  1. I've amassed a large number of technic parts over the years. But still, every now and then I find myself in need of large numbers of specific parts. While shopping on Bricklink lately, I've noticed that there is a smaller/shrinking selection of these connectors, especially in other colors than monochromatic (white/black/gray) These connectors are rather unique in providing multiple options for connection angles. Yet, with the advent of panels we see less and less of them. I personally never liked too much the 'paneled' looks of recent Technic sets, but it did not bother me much. If however such panels come at the expense of connectors, then ... ? Should technic revert to the 8448 style? Not necessarily, but a balanced look where both panels and connectors 'co-exist' would be an ideal balance, as in the 'other' red car 8070. Some Statistics to illustrate the point: Number of Connectors / Total Parts / % 8448: 98 / 1437 / 6.8% 8070: 42 / 1281 / 3.28 % Porsche: 56 / 2704 / 2.07 %
  2. Agreed. They did some 'parts pack' in the past, but I have not seen any lately. The only set (I felt) was intended to 'replenish' the supply of red parts was the customized truck 42029. There, we got (few) connectors, frames, panels, suspension parts .... a MOCer dream come true. I hope they do read/monitor these threads and help us out.
  3. Yes, I just finished it in LDD and it was not fun. Primarily the colors, then few errors throughout the instructions, like in the top views on pages 9 and 14.
  4. I know what you mean. I have only 4 of such part (in yellow). Too few to build anything useful, too precious to give away :(
  5. I once got two 13 gallons tubs, full of Bionicle ... for $30 both. Lots of Technic parts, but also many useless (to me) bionicle soft plastic. Still, it was worth it.
  6. Very nice. I see many orange panels ... How many Porsche have you sacrificied recycled to build this truck?
  7. Agree fully, this is really addictive. Reminds me of when fractal and self-similar geometries started coming out ... Keep at it!
  8. On some construction machines, the bucket 'opens from the back' with hydraulics. I'm guessing for the BCE, some mechanism does the same function.
  9. Anyone tried to build these in real life, besides the OP ?
  10. A bucky ball (truncated icosahedron) is possible with these two parts. However, you can build it in real life (by slightly bending/forcing parts) but LDD won't let you. + or, alternatively + You'd need many parts. I have both built and displayed at home. I'll try to remember to take photos tonight. There are other ways to do build the bucky ball with system (non-technic) parts The one I find rather 'unique', is done by Hero Factory parts, and I believe an LXF file is available
  11. If we look closely at many of the technic connectors, these are made of only four possible 'elements': 1. Male pin (friction or smooth, does not matter) 2. Female pin 3. Male axle 4. Axle hole (old bushing) Then, each of the available connectors (below) is essentially a combination of the above 4 sub-elements stacked next to one another, and with 3 relative orientations/rotations. With such 'basic' framework, What parts are 'missing' i.e., not in the current lego assortment? We have some recent connectors recently, but there are few still missing. For example, all connectors shown below fall into such group made-up only of male/female pins and axles Incidentally, all lift-arms (thick, not thin) are series of female pins and sometimes axle holes, all stacked next to one another. Some connectors that do NOT fit in this scheme are those that have half-width beams and those at angles
  12. I'm not sure. Most lego parts have one plane of symmetry (except for worm gears). The basic 'primitive' in this discussion (the many examples shown) needs to be 'not-symmetric'. In 2D space, it might be possible, but in 3D ... not so sure.
  13. Many of the contraptions on here remind me of the various Mathematica solids ...
  14. Thank you. The various projections shown in prior posts 'suggest' that the rows (of same color) are placed at the corners of a square, when in fact those rows are both at the corners and centers of such square grid. Which is what I meant by a 'grid twice as dense'. Also, my construction is likely to be more 'monochromatic' than yours as the most parts I have are white/gray/black ... time for bricklink.
  15. I tried to build this with physical parts and I can tell you this. Putting this together is much more difficult in real life than it is in LDD. Can you show only a single layer? It seems the construction I ended up with is twice as dense ...
  16. The amount of detail is mind boggling , even the gas tank lid. Nicely done! Aren't those silver rims rare? I saw them only once, on the Power Puller.
  17. Congratulations @Milan ... all the best with the new responsibility. Jim 'annoying' ??? Never heard such non-sense :)
  18. Beautifully done, Thank You!. So, of all the 24 possible combinations/geometries, 13 do exist (green), and the other 11 (red) are not really that 'interesting' or needed (at least not yet). Next Challenge: 3×1×1 ... there will be many more cases here.
  19. I thought that as well, but upon further examination, it is not. Graphite has 2 'distinct' layers. The lego structure has 3 distinct layers.
  20. The structure of diamond is a cube inside an octahedron, inside another cube ... Not sure there are lego elements suitable for this, but definitely worth a try. This reminds me of a cuusoo proposal few years back where the author wanted 'basic' elements to do chemical molecules.
  21. Thinking a bit more about your proposal ... YES, you can use the above structure to create an infinite staggering. ALl you need is to build several 'sheets' like the above and then connect them with the pin-axle (below). If we then accept that the structure needs not be 'identical' in all 3 directions, then the smallest primitive consists of one each of these parts
  22. Yes, what parts are NOT available, and do we really need them? Of course, the 'mathematical' description ensures we do not miss any combination.
  23. This is becoming very interesting. Let's look at the original 'design' from OP. 1. It uses the same parts', oriented along the 3 directions of an XYZ space 2. All combined together, the parts have In total, the parts have 12 pinholes and 12 pims. Some are already mated/connected but three of each are left not connected so they mate with the next 'module'. The above says that whatever combination f parts we pick, the total number of male/female mating connections must match (can anyone prove the oposite?) Perhaps the 'logical' candidates are to include these parts, though I have not figured out a way yet to interconnect them and some parts with male pins Whatever collection of parts we pick, one (at least) has to have 3 connection points. A part with 2 connection points can only lead to 'chains' (1-dimensional periodic structure). This rules out the secpnd part (by itself) but it could still be used in conjunction with other. Yes I know, I do not have an answer ... yet.
  24. I thought of that as well, but the OP mentioned it had to be 3D ... the above is rather 'flat'. :) PS. I've been 'collecting' the above shapes for a while, they open up many possibilities in 'geometric' design.
  25. If I may, I think using the chain links 'complicates' seriously the design. How about a chain made up of BWE buckets, and 5M liftarms on both sidee. It's narrow but would require some 'positive' means to move.
