EV3 Brick too slow...
Conchas replied to alfredone78's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This is the way it is! About 30sec to power up the Linux kernel and the same to shut down. -
Parts Unique to THIS Set Only
Conchas replied to DrJB's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
That's true but it should be possible to achieve with some SQL statements over one database like BrickLink. Then it would produce updated results as the new inventories get introduced. BrickLink already produces some weird reports, namely on 'Item Relationships' (http://www.bricklink.com/catalogRel.asp). Probably not all based queries, but some should be. -
New part on Lego Education site?
Conchas replied to DrJB's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
No! This one has two axle-holes instead of the pin-holes in 44809. I'd say it would be an improvement when compared to the former part. Maybe it is a bad Photoshop job. But on LE site, and since 2008. Weird! :P -
The "rocks" were homemade with Polyurethane and painted with a couple of spray cans (anthracite and light gray). No, my 41999 did not run outdoors before this video. 9398 did, even on the seashore... But the point is that the last section in the video was filmed with the same batteries used on 41999 before and without recharging them. So my conclusion was that the extra weight and almost surprisingly also the lights, had their effect. 41999 is still a great model though!

Today I've made available my video from 41999, performing and comparing it with 9398 in some situations. http://www.youtube....h?v=_EnLnbtbbWw

No, mine and others will be online a couple days later, as Egor deserves an exclusive for some time. :) I'll do something about the box first, then a live build session and later the rest of the review. At least this is my actual plan. For now trying to complete the review on 42009... :P

Unfortunately I've not been reading so much here lately, as the time available has been very scarce... as you eventually may have also noticed from TBs slow down. Hope to recover after my LUG annual event end of this month, which I'm one of the organizers. :P Basically I get notice on every new post here, take a look but won't return to it unless I've subscribed specific notification for some special interest. I tried to provide some assistance to this case, with already some results and hopefully TLG will provide further info soon, as we have discussed. Best!

What do you mean "like this"? It is not a Technic set, but TLG did number a limited edition of Santa Fe locomotive (10020-2). 10.000 units if I recall it right!

Hey guys, We will get an official explanation soon, by the Technic team, at the proper place. Best!

Lego 8880
Conchas replied to SNIPE's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
No! That image just explains how you should correctly align/assemble the parts in that step, to have both front and rear wheels properly aligned when not steered. -
Yeah! I'll be releasing some more goodies, as I get the time for that... :) Thanks! And congratulations for your achievement!! The Boss was not my preffered, but a very good one indeed! After the Dunechaser... I prferred the horontos Quadbike. But will buy the Boss for sure!

In the sequence of the experiments that I shown yesterday and with the advent of AR.Drone, the natural next step is exactly the quadcopter, which should solve a lot of problems by the concept itself. Although I did not pursue yet the objective as still believe in very, very limited success. This even if you have mirrored LEGO blades for the counter rotating setup, or manage to mount them in such way with the minimum parts possible. Since the goal is to make some kind of pure LEGO contraption fly, I would not consider any over-voltage setup. Then as demonstrated you will need a BB for each motor. Four of them will be too much to lift and the flight will likely be always tethered... Not to mention there is no simple way to implement the necessary rotors control with LEGO parts, like done by AR.Drone electronics. Most promising would be the usage of 6-blade rotors, but as tested also, the BB do not cope with the requirements. That said, I would dare to add, that I will prefer to play with one AR.Drone device.

I know you have not seen many MOCs of mine. Photos with Technic stuff are even more rarer... It doesn't mean that I do play with bricks and not try to build something... So you started the topic and made me to look for these... they are dated back from December 2010. After some experiments at home, this was demoed at Hispabrick event in Barcelona. Failed self powered flight attempt... Although each motor was not under over voltage conditions. On the contrary!... each one was supplied with a PF Rechargeable Box (7,2V max). It should have been less after a trip from Lisbon to Barcelona and several experiments in that day. See the near take-off moments.... Although this contraption was not prepared for sophisticated torque control, and tail rotor speed was just controlled from the BB 7-position speed control. This is raw material I had never edited and was laying in my to-do-list as many many other things... The videos are in the two links below (don't know if I can embed Flickr videos here) http://www.flickr.co...57632471896321/ http://www.flickr.co...57632471896321/ Have uploaded just these three items to my Flickr photostream. All the other stuff I have is quite repetitive as it was recorded to make a selection and prepare a more detailed video. Before this, at home, I made larger experiments with 6-blade rotors but the drag or the torque was simply too much and the RC motors always slowed down considerably in a mater of 1-2 seconds, making the experiment unviable. I think the current consumed was raising to fast and current limit protection on the PF BBs kicked-in. First ever? off board self-powered unmanned LEGO near flight...
