    Instead of the small pump, you can use the small cylinder (leaving one of its outlets unused), since, during its extend-compress cycle, it will both push and pull air.

    Thank you all! As you may have noticed, I don't post here much (my free time is very short and I have to spread among all the LEGO stuff I do), but I usually lurk around here in the Technic section. While I get acquainted with the LAmb (I use this designation to distinguish from LA ) environment, feel free to post your requests/concerns/whatever to CopMike on EB or me on TBs. And, since Conchas defamed me as a "cat lover" and about 2/3 of comments for one of the review videos I filmed appeared to like the cat better than the helicopter, here he is again. Cheers, Alexandre

    I've been asked to forward the requests on this thread to the LEGO Ambassador forums, as well as a direct suggestion via e-mail, which I'm adding here to keep everything together. The suggestion is, just like there is the Technic beam 3x3 T-Shape, Benjamin Eberhard suggested similar, cross-shaped and H-shaped 3x3 beams. I made and attached here some crude mockups of the ideas.

    I have one! (a question, not an EV3) Just as there's an instructions app for iPad, will there be one for Android tablets too?

    Well, Meccano and Fischertechnik can be considered competition... but I very rarely see the former, and never ever the latter, on Portuguese shops.
  6. AVCampos
    Wow! Well, I guess it only a matter of time... Since they're more complex, I'd guess Chinese PF imitations will be worse imitations than standard beams and gears.

    Ah yes, it now worked. Although I had to run the command prompt as administrator, or else REGSVR32 wouldn't work. Thanks! Now, to find a way to enable alpha transparency and radiosity on POV-Ray 3.7 (it worked fine on 3.6, but I want to take advantage of 3.7's multicore capability)...

    It's 1.9, from the link on the first message on your link. The app itself (old version) installed well, then I copied the contents of the 1.9 zip over it to replace the executable.

    I bought last week a new laptop running Windows 8, and yesterday I was installing the LDraw tools in it. Everything appears to be working well (except LDView's auto part downloader; that must be due to folder permissions), but I can't run L3PAO. it says that SYSINFO.OCX is missing or invalid. I downloaded it from its site, then applied the beta update from here, and tried putting the two required OCX's both on the program folder, Windows\System32, and Windows\SysWOW64, with and without rebooting, and without success. Does anyone have a solution? Thanks in advance!

    The 8421 came out 8 years ago. LEGO Technic has evolved a lot since then, and also there's is a whole lot of builders who didn't have access to it at the time. IMO a flagship crane truck for 2013 is completely reasonable.

    If I were a betting person, I'd bet that the 42008 indeed has pneumatics. Even if not, it's still a great parts pack for the unusual green colour! Also, judging by the green panels on the sides topped by red micro panels in a "staircase" pattern, I'd say this set will rely heavily on stickers for colour harmonising.

    Actually, that's exactly how the PicooZ TandemZ works: its two rotors spin in the same direction, with one of them slightly tilted sideways.

    I can't wait to watch that video (it's inconvenient to do that at work)! As for a Chinook-like all-LEGO helicopter, at least with the same configuration (two three-bladed rotors), I can say it's not possible. I tried a few weeks ago a three-bladed rotor made with 9396 blades, connected to an RC motor and powered by a train regulator (10 V), and it gave nothing more than a gentle breeze... When I have time, I'll try to figure out a design capable of securely holding 6 blades and with a more aggressive pitch.
  14. AVCampos
    Wow, the helicopter thread has become an airplane thread... Anyway, I tried a few moments ago a rotor I designed with three 9396 blades angled at about 14.5º, connected to an RC motor powered from a 9V train regulator. In a word: disappointing. At least it showed that I can push the setup a little bit further without triggering the regulator's over-current protection. I'll try adding more blades and angling them more aggressively. If only the blades weren't so expensive!

    I think the increase in ground speed wouldn't compensate for the increased complexity, weight and geartrain friction when flying.
  16. AVCampos
    That's easy, everybody does that, wether they want it or not.
  17. AVCampos
    I Also thought about the issue of number of rotor blades. What other factors are to be taken into consideration when choosing the number? It mustn't be predefined, or else all helicopters would have the same number of blades...
  18. AVCampos
    Don't forget that the first time we saw that ball receptacle, it had a drive shaft running through it... so, you should be able to insert an axle from the other side and push the ball out.
  19. AVCampos
    I don't think so. The EV3 has a small USB port near the motor ports, probably a client port for connecting to a computer, just like the NXT, and another one at the side, probably a host port for the WiFi dongle. An EV3's host port could connect to the next one's client port. [edit] Also, the different number of ports and motors in a set isn't new: the first Control Centre and the three RIS versions had three ports and came with two motors.
  20. AVCampos
    I read from several sources that the daisy-chaining feature is incompatible with the NXT. But, since both have Bluetooth, maybe wireless chaining, like we could already do between NXT's, can be done instead?
  21. AVCampos
    I was thinking of doing exactly that, a quadcopter, come time ago, but never took off (pun intended) from the project stage... Before doing that, you might want to try building a tandem helicopter like a Chinook, as the structure connecting the motors can be smaller and therefore lighter.

    Actually, the first version did have a remote control, albeit bought separately: http://www.bricklink.com/catalogItem.asp?P=x124

    Congratulations to all those who have already reached the finals! Whatever model wins, I hope it brings new combinations of part/colour, but not exotic colours for which there is little quantity of other parts to MOC with! For example, for me blue, green and orange are great; medium blue, dark green and tan not so much. Oh, and speaking of part/colour combos, this is an opportunity to help Jennifer Clark:

    Happy New Year, hunams! *Enjoy the sauce*! I saw on the other day what they are: they're handlebars, the version to fit Friends' hands.
  25. AVCampos
    Thanks Jennifer and Eric! Even though I'm more of a MOC maker than a set collector (I buy sets for their mix of parts and to absorb some of the techniques used), from what I read these instructions are well worth on their own, even without building the model itself. I see myself reading them for the background on the machinery and getting ideas from the techniques. I think that, just like I hinted at my girlfriend to receive Sariel's book for Christmas, I may try pitching the idea of these instructions to her and my parents. I suppose there are printing services to print and bind books from document files, right?
