Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

A Framework Laptop Hacking Story
When I was getting ready to flash again, I noticed an issue about the compiler version used to build the firmware binary. I followed the advice, but more importantly I noticed that the issue has been recently fixed, and in the resolution, the maintainer says "Next release (hx20 3.19, hx30 3.07) will include them". It reminded me of something crucial: the Framework EC firmware source code repo doesn't have any particular indication of its level of stability at any given commit. Which commits could be considered fully tested releases? What if the head of the branch introduces a bug that they're working on fixing?

What is the status of offering coreboot on the framework 13?
The EC code on the normal Framework devices is already based on the Chrome EC code anyway. https://github.com/FrameworkComputer/EmbeddedController

Can I disable Intel ME / is there open source firmware?
EC firmware is open sourced by framework: https://github.com/FrameworkComputer/EmbeddedController

Framework announces AMD, new Intel gen, 16“ laptop and more
There the keyboard input is handled by the embedded controller: https://github.com/FrameworkComputer/EmbeddedController/blob...
On the 16 the keyboard is a USB keyboard that could even be used standalone, without the laptop.
- Fans not controllable?

Problem with `ectool`: `Cannot open lockfile /run/lock/cros_ec_lockCould not acquire GEC lock.`
I tried the pre-compiled `ectool` from the TamtamHero's repository as we and comiled the EmeddedController from Framework (from this repository). Both give the same error message.

The (GNU/)Linux rabbit hole has been a negative influence on my mental state
Great reminder that (as of right now) we're far removed from hardware that is 100% free (as in freedom). The closest we've got is probably provided by Raptor Computing Systems. However not everyone in the world is privileged enough to own such devices unfortunately. And I haven't dabbled into other possible mishaps that come with using such devices. The lack of "free-hardware" is a major concern though. I'd argue that there aren't enough reasons to be optimistic about this as of right now. Therefore our best bet is to not let good be the enemy of perfect; light at the end of the tunnel...

Fan Control
As far as I'm aware the only way to manually change the fan speed is using `ectool` from https://github.com/FrameworkComputer/EmbeddedController/

Framework in 2022: Year-in-review
We open sourced our Embedded Controller (EC) firmware and made it available on GitHub for you to modify if you wish.

Review: Framework's Laptop 16 is unique, laudable and flawed
There is potential for an external battery. It doesn't exist yet, but the connector supports power going from the expansion bay to the laptop[0], so someone could build a battery module or potentially even a hot-swappable adapter to use a removable battery for a more common laptop.
[0] See pins 41-51 on https://github.com/FrameworkComputer/ExpansionBay/tree/main/...

Framework Laptop 16 pre-orders are now open
We've designed the Expansion Bay module system to be able to handle power bi-directionally. One of the main reasons for this was to enable secondary batteries. This specific module isn't something we've shared any plans around, but it's something that either we or a third party would be able to build.

- Question about FW 16
-
I'm feeling unsure
According to the spec doc on their github, the gpu rail, while on AC, caps out at 10.5A @ 20V (allthoug that is the peak burst cueewnt, max sustained is not mentioned but is likely slightly lower), so we will likely eventually see some higher wattsge GPUs over time, especially give. The headroom between the 175W max burst draws we see from top end laptop chips today and a 210w limit. Thermals will liley be more of a concern than power at that point tho.(https://github.com/FrameworkComputer/ExpansionBay/blob/main/Electrical/README.md)

Framework Laptop 16 Deep Dive: 180W Power Adapter
I don't think anybody outside Framework knows for sure yet (maybe not even internally) but my impression from what they've shared so far is that the expansion bays are intended to be very easily swappable (external, a click & push kind of thing) but probably not hot-swappable while the machine is powered on.
They do have some initial specs at https://github.com/FrameworkComputer/ExpansionBay that somebody more knowledgeable than me might be able to glean some practical info from.

Framework 16 GPU connection
According to the Framework Github (https://github.com/FrameworkComputer/ExpansionBay/tree/main/Electrical) expansion bay modules (e.g. second battery or GPU) are connected via two 74-pin connectors.

Framework Laptop Cupholder Expansion Card
Framework is doing brilliant work. They create reusable computer formats that anyone can hack against. Strongly considering a Framework 13 as my next computer.

This $39 Cooler Master case turns your old Framework Laptop parts into a tiny PC
I know it's niche but it would be cool if they could attach an expanded battery pack into its expansion module.
- Thank you for Framework

framework 16 power limit? no charging port seen
Mybad, according to https://github.com/FrameworkComputer/ExpansionBay/tree/Main/Electrical ,the maximum wattage with the 'high power adapter' is 20v*10.5A which suggests 210w max for the entire device.
What are some alternatives?
