Annon how do you think the sounds that were created with the help of mathematical formulas affect a person ?

The "rules" in art are more like guidelines to create "generically appealing" works of art, the best artists bend and break these rules to create the unexpected. Adhering to them staunchly will just net you a boring, but pretty, work.

Yes and no. I'm thinking in a broader sense.

The rules aren't a template for creating appealing art but they do include how that works, but also how to break that and what happens when you do. Dissonance in music for example. A lot of bending and breaking of the "rules" that you are thinking of is actually described by maths and science and the toolbox I'm thinking of.

You are right that artists do bend and break the confines of this automatically appealing guideline and yes something they break new ground entirely. But a lot of the time they're still doing what those rules would indicate, just doing something different with them.

I have come up with a method. I just lack the technical know how.
You would need basic laser technology, but modified so that the laser gas is generated from the surrounding air with an oxygen concentrator. If you could manage to push enough energy through it, you could have a cutting laser. Now, there are ways to magnify the laser into more of a blade, but the issue is a laser just goes on and on, it doesnt stop. So you would need a way to stop it. I suggest a telescoping heat resistant pole that extends when activated, at the end of which is a circular beam trap. Instead of one laser, this design would call for a circle of beams around the inner pole which would make a wider blade. The inner pole could also likely be used to block. The lasers would only be for heat.

Cant be used for stabbing
is like a first gen prototype and not so combat worthy
im not sure a metal strong enough exists
im not sure enough power could be made portable unless a mini generator was invented

would absolutely cut and burn,
would definitely resemble a lightsaber.
is absolutely possible

add ideas or use this stuff guys, lets become jedi

>circle of beams
None of these is a lightsaber. Why the fuck does A Wizard have to come to /stem/ to fix this shit for you?
PLASMA! A lightsaber should be PLASMA!
>but why
Because a plasma will work properly and allow you to go through steel with it and not have to worry about loss from reflective surfaces and all that other shit... but more importantly, a plasma can be held in form by a magnetic field. Now, by using a plasma instead of a simple laser, the only question is by what means you will be generating and shaping this magnetic field, to hold and sustain the plasma while you flail it around at things.
So, you don't need a pole, you don't need anything on the other end, you just need to generate the field in the appropriate shape and with some serious strength... hmm, well I answered the question.

how do i realistically preserve my brain past the death of my body? must i keep blood supplied to it , harvesting more and more fresh blood, or may i simply have new organs connected to my system every few decades? obviously i will need to be fed and cared for which presents its own problems. i will most likely lose motility, unless i am some how gifted advanced robotics, even then it is unlikely i will ever again come close to the perfection of the human form. it is more likely that I will gain additional appendages such as arms and eyes that should be able to take in information, and output. access to the worlds' life center : the internet. research into xeno-transplantation and overcoming graft vs, host disease is highly suggested for study . s t i r k

I think the video is supposed to be pretty self explanatory.
From what I've seen he is starting with a ray from the origin (0,0) and 0° degrees. Then measure the distance to the first edge of the madelbrot set that the ray intersects. The magnitude of the resulting vector is then used as the first sample of the audio.
Then increase the angle of the ray, and repeat the process.

This is an interesting idea. you could even modify the sound if you pick different origins for the rays instead of 0,0 (should work as long as it is within the set)
or alternately use the same process with different Julia sets.

All in all neat idea!
I would find it quite interesting if this could be turned into an algorithm suitable for real time sound synthesis in a VSTI and such.

Frankenstein needs a motor

That produces as much or more torque and has at least as much dynamic control as an 120 AV personal massager for female masturbation. The idea isn't actually to target the clitoris specifically as other grinders have discovered as the entire penis and forward pelvis can serve as a vibrator if done properly.

The problem is the intensity, I want to achieve the same amount of penetrating vibratory force as the machine, but since the volume of the surface that is vibrating is different, depending on the motor position a precise copy of the other motor may not be the right choice.

Essentially, you just have to make sure you can still get erect. According to another grinder who did this, it's actually quite pleasurable for the dude to turn it on as well as the woman.

The issue is putting any kind of 120v circuit in an implant is pretty much absurd but I want to test the limits of what can be. The motor is a "The motor SN3658–220-GHSF is a 6600 RPM, high voltage brush motor made by Igarashi Motors USA." I think the motor voltage is actually a bit higher like 170v.

So.. we have a willing guinea pig, and I know of a piercer who will put inside me, and I know I'll need medical grade bioinert titanium as well as sterile silicone. The other big problem is where to put the battery, but it can actually be located elsewhere as long as a wire can be run to it, but that also seems annoying.

I'm going to try to run up some basic ratios on motor torque vs battery life vs the kind of inductive charging PCB stuff you can get off shelf. The easiest part is the remote, which can probably just be made using an android integration kit for DIY electronics from amazon.

Thist is the second dick fatality on 420chan this year. Remember there was the dude with the dickbox on /b/? His dick got stomped on, then infected and now he's dead. Then there's this vibro dick dude. he's clearly dead.

That's wild. Two dick deaths in like 3 months.

So far, humanity's all time high score for living is 122 years and 164 days.
That's using the old fashion technique of health, wealth and happiness.

What I want to know is, if we cheated nature a bit with current or future technology, how long could we live?

Wtf my diet consists of home cooked meals made with organic and grass fed ingredients and all that shit, either grown in the garden or bought from local co-ops. I also walk daily. Plus i'm not an alcoholic, I don't even drink much really.

Unfortunately i'll actually probably die super ugly due to mouth cancer from non-stop cigar and pipe smoking. Shame it can't be prevented.

Will this actually work?


Phenylethylamine (PEA) to Amphetamine :) PURE

  1. Add an OH group. Dissolve your PEA in warm ethanol (alcohol). Grain would work, i use hand sanitizer (after salted out of course). No boil off that ethanol on about 180F. Can go up to almost 300F if you want to speed it up.

2. Scrape the remaining white powder off the pan. Place in a mix of white vinegar and warm ethanol. Let it dissolve. Now boil this shit off on same temp. Now you have a Ketone aka ====O. Next you're going to methylate this and have Amphetamine.

3. Scrape this powder off pan, place in a VERY small mixture of methanol and acetone (1mL per gram). Shake it. It should react ithin 2 minutes. Now filter this and let it dry. You just fucking made pure Amphetamine. Go give some to your friends. Take some too. Keep a big stash. Sell a bit even.

I would take your PEA, throw in a base and some methyl chloride and pray to god things work.
Jim - Wed, 11 Sep 2019 04:58:03 EST swebEcb2 No.79581 Reply
PEA has strong base properties so the OH as a solvent to completely disolve the PEA would very possibly yield an acetylated PEA and if i am not mistaken asprin also works to acetylate compounds(DEA Microgram) and and im pretty sure a methyl group can replace an acetyl group the acetone methonol keeps the PEA(post acetylation) from becomming solute.... i think this simple reacton would make alpha-methy; phenylethylamine acetate, maybe react with a tiny bit of muritac to yeild the HCL

Explain it to me a lay person.
The issue is they don't have enough energy to:
A) Create and sustain a reaction long enough
B) Also power the containment of the whole reaction at the same time
C) Generate this whole reaction not at some massive net loss of energy.

Maybe I'm stupid or over simplifying this. Why not hook one of these big fancy Chinese reactors directly to say a gigantic hydroelectric dam (or other renewable resources) that more or less generates infinite huge amounts of energy and use those to power reactors?

Pretty stoned.

Regarding a "hydro" power "battery"
It's feasible to think about a torridal container in which a superfluid slushes around friction-less. If the walls of the container are strong enough the momentum, or speed of the superfluid could be increased by arbitrary amounts.

Where it breaks down is of course we know of no superfluid that remains stable without constant cooling and no materials to build the container out of.
Furthermore every conceivable method of extracting or putting in energy from/into the fluid will have losses.
But I suppose if we can use superconductors all over the process those losses would just amount to imperfections and quantum fluctuations.

The question in OP while interesting doesn't make sense to me without some creative interpretations.
Also congrats OP of being able to continue your stoned train of thought at a later date, I'm jealous.
