All new magnet sets introduced by LEGO will have the figures glued, as will any re-makes of existing sets. History In 2009 LEGO started producing sets of minifigures standing on magnetic bricks. At that time, the figures were removable, although some felt that they were of lower quality than the figs in regular LEGO sets. In early 2011, however, LEGO ...

There are MANY companies that offer third party stuff for NXT: Mindsensors, already mentionned in pcantin's answer Vision Subsystem - Capable of tracking up to 8 coloured objects Touch Panel Numeric Pad IR Obstacle Detector Sony PS2 Controller Interface Line Sensor Array Accelerometer Realtime Clock Power Meter IR Distance Sensors (Long/mid/short range) ...

The term acrylic is used for many mediums, like acrylic paint (liquid), acrylic fiber (clothing), acrylic rubber (flexible) and acrylic glass (really hard). So, as you see, it is possible to make those capes out of a type of acrylic material.

It is fabric - probably cotton or polyester - coated with an acrylic substance that makes it more durable and tear-resistant. You can easily print on acrylic-coated fabric using standard laser printers. You can purchase acrylic-coated fabric through suppliers that sell sign-making supplies as well as art supply shops.

I found them. The capes were packaged in a small, unmarked, rectangular, white, cardboard box that was taped shut. Apparently, this little box came with the set, but someone else assumed it was filler trash and put it on our recycling queue. Considering the capes are the only items out of stock besides the Cave Troll, it is possible others may be simply ...

I am not sure such a case exists for the HTC Desire. All of the LEGO style phone accessories I have seen in the past have been for the iphone. A bit of searching turned up these items: What appears to be a case with LEGO compatible studs (for iphone) Check out this page for other LEGO relates accessories and a picture of the above case in use with actual ...

Just put them in boiling hot water and leave them for 5 minutes then take them out, straiten the torso and it should come off. If it doesn't come off then get a knife and wobble it a bit and there will be no studs in the legs and you can take the whole body apart - I have successfully used this method.

I have not heard of this problem before and I'm a member of several LEGO communities. However it is quite possibe that a batch is missing the parts, or even just your one box. I would suggest that instead of trying to get the replacement parts online, just call customer service and get them that way. Perhaps they are holding back on online stock because they ...

About 8 to 10 years ago there was more RCX-compatible sensors makers on the web. Today, I don't think we'll find them unless we dig into the Internet Archive. It looks like Techno-Stuff is still making some RCX-compatible components. Also, Mindsensors was making RCX-compatible components also but I couldn't find links to them through their website main ...

It's probably a 3rd-party LEGO-compatible accessory, several 3rd-parties make such military themed accessories. LEGO doesn't make very many modern-day military-themed pieces and I found similar pieces on one 3rd-party accessory shop. It's not an exact match, but it's pretty close. It might be that you have an older version of their product, or some ...

While Alexander's answer is completely correct, I wanted to provide an alternative that may work a little better while being a bit more expensive. Buying a motor and battery box is certainly the cheapest way to get a spinning motor, but depending on your grandson's collection, this might not provide the best experience. In order to build creations that ...

You say he is looking for a "Power Motor", which sounds like he is referring to the LEGO Power Functions line. The bare minimum you need to get a spinning motor would be one of the battery boxes and one of the motors. Battery Boxes: AA Battery Box AAA Battery Box Rechargeable Battery Box (requires Transformer 10V DC) Motors: M-Motor L-Motor XL-Motor (...

I can't find an official source for this statement, but with the exclusion of a few rarities like test bricks, and perhaps a few other cases, every piece of genuine LEGO will have the brand stamped on it somewhere. You've taken photos of pieces together that clearly ought to have come from the same mold, where one displays the LEGO brand and the other does ...

If you subscribe to the Lego Club (availability depends on your location) you will receive the official Lego Magazine and often a free poster is included. The March/April 2014 edition contained a reversible poster with the Lego City theme on one side and the Disney Princess theme on the other side. Occasionally, you may receive promotional Lego posters with ...

Good places to find parts include: Thrift stores, car boot sales, jumble sales. Sometimes you get lucky. eBay is a good general source for parts... as long as you can find what you're looking for. LEGO's Pick-a-Brick (PAB) service is good for for common parts. LEGO's replacement parts service is better for less common parts from newer sets. The range of ...

I've used iron-on patch material (the thinner twill variety that comes in bright colors) with success for my kids' minifigs. I cut it out with fabric scissors and use a good hole punch for the holes. Takes about one to three minutes a cape depending on complexity and is $2.47 at Walmart for a 4 pk of 5"x5" patches.

There's lots of third party SENSORS to attach (see very helpful list from Philo), but I found it hard to find any info on third party MOTORS to connect to EV3. Pretty much only the mindsensors.com extensions to connect RC servos and position encoding adapters to slap on power function lego motors. So I took to the LEGO hardware documentation and put together ...

My son has a Lego Movie poster on his wall that he got in the "Mega" magazine a few weeks ago. I think it's A2 sized. We're in the UK though (I don't know where you're located) but I'd recommend looking at any magazines in shops to see what they include - some of them are a little expensive for what they are, but they usually bulk them out with free "toys" ...

If your grandson has lots of Technic pieces, such as gear wheels, axles, beams with holes etc (if he knows his way around Lego he should be able to confirm that pretty easily), the Lego have a good starter set which contains a motor, battery box and a few other pieces. It's how I started updating my old LEGO Technic sets from the early 90s to be motorised ...

Remember the BPA scare? It's all but a crime to release a product that even thinks about having BPA. But I did the search anyway, and no, there is not any in this or any other LEGO product I can find to date. LEGO is pretty good about nontoxic products, drinking use intended or no. I mean, they're made for kids. Good question though.

Besides posters, another thing you might consider is cloth display-banners. If you live close to a LEGO store or LEGO retailer who uses these, often all you have to do is ask for them when they go out of season. Here is an article featuring many of these beautiful banners. They are really pieces of art and they are large too: http://thebrickblogger.com/2013/...

One way to remove them would be to carefully drill out the studs. You would need to put the legs in a vise of some sort (covering the metal jaws with something that won't damage the plastic) and use a drill bit just slightly smaller than the studs. You would probably then need to cut out the remnants of the studs and glue, or at least cut out enough so a ...

In addition to these helpful answers, I'd like to add that the reason there are so many 3rd party devices and options is because the NXT supports an incredibly wide variety of electronic and data protocols. The NXT can directly interact with sensors over: - Bluetooth SPP - RS-485 (only on Port 4) - I2C - Analog So pretty much any robotics/hobbyist ...
