Loved this one! 2 things that caught my eye: A) Ranging. 8 separate lasers that converge at a fixed distance, from what I could see. The 8 lasers only converge at one distance, with a fixed mount. If small X-Y actuators were incorporated, along with range finding, all 8 lasers could be variably focused on an arbitrary point at any distance from the emitter, thus maximizing the delivered energy. An oval pattern on the test plates seems to indicate that the test plates were not at the optimal distance. A perfect(ish) circle would be what I would expect for perfect range alignment for all 8 lasers. B) Dead target. If the target hasn't moved for X amount of frames, then I'd call it a low priority target, i.e. don't shoot. If it moves, shoot again. Doc, you've gone full blown Real Genius in this one, well done!!! (if anyone doesn't know '80's movies, just look it up and watch it. GREAT flick!) Edit: 1 more thought. Instead of calling it the Kill Switch, why don't you go with the military nomenclature and call it the Master Arm? "Master Arm on" means weapons hot, "Master Arm off" means it can't fire.

My dad got to the proof-of-concept stage of inventing something like this when I was a kid. This was the mid-90s, He wanted to make a sort of anti-insect laser turret. He didn't get as far as acquiring lasers or anything. Laser pointers were just starting to become cheap, and he had the idea of an array of laser pointers collimated (right word? Collated maybe?) into a single narrow beam. I remember a sort of analog circuit with a bunch of op-amps and odd ICs to detect and target flying insects. Looking back on it now, that's basically how coldwar era targeting and fire control works.

[@ET_AYY_LMAO]

this is actually brilliant, you only really need to disable the CCD or CMOS censor in the FPV camera to take out a drone, you could maybe even augment it with a passive radar system for acquisition.

[@dionh70]

Considering the very low likelihood of the drone camera having sufficient optical filtering in place to protect against the amplitude of the laser light hitting it, that should be simple and fast, as exemplified by the damage suffered by StyroPyro's camera while recording operation of the so-called "hair removal laser" that he bought from Temu. But. This also requires that the laser emissions enter the lens within a specific angle of attack, and if the drone being targeted is moving perpendicular to the laser emitter, then its lens is very unlikely to catch enough light to damage the sensor sufficiently, if at all. That being said, if a battery of these laser cannon were set up as a defensive emplacement, aiming nearly directly at oncoming drones, then the optical sensors on the drones would be far more likely to be exposed to the laser beams. Then the defender need only hope that the drones aren't using GPS as a guidance system in addition to or in tandem with video piloting. Finally, there is no such thing as a "passive radar system".

[@ET_AYY_LMAO]

@@dionh70 There absolutely is such a thing as passive / parasitic targetting radars that use radio emissions of other crafts as well as reflections for target acquisition. If you are in doubt about what it is, go read the wiki page about it :) You dont really need to hit the CCD directly, just cook the FPV camera with moderate heat. Most FPV cameras go glitchy just by being on without sufficient airflow around them especially 2.5watt ones.

[@ghosttheoremproductions5469]

One of the biggest difficulties in this type of tech is the need to have your beams align/converge at various distances. This requires determining distance and precisely moving each individual emitter. The precise and repeatable movement of all emitters can be handled by a single driver if you mechanically connect all pivoting emitter bases to eachother but it requires considerable precision and tight tolerances. Distance can be measure by a ranging emitter, multiple cameras for binocular (or greater) vision, or a combination. Even then you have the issue of atmospheric distortion once distances become great enough. That distortion can be measured and then phased out but this requires on-the-fly lens adjustments. - It's a simple idea in concept but in application it very quickly grows into a rather difficult task and considerably increases costs. Nowadays, the real-time computation and machine learning based target selection is the "easy" part, haha.

All of the new training of course also taking humans into account and make sure they are not evaluated as targets. And the test for this: In the middle of nowhere, with high speed drones and pro pilots. A nice variation (needs more precise training and aiming): Take out only the rotor blades.

I'm surprised he hasn't used a laser to carve Nazca-Line type images into surface of Moon yet... Give him time.

[@grant-is]

Absolutely incredible video, best yet. The entire team did a fantastic job and I cannot thank you enough for the discussion regarding paid sponsorships. You are right and I am so glad you have a patreon instead! Excited for your future videos!

[@zbynial]

Brilliant material. Thank you. You don't have to add a distance measuring device to apply a correction of laser position according to distance. Brilliant

[@ghostindamachine]

Incredible technical designs made look super easy. It is just incredible how much knowledge this channel communicates and shows.

[@jacksplague3050]

Your guest's explanations were great. I actually have a little bit of experience with YOLO, and he definitely explained it far better than I could have.

[@stepannovotny4291]

I finally understand the I component of PID in terms of feedback loop and system latencies! Thanks for clearing up years of confusion.

[@falcon_three_fifty]

The terms used to describe the actions of aligning a gun barrel to point in a desired direction are "traversing" and "elevating": Traversing: The horizontal rotation of the gun to align it with the target Elevating: The vertical movement of the gun to range it to the target The process of aligning a gun barrel is known as gun laying. Please remember the terms of pitch, yaw, and roll are more appropriate when referring to the movements of a vehicle relative to its direction of travel, like a boat or aeroplane.

[@slots1407]

Cameras use pan, tilt & zoom (PTZ).

[@falcon_three_fifty]

@@slots1407 and if we were talking about a telescope it would be azimuth, altitude, and focus. But with this laser, which terms do you think are the most appropriate to use? 😄 The terms for a camera, telescope, or a weapon system? 😆

[@jamessheridan88]

I love this channel. He even answered the root cause of an issue we were having with one of our designs.

[@TechIngredients]

Great!

[@PinePondCTDevilsHopyard-fy3hj]

Chris did a great job, keeping his explanations simple enough for me to get basic knowledge. Looks like Terminator T2 is here.

[@pgjuzek]

dud, if there ever was an applied physics promotional video... I went for CS almost 20y ago, your work is jaw dropping, I tip my hat off to you mr

[@Bigshooterist]

Your videos never cease to amaze me. They're always exciting and whenever I see a new upload, it's reason to celebrate. Thank you for the INCREDIBLE effort you put into these.

[@DanishValkyrie]

if you pause at 48:33 and use the "." hotkey to go frame by frame through the next second, you can see the laser quickly point down at 48:34 as he walks out. Interesting stuff!

[@jakestanbro959]

[@topfeedcoco]

What a fantastic follow up video Sir. I've been rather fascinated with this line of study ever since you illustrated it with your first vid. Thanks TI

[@kloneo]

For the AI laser project alone. - A vid about the start of project, why you want to try, what the ideas are and the selection procedure of the laser. Why you are thinking about buying this laser, do we need to watercool? Is there some choice part over the counter, or do you need specialized lenses. How you came to conclusion to ask at MIT. 10 min vid. - A vid about contacting MIT and how you select a partner and a how does that work? I don’t know but would like to know. - The main vid. - A 5 min vid about the costs of the project. Some of these items must be expensive.

[@smegheadGOAT]

I am glad you let it burn a bit, brings excitement to your digital content.

[@Benoit-Pierre]

From expérience, with this kind of danger, even if your table is stable, you should not be within 3m of the table when system is armed. Any human can fall on the for many random reasons. You should use one table to lay the prototype, use cables, and have the control table at least 3m away. So that any foot or hand issue will hurt the control table but not the proto .

[@natuerlichedummheit]

This is incredible. I never thought that humanity would ever have such a technology!

[@danvds_nz]

I do apologise for not reading through all the comments before posting this... (in respect to not being a "black pill" - if we had volunteer medical/aid personal on the ground who need protection from "individuals and/or groups" who are targeting them this would/could help immensely - automation would make it easier, a human in the loop as "guard" might be easier to start) I have been subscribed and watching your channel from New Zealand for years now. (And also, I am hesitant to bring the "conflict" into the conversation but I do feel it is personally "most relevant") Among other things I teach martial arts. One of our students was compelled to volunteer to help in Ukraine and has served there since the beginning of the invasion. I have seen footage from "under cover" (which was really just some trees that had been destroyed by shelling) with the sound of drones "zipping" past overhead - multiples of them all operated by experienced but hostile operators. It is terrifying in a way that the Terminator franchise could only dream of. How hard is it to get a platform to move fast enough to target a highly responsive and adversarial drone? If one of your local community FPV racing drone pilots was "behind the stick" is it possible to build something that will "incapacitate the drone" - I am magically imagining a scenario where someone can drop a bit of hardware down and a remote operator can then provide them with protection. it doesn't have to completely destroy it just make it un-flyable. (Sadly I am poor but I do think that having a Patreon is an excellent idea for you guys and I applaud your rational of staying true to your purpose)

[@iguessjohn]

That's amazing. A few ideas how to improve the setup. 1. Moving the entire array of lasers seems a bit clunky. Wouldn't it make me sense to have a small drone motor for each laser individually? 2. Does one even have to move the lasers? Wouldn't it be possible to do coarse movements with the gimbal and fine movements just with the lenses or a mirror array. Like sony does with their laser projectors? 3. I am pretty sure that using multiple cheap cameras with different filters would improve tracking a lot. It's much easier for a model to infer position in 3d space with multiple images from different angles. Ml is data, data, data. The more diverse, the better. 4. You don't have to label the images yourself. Automatic classification already exists. 5. Training in consumer gpu is quite ineffective. Renting a H100 or a 8xH100 cluster will be much more effective and is not too expensive. My bet is MIT probably has a cluster themselves. 6. There is a cool series on KZbin about drone tracking phase array radars if you want to go next level. 7. If you want to destroy targets the model should be trained to lock focus on a specific point of the target to keep energy bundled. 8. If you want to go completely crazy make a couple of the laser modules and position them at different locations. You could sync them to attack a target from different positions simultaneously. Feed RTK GPS position into the model as well. Train a model that is independent of the position of the modules. Then you would have created actual factorio laser turrets locking in together at one target. 😂

[@dandan-gf4jk]

3:55 Another fact to be added to the Main Presenter lore

[@ChristopherWanha]

Would love a StuffMadeHere TechIngredients crossover. Imagine having a laser camera with the ability to see behind an object by simulating a desired lens size/shape, and Val Kilmer'ing a target behind/through an obstacle (where the target has an "unknown" location).

[@fluffypinkpandas]

The end game of drones is them having Drone-To-Drone laser wars, making the Night Skies look like Elite II's vipers are defending a station

[@TTAPPER04]

the battery requirements of lasers may make them too heavy to fit on small drones. now a turbo jet mothership would have plenty of juice.

[@jeremymcadam7400]

​@@TTAPPER04 with fibre optic controlled drones you could give them a fibre laser too 😂

[@ricosemple-qn9ft]

This is the most exciting entertainment and education on the internet. This tech is so close to top secret info that I worry about it being grabbed away by the military complex. Maybe try some gold and mercury vapor at that point of convergence of the beam. Then the plasma follows the beam, leaving a trail one atom wide .

[@CrimFerret]

That was an incredibly good explanation of how lasers work. I have a 5 mW helium neon laser. It's maybe 2 feet long. The beam divergence is way less than any red laser diode. In a single room it's hard to tell it diverges at all. This was really cool. I don't know if you'll recall a video of a test where a laser on a moving naval ship tracked and burned a hole in the motor of a moving speed boat. A friend of mine worked on that project. It worked remarkably well. It had to do it with both ships moving in all three dimensions, but it was basically doing what you did here on a much larger scale at far greater expense. I don't think it went anywhere beyond the testing phase because it was so much more expensive and so much less efficient than using traditional munitions.

[@TechIngredients]

Thanks! I remember seeing those clips.

[@berendhordijk2433]

Watch those toxic lithium ion vapors! I Imagine an array of these setups working together could disintegrate objects in single bursts or at a distance. Short (more intense?) bursts could be fired from capacitors, avoiding the need for (multiple) kW power sources (maybe?) Cool stuff! (As per the usual!) edit: first channel I will support. the great content, format coupled with a lack of ads do merit a ROI. here I was imagining you with great (earned/deserved) wealth and on an early retirement, doing all of this highly interesting experimentation ;)

[@karljay7473]

Great demo. Coming from the world of AI, it's very interesting to change the model and have it perform so much faster. One thing about the models is the promise of being able to update the model in real time. Basically a self correcting model that doesn't require reworking on the graphics card. Also, that table looks like a welders fixture table with all those holes, but those holes don't look like standard 5/8". I wonder what kind of table that is and why they'd need such a huge fix up table. Looks like an awesome one, and I want one :D

[@TechIngredients]

Thanks! It's an "optics" table. These can be had second hand for a very reasonable cost. Some are imperial and some metric ie. 1/4" holes on 1" centers or 6mm holes on 25 mm centers. They're stainless steel, and they are VERY useful even if you aren't working with optics, as we demonstrated with our detonation engine video.

[@marsthunder]

Outstanding! I like the idea of bringing in other expert project helpers!

If you want to learn, you're in the right spot, my friends !!! Awesome video!!!

[@bricehoogenboom6483]

Very impressive. Would be really nice to see it being able to once a target is lost, and if it reappears, it remembers what # it was, instead of reassigning a new #. Also once target is disabled, it ignores it. As a car was on fire, it went back to it, even though it was no longer a "threat".

[@yngndrw.]

What a fun project. This project makes me think of the high-speed tracking cameras that they use when testing tank shells. (~1,500m/s) My understanding is that they use a mirror on a galvanometer rather than moving the entire camera, in order to reduce the inertia. I've always wanted to build a tracking camera that can keep up with a racing drone, it's just on the end of a very long list of projects such is life!

[@TechIngredients]

That's interesting. As we progress, the tracking will improve, and maybe some of that engineering will be useful for your project.

[@scotttoner9231]

In addition the physical/material destruction visited, it would be interesting to understand impact to the drone optics - consider FPV vehicles with sensor “protection”. Love the channel!

Congrats on an amazing project.... totally fascinating. The degree of tech involved is impressive, in particular with the fast tracking like with balloons, RC cars and then drones. Proof of concept! Also, a great example of a collaborative effort with Chris involved. Kudos to all. :)
