A lot of REAL progress this week! I thought it was high time that i tried to give you all some context on why i am doing this major redesign that i am working on right now. Im presenting one theory that might explain the motivation behind the decision to do this redesign. Perhaps the Marble Machine X itself is the Local Maximum, in that case, the current process will lead me to that discovery and i will take another u-turn to find the path to the world tour. Probably i will take the advice that has been given to me so many times during the past years: "Why dont you just play guitar?"
:) Hope you all are are having a great day and enjoy everyone! ;) / Martin

    • Redesign?????? am gonna stop watching i sad a million times Martin has a problem ... i wasted like 3 years following this project ........we all know martin he is perfectionist ,but every thing has its limit.. and i think he is doing this because the channel was not for building the marble machine , so he is scraping the barrel , soo it was fun while it lasted .... bye bye

    • @Wintergatan Hi Martin, You're now reaching epic levels of failure rates with the grinder! ;-) People in the comments below are talking about 6 Sigma standards. I'd also mention that you've reached the stratosphere-- you're now talking about aeronautical design levels of failure. See also ideas about "redundancy" in design and "fault tolerance." Airplane safety statistics might also be helpful to get a grasp of how to pinpoint design durability and weakness. Keep striving for excellence!

    • If you had to approach a completely different, but equally complex machine build project in the future, knowing what you have learned along the way, what would you do differently? Seems to me that you might invest more time testing single prototypes of a sub-mechanism before iterating them across the machine itself - that is, for example, build one marble dropper, and test it with a million marble drops. Then you're only fixing one thing, rather than fixing 20 of the same thing, only to find that the fix isn't sufficient. I'm not saying I would do better myself (in fact I know I wouldn't - I simply lack the patience for this scale and complexity of engineering), and it's also less exciting and less fulfilling to be just testing components, instead of seeing the machine emerge of course. Hope this doesn't come across as critique - I'm actually just interested to know how your methodologies have changed across the course of the project.

  • Seems to me that you could have sold even the flawed original version for, say, $50k, and started over from scratch. Regardless of economics, it might have been less emotionally painful than hacking up the machine (I couldn't have done it!).

  • I enjoy your enthusiasm but the fundamental idea driving the rebuild seems flawed so probably yield unsatisfactory results. It would be far easier to make a way for jammed stuck marbles to be removed quick and easy / so the machine can still function

  • It’s NOT Sunken Cost Fallacy. Setbacks and detours are a natural part of the path and process towards any goal. This is a turnaround, not a failure. It’s a necessity for further progression and improvement. The MMX project can’t fail, as it has no definitive parameters for success - it can only be accomplished to a higher or lesser degree in so much more or less time. Of course you should continue. You, me and all of us look forward to the next step in the story as much as the finalization of the project with a world concert tour. We love to share your enthusiasm and despair, your aspiration and frustration, your elated victories and confounded disappointments. Look at it this way: it has been, and still is, a most glorious journey so far - why stop now? It’s all a labour of love and as long as you’re happy, we’re happy.

  • The year 2023. "We are on rebuild #37 of the MMX!"...... I think this is the strategy...It never really gets done. Only improved perpetually. In the real world this is called scope creep and has brought many a good project to its knees and onward into failure. Here in youtube land there is no such thing as scope creep or failure. Only excited supporters watching the evolution of something fascinating.

  • Martin- I've missed quite a few episodes. But, I had a thought after your Captain Context vid: Are you treating the wooden parts to reduce the impact of humidity? A couple of decades ago, we use to make our robot chassis from plywood. We did our work in Ohio but the competition was at EPCOT in Florida. To avoid the plywood swelling from absorbing water due to the high humidity, we painted the chassis with several coats. Is there a coating on your plywood parts? Maybe it won't be an issue with your smaller parts.

  • Piano Technician here, I would advise against using Graphite Powder. In pianos it is useful for the short term, but eventually it gums up. Some "technicians" use graphite so much that it ends up everywhere, and those parts need to be cleaned or replaced because the friction becomes unmanageable. Instead I would recommend using Teflon powder, very sparingly.

  • An alternative to graphite is High-Density Polyethylene (HDPE) . It's like a low-friction plastic material that should be pretty easy to machine.

  • I think your math is off. If you do something 100 times with a 99% success rate, than you have 0.99^100 = 0.366 chance of it working. Obviously not good enough, but that's still not 100% chance of one failure. A 99.99% success rate 3600 times is 69.76%. Increasing success rate by a single nine gives you 96.46%! If you want to play the machine ten times a day with a >95% success rate (less than one failure a month), you need each individual operation to have a 99.9999% success rate. Which is probably beyond standard engineering. NASA quotes figures like 99.74% success rates for engines. Have you considered finding ways to recover gracefully from a failure?

Around 2011 I took an angle grinder to the back and was cutting out redundant brackets from 1993. It was bad/good feeling. It was waaay better for it. *At the moment I am making a Mamod steam car into a Gscale rail car. I will have a small box of prototype parts that each took hours to make. :O

Watching you do this so many times is just monumentally disappointing. Keep screwing yourself, the people who help you, and your fans. Just finish the machine dude. Probability and what actually will happen can be two entirely different things. But oh well. Just milk a Patreon for years with no finished product.

  • Well your probability math is a bit poor there but okay, u can't really say u have a 99% stability rate based on 100 marbles, that is not a dynamic probability. What you are looking for is stability, meaning a 99.9% probability for each marble to go through the system successfully, if after this you can start calculating using the probability of instance 1, and put the number of attempts as a power of. Probability of a marble stopping within 3584 time(s) at 99.9% probability = 0.9993584 = 0.027714675751556 = 2.77% So at 99.9% you'd actually have a 2.77% failure rate for each time you played the song, that is more than acceptable.

  • So this is what I'm wondering... Isn't the likelihood of a master musician missing a note greater than 0.00001%? And isn't the likelihood of a string failing on a guitar greater as well? It's starting to feel like you're chasing precision that might actually be unachievable. The Lego company has some of the most accurate and precise manufacturing of any factory in the world, and 18 out of 1 000 000 pieces are faulty. That's 0.0018%, that's a lower precision than you are aiming for with the MMX. You are building a machine at least partially by hand with the goal of it having higher precision than some of the most sophisticated machines in the world. I'm worried that your unwillingness to compromise could make the completion of the MMX impossible. I admire the dedication, but this is the first time watching these videos that I've truly felt that you might be aiming towards the unachievable.
