On the subject of higher dimension mathematics, I recently discovered this video : "The most beautiful formula not enough people understand" You might find it interesting too. http…

There is "MESSAGE IN A BOTTLE.txt". The first game here is to understand what the code does without a high-level README.

Thank you for sharing, I'm just starting to dig into Lua language and Love2D game engine. I will explore your game source too.

Hi Michael, [0] is a thread reproducing what I described. In that case I would like Phind's last answer to provide me with a link to the documentation or source code of 'Normalized…

Unfortunately, I don't remember them anymore and I regularly clear my browser cache. Maybe it's just the case you're describing but I'm pretty sure I was really looking for appropr…

As an occasional user, what I really liked in your previous version was that Phind always gave the list of sources. So my workflow was : - ask a question - quickly read the given a…

Hi HN! I just discovered Josh Newans' projects and tutorials about mobile robotics on ROS2. I find them particularly clear and straightforward, and I think some HN people here migh…

I don't know if it has its place here but for a minimalist static website, here is my approach: - create a simple html template using simple.css [0] - write markdown files - wrap p…

What do you mean by "better"? There are several aspects to consider. Indeed the advantage of your photovoltaic solution is versatility in the face of clouds and lower mechanical co…

> not sure where you are based in France I answered your question too quickly, I'm near Clermont-Ferrand, we have several local brewery here.

> Taking a computer out of the loop is the best way to guarantee speed and reliability. As suggested by pjc50 in another comment [0], a passive safety would be good for this applic…

Thanks for your kind and detailed reply. > it occurs to me that your system only requires an occasional movement rather than a rapid movement for tracking purposes Right, actually …

Yes I've seen a solar dish warmer with a satellite dish (manually adjusted). It was clever.

With the low-cost camera used here, the small red/green/blue pattern would be indistinguishable because the whole spot is saturated. It might be possible with an expensive camera.

Yes, this is exactly how I planned to control the temperature : add a temperature sensor in the oven and implement a simple PID in the supervisor to do so.

Nice interactive visualizations ! Yes, it might be complicated to build.

FYI, this is the "vacuum adjustable focus mirror" I mentioned: https://lm.solar/order/4-square-rigid-aluminum-composite-mir...

Nice explanation, thanks

Excellent! Do you know the mirror area used here?

Oh yes, they do. I can be a little naive sometimes :-) I still naively think that we could make mirrors completely encased in glass to limit their degradation (pure speculation her…

> I like your cable-drive concept by the way. Did you describe it in more details anywhere? I didn't take the time to describe the cable-bot concept in detail. I modeled almost all…

Very interesting, do you know if there are any actual applications today?

I wasn't aware of such systems. If I understand correctly, their main feature is that they do not focus on a focal point, but instead diffuse the light. So I'm not sure if it would…

I think it depends on the mirror area. The more mirrors, the more power. The more power, the higher the temperature will be. Anyway, tungsten melts at 3422°C, I don't know if it's …
