A regular LEGO base plate will work with DUPLO bricks. As demonstated in this question, the two systems are compatible in a number of ways. Here's an example of System base plates with DUPLO bricks attached:
It should be noted that not all DUPLO bricks will be able to connect to a System baseplate. Some examples of incompatibility are round bricks and some ...
The problem is that while in general MegaBloks bricks fit with LEGO bricks, the quality control on the MB bricks seems to be much lower*, so the bricks/studs and holes are not always the same size.
As an example, I recently acquired a MB HALO Covenant Banshee ship for my son, and can safely show that:
The holes in studs do not readily accept rods (in this ...
The current Mindstorms sets are completely Technic orientated and use the Technic pins (i.e. [part:3673:7]) to connect to the newer Technic Beams (i.e. [part:32316:7]) as well as the original Technic Bricks (i.e. [part:3894:7])
The various different size pins and axles are the way to interchange between these.
"Communist LEGO" is a comprehensive list of all the LEGO imitators and clone brands. It is an interesting read:
Keep in mind that, while clone brands may be cheaper at the beginning, they have minimal or no resale value, and thus can end up being more expensive than genuine LEGO. Because of LEGO's ...
I have 2 Banbao set from before the lawsuit with Lego (minifig style minifigs) and they are more and less compatible with lego, the pitch between the studs is the same. But there is some remark I noticed within comparing both brands for a few minutes.
Studs are higher, a Lego plate on a Banbao brick will leave a small gap between both bricks
Plates are ...
since the bionicle-pieces only have holes for technic-connections and no studs to use then directly with bricks, you'll have two possibilities:
build some kind of "adapter" using technic-pieces. you could use pegs to connect the bionicle-piece with some kind of technic-brick.
put the studs of your system-bricks into the bionicle-pieces technic-holes - which ...
LEGO used to sell Converter Cables for Mindstorms NXT at a price of £8.99 / US$9.99 for 3 cables at their online shop, they can still be bought online from stores like Bricklink.
Considering the price of each cable converter it may be worth purchasing newer sensors/motors that are more advanced. The NXT system cables are separate from sensors and motors and ...
The LEGO Group have advertised the EV3's excellent backwards compatibility with NXT.
As the cables are the same, the EV3 will work with NXT sensors, motors and, of course, LEGO Technic bricks. RCX sensors will work with the aid of converter cables.
Software designed for programming the NXT will not work for the EV3 as the NXT runs firmware, but the EV3 ...
They are not compatible, the teeth are completely different.
Notice that the red old gear has 9 teeth and is the same size1 as a current 24-teeth, as illustrated by below:
The axle hole however is compatible, so you could have a construction using both types.
1. Actually, the distance between axles to have two of these red gears mesh is the same as the ...
You can absolutely run RC and PF trains on 12V track. You can leave out the center conducting rail since it won't be delivering any power to the train, unless you are planning to run both 12V and remote trains.
The main LEGO train sets have all used the same rail gauge, which is the main thing that matters.
If you'd like to use both your 12V track and the ...
Is it possible that you are thinking of this goblet (2343)?
This part was fairly common, and it was introduced around 1985, so it was probably in your collection.
1x1 round plates attach securely to the top as shown in this lamp from the Pet Shop:
Yes, you can use all RCX sensors and motors with a NXT brick. Don't forget about lamps, too.
The connections are different though, so as Ambo100 says, you will need converter cables. However, if you don't want to pay the full price for them, you can also make some yourself which isn't really that difficult.
The other thing you need to consider is how to ...
The first gear wheels, or cog wheels, were designed by Knud Kristiansen around 1964 or 65; the original Danish design patent was filed on March 1, 1965.
Under licence by LEGO, Samsonite manufactured and sold these gears in the USA from 1965-1972, and in Canada from 1965-74. The gears had studs on the top and tubes on the bottom. They could be made turnable ...
I don't have this particular piece but my advice for most 'non-standard' connections such as these is to use a part that is flexible enough to fit the gap.
The 'Technic, Axle Connector Double Flexible' piece under compression can make a snug enough fit to mount a sharks head.
In this example, you can use two Technic Axle-Pin attached to another two ...
In short, yes it's perfectly safe to run your old 9v motors from your Power Functions battery box.
This excellent online reference has a lot of information on various LEGO motors. Both the old 9v train motor and the Power Functions train motor are listed.
The information on the site shows that the characteristics of the two motors are very similar with the ...
Dimensions are, respectively:
3651 - 0.8cm x 1.6cm x 1.1cm
32013 - 0.8cm x 1.6cm x 0.8cm
Distance between one axle and end of another also did not change. So for most builds it should work.
Obvious lack of studs
Use as in Lego Technic Universal Set 8034 as a locking mechanism for lift system, as seen on the box:

My mother in law thought a set of MegaBlok duplo sized sets would be a great present, and while there are some fun elements in the set, overall the real Duplos are better quality, to the point we decided to sort out the sets and keep the brands separated. At first we had them mixed together, but the MegaBlok ones seem to be more flexible (perhaps thinner ...
It really depends on what you mean by "accurate." Most (probably 90% or more) of Mega Bloks elements have identical, or at least functionally identical, LEGO elements. However, there are a number of Mega Bloks elements that you can only approximate with LEGO elements. For example, Mega Bloks hinges rotate around the center of mass ...
It is designed to handle curves that are found on CITY track. Here is the detail from middle car. There is tongue and groove that allows the middle wheels to slide left and right to enable curves. I will post a video of a powered train pushing it, if needed.
All LEGO train tracks have had the same gauge, so newer trains will fit old tracks, including 12V/4.5V. Since the wheels themselves are not exactly the same, you may run into some small issues at points, but it should be OK most of the time - and using RC track wouldn't fully prevent the issue anyway. (If anything, I suspect trains woudl actually derail more ...
Welcome to LEGO Answers! That's a great question.
I don't actually have this set, but I believe the issue is that the linkage piece that you are using comes in two separate variants:
The variation is subtle, but the small flanges that you mention in your question were added in a variant that came later than the set you are trying to build. This is what ...
Welcome! COGO is a clone brand, and hence not generally used around here. COGO bricks will work with LEGO, however, the quality, finish and fit of COGO bricks is significantly less than LEGO's, so I would advise to return the COGO set and buy a (smaller but) better quality LEGO set instead.
The length of the wire is another thing to be aware of. The wire attached to the motor in 8293 is only slightly more than 20 centimeters (might be a few centimeters more, I don't remember), you can double that by putting in the switch which has about the same length of wire, but it's still not much. I don't know how long the wire in 8700 was, but it looks ...
The motor you have linked is indeed quite old and as far as I know, not compatible with anything newer. Seeing that it works with simple DC current, it wouldn't be hard to construct a converter cable, but it is still some work (especially reducing the voltage from 9V to the 4.5V required by this motor).
The next generation (9V system: large motor, ...
It appears that the goal of the nanoblock producers is to make "the world’s smallest toy building blocks"1. And they appear to be too small to be compatible with LEGO. See the following video comparisons of the sizes.
