W.I.P.: (Statuses are as follows: Under Construction is a W.I.P. that is making good progress, and that I am frequently working on. On Hold means that the project is not moving forward, and will not be updated in the near future. Abandoned means that this project is likely never going to be completed, either due to technical hurdles, or lack of interest.

Project Yui (Status: Abandoned )

Super Sport 8070 (Status: On Hold )

W.I.P. to be posted:

Project B.O.R.A.T. (Under Construction )

Future projects and ideas: ( I have no idea when any of this will be completed, so don't ask.)

The Big Idea Thread

10 speed remote control gearbox

18 speed remote control gearbox

reciprocating linear actuator

Unimog G (based on Efferman's design)

KY Tank (big honkin' tank with subtractor and 3 or 4 speed gearbox. it's also going to have a working turret and firing mechanism. )

Landkreuzer Monster.

(another big tank. Fully functional, and really detailed. 8 motors for drive, 1:24 scale. will be about 4.5 feet long when complete. )

That's all for now, i'm going to update whenever i feel like it.

Okay, I'm wondering something. Should I post work in progress pictures in this thread, or should I make new threads each time, or maybe a mixture of both?

Anywho, here's an old project I made a long time ago.

It's my second ever Trial Truck. I used to have more pictures, but my mom deleted them. It's loosely based on the chassis of Nico71's second Unimog, and the body is based on Andrea Grazi's Big Foot pickup truck.

Definitely do NOT make a new thread every time!

Anyway, MOC looks good. Its huge! Do you have problems with the frame bending?

No, not at all. Anyway, I'm going to make a new post in this thread for some projects, namely small ones, and have individual threads for especially ambitious projects.

Here's another thing I made: ACC Retro.

It's a very simple car, that uses two old motors for propulsion.

Instructions now available on Brickshelf, and Rebrickable. Enjoy!

Edit: links to instructions have been added.

What, nobody likes the car? Ah well, this sure ain't no popularity contest.

Anyway, here's a preview of a project I'm currently working on.

The geartrain. the blue axle is for steering, and the red is for drive.

This is the axle of a next-gen trial truck that currently has the project name BORAT.

That would be:

Big

Off

Road

Armored

Truck

There is, as a matter of fact, an older version, which uses 3 live axles and has four wheel steering. It's currently buried, so pictures will come later. The new version, however, has 6 wheel independant suspension, and each wheel can turn through 360 degrees.

This is just a preview, there will be a full work in progress thread, as this is very ambitious. Stay Tuned...

Hi Saberwing,

Is your new project something like the ETF mining truck (www.etftrucks.eu) it has about the same way of steering. There was sometime ago a thread about the ETF trucks maybe it inspired you.

@vliet: Not quite. The axle on an ETF truck is far, far more complex, and has two wheels, not one. But yeah, I was sort of inspired by that. However, rather than the complex suspension in an ETF truck, this is much simpler, and works differently.

@DLuders: Yeeeaaahhhh... Not quite.

I so need a better acronym. Any suggestions?

Anyway, I've got a teaser of a new idea:

More info and pictures will come on Monday, so stay tuned, same Lego time, same Lego channel.

[timslegos]

I look forward to more info on the double cylinder pump! How does it not destroy itself?

Well, it does. The double big cylinder pump actually works very badly, and there is much self destruction. But more on that later, after I explain the little one.

Here it is. It's double acting, which means that airflow is more consistent.

It uses a M motor to rotate a crankshaft, which is attached to an axle, and in turn connected to a #2 axle joiner, which slides back and forth, driving the pumps.

The crankshaft in another position.

The underside.

This whole assemblage was actually inspired by the idea depicted below. I full credit Yoshito Isogawa for coming up with the guts of the pump, so thanks to him.

This also inspired the bigger pump, which works horribly. The connection to the pumps falls apart, the axle on the crankshaft comes off very easily, and said axle bends scarily when the pump is in action. This pump works in much the same way as the little one, except the pumps are supposed to directly cancel each other. It still performs terribly. Ah well, back to the drawing board.

Pictures:

If anything was unclear, or if you want more pics, just let me know.

Thanks for reading!

[timslegos]

That is a very interesting way of powering both the large cylinders! Ingenious application of a technic principal. How well does it work?

Ingenious as it may be, it still works terribly, and constantly self destructs.

Okaaayyy... How about another old, old project I've got to post before demolition?

First, some background information. Back in January, I was working with my FIRST Robotics team (Team 2083) on our robot. We still had not decided on whether we would go with a pivot platform, in which all wheels can steer independently, or a platform with Mechanum wheels. I was for the pivot drive, and to argue my point, I built this:

(Sorry for the terrible pics )

Ultimately, they did not buy my argument, but nevertheless, I had this. It has 4 XL motors for drive, and 4 M motors for steering. It was designed to be as simple as possible, and went together in a night. Controlling it was a major pain in the behind, however, as I had to manage with just regular remotes. It would have worked much better with an NXT brick, but I had no time to program.

Another Pic:

And a view of how it looks in LDD:

I have it rendered in LDD, so if you want to make your own, I'll post that. This model is still mostly intact, so I could make a video, but only if you people want one.

Thanks for looking.

P.S. How could I make this thread more popular?

[Saberwing40k]

HA HA, I'M BAAAACCCCKKKK!!!!!! And I'm better than ever.

Okay, nobody seems to respond to this thread , and I think I've figured out why. My first post has no pictures! Well, that's going to change very, very soon. I'll be indexing all of the stuff on this thread in the first post, and that should work better.

Now, before I post my big update, I've got some bad news. My house is getting a new kitchen, which means we won't have one for the next 2-3 weeks. This also means that me and my family will be moving out of the house for 2-3 weeks, which means that I'll have severely limited access to my computer and my collection for that period of time. On top of that, my school year starts tomorrow, the 20th. , so I'll have much less free time. Joy to the MegaBlucking world.

Okay, enough with the complaining. It's time for a big update!

This is version 1.5 of Project BORAT, which for version 2.0 will be renamed.

It's a 6x6 truck with all live axles, and it uses a pushrod system shamelessly pirated er, borrowed from efferman. The front and rearmost axles steer, and use portal hubs from the 8110 unimog. But more on that later. This thing was abandoned in this state, which is why it looks so incomplete.

This picture shows the steering angle, which does not look all that impressive, but works fairly well, given how long the truck is.

The suspension, in action. As a matter of fact, next to none of this is actual suspension travel, with most of it being chassis flex. Hmm, maybe I could actually use the inherent flexibility of Lego parts to my advantage...But later.

And this is a closeup of the front axle, clearly showing the Bionicle joints used as a Panhard rod, borrowed from Miezel.

Look him up on Brickshelf.

(the rod on the front axle doesn't work all that well.)

Okay, this picture is terrible. Sorry about that. It's meant to show the front substitute torque tube, which was made out of a pair of CV joint hubs. This was also not my idea, but I can't remember who came up with it originally. This picture also shows the top end of the steering system, which is not connected to a motor, or even hard mounted. It is just sort of tacked on.

The rear drive mechanism, which drops down the main drive shaft, and connects it to the rear 2 axles. The steering shaft for the rear axle passes through the 16z clutch gear in the center.

The rear axle. The Panhard rod back here works much better than the one in front. However, the steering back here is a really terrible design, and works poorly.

a close up the pushrod mechanism.

The 2nd axle. It's the most successful of the bunch!

A closeup of the substitute hub.

The first axle. This gives you a better idea of the steering angle it achieves.

A closeup of how the hug interfaces with the axle. It uses two of these on each side.

Another view of the substitute torque tube.

The other end.

The third axle. No description needed.

The chassis, sans axles.

Front.

Middle.

Rear.

The torque tube block.

...

These three pictures just show more views of the first axle.

...

There is actually another version of the front axle, but I'm too tired to post it.

Well, that's all for now. Please, oh please tell me you like this, or at least where I need to improve.

Oh, and version 2.0 is still incoming.

[z3_2drive]

I think this is really cool, beats me why no replies, keep working on it, i'd personally use four link at front...all that negative caster... and really strengthen the chassis, like with a second level, like effermans g... best of luck!! school starts tuesday for me

[Lauris]

I think you have to add more beams to the chassis, so it is more rigid. Keep us updated, looks it's gonna be nice

[AndyCW]

Seems interesting. I like to see WIP threads. I have to agree about the geometry of the front axle though. A four link or angled torque arm would correct it. The other thing I see is that as the front axles tries to compress it travels forward. This will inhibit its movement over bumps at speed. Looking forward to seeing the finished project. Keep us posted please.

School starts for me soon too. Full time school. Full time job. Full time parent. Where does my lego addiction fit into this?
