The next phase of this project is to put some servos and instrumentation on the boomerang so that it will be able to control its own flight path and steer itself home. ;-) Also, the long form videos are a nice change. The extra touches done in editing are cool.

Great video Tom. One difference I was noticing between you throwing of the boomerang and the machine launcher was that you was stood throwing the boomerang and the launcher was sat on the floor meaning the launch had the height already when yourself was throwing it.

Cool explanation on 'gyroscopic-procession' and why Boomerang curves. Didn't know that!

Looking at a boomerang as used to actually hunt food, the most obvious thing about it, after that curve, is the difference in the length of the two 'legs'. This difference helps to steer the boomerang in flight, and shape the instrument's flight characteristics. Nice video. Thanks for putting it up.

I love how you go from a fancy "Laser guided" CNC machine to 2 outdoor chairs for woodworking. Now I can relate to that type of woodworking haha

I love your elegant and simple release concept. Very nice! You definitely could have just tried a few (hundred) more times and got one throw to hit the launcher, then just showed THAT one, but I LOVE that you show the whole process, and how you worked through it, and (probably) most of your attempts. Definitely NOT a failure, BECAUSE YOU LEARNED FROM IT. Way to go!

as far as i know boomerangs actually need the wind to really come back to the thrower.. and maybe your catapult is just a little low? after all humans throw the boomerangs from shoulderheight.. and a little downwards too.. so they have more clearance before they would hit the ground.. interesting project, though! :-)

Well done. As a long time boomerang thrower and erstwhile manufacturer (Rangs Boomerangs Australia) I commend your inventiveness and persistence. The release method approaches actual genius. I'll be sharing this presentation with my boomerang buddies.

Hi Tom, I'm a boomerang-thrower myself (member of the German National Team) and I'm pretty impressed with your construction of a boomerang-launcher. But I'm also happy to see that you like to throw and catch boomerangs without any mechanical construction. Do you know that there is a British Boomerang society, which organizes tournaments and building-workshops. They also have throwers that like to experiment with boomerangs as well (and build a vertical wind-tunnel for example). Look the British Boomerang Society up on the Internet. I'm hoping to see you soon on a boomerang-tournament to exchange some crazy ideas about boomerangs with you ;)

you can also add a coin on the tip of the boomerang so it spins longer. I had to do that to my 3d printed boomerang

Not a failure. Those shots of the boomerang describing lazy, gravity-defying curves are just beautiful.

6:30 "about six and a half minutes into this video..." that was either a good guess, or well edited 🤔😋

I throw boomerangs for sport and collecting, and I'm amazed that you made this work. I had my doubts, but by god, even my hobby will be taken over by robots. Excellent job!

Sweet vid it was like watching Mike Boyd meets Smarter Everyday meets Tom Stanton!

Awesome Video! Awesome Build! I too have thought about possible designs for a boomerang thrower. You did great. That cup of tea after all of those throws gave me a good laugh

The go-to tuning I see members of U.S. Boomerang Association (USBA) doing is taping a coin-size weight to the wing-tips. Sometimes amateurs use an airfoil that makes too much lift. I like when a light Boom spin slows down at the end and hoovers down for capture.

I do believe i have a proper boomerang for ya. Love the invention my friend. Wish you were my neighbor, i could at least hold the camera for ya lol. Every time it made a full circle and landed in front of you i would still call it a win. The launcher did it's job. That boomerang needed a little bit of breeze to push it back just a bit. I don't think hitting the ground made it fly any different, i think it was simply the change in wind direction. This test would have gone so much better in a huge arena with dead air. I know, not practical or feasible. I've thrown 1000's of times and i only go out first thing in the morning or just before dark when the breeze is at it's lightest.

Finally, your explanation was better than any other (how boomerang works) search result I got

Your excitement when you caught it for the first time made me want to go out and buy a boomerang right now

Some suggestions after reading the comments: Put the launcher on an elevated platform and when proper release angles are established, fix it securely. Play with the location of the pivot pin to achieve faster rotation if possible. Use a ready-made plastic boomerang. There are a few decent two-blade plastic booms made. Lastly read up on tuning boomerangs for better flights. The light plastic ones respond very well to tuning although they won't hold it for long. I have no doubt that it is doable.

We have to appreciate that he stood up, walked to the boomerang, picked it up, walked back, put it in, make sure the camera is set, sit down, lunch x 89 times. Thats a lot!!

Love the idea. But the boomerang can swing a little bit on the hook so that the angle of attack can be different every time. Maybe place a board (or 2 boards) nex to the boomerang so it will stay in the same plane every lanch

"this is the one, I can feel it." **Throws it straight into the ground**

Well that's an A+ for persistence! Great video!!

Nice video! Long format FTW! Worth mentioning that it's very important that you show the failures, that is the most teaching part! The successful part of your videos are more for our, and most probably yours, enjoyment, but the teaching part is on the failures and your workarounds! Love your videos!

It is totally easier to scale up to rediculous sized boomerang with trebuchet. No motor drone for quick recon, anyone?

Quick suggestion. Spray paint your prototypes a high contrast color so they can be seen better against the sky. Many shots the woodgrain has low contrast with the sky and they're hard to see. Love your vids. Killer series of projects. Thanks!

I can just about build a paper plane but your various and imaginative experiments are compulsive to watch. You must have one hell of a lot of spare time.

KZread recommendations got it right and gave me this vid today! Amazing! Didn’t know how a boomerang worked!

[circular(spin)/ lineer velocity] ratio is also important. if you would make that hole closer to the elbow(center), more kinetic energy would go to circular and less to lineer motion. That something you could try. That boomerang you can throw it with the lift arm, dingle arm or even elbow. And elbow you can make more spin.

That effort for this little experiment is very impressive. Great video. Thank you.

I love a simple solution to an issue. My first thought was a timed release mechanism using an actuated axle or something but I think it would be very difficult to time it. Your solution guarantees it releases with the right pivot. Brilliant

I admire your perseverance and I love the work you put into editing! The catapult-timed-to-music bit was cool!

I was thinking that your axle could of been a retractable pin powered by an actuator, however ever your solution is even better!

Tank you for teaching physic this way . It is fun to watch and you learn something . Greetings from Germany .

I like that the launch was synced with the music

I do like the longer all in one video projects!

Nice to see the A350 on approach and the climbing bird in the sky in your second throw shot, I really miss the time in my life when I could spend days building something completely useless just to see if I could, good on ya.

As a boomerang thrower I appreciate your job. What a very fun project , congratulations !!!

Love this format, and as an Australian, love this project even more!

Excellent. The pursuit of knowledge.

I think sometimes you get so focused on your goals you don't realise how amazing what you have achieved is.

If it circles behind you more out of wind to the right of wind. Circles in front of you too much out of the wind. Aim more left.

Brilliant project and video

I never know what you’re talking about but I can’t stop watching

your diligence is impressive.

When I was a kid growing up in Australia in the 70s there were a lot of good boomerang throwers around. It was a bit of a thing back then to practice - I guess it was our version of frisbee. I was pretty good at it myself. I reckon one of the problems with your machine launcher is that it is too close to the ground. When you throw a boomerang you are throwing it from about 6ft high and you launch it in a bit of a downward motion; the aerodynamic lift then kcks in and makes a better arc. Maybe you could lift your machine up off the ground and get it to release a little later.

That was a really interesting project. It would be nice to hear about the design and options of the boomerang itself. Great job and well done!

This new format is awesome!

I appreciate your hard work bro. Keep going, best of luck

Still did what it was supposed to do, so good job.

Tom Stanton,the man that simplifies !! Totally love this video even though it failed

Liked this format allot.

I was sat here almost shouting at my TV "NAIL THE BLOODY LEGS ON!" lol. It'd certainly help your consistency.

I did a lot with boomerangs 50 years ago, great fun. I always pushed the daylight a bit too much, and then the game became dangerous! I am really enjoying your experiments, and I find I have touched on quite a few of the subjects which just makes it all more interesting. Keep it up :)

Thanks Tom, great video.

Put bigger wheels on one side of the trebuchet and make a bigger boomerang, use the trebuchet to launch it. Weight instead of torsion for control, larger boomerang bends less, weighs more, less susceptible to wind? Loved the vid, would thumbsup more than once if I could

I’m very impressed with your release method. The biggest advance for you would be a base to hold the catapult at a steady angle. If the release is consistent then the next variable is variations in wind and turbulence. Look for a bigger field, with nothing up wind of you to ensure clean laminar air flow. Those trees in the picture would have given turbulence. The smaller the flying object and slower the air speed then the more it will feel and be effected by, the turbulence. Of cause some windy days are more gusty than others too.

@denbecr49

Excellent observation. My lifelong kite obsession taught me how disruptive distant upwind obstacles can be to getting a kite to launch. Another unnecessary variable I see is the ground level launch. There is an abrupt gradient of windspeed from near zero at ground level. You can see it by blowing bubbles at various heights in various strength winds, preferably in wide open spaces. Watching the relatively slow progress of dried dead leaves along the ground is evidence as well.

If you rigidity mount your catapult you should get consistent results. If you make that mount adjustable you can fine tune. I always like your videos keep up the great work!

Good job so far...but for one...make that thing stable not rocking when you launch. Second, make the arm just a bit longer and third, the stopping blade stalls as it slows down and generates drag which makes the other wing come up and around by means of inertia of the second blade which you should balance angainst the drag by making the tips of the blades a little heavier in your case (it just seemed that your boomerang was not spinning as fast as it should). I think you can see what I'm pointing at. Ps. It will give more stability and a longer flight time, though it will also influence the shape of the flight.

Dude thanks for the quick breakdown of gyroscopic precession!!

nice informative vid Tom

If you ever revisit this concept, I recommend you cut identical notches in all blades of each boomerang.

Hey Tom! Great work as always. The fact that you achieved a couple of launches that ended up within the 2 mtr catch zone is really good. Please consider that you are not imparting a twist upon release as you would with a human wrist launch. With the catapult it is quite linear.

the simple releasing trick is very ingenious

Really enjoy your vids. Please make a wooden dagger and launch it at an apple at 5meters! The catapult can be used as is, just add the 80° notch to the handle of the dagger.

Sit down, get up, chase the boomerang. Sit down, get up, chase the boomerang. This sounds like a great workout tool.

Its a lot of effort that you put into this and we don't see it....specially when you showed about 20 launches one after another Greatly appreciate your effort, great vid ♥

Right in the beginning, the camera's frames per second matches the rotation of the boomerang, pretty cool! 1:44

when i used to throw one when i was little, I would be about 100 feet back in my yard and chuck it directly at the right corner of the house. It would lift before hitting the house, go left, and come right back to me every time. It was probably heavier than that one, and was a true boomerang shape. Now even though I could bring it right back, it was painful to catch! Also I'll note that the secret to a proper consistent boomerang through is a hard flick of the wrist, so it is no surprise you had issues with the catapult. You need the rotational force to be enough to carry the thing back to you

I think having the launcher hold a stable position between launches would be essential for your repeatability. Each time you're changing angles in an uncontrolled, unmeasurable way. Just take some threaded rod and screw it down in the corners to create the angles needed.
