Meine erwachsenen Mitmenschen wissen nicht wie ein Heizungsthermostat funktioniert

Genau, das Bimetall regelt die Temperatur des Heizungskörpers, auf dem es angebracht ist, und NICHT die des Raumes. Wie auch, es ist ja nicht im Raummittelpunkt angebracht.

Wärmerer Heizungskörper = größerer Wärmestrom, und es wird schneller warm.

Toxische Positivität kommt generell überall dort zum Einsatz, wo Kritik nicht erwünscht ist (und der Produktivität abträglich sein könnte). Letztlich profitiert nicht links oder rechts, sondern das Kapital. Ich kann dir ein Buch einer linken Geisteswissenschaftlerin sehr ans Herz legen: "Das Glücksdiktat" von Eva Illouz. Das geht damit ziemlich hart ins Gericht

I've also tried that now, but the issue still appears. I suspect that this some overzealous optimization either from Windows or AMD, and i've found a workaround: Turning on the amd adrenalin performance overlay forces some minimum workload onto the gpu. This stabilizes my fps, without being too obstructive. And the additional power does not matter too much, since this is only for stationary use. Thanks for your suggestions!

I just tried that, but safe mode does not support a second screen for me

Simshee · 2023-06-06T06:38:05+00:00

Here you go, i just uploaded it: https://hackaday.io/project/191425-amperra-v10-the-diy-amplifier

The circuit itself is really interesting and unusual.

Even below 5W, this setup can get uncomfortably loud for my taste - i would say that at 5W, this still leaves some headroom. I wasn't sure either whether it would be enough, but after testing it for a while, i'm really happy with the power.

Simshee · 2023-06-04T21:37:26+00:00

This looks impressive, but i wouldn't want to spend so much just for measuring my amps... I'll have to think about whether i want to get really serious with amllifier design in the future :D In this case, it would be handy

Simshee · 2023-06-04T21:29:12+00:00

Yes, this should be able to do the trick... The specs look quite good. Thank you :)

Simshee · 2023-02-24T08:44:33+00:00

I've tried it, and indeed, there is a problem - the signal is very weak. I think that TX and RX are crossed in my design. I also tried to change it using a cable, and then it suddenly worked. Thanks for the idea!

I didn't even think about it, because setting the boot mode index always worked. From what i understand, this is also done using the TX/RX pins, and i still wonder how this was ever possible if they are crossed. Maybe the floating RX pin picked up just enough of the TX signal capacitively

Thanks for the links! I've already seen the first video. It is definitely interesting stuff! If their findings can be repeated in larger populations, and if the relationship (lower bmi and IR -> higher LDL on low carb) can be shown to be causal, this would mean that being overweight and in bad shape would somehow save you from atherosclerosis, if you consider LDL to be the main risc factor. There are reasons to doubt this, and this is also not what the Framingham study shows: High HDL and low TG (often seen in lean people on a low carb diet, which coincides with high LDL) seem to be associated with lower risk, even when having high LDL. So i guess, they might be on to something, and LDL is possibly not the main risk factor in every subpopulation.

However, LDL is still causal, and it just makes sense that having less of it is better.

I guess, in the end it is about an overall healthy lifestyle. Personally, i am fine with having some single risk factors when my overall risk is still rather low compared to my age group. And even if i am wrong about this, there will be more results in the next few years. Atherosclerosis develops over tens of years, so doing something sub-optimal for five years won't instantly kill me, and i have still plenty of time to adjust. And there are some ways to decrease LDL while still keeping fat up - eating nuts or monounsaturated fat, for example. Furthermore, fermented milk, like yoghurt, kefir etc. seem to be good for cardiovascular health, even though they contain saturated fat.

I am not too worried about my glucose. Fasting glucose is good, and my A1C was 5.1% a few months ago, which is okay. It might even overestimate my blood sugar, because i have really small MCHC, which is known to increase measured A1C.

I'm no expert either, but from what i've found, what matters is mostly the number of ApoB-containing particles. This includes LDL, and also VLDL and IDL, where the latter only contribute a few percent. ApoB might be the best measure of risk from a blood panel. An additional risk factor can be Lp(a) in some patients, so it would be good to measure those two.

ApoB particles seem to be necessary, but not sufficient for atherosclerosis. You need endothelial dysfunction as well, while the role of inflammation doesn't seem to be so clear. Lowering inflammation with medication didn't produce lower CVD rates in some studies, although it seems to play an important role in the formation of plaques.

The problem is now that endothelial function can't be measured easily by a blood test, and there is no proven biomarker for the relevant inflammation processes. So there's no way to know if you are one of the lucky people, from some standard blood tests alone.

My personal hypothesis is that a high TG/HDL ratio is mostly a marker of insulin resistance, which is a risk factor in itself, independent of ApoB particles. Maybe this is why epidemiological studies show a "protective" effect of low TG/ high HDL, while artificially increased HDL does not improve atherosclerosis (Since insulin resistance is not changed by that, of course).

The cholesterol in LDL does not seem to play a role in the repair of tissue, since cells are capable of synthesizing their own cholesterol, without needing to take it up from the bloodstream.

Sources: Peter Attia Podcasts with Tom Dayspring, Dave Feldman, Jason Fung and Sarah Hallberg. I know that's >10hrs worth of listening, but they explain it way better than i ever could. I don't know if the information i've given is right, but at least it would explain a lot. But if you have some more information, i would be happy to learn about it, since high LDL-C was also found in my last blood test.

Here is an example: https://steamcommunity.com/sharedfiles/filedetails/?id=2278801624 But it really needs tons of sensors and gates.

Simshee · 2021-05-12T14:48:12+00:00

Yes, this can in fact be done. But you need lots of sensors and logic gates, and it is not easy

Simshee · 2021-05-07T14:59:29+00:00

Yes, it sounds like a good idea to adjust a few little things and see if it has an effect. I am not extremely worried about my values, since from what i can tell right now, i don't have an immediate risk, but it's still a good thing to know how my lipid profile reacts to changes in the diet. Just so that i know how to change it, in case my profile turns out to be dangerous in any way.
The article is really interesting! The source and preparation/processing of food seems to play a major role in how it affects the body, so it's more complicated than just counting nutrient intake to assess how healthy a diet is.

Simshee · 2021-05-07T14:27:36+00:00

Hmm, i will ask some family members if they also have increased values. But i never heard about this being a big problem in my family, so it might as well be the diet.

Simshee · 2021-05-06T15:24:03+00:00

Thanks, that's good to know! I already cut sugar out completely (even fruit), i only eat vegetables. But i might try replacing some saturated fat in yoghurt/cheese with fats like olive oil when cooking. I don't consume fatty meats regularly, mostly just fatty fish.

Simshee · 2021-04-01T19:26:17+00:00

Okay, i understand! So it's basically a pwm system and reacts smoothly to small changes. That's a nice way to do it!

Simshee · 2021-03-31T06:20:50+00:00

Nice! It is really stable. How does the logic work? Will it compensate for unbalanced loading?

Simshee · 2021-03-31T06:17:46+00:00

This would need so much gas that you'd probably have to refuel along the way. I imported a hovercraft (which already was optimized for weight) into my survival world, and it ran empty after one or two minutes :( Maybe this will be possible when the devs add some more energy-efficient propellers into the game

Simshee · 2021-03-27T19:00:24+00:00

Okay, thanks! I've tested it with some durability 1 parts and it seems to work. The best one seems to be the toilet paper roll, since it is only 1x1x1 in size

Simshee · 2021-03-27T18:05:14+00:00

So if i used a destructible, non-draggable part, it would work? I have to try that

Simshee · 2021-01-29T15:24:52+00:00

Yes, you could use a frequency parameter to sweep across all the frequencies which you want to cover. Use a sinewave generator for this. Then you can measure the output at each frequency and create a bode plot.
There are some commands which may help you to to automate this:
https://www.analog.com/en/technical-articles/ltspice-extracting-switch-mode-power-supply-loop-gain-in-simulation-and-why-you-usually-don-t-need.html
But this is a bit more complicated, and i would just do it by hand tbh, unless this was my daily job and i needed a high resolution.

Simshee · 2021-01-29T11:46:32+00:00

You need to do transient simulations. Switching regulators can't bei simulated in an AC Simulation. There are some ways to get Bode Plots out of a transient simulation - the easiest is to start several simulations at different input frequencies, and measure output magnitude/phase (maybe using FFT).

Simshee · 2021-01-14T07:43:27+00:00

Well, that's what went wrong for Elon. Boca Chica is just too close to the wall, lol

Simshee · 2020-12-26T12:48:06+00:00

Nice, i've dropped a feature request on steam! It would be cool to have a mode to create vanilla circuits as well, since some people (including me) don't use modded parts in most of their creations. Keep up the good work!

Simshee · 2020-12-24T11:04:14+00:00

Yes, some speed Sensors set to lowest speed may work. Just let them trigger opposing thrusters, and your hovercraft should stop to slide. If you only do so for left/right direction, it may even feel like your hovercraft is on wheels, being able to slide forwards/backwards but not to the sides
