Today I have made a new module, a worm screw with XS-motor drive and dual input-output. Here the steel balls can be used as storage but the children can also take them out to place further in the process. This makes it more interactive. There are 2 inputs and 2 outputs. If the children do not take a...

Ich finde Kugelbahnen super! Welcher Baukasten von fischertechnik is denn der beste (Lidl,Real)? I live in Belgium, Fischertechnik Lidl sets are not available here. I always buy the Fischertechnik Dynamic XL boxes 524327. For me, this has the best price ratio. There are a lot of pieces in the box (...

Thanks PHabermehl, Today another module is added to my project, a big waterfall with 5 levels and neodymium magnets for the hall detectors. https://farm5.staticflickr.com/4736/27402081439_8fff5771d2_o.jpg https://farm5.staticflickr.com/4735/39178771251_1bf874d241_o.jpg https://farm5.staticflickr.com...

Thanks Kilian! Here is another small module to move the steel balls to the left or to the right via a small servo. The grandchildren can make the choice via a button on their control panel. I use several of these controlled modules in the project. This will become clearer later when I make a video o...

Today I have tested an escalator module with fischertechnik parts. This brings the steel balls back up again. The chain contains 200 chain parts and 40 black blocks 15mm (black block model from 1980). https://farm5.staticflickr.com/4690/27354426249_8cf9a9e889_o.jpg There is also a small joystick mad...

Hi Christian, Hi Frans, The combination of an FPGA with fischertechnik is new at least for me. How is your development including validation approach and programming environment? The basis is a FPGA module from Terasic the "DE0-Nano board" This module is ready for use, if you make a carrier print for...

The movable rail on the worm gear, great idea! Thanks! There are many other modules but they are not yet visible on the photo. Currently I have too few inputs for the detectors. That is why I now design 2 extra PCBs each with 40 inputs extra . I still had to make a separate control panel for the ch...

This development has been going on for a year now. The first half year it was mainly the development of the controller that asked the most time. I need about 100 I / O lines for the entire design. That is why I opted for a DIY controller together with an FPGA module. With an FPGA you can assign any ...

Today I have adapted some FT 37468 blocks to fit a ball bearing D8xd4x3 mm. The steel shafts turn smoother with this bearing. I also mounted some neodymium magnets in the FT-37468 blocks. These are used as limit switches. https://farm5.staticflickr.com/4546/38849934741_b13b71e6af_h.jpg The blocks we...

Thanks Peter! Today I made a distribution module for the steel balls. This module determines how many steel balls must be forwarded to other modules. I have placed 6 neodymium magnets for position determination. At the top there must be a reflection detector to count the correct number of steel ball...

Well, you still miss a small detail: https://farm5.staticflickr.com/4583/38602578412_e56260d64c_o.jpg The clip 5, FT-37679 is mounted on the 4 mm shafts between the plexi plates. That clip is not completely round, there is a slit. During the assembly of all axes you can decide how this clip will be ...

Thanks Thomas for the translation. I did not know the name of "a driven Galton board". 60 years ago I saw such an board at the fun fair. I now wanted to recreate those with Fischertechnik parts but with the addition of an interactive element. The grandchildren are too young to build it (3 and 5 year...

I have been working for a year on a huge marble run. Many modules have already been completed. I use 4x Dynamic XL, 4X Creatieve box 1000, 4x Dynamic tunning set, powerset, XM motors etc. Most of the photos are on my Flickr: http://www.flickr.com/photos/fotoopa_hs/ I just made a new module, a pyrami...

I use unipolar hall detectors for my "Kugelban project" to read input information. Now I come to the discovery that the magnets of the FI-119850 blocks are not all mounted in the same way. The north and south poles of the magnets are sometimes swapped. Because I use unipolar detectors, they do not w...
