This is a "Underwater Scooter". It's a handheld device to propel a diver forward. Similar devices can be seen in the James Bond movie "Thunderball".

These pieces are frequently used for decoration now, but they were originally used for sliding doors, particularly on train sets. Here's one of the first uses from set 7838 in 1983: While they could be used in structures, these were frequently used for putting doors on the train cars themselves: These parts can also be used to create tracks for other ...

In addition to what jncranton wrote, the plate with the rail is a perfect fit for sliding in the brick with groove: You can see an example of that technique in the Cloud City set:

This is a Minitalia brick - Lego produced different bricks for a while in the seventies for Italy (per Gary Istok's latest information: because the original LEGO was deemed too expensive). Minitalia bricks have weaker plastic (which shows on the studs on your brick) and don't use the Tube system underneath the brick, but an older patent which has the X ...

The windscreen you mentioned has been retired, however you can still get it on BrickLink. It is available inexpensively in several colors: http://www.bricklink.com/catalogItem.asp?P=6152 If you want to use a modern version, this wedge is pretty close in shape and is available in current sets: http://www.bricklink.com/catalogItem.asp?P=6153b As a reference, ...

Parts with and without bottom tubes are nearly always interchangeable in normal building scenarios. However, there is definitely a functional difference. Not having bottom tubes generally does the following: Reduces clutch power. There's one less surface for the stud to produce friction against. Allows for lots of different connection points along the ...

These pieces are not included in the set. Motorizing this set requires the addition of a Power Functions motor as shown here: You'll need the Power Functions Motor Set (8293) if you'd like to motorize your truck. This can be ordered from shop.lego.com or other online retailers. It's usually hard to find in stores, but if you have a LEGO store nearby, they ...

Yes, this is a 30375 - Torso Mechanical, Battle Droid in black. It's a little difficult to identify as it is lying on its belly, and hence you do not see the characteristic single stud front of this piece.

This is part is commonly found in the Divers theme back in the late 90's (http://brickset.com/sets/theme-Town/subtheme-Divers) The part in question is a minifigure accessory: http://www.bricklink.com/catalogItem.asp?P=30092

1 x 6 Bricks According to BrickLink, 1 x 6 bricks like the ones you describe were made between 1955 and 1969. 4 x 6 Plates According to BrickLink, there were no 4 x 6 plates with square holes (so-called waffle-bottom plates.) There were, however, 4 x 8's made between 1954 and 1971. Windows Don't know... White Blocks with Clear Inserts The white ...

It's 30191 Strap 12 M: This is listed as x169 on Bricklink and Peeron, and is also called a stretcher holder, as that was it's original use when it was first created in 1998: Edit: It's acceptable and even preferred to post new questions to identify new parts. With that said, the wing part in your updated question is 15082 Animal Wing with Shaft:

The sloped face of the 2x2 brick is 16mm across by about 11.3mm tall.

It's definitely Minitalia and since you're Italian let me suggest a very recent Italian article with the most recent findings about the history and the actual reasons behind the existance of the Minitalia line! I also recommend Gary's book, it's really great (and he's working on a new edition that will include these recent findings).

I can't find any evidence that a 2x2x4 piece has ever existed. Bricklink identifies a 2x2x3 brick, and there are many sellers around the world that will happily sell you 16 dark stone grey pieces for pennies/piece.

As you have probably guessed by now, there is no easy solution to your question. It all comes down to computer vision. In this solution, Akiyuki built a massive machine out of LEGO bricks, a camera, a scale, 2 Mindstorm NXT and, which he fails to mention in is parts list, a computer and some electronics. Computer vision is complex, and making a working ...

Tom Alphin has a template of labels you can download and print with the appropriate label printer. Sample:

They both appear to have the same part ID despite being quite different. Sariel answers most of your questions in The Unofficial LEGO Technic Builder's Guide. toothed half bush with a cutout The second variant, the toothed half bush with a cutout, is exactly what its name implies: a copy of the previous version with part of the axle hole cut ...

Another type of pullback motor has a detailed structural disassembly here: Picasa album. I think your motor should work mostly the same way, but I wasn't able to source such internal pictures.

This gear can only handle a certain amount of torque. Above this torque the gear starts to slip internally. This pervents damaging the motor when the some part of the construction after the gear gets blocked. Lego uses these gears ofter in constructions where there is a end of stroke that blocked the motor from turning, for example a winch or other string ...

Bricklink tells me that 6102555 is Tile, Round 2 x 2 with Bottom Stud Holder with Pizza Pattern and 81867 is Tile, Round 2 x 2 with Pizza Pattern which according to the 3D model is the old style with the X on the bottom. Other than that, they seem to be identical.

First of all: LEGO prices fluctuate depending on retailer (LEGO.com, Wal-Mart, Target, Toys'R'Us, etc.), so "cheapest" also depends on the time of year and the retailer you look at. Secondly, are you only interested in a PowerFunctions motor, and is the set you ask for just a vehicle to get the motor? In that case you might want to know that you can just ...

According to LDraw, the slot is 8 LDU wide (1 plate, 3.2mm) and 5 LDU deep (quarter module or stud, 2.0mm). Here's the relevant quads from the LDraw file for reference:

Yes, visually the simple smileys are the same now as in the past. The difference is in the stud. Some have a stud like what you have pictured above; with an open stud and others have a solid stud. Other than that, the face itself is exactly the same. You can three all three versions of the stud here (solid, recessed open and recessed blocked) here: ...

It's tough to predict where such a small number of pieces came from, but some are likely from the Hydronauts theme, specifically Hydro Crystallisation Station (6199): This set includes the chromed headgear with studs on the back as well as the printed tile that is already attached to the back of yours. The minifig utensils are likely from Mobile Outpost ...

In the case of this item, it means that the gear will slide freely along the axle it rotates around.

Are both of these always interchangeable? Yes and no. They are 100% compatible with the standard LEGO building system, but you may be able to use the bottom-tubeless elements in arrangements that wouldn't work with a standard brick, and vice-versa. If not, what are the cases where you would absolutely need no bottom tubes? Bottom tubes were introduced ...

jncraton and CreationEdge have both explained what the tubes are for and mentioned two advantages to not having them: nicer-looking clear parts, and connections that aren't aligned with the system stud grid. The main advantage to having them is the clutch power it adds: in a 2x2 brick such as the slope with no tube, each stud touches two walls, but with a ...

Looks like it's 4476a or 4476b.
