Hugolin

Thank you. To make it a real GBC, it's not so simple. You have to keep enough balls for all the notes to be played. The flow is above 1 balls per second, so we must add a mechanism that starts the music only when the board is full. Yes I know this fabulous machine: the idea comes from there. I can play other music, I chose this one because with 5 notes it is recognizable. And I do not have enough balls to play continuously more than that. But without this limitation, I could lengthen my MOC is playing something else.

Hello. Here is my latest creation: a Legophone. A what ???… The name is inspired by Gaston Lagaffe's Gaffophone, and like him he makes music (but does not destroy anything). More clearly, it is a mechanical xylophone (metalophone for purists). It is quite simple: pins arranged on caterpillars come to turn knob pairs. These release a ball falling on the xylophone. Voila for the operating principle. To be able to play a melody you have to go up the balls as you go, which makes the whole thing look like a gbc. Here are some photos : A general view: The inertia motor on the right of the photo has been removed for the video: too noisy. On the upper plate, there is a small black separator on the right: it is for condemned the last note: On this same plateau there are several small arms that serve to distribute the balls to ensure the feeding of each note. Unfortunately it works well only if there are enough balls, and of course I do not have enough. So I palliate this problem by playing a music that has only 5 notes (it's still limit: it would be necessary that the plate is full at the beginning) The lift system of balls: The lift is in two stages: the wheel makes it possible to recover the balls at the lowest level. Otherwise I would have had to raise all the moc. The screw is made through a pneumatic hose. Note that I did not want to motorize this system, and connect it to the crank Legophone. But between the length of the transmission and the multiplication for the screw, everything became too unstable. A more precise view of the Legophone: The xylophone blades are suspended and rest on the rope (made with my braider). The small yellow flip-flops are used to stop the knobs to prevent several balls being released. The video should be more telling than my explanations: Did you recognize the music?

I have to redo the photos I lost due to an error. I just do not have enough time for that. But I will try to do it before the end of the month.

Hello. Congratulation for the reproduction of the hexapod and the instructions. Very nice work. The problems you are experiencing are probably due to the fact that the LDD file is based on my first prototype. Many changes were made subsequently. I start building another chassis (which for lack of time does not advance much). I can make you pictures of this beginning.

Hello. Not much time for lego since this braiding ... I walk up the post to show the change of the reel of the braider. In fact it is no longer a reel but a winch. A photo of the modified part: The winch I did is like a capstan. The rope makes a turn on the "capstan" (tires) and is held in tension at the outlet, so that the friction allow towing. On the following picture the towed rope is that high, while the bottom one freely out of the mechanism. This way, no need to wait for braiding to recover the rope: We can take a piece during manufacture. On this last picture shows a jaw made of 4 12t and kept tightening by elastic. It is the latter which maintain the rope in tension, allowing the winch to tow the rope correctly. The principle is simple: the 12 t pulling slightly faster than the winch and easily ripent on the rope, which ensures the tension of the latter. Voila, I hope I was clear enough. Otherwise feel free to ask questions. A short video will surely complement the explanations.

Thank you all for your comments You're right, the limit is the length of the wires. The largest rope I can do is about 2 meters (± 2 yd). You're right again, I add it in the presentation. and here : I hope that the "WIP" video answers your question. Not yet, but probably coming soon. New Member, yes. But not the first post. Here is my first post : http://www.eurobrick...howtopic=118049 Splat => I saw your braider. I hope see the next soon.

Hello. New post in this new year to show you this: So what connection between this rope and Lego, you say? The machine that does it, of course !!! I start with the video. Edit : WIP vidéo : Now, photos and explanation. This braiding is based on the following system: to alternatively turn the trays. Although it uses 12 strands, braiding is relatively simple: The strands are braided in fact four by four. The blue plaques turn to the right and red on the left, etc .. Between each rotation, the trays are realigned by "jaws". To power, a motor M is more than enough. The lever to switch to manual. Here, the manufacture of the central party of the rope: This part can be replaced: Here two little winding mécanisme for the bobbin: A very important detail: the elastics that ensure proper tightening of the braid. Finally, different braids made by the machine: And also Happy New Year !

I realize that I have not said thank you for the frontpage. Also thank you for your comments and your welcome. Lego ideas: no. Lego can too easily refuse: it is a weapon. I start ordering parts for a second hexapod to make photo instruction. I'll do the driving part, without panel, cockpit and other. I'd surely the rest too, but again later. All this will surely take some time ...

I hope these photos meet your question: Lucky yes, but especially a lot of thought and time. First, when I rediscovered LEGO, I did not have the reflex will see the creation on the Internet (I still did not know the existence of the forum). So I had no preconceived ideas when I thought about doing a hexapod. The first thing that came to my mind is the distance traveled by the right and left legs in a turn is not the same. The first hexapod was based solely on this principle to vary the amplitude of the legs. Here it is : For rotation better, the trajectory of the legs must be a curve and not a line. Second hexapod with the chassis that this curve in addition to the amplitude modulation: New version with motorized armament. We begin to see the shape appear on the last: The penultimate done to competition on the TechLug forum. The principle remains the same, but the mechanics changed a lot. A servomotor control the pivot points and the curvature of the frame. The mechanics of the latter is strongly inspired by that: In short, walking tank did not happen by chance. I will try to make a manual, at least in picture. But I never made, so it will take a long time.

Thank you

Thank you again for your comment. Yes, the mechanism changing the amplitude is sufficient, but the turning radius is small without bending the body. The first hexapod I did rediscovering LEGO worked like that. The curvature of the frame came after. I can not easily change my OMC, so I made today a small hexapod that uses only the amplitude variation to turn. Here's the video.

Thank you for your compliments. I do not have pictures without the panels, I would do when I have time. I'll probably make a second copy of the hexapod. I would make more detailed pictures under construction chassis. Meanwhile, I am still this video (only the legs are covered). On the front we can see the gray parts (which hold the pivot point) move up or down depending on the curvature of the chassis:

Hello, Here is my latest MOC, a hexapod: I will not get into great explanation on how it works: my English does not allow me. The operating principle of the walker is as follows: - The legs are always synchronized. They are actuated by a motor L. - Their amplitude varies depending on the curvature of the frame: in bends, the legs of the left and those on the right course is not the same distance. Curvature is ordered by a servomotor. The tabs are actuated by connecting rods and slide in pivot points. To change the amplitude, simply varying the pivot point height Photos : Functions: guns and motorized cockpit (2 motor M): Here is a little animation to see their kinematic: Finally, the video: Thanks for reading. :)

Hello, I call Hugues, 41 years old and still not an adult (even if having two children compels me). I am French and my English is very limited. The nickname "Hugolin" comes from the time when I was diving instructor, another of my passions. I re-discovered the Lego technic few years ago. They have evolved a lot since my tender years, but I'm quickly recovered. Possibility that with these new parts ... Some examples of my creations: See you soon on the forum.
