Was it possible to build it for $60 when you built it though?

As for the idle dray, a lot of PC's have Wake On Lan so you can power it on via a special IP packet. I could't get it to work on mine, so i pus an esp32 based power monitoring plug in front of it, and configured the PC to power on directly when powered. When the power monitoring sees the PC sleeping for some time, it cuts the power. I control the plug via home assistant, so i can switch it on remotely


No. I bought it for about 150 shipping included from Canada to Spain. I reckon I spent about 300$ in total, the most expensive thing being the 1Tb NVMe.

I don't have an ethernet cable where the box is, so WoL is not an option for me either. I could have used something similar to your approach (very smart, by the way!) but decided to go ESP aiming for the most console-like experience of just grabbing the controller and playing your game


WoWLAN is a thing. On my motherboard it works so well that it wakes up whenever my phone, laptop or steam deck connect to the WiFi, not just when I actually send the magic packets!


First time I hear about WoWLAN, thanks! I will check if it can work with my cheap usb Wifi adapter.

Yours seems a bit too eager though! I wouldn't want the thing to start up every time I get home as it turns the projector on, which lowers the projector screen, which blocks the (small) apartment's main entrance when lowered and would make me enter home on my fours ¯\_(ツ)_/¯


Yeah it's not actually intentional; I have sunk a lot of time into trying to stop it happening. The firmware on my motherboard sucks; I couldn't even suspend it before the last bios update. Relatively new board.

On the other hand if you re-arranged the room, it'd be neat to walk in to everything deploying!

Would you mind to share here or by DM where you ordered items from? I’m in Spain and would like to build something similar.

Thanks


Hello fellow Spaniard! I just checked the prices and they don't make any sense anymore. A few weeks back you could find the board in Aliexpress for 150eur, now it's twice that price or even more. I got mine fom eBay, didn't think of checking Aliexpress at the time. As per the other parts, I got a quite fancy Metalfish PSU [0] (was on sale when I got it), a power button [1] from Ali (not necessarily needed) and an ESP32 [2] for the remote power on. Then a high pressure fan, I went with Arctic P12 Pro [3]. Wifi and BT adapters whatever works on Linux will work.

Ouch! Thank you for checking it! It’s always nice to find Spanish people here :D


Yep, everything is lacking. No version control, ladder diagrams instead of written code, goto statements as primary control flow in code. A $500 PLC with less processing power than a 1985 086 and 1 whole MB of memory. Upgradable with a $200 license to 1.5MB, only programmable with a 20GB monstrosity of a piece of software in which download means copying a program.e to the PLC, and upload means downloading a backup to your laptop. That world needs some disruption really really bad


Hey, hey, a little trigger warning over here? My last job before retirement was in that world. If it had been my first software job, it would have been my last.


Nice, but not sure I agree with your use of voxels. It appears more like pixelated height map, not the use of 3d pixels. From what I see every position on the globe can only have a single elevation


Each pixel is a cube drawn at a certain height based on the terrain height map data. It’s not a volumetric render, I agree.


Best would be to capture CO2, and then solidify the carbon to a compact stable stable state by taking away the oxygen. Then we have a highly concentrated pure carbon form that we can just bury underground. Or add some hydrogen and get this liquid state that we can pump back into those empty underground reservoirs. But maybe we should stop taking it out in the first place...


We get energy by extracting oil and burning it. It takes a lot more energy to do the reverse.

We already cannot stop burning oil today because the economy would implode. I don't think that it is reasonable to think that not only we could stop burning oil entirely, AND at the same time produce more energy than we got from oil just for extracting the CO2 from the atmosphere... And the reality is even worse than that, because on top of all that* we would need more energy to... live.

It's important people understand that we cannot extract the CO2 once it's out there. It's practically impossible, period.


You are talking about trees...


Trees that disappear in huge fires more and more often, unfortunately.


One of the many reinforcing feedbacks that contribute to making global warming such a difficult problem.


Reminds of Digital Logic Sim by Sebastian Lague, which I really like as you start with just a NAND gate and go from there.

To me (EU) that seems like a pretty generous limit. A normal house connection here is limited to 8kW single phase or 17kW for a 3 phase connection. You can get more, but that is very uncommon and gets expensive quickly


What is seen, cannot be unseen


I wonder if and how you can use this for steganography, hiding data in plain sight. I bet most automated image analysis programs would only consider the final image. I sure some highschooler can use this to bypass their schools contentfilter


Yep this is an AI subversion technique for sure. Put the message to the humans in the first frame, and the message to the AI in the final frame.

This is how we defeat skynet: by sending each other pictures of cats.


You could probably implement a server that is purposefully slow enough so that the human frame shows up for however long you want. Just need to send the keepalive bytes one-by one.


I can't see any way this would beat regular steganography.


I ported a decades-old piece of scientific software (Delft3D — Deltares' Fortran hydrodynamics engine) to run natively on Apple Silicon. From my phone, mostly, because I could (and because AI could). Runs pretty decently on a Mac Studio M3 now.

It was officially Intel-compiler + Windows/Linux only; the port gets it building with gfortran on macOS/arm64, PETSc+MPI solver and all. Fable and GPT-5.6 chewed through the compiler warnings, dependency hell, and portability bugs largely on their own. 30 or so bugs uncovered and fixed along the way, several of them real and platform-independent.

I'm not a C or Fortran dev. Mostly I argued with the agents about benchmarking methodology and told them to re-measure when the numbers looked off. The rest was up to them. Still amazed about this AI thing going on

What do you plan to do next with it?


what's your workflow for doing the port?


I installed Claude Code on the Mac Studio, and gave it access over ssh to a Linux box. I instructed Claude to first compile on Linux, create reference artefacts, and only then start the work on mac. And then to make sure the Linux version still would compile with the changes made to the compiler toolchain, the Mac specific instructions etc.

I told Fable to make a nice plan, and fan out work to opus and sonnet agents. I then enabled remote connections and checked every few hours from my phone and nudged it in the right directions where needed. Have some push back once in a while. And once done I asked it to make a nice commit history and remove all the dead ends.


Nice use of civic tech! Have you ever showed this to open state foundation? https://openstate.eu/
