Multiple 3D print new marble run module
Verfasst: 21 Nov 2019, 17:46
I made a new module for my big marble run. It's a double chain unit with super fast descent inside the 3D blocks. Because you can hardly see the marbles descending due to the limited opening between the blocks, a neopixel led string module has been added. Once the marbles are upstairs, they go down very quickly internally in hollow blocks. There's a pipe in the blocks where the marbles can run. The marbles are brought up by means of magnetic blocks on a long chain. Because you can't see the marbles descending in the blocks themselves, I've added 14 neo leds per side that indicate the place where the marble is descending. In turn, the colour is also altered so that you can see when there is more than one marble in the descent. The TXT-Controller controls everything and counts how many marbles go in and out. If you stop, both counters have to be the same after a while, otherwise a marble would be missing somewhere. All this is done via the TXT-Controller.
But the TXT-Controller can't easily control the speed of a neo led string. I'll use this function in my familiar FPGA module. I use in parallel the IR detector signals that are present at the top of the chain. When a marble descends, you can see this through the neo leds.
I've created quite a lot of new 3D parts. These can be found on Thingiverse:

A lot of pictures can be seen on my Flickr web.
I made a short video of the new module.
