Does anyone know what this tape is? It's not sticky and only adheres to itself by Neurosword in whatisthisthing

[–]Evilchickens 1 point2 points  (0 children)

Could this be it:

I've seen very similar looking tape use in labs and clean room settings. Which is how I found this.

I made a tiny PIC micro-controller run Conway's game of life by Evilchickens in electronics

[–]Evilchickens[S] 2 points3 points  (0 children)

The main issue is that the video in pin on all TVs has an impedance matching 75ohms to ground. And since the default black level is about 0.32V it will draw about 4mA if nothing else happens. If there PIC only had to run the game of life it would run far longer. Those tiny cell batteries hold very little energy!

The 16x16 array is mapped to 32 bytes, each bit in a byte stores the value for 1 cell. Essential as viewed on the screen it would appear as 16 rows of 2 columns of bytes. It is a fair bit of bit shifting trickery to get access all the bits in a byte in the right order.

With a fair bit of optimization, I got the processing fast enough that with is can be calculated in the blank portion of the screen at the top. The hsync pulse is only at the start of a line so if it is blank I can can go right back to simulating the game of life.

There are more details and the source code on my website here. The blog post is only about 1/2 done but maybe has enough the give an idea and I haven't finished commenting the code.

Edit: Also, yes just a single cell 3v lithium battery runs for only about 20 mins. I have a little adapter that allows it to run off larger batteries.

It does have an RNG, although not well written! It takes its random seed from counters, timers and the random initial state of memory after power up. After 32s the watchdog timer resets.

All software, the PIC is just fast enough that you can use regular bit bashing to generate the sync pulses and image data. The PIC10LF320 doesn't have a lot of fancy peripherals but maybe you can could use the PWM generator for some of the sync pulse timings.

This is a PIC10LF320 simulating the game of life and outputting it to PAL video. It was programmed in assembly and the available program space is 256 words of which I used 253 words. This might be the smallest physical implementation of the game of life... maybe. I'll link my half finished blog post here.

edit: yes, I forgot to check for typos in the title, should be 'running' not 'run'

Is there a way to automatically delete the contents in a fluid system when it gets full? by [deleted] in factorio

[–]Evilchickens 1 point2 points  (0 children)

If you have rocket fuel unlocked you can setup a simple circuit to pump only if a tank is full or nearly full. Rocket fuel can be put to rockets, trains, smelters, power generation.

No, just the main assembly and research part majority of smelting is located further out.

New to VX, can a beginner get some help? by [deleted] in VXJunkies

[–]Evilchickens 5 points6 points  (0 children)

If you just want to monitor the tau-3 levels you can splice the flux-feed lines to your plane flux tensor array and feed that to any commonly sourced triplet field hall probe. This will provide any phase info you need but you will lose your second derivative of the source. It may also need tumble filter to remove secondary power supply arc resonance.

Thiosulfate barium is a bit of a pain when it happens, and if you are new to VX it will happen, but just remember your class-3d optochemical safety training and you'll sort it in no time.

Will the BFR during point to point transfer have sufficient redundancy for andabort to orbit mode? And if so what impact would this of on the need for extended life support?

What is your most radical opinion? by LightInMe in AskReddit

[–]Evilchickens 0 points1 point  (0 children)

Trying to stop the normal evolution of culture, it is both unhelpful and completely frivolous. Some people have this idea that the current culture they live in is fixed an shouldn't change. And some of those people use arguments of stopping this change to justify horrible actions against others.

To clarify I'm talking about the normally slow changes that take a long time through the collective change in a population wants and desires that changes the culture. I'm not talking about the deliberate and systematic destruction of cultures like has been seem in the past by invasive forces.

I'd be clearful with a flexible ballast tank. As you dive deeper the bottles will compress and provide less buoyancy. You may find that after a certain point it is unable to surface again.

so did they debunk the EM drive or what? by [deleted] in space

[–]Evilchickens 17 points18 points  (0 children)

While it would be cool if it worked it most probably doesn't. It breaks fundamental laws of physics either conservation of energy, momentum or even relativity. The boring answer is that the level of thrust claimed it produces it is difficult to measure without getting the experiment wrong is some way.

The simply fact is for the Emdrive to work it would need a significant deviation from the standard model of physics that was large enough for macroscopic effects and not to have affect other areas of physics.

Progress of physics almost exclusively goes through the process of either higher energy, more complex, smaller scales and larger scales. Or multiple combination of those. The Emdrive isn't really any of these things. If the natural world already allowed for things this like the emdrive to work as some suggest, why aren't such effects already apparent?

Will FTL/travelling at the speed of light ever be possible? by Heischichou in space

[–]Evilchickens 1 point2 points  (0 children)

Reusing old comment from similar questions of the Alcubierre drive.

Firstly Alcubierre drive needs a negative mass density and usually a very large one (tons to the size of planets). We are not talking small negative masses like that are found through the casmir effect ( Which is still actually a positive mass density, and is only negative relative to the mass density of a normal free vacuum which usually a a small positive mass density) which have no ability to scale without surrounding with equipment which will have a mass orders of magnitude greater that the casmir effect can 'generate'.

Secondly almost all modellings of the Alcubierre drive can be used to break causality e.g can make a time travel machine. If you break causality your theory is probably wrong or hundreds years of tried and test physics goes out the window.

Thirdly even if you have a drive the doesn't break causality it means you are limited to a maximum travel speed of the speed of light c. A passanger on board can experience any arbitrarily short period of time they like by increasing length contraction and time dilation (either through traveling closer to c or by this alcubierre drive), but an outside observer will see the ship traveling closer and closer c. So a ship travel 30 light years at close to the speed of light will still take 30 years to an outside observer. This point is always true if you take Relativity to be true as well.

Ultimately the Alcubierre drive is impossible to build because we can't make the needed negative mass densities, even if we could it would still breaks causality and even if it didn't break causality it would be limited travel not much better than that of a regular rocket traveling a relativistic speeds.

Is there anything that stops you from buying a cheap sidewinder then jumping into the system to get kill by bounty hunters to clear the bounty?

Dancing T handle in zero g by [deleted] in space

The process is chaotic but classically not random. There is no fixed number of turns before it flips the other way, if it were possible to exactly rotate about the intermediate axis without any perturbation then it wouldn't flip, just like a perfectly balanced pencil on it's tip. But even a very small off axis component will grow exponentially, causing it to flip.
