My little experiment to shield a candle wick with aluminium foil collar so that it can be re-lit without burning down too short and later drown in molten stearine. A somewhat successful test I would say :)

My first cuts with Mafell MT55 18V track saw on Festool MFT 3 table. I discovered some "false notes" but in the end the fat lady sang loud and clear!
Portable? REALLY? Festool MFT 3 a good compact living workbench?
zhlédnutí 402Před rokem
How portable is the Festool MFT 3 REALLY? I live in a small apartment and need to set up a workspace "from scratch" each time I do any work. This involves moving stuff out and in of the "hallway" of my house. Is the Festool MFT 3 good enough for this usage?

The Festool MFT 3. Almost ten thousand Swedish crowns. For what? A bit of squeaking and the Repeatable square cross cut! The squeaking we can fix with a bit of oil. The repeatable square cut, will it make me into a more efficient maker? Only time can tell. I have stuff to build! Geronimooo!

Thanks for the vid! I found a pack of these at a thrift store. Cost 3 bucks....might be worth to order some ink.
Worked pretty well, thanks for the technique. Theres still patching, sanding and painting so no matter what its a good amount of work, but this definitely kept the damage to the drywall to a minimum.
Thank you for the video it helped me because I wanted to clear my watch hestory to keep my recommendations blank to be able to focus and open only the videos I downloaded, but I didn't want to lose the watch history . ❤❤❤
👍👍👍
This works. I messed up the f1st one, but the 2nd came out beautifully. Thank you for posting this video.
now people are making videos on what not to do !
Awesome thank you 🙏🏻
Next time before making the video, read the F**king manual. Some audience(like me) do not have time to watch you screwing around. Thanks.
It would be nice if the json file had the video_progressed data to calculate actual time watched. Edit: Is there a way to get this information from google/youtube analytics, or some other way, to calculate actual time watched (past the provided 7 days)?
Det viktigaste är hur den sågar tjockare ämnen.
Bought this thing 2 years ago. I knew I have the track guide for it but don't know how to attach it. Ty
Thak You man!. Very, very usefull and clean explanation!!
I find that a french press works just aswell if not better. Just pour in warm milk and less then 20-30 seconds you have 1st class frothed milk. Just block the pouring spout with a tea towel to stop milk from foaming out.
Great video. Is there any chance that you know how to align błąd in einhell ts-tc 2000 u ?
Great video. Helpful (and entertaining!)
short and sweet. thank you.
This would be a fantastic way to solve thee puzzle if you were both thinking the same way. But imagine for a moment that you hadn't explained your solution and instead had given us the board (post-coin flip) to look at in your video. Would you reasonably expect that anyone in the comments could guess your intentions with the message you've left before your explanation, and find the key?
Thanks, this still works.
Music is louder than your voice, difficult to watch for that reason
Each was carefully placed. Carelessly turn over the coin on the key.
Hinged on the edge of a knife.
But what if it doesnt start with 50 heads and 50 tails? it never said it would
Its random so i guess it might be aligned
I thought i was getting a review of this pen. Reading the comments here from many of the people who had the same problems as you made me 🤔. Can all these guys really be that dumb? You wasted 8 minutes of my life not counting the time it took to write this comment. Come on guys, its not rocket science.
Ok but what if the board already have the key under the right square if you flip a coin it will give a new answer and you have to flip a coin
Sucks that nobody has answered this. I have the same question. Warden has a 1:64 chance of picking the location that's randomly encoded. How to not change the encoding if must flip one?
In that case we just flip the top-left corner position, the zero. I'll explain it first then verify against the XOR logic. Remember that to determine if a bit position (bi) is set or not (set means equals 1) we count the number of heads in the positions where the i-th bit is set, if it's even it's set. This means we never count the first position no matter what it is because it's binary representation is all zeros, you can also rewatch the video to see that the top-left corner is never counted as part of the sets identified. Now to prove this, let's say you find the board pointing at position 0100101 and the key is in that position, then you want to encode from 0100101 to (itself) 0100101 to know the position you want to change we use XOR, and anything XOR itself is 0 (0000000), because nothing changes and that's the position you want to flip 🙃
Couldn't find this info anywhere else. Thanks!
love the video, so timely, just got the same pen with no cartridge. eyesight not good so didnt bother with a wrench. Has anyone ever found the refillable cartridges for this pen please? btw new set now costs over $200.
If you don’t know the orientation of the board when it was flipped it doesn’t work…
The best tuning video for this table saw so far. Thanks and congratulations.
Very nicely explained. I came up with exactly the same solution (and I have now checked the Stand up maths video where 3Blue1Brown is colaborating, and they also end up with the same soluion). I have made a web page where you can try it out. I cannot post URLs here (comment will be deleted), but here it is: mathpearl tod moc slash coins (but reverse tod and moc).
the only problem is that this assumes both prisoners are aware of this agreed upon communication method or encoding, but there's no way for prisoner one to convey the info to prisoner two so unless they had prep time for the puzzle to establish that it still seems impossible
Covered in the 3Blue1Brown video at around 01:10 - The 2 prisoners may conspire ahead of time if they want, but the Warden also knows exactly their strategy.
Fascinating how you explained this solution! I have one question that may seem too simple to even consider but for this riddle and your solution, it would be THE paramount piece of information to make this work. If the chess board is sitting in the middle of a table with no chair (or alone on the ground) how do you communicate the direction from which to view the board to the second prisoner?
i guess the letters and numbers on a chessboard
An excellent meta question. Strictly speaking, 3Blue1Brown should’ve explained that the board orientation is a “given”, and that the prison authority would not mess with the board orientation between the two prisoners, etc. 👍🏻
The prisoners can also communicate before hand. They might determine the orientation of the board by relating it to some invariable component of the room. The door for example. Now if the jail keepers were to turn the board 😭 idk
Simple and objective. Thank's from Brasil
What?
How you adjust the laser?
Superb quality throughout, easy to assemble. I found the saw to be highly accurate and a delight to use (I am a homeowner using this saw for various projects). I attached the saw to a folding mobile stand to save space and that works great czcams.com/users/postUgkxPeGkHOMe05FySypTOvYumxMn-xi39oRe as well. However, you have to be sure the saw is securely locking in position before collapsing the stand. I've had many of the brands over the years and have come to point where I only buy Bosch, the extra money is a small price to pay for the quality and ease of use. Treat yourself to the best.
Гавно блят редкостное. Это не метабо это хуябо
Does this method still work if we operate under the original premise that 3blue1brown posed though with the "Warden" Being able to play defense by listening in to the strategy before he arranges the board? Couldn't he just make every Coin be heads or all of them be tails and it would throw off the encoding?
It will work no matter what the warden does. If the warden sets it all heads, which is 000000, then just flip the coin on the key.
On a review, someone stated the scoring cut doesn't exactly line up with the final cut. have you noticed this?
I have both the cordless and corded mafell tracksaws, They both move the blade 0.1 mm when they score. You don't notice it. If you do notice it, there is a fault with the saw.
How big is a Protea filter?
5 years later and you helped me figure out the same exact problem! Thank you so much
Once it is setup, you can easily pull the parts off and put them back on at will. It is not meant to stay assembled. If ALL you are using it for is cross cuts, you are missing out on 100 other functions of the MULTI function table, friend.
It will be easier and easier, each and every time you move it. You will become strong.
what if the key is allready under the square, that the board is presenting before the flip? can you change a coi s value without changing the 010110 outcome?
You would flip the coin in the top left corner, representing the value 000000. This would not affect the value of our board
Is this correct?
Truth is always in the eyes of the temporal observer. Too much time is spend to defend believes (that stick with a restricted knowledge base) while another viewpoint of the same object is possible and enriches your total knowledge of the same object (czcams.com/video/oWfFco7K9v8/video.html). Although the fight for the truth can be a useful tool to understand the game/world/total object, you should just see everything as a means to get to a goal: what do you want to avoid, what do you want to be accomplished. The truth just "is", but the interpretation of its meaning reveals the goals of the actors. And the goals must be checked against morality, not the truth.
I find it unlikely that a pair of prisoners that are smart enough to figure this out aren't also smart enough to avoid going to jail.
got a point! XD
This is pretty big-brain
Very helpful video. Thanks for posting mate. Does the dust bag work well? I read a few people complain it gets clogged easily? After using it a bit more I’m guessing, are you still happy with the way it runs on the festool tracks?
You still have your fingers? Lol
This is a very estupid video!!!!
Thank you!
