My DIY power supply

Now I can check small devices such as LEDs, relays and something!

I'm so proud of myself because it is works and nothing exploded!

Features: variable output voltage(0 to 15V) with graphical display. Used old laptop power supply(19V 2.3A).

P.S. schematic on the last photo

Custom Engraving

Has anyone tried the custom engraving? How does it work, do we hand in a .svg file?

What are the maximum sizes that can be engraved? Minimum line width?

Thanks :)

The worst case scenario for climate change has been deemed implausible due to the falling costs of renewables and emerging climate policies

This is not an outright super-optimistic paper, but at least we managed to upgrade our future from a guaranteed catastrophe to a monumental, winnable fight. We are no longer flying blindly toward the worst-case scenario, but our current level of effort (the Medium path) still drops us directly into a high-risk zone for cascading ecosystem failures.

To achieve true stability, we have to aggressively transition from our current path to the "Low" or "Very Low" scenarios outlined in the framework, which requires hitting net-zero emissions rapidly over the coming decades. And we have to avoid the global fragmentation where too many countries drift towards nationalistic goals.

On a personal note, as someone who has lived for over half a century on this only planet we are blessed with, the fact that clean energy is now mostly cheaper than fossil, the fact that clean energy makes also sense from a geo-political point of view, and the fact that many of you younger ones no longer see cars as a status symbol all fill me with hope that humankind might just manage and that the current swing toward anti-science, anti-green, anti-evidence, pro-billionaire is just a (final?) swing of the pendulum before we return to progress, hope, global collaboration and optimism.

Switzerland has "statistically significant declining cases of academic freedom over the past ten years", this follows a worldwide trend.
