Dope Tech Episode 2

<<@QuironPinheiro says : Well we are one step closer to lightsabers>> <<@IlluminatiBG says : I hope this is not an April's fools, as it seems interesting, also it is interesting how much the blade needs to move. What if you use toothbrush vibration motor instead, the movement will be tiny, but will vibration make cutting easier, like cutting in one direction.>> <<@rollotomasislawyer3405 says : This is a solution in search of a need.>> <<@PewpewBoomboomm-pc4mk says : Wow....I really love this knife I want one>> <<@sneklover69 says : John Rekesius already said three things, but I want to point out the locking mechanism and the thick blade with teeth milled in the side, happy late april fools>> <<@manjitrupbikram says : Like going for a swim on a really cold day, if you know what I am talking about.😂😂😂😂>> <<@brawndo8726 says : Everyone pray this guy never gets a 3D printer and learns how to use CAD software.>> <<@SomeOne-mw8zl says : menschen die gegen waffen sind, befürworten dass frauen und schwache menschen sich nicht verteidigen dürfen.>> <<@dapooch2521 says : Pretty awesome idea have you thought of using a solenoid instead of a small motor?>> <<@jeffprice1831 says : I think you would have better luck with a spring and locking mechanism but hmmm a battery might take up some space as well as the charging mechanism , give me a couple days and I think I can come up with something>> <<@hjacobson22 says : Like swimming on a cold day 😂>> <<@christopherdaniel5919 says : You must be joking. MUST be... 🙄>> <<@terrariangamer5335 says : It might be beneficial to use a gear ratio>> <<@greenbillugaming2781 says : Assasin creed hidden blade designs already achieved this some what. Have a look on youtube.>> <<@toutalegout says : why?>> <<@toutalegout says : why?>> <<@Akamo. says : I know this is probably an April fool's Video. But honestly I would buy it as a novelty item.>> <<@pjpcarv says : I would have made the knife serrated at the back and use that for the gearing. The motor +gear could end up being a sort of crossguard on one side. As it is, the hollow blade will easy to break, no?>> <<@AndyPanda9 says : Use a crank to make it reciprocal, like a sewing machine, so the blade stabs repeatedly. You just swing it past the enemy and give him 20 stab wounds in a row 🤣>> <<@belabohlen6156 says : Make it an electric saw also usable as an edc automatic knife, probably possible>> <<@wochenendedestodes9015 says : Warum keine Gewindestange mit etwas steileren Steigung wie ein gewöhnliches DIN Gewinde. Die verschwindet in einfm Gewinde in der Klinge und hinreichend schnell ist es auch. Den Motor könnte man dann direkt oder über ein Planetengetriebe anschließen. Zudem könnte man das ganze mit einen zweiten innengewinde mechanisch vom Motor entkoppeln. Und das ganze wäre selbsthemmend.>> <<@afkafkafk says : need joerg as the next protagonist in the next assassins creed game>> <<@d.i.l.l.i.g.a.f says : Damn, first video of yours I have seen in ages, Must be close to 6 Months, thought you may be off on some more TV show projects around the world. But No! For some reason YT has disabled my Notifications on Your Channel, B'stards>> <<@riddickraymond7067 says : It's like a bad Assassin's creed blade I don't think there is much you can do to improve it.>> <<@alexanderivanov3771 says : if you combined with a sheet, you can conect the sheet with the gear and in one direction it will open the blade , but in other the knife will go out closed.>> <<@kadmow says : this mechanism is how dial calipers work... the rack is inside the back of the "rule" - shielded from the front - it tends to star clean, but then instruments like that are not thrown into the dirt..>> <<@bearbarre6435 says : Try using the motor and battery that makes a cell phone vibrate. They are very small and spin very fast.>> <<@okayolamax2min345 says : Awesome (redundancy?) Makes me think maybe a gasoline powered... or atomic driven blade😎>> <<@joshbrown811 says : I would 100% purchase one>> <<@GERALT_OF_RlVlA says : Love the idea, would love to see prototyped in metal!>> <<@endelvor7489 says : This look like the hidden blades models. They have gears and some spring action to eject the blade out, sometimes two parts blades and they are very very cool. A long blade with this mecanism will be very intersting... and i really want to buy one kkkkkkkkkkk (i m from Brasil, forgive my english)>> <<@Schattentoeter92 says : Modern hidden blade from Assassin's Creed>> <<@Flyin_Raijin says : Like the hidden blade from assassins creed>> <<@bonek350 says : I think it's worth exploring the idea. Put it through some comparison tests. It's fun at least if not truly useful or better.>> <<@codyfreeman2556 says : Depending on the size of the handle you could rotate the drive gear 90 degrees and have holes in the middle of the blade to mesh with the drive gear.>> <<@jeffreybarton1297 says : You could make a serrated edged blade, where the serrations acted as the cog notches, that way you'd remove the dirt trap in the middle of the blade, and the need for a thick middle section on the blade, but still retain the essential mechanical action.>> <<@soulwynd says : I think you're better off using a linear induction motor instead.>> <<@whitewittock says : would this be classified as an automatic knife>> <<@mcsaatana1614 says : you could keep that as gravity knife type and simply make button to lock the gears in place when its flicked open..?>> <<@DogDad303 says : Love the design. Will be illegal in the usa though as is it assisted opened. I may be wrong as im uneducated on the subject. I believe thats the case though>> <<@tiberiu_nicolae says : Can you make one that extends the blade with a shotgun primer?>> <<@daviddavidson2357 says : Assuming this isn't a joke video, you could try to use a solenoid and a two locking mechanisms. When the knife is in the locked position you press down and unlock the knife, the solenoid propels the blade forward and into the second locking catch which holds the blade in the deployed position. Then to put the blade back into the handle you push down on the second locking button (mechanically joined to the second catch) and the solenoid can pull the blade back into the handle. Kind of like a gauss gun, but shooting a blade forward a few cm and then pulling it back in. You could also have the blade fall back into the handle under gravity. Not sure if this would be classed as a gravity knife/switchblade though. However if a small permanent magnet was used to hold the blade in the closed position and it held the blade against the force of gravity then it may not be. The solenoid coil could be built into a round handle. The catches themselves could act as switches by being made out of metal and contact a metal rail when they're pressed. You could either use a tiny microcontroller on a round PCB or passive components on a round PCB and have it put into the hilt, then power it with two 'gumstick' style RC helicopter LiPo batteries that go along each side of the knife and are surrounded by the handle and coil. Handle can be 3d printed out of carbon/glass fibre filled filament for a prototype.>> <<@erebostd says : Jörg, du solltest dir wirklich einen 3d Drucker zulegen. Du würdest so viel schneller iterieren können!>> <<@sideswipebl says : Make it go through both ends.>> <<@racsofischer7601 says : honestly, I think that you could put the teeth at the back of the blade so they look like a serrated back, and then use a worm gear spinning very fast and aligned with the spine of the blade to extend and retract the blade.>> <<@austin123457 says : I think adding a coiled spring within the mechanism could make that work even without the motor. Giving it enough tension and a locking system so you press a button, and it winds the spring down turning the gear, extending the blade. Then you can either turn the gear and sheathe the blade, or press it to sheathe it, "Recharging" the coiled spring. Could even add a small release button that decouples the spring and gear, so if it wears out or goes out of wack, you can easily rewind the spring to the proper tension, sort of like a drum magazine. The button could interface with two parts of the blade, perhaps at the front of the gear set, to keep it sheathed, and then at the rear, to keep it extended, so you aren't putting undo stress on either the motor if you go for it, or the spring if you go that way. I'm not certain on the practicality of this design....but...practicality sucks, making cool shit is way better!>> <<@khoroshen says : I would like to see a crank and conrod design... might be difficult to get a reasonable stroke out of it, but imagine the action when it is motorized 🤣>> <<@SlingshotShooters says : It is a daunting task to come up with a new knife of any kind. It would be a cool miniature for the pocket. Love the innovation!>> <<@cptblackops says : JOERG! please look at iamdeepainreborn he is on YouTube and makes hidden blades from assassin's creed with and without worm screws! He has been making them for years and his disassembly videos might be able to shed some light on the best way to go about it. Hope this helps!>> <<@E.mp.clypeus says : You should check out @rawice511 He makes assassins creed blades and otf’s. He created a design that is very similar but he has worked out some of the problems.>>
