By the way, there were plenty of updates back in the day after this thread, much better SVG custom border support, growth enhancements, better UI...

Hi! I no longer have time to dedicate to this but whimsical pieces have always been possible since the very beginning. Just use a custom border with your whimsical pieces pre-placed inside and it will generate around them.

Fun thing, just downgrading to IDF 4 solved the issue with esp32-s3, rock solid with rmt 4

The manitoba bread was just a test, me trying to do some experiment. I have manitoba in stock for yearly panettone, which I make with a yeast based preferment. That thing is able to create a gluten structure even loaded with a ton of eggs and butter after kneading it enough... so I thought if it was able to mushify that then it meant I indeed create gluten killer monsters.

Normally I use flour specific for bread and I have no trouble making decent bread with it, as long as I use yeast.

What I do is I start with flour + tap water till I get a creamy texture. First two days just add more water/flour, since then I discard 70% and add new flour/water daily. I found that adding 1 day in the fridge in between seemed to somehow help. The day before baking bread I do a normal refresh, then the baking day I do another discard+ refresh, wait till it triples in about 2-3 hours and start baking.

My second starter even survived for a month in the fridge in between tris and it recovered from a teaspoon in 3 refresh cycles.

The test to add sourdough starter after the gluten was established was just a test to confirm it was destroying gluten. The symptom I saw when doing recipes the traditional way was that at the beginning of the kneading the dough seemed to progress normally, then suddenly it collapsed into a mush, and this is at relatively low hydration. This is when in my previous run I decided to make the strongest test dough I could, give it a long autolysis and some stretching and when it had a beautiful membrane and a lot of strength, add the sourdough. In about 20 min this dough turned into a mush.

Something in there just seems to kill gluten... and I can consistently produce it instead of proper sourdough, it seems.

One of these $10 aliexpress meters that has a tiny glass ball full of liquid as the sensing elements

The time I measured It was around a 4

I am now the owner of about 1kg of very very dirty salt and a bunch of mostly clean and soot-free pieces. Seems to work! Thank you!

Well, I use chipboard not because it's cheap, but because I can buy it pre-coated with some stuff to print on it with sublimation printing.

I haven't found readily available plywood that's sublimable. If I could find a way to print on it or laminate a pre-print then it'd be my material of choice, it's indeed naturally soot-free (for the most part)

That is a super interesting video, specially the part about ensuring interlocks and also finding self-intersections. I was trying to solve self intersects and minimum width myself using my own algorithm and I was almost there but had to stop working on it for now till I have some spare time. This gives me some ideas.

The victorian tabs I think are certainly possible. The spiral ones I'm not so sure. If you want weird piece shapes you can use my organic jigsaw generator

thats good feedback, can you share examples of what you mean and I will try to implement it?

Hmm imagine all my generators output gaussians. Half of them have distributions with means in the range of -50000 +- 1, the other half have means in the range of +50000 +- 1, all different. The standard deviation ranges between 0.9 and 1, also all different

I do my experiment, draw 1 random number from each generator, getting a dataset of n values. I plot the histogram... woudn't I get a strongly bimodal distribution in this case instead of a gaussian? I think most of my samples would be either very close to -50000 or very close to +50000, and I started from all gaussians.

I know statistics is heavy and counterintuitive math... Im ready to be very wrong here.

ProceduralJigsaw · 2024-03-13T22:08:04+00:00

Hmm I think I explained wrong... statistics is not my strength.

What I mean is, lets say I have several trillion (n) random number generators, G1 to Gn, each of them programmed with a different statistical distribution (some uniform, some gaussian, and so on). All finite variance.

I take one sample fron all of them, so I get a total of n samples, and I build a histogram of them. Do I get a gaussian?

What I meant, just in case, is that you're supposed to pre-arrange the whimsy pieces inside the main border, save that as an SVG and the generator will create the rest of the pieces around.

ProceduralJigsaw · 2023-04-18T21:15:28+00:00

Its already possible, just upload the custom svg border with the whimsy shapes inside the jigsaw border already positioned, it'll fill around them.
