    What do you mean with a stopper? Can you be more precise about the video (eg the time frame where you're referring to). And thanks for the compliment.

    Video added with the final flaps and the even smaller wheels. Now working on the casing... (what you see below is just a quick fix to give it an idea how it will look with casing).

    Hahaha ;-). We have all EV3 bricks (total of 18 now) running on the official Lego rechargeable battery (we always bought the EV3 Education set, the battery was then included). And the EV3 is always connected to a transformer, so it won't get out of juice. The only exception is the train, but because the EV3 is not doing that much (only controlling the speed dial), it runs for a long time. And we have enough spares for switching the PF battery.

    Thanks. Hope that we can show our layout at Lego World 2022. Uhm, the third touch sensor ...?
  5. Hanso
    Instead of a color sensor, I have now integrated two touch sensors. This should make the reading of the 'slow down' and 'stop' beacons more reliable. In the video below, you can see a first test run. Outside view (click on the picture to see the full size image); Inside view (click on the picture to see the full size image);

    I have made a even smaller design for the wheels holding the split flaps, this is a rendered image: In total 7 rubber elements (45590) will be inserted in the ring, that creates enough friction to prevent the wheel from slipping. I have ordered the bricks to make the real version (including the bricks needed for the flaps), so I can continue building. When that is finished, I will upload a new video. Update 31-12-2021: Due to the postal delays, the bricks have not yet been delivered. So it will take some time before I can post an update ....

    Thanks! Thanks as well. I have made a render of the wheels and how the flaps are connected to it. I have used different colors to show the different parts, the final wheels will be black. The gap between the two flaps is now +/- 4 mm. This is about the minimum, otherwise the flap cannot rotate. In the inside, you see a tire (44309) and round bricks. The round bricks make sure that the wheel at the other side rotates exactly at the same time. At first, I used the standard rims belonging to the tire and connected the two wheels with an 40L technic axle. Due to the weight, the axle bent so much that it probably would snap after some time. That's why I came up with this 'axle' made of round bricks (6222). The axle made of round bricks (6222) is in the middle connected by the two white bricks (32000).

    In my previous post, I wrote thatn I wanted to minimize the gap between the two flap parts. In order to achieve this, I have create my own wheel that holds the flaps. Additional advantage is that wheel is also smaller than the version with the track elements. The video with the new wheels can be found on Youtube. I will make an LDD sketch of the wheels later this week.

    Updated version: In this version, I have added a touch sensor to detect the 'zero' position. To go to a next number, the wheel is rotated 36 degrees for each next count. The position is reset every time the lever touches the sensor, this prevents drift. The second proof of concept still contains only a large one and two, all the other numbers are not yet ready (not enough bricks ;-)). I have added small numbers on the flaps, so you can see that it works.  At the end of the video, you see a rendered image of how the final flaps will look like. The reason that I have chosen black/red as colors, this is because they are most affordable. For 3 digits, I have to make 30 flaps. That results in a total of 750 flat tiles (3068) PLUS 750 flat tiles inverted (11203). So every cent counts. I don't like the large gap between the two flap-parts, thinking of minimizing that. But have no idea yet how to ... suggestions?
  10. Hanso
    The numbers will look like this (render image): I will use black/red since these bricks are the most cheap to get.
  11. Hanso
    Thanks. Will keep my progress posted in this thread.

    When I was searching for inspiration for my split-flap display, I stumbled across this thread. Great job. My first proof of concept of a split-flap display can be found here, hope you all like this as well (please like the video if you do). The goal is to create a three-digit split flap display for our track. More information about our track can be found here: https://siouxnetontrack.wordpress.com/

    On Wednesday 26 October ("Herfstvakantie Zuid"), Sioux Technologies organizes a 2 hour programming workshop in Eindhoven (NL) for kids in the age of 7 and older. As a tech company, we want to promote technique for children and Lego Spike is a great way to do this. And it is complete free of charge, we will even take care of drinks and food. Please note that the workshop is in Dutch as is the invitation. More information can be found here: https://www.sioux.eu/events/all-events/hot-or-not-the-next-generation-workshop/. You can also use this link for subscribing your kids. Questions? Just leave a message. Looking forward to welcome you and your children at Sioux. Hans Odenthal

    Thanks! Also thanks for the compliment. I haven't been to work because of the lockdown. But earlier, when I was at work I tried to fit it into position. It looked like this: Hope this answers your question. At our blog, you can read more details about building the Lego Container Spiral Storage. https://siouxnetontrack.wordpress.com/2021/02/09/the-container-spiral-storage/ Enjoy reading.
  15. Hanso
    My latest build can be viewed on Youtube, the Container Spiral Storage. Later, I will write an article about this build and the challenges I faced during the construction. This article will be published at our blog: siouxnetontrack.wordpress.com. Some more pictures: Enjoy, Hans
  16. Hanso
    And this is the final result (it took some time due to holidays and ordering the right missing elements): Please like the video if you like what I have build. And some photos from our Flickr page: Enjoy, Hans
  17. Hanso
    Thanks, Mr Jos. Once finished building, it should look something like this (render made with Stud.io):

    Two more videos have been uploaded to our Youtube channel: and the latest version with two doors (final version will have four): Enjoy, Hans

    For delivering the candies to the visitors, we use four lockers. The ticket you have received at the beginning, is used to open the locker containing your own candy. The current version uses an iris-like mechanism, you can see it in the picture (click on it to see it on Youtube in action): I am planning to upgrade the lockers to a new door mechanism, the so called torggler doors. It is named after its inventor Klemens Torggler. Below you find a Youtube video containing the first proof of concept. The mechanism will be improved in the coming weeks. Stay tuned! Enjoy, Hans

    Thanks @Coder Shah and @mic8per

    A new article has been uploaded to our Wordpress blog. We have implemented the daisy chain functionality in our EV3DEV/C++ environment. The good news: it unlocks additional functionality, like more than 4 bricks can be chained, daisy chain using WiFi and accessing the leds and the display on the slave bricks ... The full article can be found here: https://siouxnetontrack.wordpress.com/2020/07/14/our-ev3dev-c-daisy-chain-unlocks-additional-functionality/ And (of course) an example on Youtube: (the USB cable at the master brick is connected to the PC for starting the EV3DEV program with the IP address of the slave)
  22. Hanso
    + Thanks! Your compliments are much appreciated.
  23. Hanso
    Did you know that any standard EV3 brick is capable of controlling the LEDS separately? And that the display is capable of displaying 4 shades of gray? No, this extra functionality is not available via the standard programming environment that Lego provides. But if you use low level programming (I used EV3DEV in combination with C++), you have. See the example below. You can read my article at our blog here: https://siouxnetontrack.wordpress.com/2020/04/25/lego-mindstorms-ev3-with-an-image-with-4-different-shades-of-gray/ Or have a look at the Youtube videos. Enjoy. Hans

    Thanks! I hope we will be at Lego World 2020. Depends if an event as big as Lego World will be allowed again and if we are selected. Hans

    I have drawn the container loader in LDD and then rendered by Studio.io. This is the result: Click on the picture to see it in full resolution (4096 x 2304), more pictures available here: https://flic.kr/s/aHsmMhW4fq. Enjoy, Hans
