Hybrid Power Systems! | Real Life Power Armor (Part 4/6)

[@ChuckUFarley90]

SWITCH THE GASOLINE OVER TO PROPANE! The energy density will be slightly less, but it burns cleaner, which is IMPORTANT in confined spaces without good ventilation. Plus, Propane doesn't care what orientation it's in, so it can keep going even if the suit falls over. Also, small Propane bottles are cheap and easy to swap out like a fusion core. And propane won't decay like gasoline will, so barring any leaks, it'll last forever. TL:DR, Propane is a straight-up upgrade.

[@duckfoo]

What's the energy density difference and volatility between the two?

[@yakirfrankoveig8094]

​@@duckfoo quick google search says 34 MJ per liter with gasoline vs 25 for propane it terms of density per kg its slightly higher for propane so for the same amount of time the gas is lighter but the tanks are heavier so the practical ratio will be bigger than 2/3 Maybe its worth a consideration but i have no clue how propane compares to gasoline in terms of bhp and torque outputs per liter displacement and varriying amounts of cillinders. adding a turbo would be cool though more efficiant and you'd get the engine screaming and that turbo spoolling up chefs kiss

[@markfergerson2145]

I liked the power density lecture, you covered the high points without getting too deep into the weeds. On the other hand your explanation of the power pack design glossed over several rabbit holes like heat management. Which components physically fit where doesn’t take into account their thermal environment, stuff like that, but I get that there are a half dozen similar rabbit holes like vibration and airflow management there at least. I suspect that you only got into the depths that you did because a large part of your audience can see things like that without you having to hold our hands. Thanks for the respect, people.

[@conneryates5073]

Yeah I do worry about overheating and cooling management especially for the electronics the engine and the user. Because I know the engine produces a lot of heat and it’s next to a lot of electrics. So they have to keep the electrics and engine cool if not there very well could be an explosion on ones back.

[@edward9674]

@@conneryates5073 Agreed. Heat management is not something everyone thinks about but it is very important if you want to use something for practical periods of time.

[@PlasmaChannel]

The augmented and complimented movement / strength you got going here is remarkable. Definitely the right direction guys! The fact that the compressor fires up during use to maintain pressure....that's real world functionality. Gas is the right choice too - energy density is king here, plus that menacing noise is prime. So when do I get to hop in the suit :P

[@BlacKi-nd4uy]

is it? i think, energy density isnt that much important if you dont wanna use it unpowered. much more important is power to size ratio. therefore i wouldnt go pneumatic but hydraulic. its also more precise. pneumatic is easier to work with, but in the end, it has way to much disadvantages. but its ok for a prototype i gues.

@@BlacKi-nd4uy I would like to see a hydraulic version of this, you could replace the hybrid pneumatic system with a larger engine It could be way stronger too, probably even strong enough to negate the added weight of the hydraulics Of course, the main problem with hydraulics is speed and not being able to allow unpowered movement, unlike their pneumatic design

[@BlacKi-nd4uy]

@ i dont think hydraulics have real negative sideeffects when operating. unpowered movement still would be possible if its part of the design, but i also dont thinks its necessary. hydraulics only may more dangerous for the operator and the enviroment, since compressed gases arent a problem at all. it think thats why they do it pneumatic. its ok for a prototype.

The fact that you guys are able to do stuff like this is inspiring. My only advice with the hybrid system in finding a less dangerous fuel source when you are in a enclosed space or at least make sure that the engine has proper exhausting to make it quieter and to keep the fumes from disorienting whoever is in the suit. but you could always make a air system to the helmet which would be sick.

[@sintanan469]

​@@hacksmith Most concern I have is the exhaust fumes from gasoline are filthy. The CO can be dangerous if the motor kicks in too much in an enclosed space, but likely it will just be more of an annoyance to other people around if they're stuck smelling the exhaust at, say, a convention. Otherwise as long as you guys have decent ventilation in your workshop, and with how planned out this project is I have to assume you do because you seem to dot all your T's and cross all your I's, everything should be fine. As for the decibels... I don't really have any suggestions that wouldnt be excessively bulky, save maybe lining the outer shell of the back with foam to try to absorb some of the sound.

I am not entirely sure how and what sort, or exactly for what, but you definitely need pressure sensor in the sole of each boot. Best guess at the moment is to tell the suit what fraction of total system/user weight is on each foot, and use that input to help tell the leg augmentation system what it needs to be doing.

[@mosiahbennion706]

Watch the interview The Hacksmith does with Jon Youshaei, they talk about how it costs so much to keep the channel afloat because it’s basically a manufacturing company that doesn’t create consistent products. Because there’s such a financial noose around them to keep the “factory” running, they’re forced to do the sponsors and easy projects that they know will bring revenue otherwise they’d have to close up shop.

Yeah, I was kinda wanting to have the guys try harder to impress upon the viewers what this sort of backpack-mountable hybrid power system represents.

A couple more years spent refining the control systems, and you're talking about a suit that provide useful support for jobs like logging and ranching. I feel like everyone's underreacting.

[@Azeryn_Sylver]

I believe that the limbs are hydraulic, but the suit itself is pneumatic. Especially since the suits are supposed to be air-tight to allow for combat in radiated environments and potentially even space. So when the suit opens and closes, those pneumatic noises would be the suit depressurising and repressurising.

[@leosmith1522]

Hi Guy, Love the work, I've worked in animatronics for the last 30 years. When we have built pneumatic robots in the past, we used a system where you put pressure to both sides of the cylinders, through pressure regulators. This allows you to to trim the forces on both sides of the cylinders and allows you to make the robot float in a neutral position. (Like air springs). When you want to curl the arm up. By letting the air out of one side of the cylinder the other side pressure pushed it the other way. You use flow regulators on the exhaust to control the speed of movement. Our robot is used to freak people out, because when they're standing still, you can touch, push and pull them. And they really feel life like. Though when you cut the air supply they flop into a heap on the floor. Just like sleepy people. If I was building a power suit I would use this system. As the weight of the Armor is neutralized. With our most advanced model, there was sensor feedback from all the cylinders( Pressure v Gravity) and the computer automatically adjusted the pressure depending on the body's position. This stopped flailing about when the body position changed. (say when up becomes down the pressure has to be reversed to keep the loads in equilibrium. Keep up the cool projects.

[@TheKingsRook]

18:20 Not sure if its something you're already bearing in mind, but you also have to consider how range of motion might change the detection. You're (correctly) identifying that if you were to hold your arm out, the pressure on the upper cuff is naturally higher because you're holding your arm up, but you can't just zero it at that point and then set the pressure differential before actuating, because then when your arm is hanging down at rest you will need to apply significantly more pressure on the upper cuff to bend the arm. The programming should take into account that the pressure differential between the upper and lower cuffs before actuating will need to increase as the arm angle approches perpendicular.

I’ve been getting into engineering and I’ve been noticing the absurd prices and was curious about the price of some of your projects, also you guys are very skilled and smart.

[@UKBUILT]

There projects will be 5-100k in parts, but you need alot of tools to even start something like this. This is probably one of their cheeper projects to replicate, You can build something like this yourself for cheep that does the same job. Used Pneumatics are actually quite cheep. I love how they are going the extra mile tho to make it all look nice and function well 😎👍

[@rat-r1f]

The solution you made to rid the armor of all the buttons was ingenious! you know what they say in Murphys laws of combat: "When two armies collide, the one with the simpler uniform wins"

[@Starfighter-nk4mo]

Controlling the armor with your body movements is a really important point. This is how the first ever sci-fi depicting power armor, Star Ship Troopers, (1959) wrote about it, and how it presumably works in almost every setting it exists in. You push on the armor, and it moves with you like it’s not there at all.

@@Starfighter-nk4mo space marine power armour in warhammer 40k is controlled by a direct connection to the wearer's brain, but I don't think we've got the technology to make that viable yet

RTG power source upgrade coming soon

[@crazynachos4230]

I feel like theres some really cool potential there to turn the generator onto an actual war cry, like James said it would be INSANELY intimidating

[@artor9175]

"Oh crap! It's powering up! Take cover!"

[@yeetmcmeat]

it kinda sounded like a war horn or a siren to me, Imagine being the poor dude cornered by raiders and a deafening horn blast echoes through the alleys you're hunkered down in.

[@theoriginalbeanboy]

while it doesnt run off of a fission or fusion generator, you can plug a toaster into it which is dope

[@MaverickHenderson-u5n]

You know that makes it even better than in game

[@Yeetely_deet]

Gas toasted bread sound fricking delicious

[@John_Conner222]

WOW this is impressive. Bravo man this is some great work. I think with some tweaks you could bring down the decibel levels significantly and I believe someone else suggested switching to propane.

[@Sci_fi_and_cars]

With the generator making that much noise you might think of adding a muffler from says a tiller or go cart? You young people have to protect your ears. Love the build btw 💜

This just shows how incredible our bodies are. We can do all of that with just some food and water, and it's super compact!

Sarah is getting more comfortable in front of the camera, and I'm starting to really enjoy seeing her on projects! How long until we get a Sarah run project? Keep up all the ridiculously good vids!

[@hacksmith]

Sarah is new... This is her first video

[@RevvyTeva]

​@@hacksmith Now I feel bad! I'm so sorry, I was sure I'd seen her in the background of a few previous videos, but I could just be really genuinely faceblind... I apologize to you guys and to her for getting so mixed up! Regardless, I love her energy on camera, and I hope she's involved in more projects!

[@karolniedbao5420]

0:27 lol when did the TV series become the source material?

[@CouncilOfRem]

Since…it’s canon?

[@augustofilosi4706]

Well, according to Todd Howard the series is also canon

[@BenMurgi]

In other cannon material (in my opinion more prevalent) when a suits fusion core runs out the individual wearing the suit is still able to move and exit the suit, just at a slower rate and assumedly the cost of greater endurance.

[@afairlyradlad3933]

Amazing upgrade here. The full suit is gonna be absolutely wild and the bulletproof armor is the cherry on top. I think it would be absolutely sick to experiment with the armor in critical areas like the torso and maybe should pauldrons by using Crash Makerspace's 3d steel lattice armor design. Its fairly light weight, can be molded to whatever geography and can stop 308 rounds. That combined with the nanovate coating would be unstoppable.

[@Goofy_BASSTURD]

This is some genius work. I’m surprised no company has done what you’re doing. I have a feeling this isn’t going to stop at power armor. You strap some rockets to this and it’s iron man mk1. Landing probably won’t be survivable. But it was a movie.

[@atomic.rooster52]

15:01 ah, so this whole suit is just a glorified phone charger.

[@Ihateithere_studios-va]

9:00 WHAT DO YOU MEAN BY YET

[@n7angle856]

I don't know if it is relevant, but you can make the hands quite easily. Have your organic hands outside of the robot hand. Use wire (that suits the specs) as tendons for the robot hand. Have the wire be controlled by a power source, for my bachelor theses this was stepper motors due to it being for an other application. Then use flex sensors in a glove to registrate the movement of the fingers, which the power source will react to. The robot hand should mimic the actual hand movement after calibration (I set a min and max value at every boot up and extrapolate the data). You probably are way beyond this point or found a better solution, but just wanted to help spark some ideas. Awesome video.

[@gobbleygourdiscursed6782]

Make the hev suit next, thats the next power armor

[@C0lbyte]

7:26 Every single amazing ideas and inventions that could change the world (dont know about a Fallout armor 😂) It always fall back on power. I hope those engineers and scientists are working hard on making alot of power in a little box. But other than that. This is by far the coolest thing i have seen in years. How amazing it must for you guys to work on such things.

[@qtheking5915]

00:12 In the games the suits kick you out when they run out of power, the show isn't true to the "source material"

[@blockingclaw5475]

Well in some of the games you can still be in the suit when it runs out

[@shaider1982]

​@blockingclaw5475 I think in Fallout 2, you still are in it

[@ilikewaifus5558]

None of the games do what are you talking about?

[@omoroburns2172]

Have you considered that that's a game mechanic because getting stuck would be unfun?

[@jamescarranza420]

No it doesn't it just makes you move really slow you can't Sprint anymore

[@solarflare623]

I think if you’re gonna make it gas powered you might as well swap the fusion core out for some dieselpunk looking thing. The default suit already looks plenty dieselpunk

[@CR_Weezy]

9:03 I laughed so hard at the yet*

[@lathanchurch8352]

If anyone could figure out how to make fusion cores real it would be a youtuber

[@cody1570]

Cant wait to see how you guys tackle the hips and ankles. Knees and upper foot are easy. The real question is beating that rigidness and allowing for torso twists or even just walking by raising the legs up off the ground even. The hydraulics alone on the hips stumps me every time I think about it without being too bulky

[@teddybeargamez]

I just got into fallout 3 and its AWESOME it makes me more excited for this

[@Atherax]

I've been putting off watch as I didn't have time but I just binged the first 4 and I gotta say this is the best thing since the iron Man suit, and hopefully with what was learned from this and future projects in a few years that could be revisited and maybe even possible 😅

[@freescape08]

21:20 Dual hybrid, actually. The hybrid system has a hybrid backup.

[@DrakeSteele]

This is crazy cool! As a huge Fallout fan, watching this slowly come to fruition has been really satisfying. It's sad it can't be done completely electrically, but hey... without the timeline shift in the 40's, we just don't have the fusion tech to pull it off. Next best thing, eh? Fantastic control scheme, though. Love the pressurized cuffs with the motion controls. Can't wait to see how you do the "legwork" for the lower half. XD

[@Kept_Burrito]

You guys need all the support! Good luck series is coming togheter relly well

[@ZapProd]

Can't wait to see a nice optimized compact and efficient revolutionary suit all finished up in a few years! Feels like this is just a step towards a real solid aluminum/steel iron man exo suit

[@mirochlebovec6586]

Wow those pressure cuff based controls were my first thought! Glad you are including that. Also it would be cool if the power applied by the suit was proportional to the pressure increase in the cuffs eg. the suit pulls harder when you pull harder. Also how is this not a lot of progress? I mean this is probably the most complex powersupply you guys have ever made! Can’t wait for more.

[@Donkie76]

Hey by the way in the show you cannot operate power armor without a fusion core but in the games and cannon you still can use it without power you just move slower and are more cumbersome
