  1. Since I have more money than sense I've been collecting cheap round bricks for some time. Partly for building trees, but also so I have something for excavators to dig in. But looking at the BWE, I think it's going to need quite a lot of re-engineering to be capable of digging while slewing. I suspect at least one XL motor one the end of a shaft made of 2x2 round bricks, or hopefully a 32 axle, then geared down a chunk at the drive connection. But I've shifted from being on the fence about this model to being quite keen to get one now that I've seen Sariel's review. In many ways it's my ideal model - a giant parts pack with a decent number of a new, useful part. And only one motor, of a type I only have a couple of (I bought several 8043's for the motors a few years ago when they were cheap... cheaper than BL'ing the electric bits).

    Air Boat

    That's really impressive. The combo of finally a decent propeller and the high speed motors is genius. I like that you have a decent steering angle too, so you can get the maneuverability.
  3. with point 12: always on, I am less of a fan of that. The gap between a couple of microamps to keep the switch sensing circuit alive, and a few milliamps to keep the BLE module listening is often significant. I have some SeeSense lights that do this, and they run flat in a week or so if I don't use them or charge them. Admittedly the battery is much smaller, but it's worth keeping in mind that people will not be using every BuWizz they own, every day or every week. Quite likely a lot of them will end up in the back of a box somewhere for months at a time, to be pulled out when a model is finished. It would be annoying to have to charge them before being able to connect at all. I'd rather have six months life and a button than one month and not have to go to the enormous effort of pushing the button. A "24 hours then it goes to sleep" mode might make the "deep inside my MOC" people happy, or make it yet another user setting :)
  4. That's pretty impressive. I've always struggle with trolley rope tension and your solution is nicely elegant. And the half width liftarms make it all quite compact too.

    Longer Studless Beams

    Yes, but it's much easier to cut half a stud worth off the end of an axle than to join beams together. I've done that just to get black axles in whole number lengths cheaper than I can buy them, and I suspect that's going to become even more necessary now that colour vomit has infected axles.
  6. I didn't even realise they'd been bought out. Any idea when TLG is going to integrate them with the main Lego line?
  7. It looks interesting, seems you traded speed for traction? And a lot of the effort is getting the code to work, based on the number of fails I saw :) I can't find it on YouTube, but there's this and a
  8. And most tracked cranes and excavators use hydraulic motors the same way. Mining trucks are usually diesel-electric like trains. Doesn't stop Lego from putting shaft drive setups in them. I agree it would be odd, but less odd than if Lego built a model diesel-electric system. What they could do is a set of wider curves, which I reckon the train guys would love, but make them so they stack next to the existing ones. That would give us three gauge options and really open up what you can do with train models. Well, that and some 6-10 stud high train wheels :) Something like that would mean you could use the inside or outside of each pair of tracks to get a slightly wide gauge, or the inside of the inner one + outside of outer one for really wide gauge. With current parts that would be ~10cm I think, or 12-15 studs. Wide enough for some really detailed models!
  9. I keep thinking about where the money comes from. With Star Wars there's a big fan community of geeky types who will also buy Lego. With Technic we're seeing a lot of cross-marketing as TLG build sets that will sell to overgrown man-children with money, branded "big boys toys". So the obvious step is to first look for a market like that, then work out how TLG could sell to it. Think broad and sub-$US1000, not super-yachts. So some kind of music maker might work, but it would want to be a copy of Brian May's guitar or a Daft Punk helmet. Maybe an animatronic Freddy Mercury? I do wonder whether a larger scale railway might work - maybe take the Duplo track width but run on the top edge of the sections rather than in the grooves, add some more features, build trains that run on it and start with a Model Team/Technic ultra-detailed locomotive, but also build something like a remote controlled crane carriage, or a container loading setup. That might work in the "new theme" sense because they could obviously just keep adding new stuff, and could tie in with people like Maersk or whatever. Another option is dinosaurs. Sure, they're usually a fascination for the 5-10 year olds, and the walk rather than roll, but animated dinosaurs would be cool. It's something that could be done without programming/Mindstorms, and I suspect very few new parts would be needed to make a couple of walking chassis 20-40cm high, and with the plethora of plates and panels available now skinning them wouldn't be too hard. The big issue is colours - bright orange or yellow dinosaurs are going to look very weird. But Lego doesn't really do a lot of shades of green and brown (especially in Technic!)
  10. I'm with the people who would like to see a return to functional models. Even the really early "big car" models had more functionality than the UTC, and they had hardly any parts to use to actually build the model with. Compared to something like the 8880 the Porsche is more like "ultimate model team" than Technic. I hope the designers can surprise us all, like with the bucket wheel. A cable car or a working boat, or a mechanically programmed cookie decorating machine. Even a new rail gauge, which might sell in giant piles to all the train people, super-accurate model people *and* the modelteam/technic people. I dunno, I'm kind of "anything but yet another car". I realise they don't sell, but that's what I want :)
  11. Yeah, I'm all for locking them. It was funny once. What's to stop anyone else creating a mess of similar junk, encouraged by the moderators saying "if you don't like it, don't look at it". It would quickly turn this sub-forum into a mess of hundreds of "threads" as people competed to post the longest shaggy dog story or whatever... told with Technic to make it on topic. Can we at least try to keep the sub-forum usable to people who don't have the "hide this thread" and "hide all from this poster" plug-ins?
  12. I have done this in the past just by linking the steered trailer wheels to the angle between the bogie and the trailer body. In the crudest case, a pin down from the trailer body attached to a leading steering arm will turn the bogie in the direction the trailer is turning, but with the lag you want. I used something a little more controllable but that is the basic idea.
  13. I've been thinking about rebuilding my quad bike with MTB fat tyre wheels so it performs better off road, but yesterday I was looking at pics from a friend who's been riding around Australia on a DIY solar power assisted trike. He's just switched to a fat tyre MTB with a trailer carrying the panels. So I started redesigning the quad in my head, from scratch, to have two suspended live axles, big wheels and a bigger but lighter bin on the back (current one is rotomolded plastic and is 12kg with the lid). Then I thought I'd better see whether the ideas worked at all, so I made a Lego "sketch". (website) I've used beams to get lateral stability rather than panhard rods, because for a bicycle-based design that makes more sense. You can see where I fitted a panhard on the front, though. Live axles rather than independent suspension because I have a rigid rear axle on my current quad that I will move across, and it's easier to make the parts in my workshop. handlebars come straight up off the front axles because it's mechanically simpler than a series of linkages to bars on the main frame (my current quad does this). Total build time about an hour :) This is more me thinking out loud than a proper MOC at this stage. I just wanted to see whether the idea would work.
  14. Sorry, I meant 7 long, should have looked it up. 7 long... 15 under $1 each, then $2.36 each and climbing. But I note I can get black axle with stop now, which is nice. And the axle pin part that's usually blue is widely available in black. Provided you're willing to pay more than $1 each, or $2 if you want more than 100 of them. {cough}
  15. This. It seems to be getting worse, they appear to be going to red and yellow axles to fix the "is that grey or black" problem. I pay quite ridiculous prices for some rare parts because I am not a fan of the blue pins, but there are now so many that are never made in black, and there is no colour that they're all available in. Fortunately I think I have enough 3 long pin friction in black now. I also gave up a while ago and bought a pile of 12L axles and cut them into 5/7 and 3/9 lengths, because 5 long black axles sell for silly money but 7 and 9 long just don't exist. At least with axles I *can* cut them down. But if TLG did decide to offer "parts packs" of black pins I would be thrilled. Expensively thrilled, but thrilled. Just sell me these parts in black in bags of 1000 already :)
