You're fast and right... It has become a little less rare though. It is available in a couple of minifigure bags I think. I have uploaded a LDD file to bricksafe to show the mechanism. I use a slightly different setup, but the basic mechanism is the same. The two bionicle teeth that mesh with the knobgear must be pretensioned with some elastic bands. You can fiddle around with the strength to get optimal performance. Also I used these: inside the driving rings for a smoother operation. Here is the link to the file: http://www.bricksafe.com/files/JeroenOttens/gear_selector.lxf Have fun with it. -
Hi, I have found a solution for the gearbox. Not only does it work with half empty batteries, it is also 100% reliable (as far as you can test a 100% reliability) and it allows for switching both up and down (my previous versions only switched up. I have made a video of it in action (it is hosted on flickr, so I think I can't embed the video, if anyone knows how link a video from flickr let me know): https://flic.kr/p/qQq3FW Bonus question: Which part is used to connect the knobwheels to the 6L links ?

Clean design, good colour choice, well executed. I agree with the wheel placement, a little further to front will make it look better I think

Whoaa, that is brutal. I'm really looking forward to more WIP pictures . You still have a lot of ground to cover... Definetely going to follow this one

Hi, Thanks for all the replies and suggestions. I have been busy this morning incorporating all (but one Jim ) suggestions. I have designed new doors (see the end of the post) I woke up this morning thinking exactly the same thing. Somehow I must have been subconsciously been reading your post while I was sleeping : I tinkered a bit and came up with this: I'm still not sold on the white. Others suggested grey and black, that is probably better, but unfortunately those skeleton arms are only available in white. A picture of the back: Done Final pictures for today 3/4 view + topview:

Hi, Here is an update of my Alfa Romeo: I improved the gearbox selector. It now has a 90% succesrate (but only with full batteries ). I also changed the bonnet. It is more closed now (sorry about the quality of the photos, no natural light available at night ): Let me know what you think about it. Is it an improvement over the old bonnet, or is it not? I have also been trying out some brickbuild wheelcaps (Stefan's Lambo inspired me to try again). This is the best one I have come up with so far, but I'm not convinced yet that it is an improvement over not having anything). Comments are appreciated as well:
-
Very smooth lines +1 for the 'spokes'. I suppose it is possible to replace the pneumatic tubing by yellow soft axles, right? What are the black pieces in the rear window? I like it a lot. A real supercar.
-
Black beauty :) Very well executed and as said by others: perfect blend between technic and MT
-
Great display It really makes your model shine. A perfect case of 1+1 equals more than 2

[MOC] Ol'Tractor
Jeroen Ottens replied to HorcikDesigns's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Not bad for an evening of work... It has a certain quirky charm. Although I wouldn't dare to drive one without a rollcage What are the functions it has? -
This is looking very promising. Anticipating some great bodywork to finish it off...
-
I know it's a little off and I just can't get my finger on it what is causing it :(
-
Slick... Beautiful lines

Hi, Thanks for all the great reactions. It's a really nice way to start the new year for me . @ Auranapse: The spider has a different design of the frontlights than the 4C, but even then the canopy part is a bit too big. Ideally I should use stickers to cover up a bit of the transparent part. That's new territory for me though... At the end of the post is a photo of the front. @ Alasdair: you are right. Here I am afraid stickers is again the answer. Apart from using flexaxles I have not thought of a way to get that curve in the door. I also wanted to have that airintake really visible, which made it necessary to tilt the upper part of the door which gives it that break. Then again, I might wake up one morning with a good solution... @dhc6twinotter: The model has ~2000 parts, less than 1.5% of them are white beams... Don't let this post prevent you from entering the competition! As I wrote I am not sure yet whether I will enter since my gearbox isn't working. I want to have a working solution before I enter and it is not a trivial problem to solve... @Epic technic: The V4 was a compromise between realism and real estate. It is pretty tight below the bonnet and a V4 is smaller than a inline 4 cilinder. Double wishbone front: check Multi link rear suspension: I have been looking for what kind of suspension is used in the 4C, but I couldn't find anything useful. Do you have some more information on what the real rear suspension looks like? Some pictures would be great... And another photo (this is my least favorite view, too many holes in the bonnet, so I'll probably will redesign this part, but I haven't found a better solution yet): So thanks again for all the positive feedback and keep on building.

Both the dumptruck and the hooklift truck are great models. Well done. Look forward to new creations in the new year

Hi, Here is my latest MOC (still WIP). It is the Alfa Romeo 4C spider and is the first supercar that I built since I came back from my dark ages. It has the following features: Motorized (using a large BB): - drive (L-motor) + V4 fake engine - steer (servo) - select gear (M-motor) - seats (L-motor) With the gear selector you can select between 1st, 2nd, 3rd and 4th gear. At the same time you also select one of the four seat functions (seat forward/backward and tilt of the back of the seat). These functions are driven by the second L-motor and all have a clutch to prevent motor stalling. It features full indepedent suspension (double wishbone at the front and McPherson at the back) The steering has Ackermann, kingpin inclination and caster angle. All doors are openable, hood & trunk as well. The model is quite stiff, you can lift it by the handlebar without any issue. In fact the center of gravity is right below the handlebar, so it is even very convenient to lift the model that way. I was building this already for some time when the TC6 came along and since this model fits all the requirements I may decide to enter. However it is not working perfect yet The gear selector has a 10% succesrate, so that will require some tinkering. Furthermore the red wheelhubs should be white, but I am not prepared to pay 10$ a piece for them. Especially since they will become available in white within a few months. All the other white soft axles are 12L. And for the ones with attention with detail: the right headlight is at a wrong angle, that is because the piece was bent. I am hoping LEGO can provide a replacement for that one. Since this is the first MOC in a long time where styling is actually a big part of the package I would like to invite you to give feedback on that aspect in particular. Enough talking for now, here is a photo (more will follow later, but I'd first like to sort out my gearselector issue): And the best wishes for the new year of course

Nifty little model The cab is a bit hidden between all the black, maybe it looks better in yellow or DBG? -
Thanks for the feedback It is my intention to make BI that can be followed, I'm not aiming for the perfection that is achieved by some of the members here So I'll continue on the track I am on. Still persevering in the photographing it while I'm building it up... (I already found one step that should have been done in another order )

Hi, I'd like to ask you guys for some feedback. I have been working on a new MOC for some time now (using 4 motors with 2 IR receivers... so I'll probably enter this for the TC6). I'm really pleased with the way it turned out, so I am contemplating whether or not to make building instructions for it. The issue is that I do have a digital version of the model, but that is in LDD, so that is a pain in the but for buildinginstructions. I am currently rebuilding the model from scratch, whilst taking pictures of the process. Here is a link to the first steps of it: http://www.bricksafe.com/files/JeroenOttens///AR4C_BI.pdf Now my question is: Are the steps I take clear? Should they be smaller? Or can they be bigger? (the total model has ~2000 pieces, so this will end up in a lot of photo's) Is the quality of the photos sufficient? (I know it is a little out of focus here and there, but I don't want to spend too much time on perfecting the photo setup) Jeroen

A beautiful proof of less is more Very clean design, it's almost LEGO system in its appearance -
Very original models. I never saw something like this before. Well executed
-
I suppose a video showing the functions is mandatory this time?
-
Very nice tuck I love the colourscheme The body of the truck is a little too square for my taste though.
-
How does the crab steering mode work? Does it use the same ratios as with normal steering? That would result in a poor crab steering performance I suspect. Or do you use the same steering ratio for each wheel when crab steering? If so, how do you switch the ratios when going from crab to normal and vice-versa.

Congratulations to all winners. And congrats to the rest of the contestants, it was ( again) a fierce competition.
