    One of the constraints that we use, is that we don't allow ourselves to use non-Lego stuff. The only exception that we made so far, is the use of licensed sensors (Codatex and HiTechnic). But it seems that we don't need that exception anymore. And yes, I know that we're sometimes making live more difficult that necessary ;-) /Hans

    The last years, we have used a NXT brick for controlling the train. For Lego World 2017, we want to use EV3 bricks only. Since the RFID sensor is not supported anymore, we needed another way to determine the train location. I have build a proof of concept of a loco: Wheels are directly connected to a EV3 medium motor Location detection based on a color sensor (the combination of yellow, red and green makes a unique pattern) And it works fine! A video of this proof of concept: Of course, the train needs a bit (... ) of restyling ;-) Enjoy, Hans

    Thanks for your reply. At Lego World, the (new) delivery station drew the most attention (in the positive way ;-). Most people didn't understand what it would do, until they saw the station in action. The mechanism of pushing the containers from the wagons, lifting the containers and the lockers: it all worked as I designed it. I learned a lot in the last years of building, for example: the first items were totally not designed for transport-ability. Nor was it designed for three or four days of continuous play, so we needed a power supply attached to it. But attaching a power supply is not that easy for a moving object, like the crane. For the new buildings, I took most of these 'abilities' into account at the design phase. Would it be interesting to write a longer article about this?

    Thank you for your kind words. It was also fun to do. I already have new ideas for Lego World 2017! Hans

    If the children asked me what it was, my answer was "It is a candy delivery system". But if the parents asked me, I told them it is a Mind(fullness)storms machine: a full run with four candies took about 13 minutes ... ;-) We estimate the total building time (so both the Lego structures as the C# application) somewhere between 1500 - 2000 hours for the whole team in the last year. Some parts are reused or improved from earlier years, if you add that to the total time I think you should double it.

    The Ticket Dispense Unit (reader part) is ready: An article about the principles of the ticket reader can be found at our blog: https://siouxnetontrack.wordpress.com/2016/09/28/ticket-dispense-unit-reader. On Youtube you can find a video of the working reader part. The dispense part will probably not be ready before Lego World. Focus is now on getting everything working as a whole. Enjoy, Hans

    Didn't expect it to sell it that fast ... So, in case you were interested... you're too late. Only have some motors and sensors left. Regards, Hans

    Dear all, I'm selling a lot of Lego Mindstorms NXT stuff. I have for sale: 2x Lego Mindstorms NXT bricks 9841 + 2x rechargeable battery type 2 (9693) 2x cable Packs (still sealed) 10 x 9842 NXT Servo Motor 7x 9843 NXT Touch Sensor 2x 9846 NXT Ultrasonic Sensor You can buy via Marktplaats (only if you live in the Netherlands) or via Bricklink(store name = L.E.G.O. StoreHansOdenthal). Of course, everything is still working fine and in good condition. The more you buy, the cheaper it gets (relatively, of course ;-). Kind regards, Hans

    Dear all, Our visit at Lego World 2016 in Utrecht (the Netherlands) is approaching really fast now. And we haven't finished building (both the constructions as the software). Like almost any "real" project, we need to get into overtime modus ;-) Anyway, the layout has been planned to perform as follows: The visitor chooses a color using the Wheel-of-Fortune color selector (click for a video impression) The Ticket Dispenser Unit picks up one ticket from the stack. I am planning to use a vacuum grabber for this, a proof of concept can be seen . The ticket contains a number that can be read by the TPU-reader (see below for the proof-of-concept). The ticket is now handed over to the visitor. The chosen color is now coupled to the ticket and the visitor can see the progress of the candy pickup at the monitor. This process is repeated four times: the train will deliver four candies in one run. Indeed, new functionality to speed up the process. More speed means more happy kids. During the process of handling the four visitors choice, the candy factory has already started and delivers the candy in the chosen colors to the candy crane in a container. The candy crane puts the container in an empty wagon in the awaiting train. The train pulls four wagons and the crane will load them all before it leaves the crane section. An impression how the crane picks up a container and loads the train, can be seen . The train drives to the delivery station. The four containers are pushed to the rollers. Click for an impression of the push mechanism. The containers are lifted to the separation mechanism: the candies are removed from the container and moved to the lockers. Click for the lift mechanism and for the lockers. Finally, the four visitors can one by one insert their ticket into the ticket reader, click for a video of the ticket reader. The ticket reader opens the correct locker and the visitor can grab his candy. Done. To make all of the above happen, a total of 1 NXT brick and 11 EV3 bricks plus a laptop with a software application (written in C#) is needed. I'm not sure if we will finish the ticket dispense unit in time. As a fallback, that will be done by the operator. However, the card (number) needs to be read in order to make the coupling between the chosen color and the ticket. That part of the TPU is now being developed. The first prototype looks as follows (click the image for a video): Enjoy, Hans

    One of the missing elements of the layout, were the lockers that store the candy just before delivering it to the visitors. I was looking for an interesting door mechanism and one of the team members came up with the idea of an iris. Below you find the work in progress. The four locker doors can be opened/closed separately. An infrared sensor is used to determine if the visitor's hand has been retracted. Opening and closing of the door that works like an iris, can be viewed at our Youtube page: More photos of the Work in Progress at our Flickr page: https://flic.kr/s/aHskA82jPV Waiting for some pieces (in back order) to finish building the doors. Please let me know what you think. Enjoy, Hans

    Hi all, I am selling the Volkswagen Beetle (10187) that I build myself, see the thread about finding the missing pieces: http://www.eurobrick...howtopic=111319 In case you're interested, please note that three type of bricks were too expensive and therefore have been replaced by other bricks. See picture below for the pieces that have been replaced: The original set needs 61 pieces of the dark blue plate (2x2), in my version only 13 pieces are available. The rest of the bricks are replaced by 2 pieces of the 1x2 plate. But the result is still very nice. Apart from the missing sticker, you won't see the difference from the outside. Almost all of the bricks are newly bought. Because it is not original, the price is relatively low (275 euro). If you're interested, drop me a note. Best, Hans

    Yesterday, I received the last batch of missing bricks and finalized building the Color Selector. So, I now proudly present the finished Color Selector that will be used as the 'physical user interface' for Lego World 2016. More photo's can be viewed at our Flickr page: https://flic.kr/s/aHskAfyhDv and videos can be found at our Youtube channel: http://www.youtube.c...siouxnetontrack. Enjoy, Hans

    Uploaded some new images of the (almost) finished Delivery Station for Lego World 2016 at our Flickr page: https://flic.kr/s/aHskxcfwSV . Only the four lockers need to be build (and first need to be designed ;-). Enjoy! /Hans

    Like a real project, we have a list of tasks to perform. With a 'hard' target of the demo at Lego World. The vacuum grabber is currently not at the top of the list, I need to finish the Delivery Station first: everything is read apart from the four lockers that still needs to be designed. After that, I will continue working on the vacuum grabber. I'll keep you posted. /Hans

    Today, I have added the Mindstorms sensors to read the color: The free wheel mechanism has been improved (made stronger): Now I've just to wait for the missing pieces to finish the supporting structure. Enjoy, Hans

    Since we started in 2011 with our group Sioux.NET on Track, the base functionality has kept the same: visitor of Lego World can choose a color, train is picking up the candy in the desired color and delivers it to the visitor. Choosing the color needs a color selector, which we call the "Physical User Interface" or in short "PUI". In the picture below, you'll find an overview of the PUI's that we build for Lego World 2012 - 2015: For Lego World 2016, we came up with the idea of making a "Wheel of fortune": give the wheel a swing and the color will be the one where the wheel stops. This is how it looks in LDD (Lego Digital Designer): What still needs to be added, is the Mindstorms EV3 with color sensor to read the actual 'selected' color. For the real thing, I still need to order some parts. But you get a good impression what the result will be at the following photo and video: I'll keep you posted. Enjoy, Hans
