    You don't need to use two motors, it can also be done with one motor and the number of degrees. But I assume that this is less accurate after some time. The goal is to connect two bricks without Bluetooth or WiFi and how easy it is to create your own protocol. /Hans

    And the final version: the color selector. On the NXT, a color sensor reads the chosen color. This information is passed with the use of two motors to the EV3, that displays the chosen color and plays the corresponding sound file. When done, this is passed back to the NXT (and you hear 'yes'). Enjoy. /Hans

    Update that demo with two buttons: Pressing the first button on the NXT, the EV3 display starts to flashing red. Pressing the second button on the NXT, the EV3 starts spinning the 24-tooth gear. When the action is done at the EV3 side, a "done" message is send back and the NXT sounds a 'beep'. Let me know what you think. /Hans

    At my Youtube channel, you find a video with a demo of this 'motor protocol'. This is just a simple demo, I am working on a version with two buttons at the NXT brick and two different actions at the EV3 brick. /Hans

    Yesterday, at last... the last order of bricks that I ordered for the Eiffel tower arrived. Started building (of course), but two problems occurred: I think that there is a problem in the building instructions. This was also mentioned in the following Eurobricks thread: http://www.eurobrick...+eiffel +error. The number of pieces that is mentioned on Brickset.com. It seems that the maximum number of pieces is cut at 200.... in the official building instructions, a couple of elements exceeds the 200. For example elements with 4211109, 4211098, 4219725 are all listed at Brickset at 200 pieces. In the instructions, it is set to 304, 268 resp. 254. So, if you plan to build the Eiffel tower by buying the separate bricks like I did, please take care of these two problems. The first is easy to overcome (see my solution in the same thread that mentioned this problem in the first place), the second problem can be tackled by crosschecking the Brickset numbers with the instructions. Until now, I only found the incorrect number if it is greater than 200. Meanwhile, you can find some new "Work in progress" photos on my Flickr page: https://www.flickr.c...068@N06/069M0m. /Hans

    I have the same problem. When I look at the LXF file (also found at this forum), it seems that it was designed like this but it feels not right. How did you solve this? /Hans I solved this problem myself by lowering the inner ring by removing four 2x2 bricks, see picture below. . This works fine with me, although I find it strange that Lego made this mistake. Still not convinced that I made a mistake somewhere...? /Hans

    I have not tried that, but I think that it should work with the NXT color sensor at the EV3 brick. /Hans

    You need the MotorRotation programming block, see example below. More information can be found at the help pages of the EV3, search for Motor Rotation. The difference with the color sensor solution: * The NXT color sensor can both send and receive light, the EV3 color sensor is only able to receive light. So you can only have two way communication between two NXT bricks. * You need a sensor port for the color sensor, and in my situation all sensor ports were occupied. /Hans

    Lego doesn't support a message protocol that is interchangeable between the NXT and EV3 brick. To overcome that problem, I have written a small program in C# to make the translation between the two different bricks. It works fine, but you always need a PC in between. At our blog (see https://siouxnetontr...pc-application/), I have written an article with a completely different solution, namely a 'motor communication protocol'. Enjoy. /Hans

    Some other Lego I owned in the past that are on my wish list to rebuild some day (but it cost time and especially money, so it will be after the summer): Lego 391: Lego 853: /Hans

    My 2 cents: really super! Love the details, like many others the texture of the rug draw my attention first.

    Thanks for the compliments. /Hans

    I join the other replies: WOOOOW! Very nice build, love the details. /Hans

    Like the green color scheme! Keep on the good work. /Hans

    Not yet. Can do that if you want. The Lego 392 is not completely finished yet, I am still waiting for two bricks that I have ordered in Denmark (via Bricklink). /Hans

    The Green grocer was my start in collecting the modular buildings. Since then, my collection yearly grew towards the 8 buildings I own right now. Besides that, I started also to collect the advanced models like the Sydney Opera House, the Tower Bridge and the Taj Mahal. I really wanted to have the Modular buildings Cafe Corner and Street Market. Plus the Eiffel Tower as well. But these buildings are too pricey for my budget. So I started to collect the separate bricks and rebuild with sources as Pick-a-Brick, Missing Pieces and of course Bricklink. So all new bricks for these projects. The Cafe Corner is almost complete. Unfortunately, some parts are too expensive (the price of one door is about 50 euro!) And some parts (like the windows) I have replaced with cheaper solutions. The result is good enough for me. About 1/3 of the bricks I already had in my collection of new bricks. The rest of the bricks were just below 200 euro's. Not a bad price if you compare with a completely new one. And now I am going to wait if the doors will be cheaper one day. For the Street Market, the same applies: I have collected most of the parts, but not all of them. Still thinking of some cheaper solutions with (almost) the same result. The bricks are waiting in a box, ready to be build. Currently, I am in the process of building the Eiffel Tower. The good news is that I have ordered all of the parts. Half of the bricks were already in my possession, the other half I needed to order. Total cost of the order is appr. 300 euro's, so in comparison with buying it new for the current price, it is relatively cheap. The base plates were delivered in the wrong green, so I need to re-order that one day. Can't build right now, I am still waiting for the "Missing pieces" delivery. On the picture, you see the Work-in-Progress. Not only building the sets is nice, but the process of searching all the pieces was nice too. I found out that Bricklink is normally the most cheap (or should I say, less expensive) but this is not always true. Next, the Missing Pieces site and Pick-A-Brick (both officially Lego) have different prices. And sometimes one site says "sold out" although the other site has still availability. Strange but true. Enjoy. /Hans

    Don't know if this section is the right place for this. Wanted to share the following: I have rebuild my old Lego with (mostly) new bricks. The result is in the picture. The Lego Technic 850 Fork lift was the first Lego Technic set that I got when I was 9 or 10 years old. The Lego 392 Formula One was also one of my favorites. I really loved the smooth lines at that time. A huge difference with the Lego of today. The Lego 396 Thatcher Perkins was a set that a friend of my had. He asked me to build it for him, since then it was one of my sets on the wish list. But too expensive at that time. Building it from scratch was a real "back in time" moment. All the bricks are new, besides the wheels. The stickers are not available anymore, but the result is good enough for me ;-) /Hans

    Nice build! /Hans When the Emerald was released, I bought three boxes. Price was 99 euro at that time. I sold two of the loco's for 60 euro each, so the total train (one loco plus 3 wagons) was 180 euro in total. When I look at the prices right now, I'm glad I didn't wait ;-) /Hans

    Thanks for the replies. Here is the link to the two files: https://www.dropbox....kavFz2JSxa?dl=0 The LDD file The document that describes how to modify the switch (remove the 'click') Please let me know if there are any questions. /Hans

    Hi Baard, Looks really nice (understatement ;-). Thank you for sharing the info. /Hans
  22. Hanso
    Thanks for the replies and remarks/suggestions. Yes, of course you're both right. I never claimed to have the most superior solution. It is a solution that works (and I never try to minimize the number of bricks ;-). For the Mindstorms version, we want to show how the internals work for children (we always demo on Lego World in Utrecht). So we never hide the mechanism. For the PF version, it is just a small prototype and it would (of course) be more nice to hide it into a loco or wagon. /Hans

    Yesterday, I build a version with a PF motor. The result is shown in the LDD picture below. /Hans

    As you state, it is the whole experience. Thanks for the nice compliment. /Hans

    Hi all For our project "Fully automated train layout" (more information can be found here: https://siouxnetontrack.wordpress.com/), I have designed an automatic train decoupler. A video of the first test run can be seen here: .For our Lego World 2015 layout, we have adapted the decoupler (expecially more speed) but the basics remain the same: The wagon(s) behind the train are pushed away to overcome the magnetic force of the coupler Loco moves forward (this is needed otherwise the magnetic force pulls back the wagon if it is not too heavy like the one in the picture above) Because our train layout is fully automated, Mindstorms is used for the controls. But the same principle can of course be made using a PF motor and PF receiver. Enjoy. /Hans
