Berthil

It happens, especially when you make/remove steps in between. All building steps should be defined before making the page layout. The only remedy is a backup (which I always make after I worked on instructions) or put in the hours again. And welcome.

Thank you all! The free building instructions are up: https://rebrickable.com/mocs/MOC-165470/Berthil/excaliburburg/

My first post here as it is my first Historic build. This is a remake of 70840 Welcome to Apocalypseburg into a Castle theme for a LUG competition (LowLUG, Dutch). After the dust of medieval wars has settled, all that remained were the King Arthur’s Lion Knights and the momument they had build out of the ruins. Excalibur, King Arthur’s tomb, armory shop, blacksmith, torture room, pig farm, watch tower, archery shooting range and hidden real Excalibur is what is left. The old Kings carriage now serves as a chicken run. King Arthur has all of his fingers, Lady Liberty was missing some. An elevator moves up and down Excalibur, the target in the shooting range moves forward and backward. The watch tower and Kings tomb are removable. Video with more details: I have created free building instruction for these 6000 parts, enjoy! https://rebrickable.com/mocs/MOC-165470/Berthil/excaliburburg/

Why don't you create a Bricklink wanted list from your Stud.io file with the build-in 'add to Wanted-List' function and download the XML from Bricklink?

A very good initiative to let the community build such a digital design database of official models under the assumption it will be a free service. I've used a few digital design available here in the Eurobricks thread, a more extensive, structured and up-to-date website would be very good.

Good luck with that list when converting large designs. LDD is pretty much dead right? It still works and relies on volunteers who make 'custom' parts packs and/or LDraw database is used but other than dead LDD itself has no updates since many years. If I'm wrong I apologize. Might as well start with Stud.io which translates one on one to Bricklink (both owned by TLG). It imports LDD files but many require work after that. Next to that use the SKU number (Stock Keeping Unit) or ID number, it holds color and part and can't go wrong with that on Bricklink and TLG Pick a Brick

Thanks all! Actually I was already busy with the loop idea in a GBC before the 10303 was developed and sold. As I wanted to keep all tracks LBG I didn't want to use the loop pieces from 10303 but would have been much easier to use these. The sideways technique can been seen in other rollercoasters with a loop, especially rollercoaster before the 10303 was sold. I haven't seen it in a GBC. It was a gamble if everything would run smooth enough without having to go very high with the spiral but it worked out well.

First post updated with a fully mechanical Rollercoaster GBC. Happy with the final result as It took a few designs because there is a lot of variation in how the Carts behave. Turning a discontinuous variation into a continuous process was not easy.

In Pybricks I use the run_untill_stalled command to calibrate. Store motor angle/rotations on either end and keep track of them or reset the angle and don't go past it. Pybricks uses Python so may translate one on one to your Raspberry, not sure if your Raspberry would need the Pybricks firmware installed on the hubs. Pybricks has example projects and commands documented and it should be possible to operate the crane with Pybricks firmware and standard PU remote only (no devices).

If you have the CSV parts list from Stud.io (or Bricklink XML via Bricklink wanted list) you can create a parts list on Rebrickable from it. This parts list can be exported to a HTML table or HTML Grid with correct images. I haven't tried but the HTML should be saved as an HTML page and import in Excel or even copied from the clipboard to Excel. Custom parts are custom parts or parts not available so need to be handled seperately as neither Bricklink or Rebrickable will recognize them. Could be that Rebrickable will show the correct part color even if not available. Sound like you are making a MOC to sell to a Brick cloning company that has all colors, otherwise it would make no sense to have parts in a parts list if not available. If my advise is of use to you, remember me when you make your first million please.

I would welcome a Model Team contest, this is the 'LEGO Technic, Mindstorms, Model Team and Scale Modeling' forum. Technic we had a lot, Mindstorms has been discontinued, Model Team and Scale Modeling with a good combination of Technic and System remains.

Jury categories are clear at the start but as a builder you can deviate from that to have more fun building because you like more what you make. The reward for a having fun can come afterwards when public voting choses their categories they find important and if they are the same as your fun categories, you will move up the order depending on the jury/public voting ratio (preferably set at the start). Sticking 100% to the top categories might bring you glory but could be less fun as you are building in categories you find less challenging and fun. Models might also look alike a lot. You want the last and I want the first so don't tell me I don't get it. In the latest competition there was no public voting and I have the feeling there won't be in the future. There was also not much transparency in the jury voting. With the category system we can have transparency upfront and public voting without much extra effort and keep having fun. I guess it would be possible to replace the category voting by your 'awesomeness' voting for every model. But when 50 models, this would be a lot of work for public voters or we go to the previous system where they can pick their top 5 or top 10. In the category system they would only have to rate categories once and the result is tied to the jury voting. I'm not participating in the discussion anymore as I have made my point. I will wait what the next contest will bring, it is not in our hands but in the hands of Jim and Jury.

Probably also a misunderstanding. The contest categories are fixed by the jury at the start of the contest and not the end. Probably as it is now but a bit more detailed via the categories. Public voting would be in those categories and how many points is set by the jury per model and category after closure of the contest. So the categories are known upfront but of course how many points per model per category after the models are finished. Even a third multiplier could be introduced by category order of the contest (preferably defined at the start). With the three multipliers there should be enough point differentiation along the predefined contest categories. Let me do a full scenario for a contest with three distinctive categories and three model entries to keep it simple, because I feel I'm not good at explaining the system. TC26 Technic Powerboat Contest with categories in order of jury importance (multiplier in brackets): Jury Categories: Speed on water (3) Maneuverability on water (2) Looks (1) It is clear at the start of the contest that the jury is looking for fast models that turn well, looks are less important. So you shouldn't make a Technic Titanic that looks great but is slow and can't turn if you want to win by jury. Of course if that is what you want to make to have fun it is no problem, you can make what you like. End of contest and models A, B and C are finished; Model A, moderate speed, high maneuverability, looks are okay Model B, clearly highest speed, maneuverability acceptable, looks totally absent Model C, low speed, moderate maneuverability, looks 10 out of 10 with a mini Technic Titanic. 4 jury members score 1 to 10 in the categories for the three models using their own interpretation. This could mean one jury could give model B 10 points for speed but the other jury 9 points because that jury thinks it is still not fast enough. I created the above matrix in an Excel with the three models, three categories and 4 fictional jury votes from 1 to 10 for each model in each category. I won't bother you with the details but each jury vote fluctuaties between the categories because of personal preference and interpretation. The jury totals for each model and category are (where list number is category); A=22 , B=39, C=3 A=39, B=16, C=16 A=18, B=1, C=40 Totals for each model; A=79, B=56, C=59 WITHOUT the category multiplier Model A wins, Model C 2nd, Model B third. This was probably the jury voting method in the last contest But now we multiply with category multiplier in this simple example, probably we would have 10 categories in a real contest. Calculation could stop here and end of contest. multiplier 3; A=66, B=117, C=9 multiplier 2; A=16, B=32, C=32 multiplier 1; A=18, B=1, C=40 Totals for each model; A=162, B=150, C=81 (looks has multiplier 1 which is no multiplier, probably avoid category with multiplier 1). WITH multiplier Model B moved to 2nd place because speed has highest multiplier as it was most important in the competition, but not enough to win from model A which had the best mix of speed and maneuverability. Voting could stop here and this would be the end result without public voting. Now it gets interesting, public voting was in parallel with jury voting so model order was not known and also doesn't matter and each voter rates the categories they find important. We have 5 voters with category number and score between 1 and 10. They look at the overal competition with all entries and decide what they find important, list number is the voter voter finds straight line speed very important because voter is a drag racer; 1=10, 2=1, 3=6 voter is a creative designer and find looks very important; 1=4, 2=3, 3=10 voter looks at technical solutions and knows maneuverability in water is hardest to achieve but also finds looks important; 1=2; 2=10, 3=8 voter just agrees with the jury and should be rated accordingly; 1=10; 2=9, 3=8 voter finds everything technical not important and just looks at how it looks; 1=1; 2=1; 3=10 These category votes can be used as percentage or multiplier on jury votes with or without the jury category multiplier. If jury wants more effect on the outcome take scores with jury category multiplier. In this example I will take voter percentage of each jury category vote without jury multiplier for each model where 10 points is 100%, 9 points is 90% etc. So model A had 22 jury points for speed, voter 1 has 10 points for speed meaning voter 1 awards 100% of jury votes to speed meaning 22 points for model A. Model C had 40 points for looks and voter 4 has an 8 for looks so Model C gets 80% of 40 points = 32 points. Etcetera for all voter categorie percentages and models. Outcome after public voting where list number is voter with model total according to category voting (because of percentage we are getting decimals now); A=36.7, B=41.2, C=28.6 A=38.5, B=21.4, C=46.0 A=57.8, B=24.6, C=48.6 A=71.5, B=54.2, C=49.4 A=24.1, B=6.5, C=41.9 Totals (rounded): A= 229, B=148, C=215 So after public voting Model C has moved to 2nd place because there were voters that found looks important. Still model A is 1st. Now add jury votes to public votes, again this can be done with multiplied jury votes or not. Without jury multiplier order is A-C-B, with jury multiplier it is still A-B-C with a very close tie between B and C. Contest organizer and/or jury can decide to use different multipliers, or even a jury/public voting ratio, but voting system would be the same. I created an Excel that did all the calculations and most of the time was typing this, the Excel was quickly created. In the end there would be categories with a multiplier rating by jury, jury category voting per model and category, public voting per category and an Excel that brings it all together including decisions on multipliers and jury/public voting ratio.

I wanted to keep it less work for the jury by proposing a winner by jury in each category but it would indeed be better if the jury would score each entry for each category like you propose. With a multiplying factor all public votes can be applied to all entry categories resulting in applying 100% voting for all entries in all categories with jury voting for all entries as guidance by jury multiplying factor. So if a model gets 10 in a creativity category through jury voting this is multiplied by public voting for creativity. So when one public vote has 8 points for creativity, voter would hand out eighty points to that entry in creativity category. This can be applied to all entries and all categories and all votes and jury only has to vote all (self defined) categories for all entries and voters will only give their category vote. I don't think there will be many entries with the same amount of points in this system, of course with enough voters. But since voters do not have to look at every entry in detail (the jury does), and everybody knows the categories they like (and don't need to tweak a lot for every contest), I hope there will be more voters than usual. Everybody happy, may be even you. If not clear I could work out a tangible contest example in more detail. If nobody is interested I save myself the work and await the next contest.

If I remember well 500 pages was mentioned by someone else so I'm not extrapolating, I'm downsizing. I never said you want a 100 page lawyer document
