable manufacture of the CPU. It should be noted that such a CPU needn't fully compete with modern ARM, Intel, AMD, etc. CPUs, but it would be an incredible boon to have a fully trustworthy piece of hardware, even if it is considerably lower in it's strength. For specifics, let's say a CPU that could run a lightweight Linux distro at a "tolerable" speed.

Creating the designs for the CPU, of course while still difficult, is, most likely, the most feesbile aspect -- I presume it would "just" consist of writing the Verilog, or some other hardware description language to describe the CPU's function. The manufacture, however, is a substantial obstacle. Modern photolithography is, quite litterally, at the very forefront of human technological creation. I am just hoping that turning back the clock perhaps 20 years on the technological complexity might reduce the barrier to entry.

Here's a video of it in action: https://www.youtube.com/watch?v=iDb8_ld9gOQ

I've been using it for almost two years now, and I'm not going back.

It's based on a spare Blackberry Q10 keyboard and a custom Arduino-compatible board that reads the keyboard matrix and outputs it as USB HID to the phone. From the viewpoint of the phone, it's just a regular USB keyboard, so no special software is needed.

But I do use a custom virtual keyboard to have just two rows of symbols that are not natively on the keyboard, as I didn't want to add another layer of rarely used symbols that I'd have to memorize.

(On the image you can see Ubuntu with XFCE4 running on it. I chose Ubuntu because it's what was easiest to get running in a chroot jail on the phone. I'm using VNC to display the GUI. I even managed to get FEX (x86/x64 emulator) and Wine running, so it runs x86/x64 Linux and Windows apps.)

Btw: Is there maybe someone who wants to make a little side money? There are tons of people who say they'd buy this, but I don't want to make them.

The designs are all online and I'm happy to help. So if someone wants to make and sell them, that would be really cool! (I don't want or need any financial compensation. I'd just be happy if people have access to this.)

Hello all! My name's Evan, and I'm starting development on an idea I had a few years ago. The Synharmonium is a microcontroller-based synthesizer with control elements based on the accordion and the Suzuki Omnichord, and an algorithm to solve the centuries old musical problem of versatile just intonation. Best case, this could have a huge impact on how western music is written and performed. Worst case, its a fun and easy synthesizer you can build at home.

But right now its not much more than an idea and a janky keyboard prototype. I am a student of computer engineering, and I have a non-zero amount of programming skill, but I tend to make stupid mistakes that I can't easily spot. I need someone who's good at programming, has some spare time, and finds this idea interesting, to help me get the software side of the instrument going. If you can become a major contributor, I'd love to have you, but if you can just help me find one boneheaded mistake I will be extremely grateful, because I'm pretty stuck at the moment.

The most difficult thing about hardware to have 'libre' are the silicon chips. But times start changing. Hopefully.

The program of FSiC2023 contains diverse talks about chip design with open-source CAD tools open-source hardware (FPGA, ASIC).

I had a person ask me the other day if I knew of any stores that sell hardware with Linux preinstalled in Africa; Latin America or Russia and I couldn't think of any. I know plenty in Europe; U.S.A. and Canada but none for those places. Do any of you know of any ? They didn't mean stores that will ship there but stores that are based there.

Dasharo Update Question (docs.dasharo.com)
submitted 1 year ago by [email protected] to c/[email protected]

I recently received my MSI PRO Z690-A DDR4 motherboard from Dasharo. It came with version 1.0 which from what I understand has a different update process than later versions. Am I correct in understanding that I need to open a Terminal and type in "flashrom -p internal -w [path] --ifd -i bios" substituting the path bit there with the actual path to the file I downloaded ? Figured I would ask first before diving in.
