![]() ![]() To drive the 28byj-48 stepper motor with a constant speed I've used an Arduino Uno with the AccelStepper library. They all should go smoothly and leave the rails Lastly, to test them all at once put 11 balls on the hour and 15min rails and 4 balls on the 5 min rail. wherever you glued the connector on the 15min rail you can glue it on the same place on the hour rail. When the 12th ball arrives it should tip over. again it shouldn't tip over while 11 balls are on it. When you're satisfied go to the 15min rail. It should tip over when the 5th ball comes. And position the connector piece accordingly so it doesn't tip over. You have to figure out the center of gravity and glue it when you are certain. The rails and the connectors under them are not attached. This way everyone can adjust them to their needs. ![]() I did not design the rail pieces connected to the joints. This is the most important part of this project. I tweaked and re-designed this to create an elevator mechanism. User mgg942 used this design and created a rotary to linear drive on Thingiverse. The elevator design was inspired by this mechanism. But the dimensions are different due to different ball sizes and weight distribution. The rails were inspired by the original rolling ball clock. The rods(8mmx8mm) were designed to be sturdy. The base structure is basically 6 rails holding 4 rods. I suggest you to read this step after you've seen the tutorials.ĭetails on the design process are noted on the images. Īlso, this youtube series gives a good beginner tutorial: If you are new to the Fusion 360 environment I suggest you take a look at a few tutorials. It gives an insight on how the ball rails were designed in Fusion 360. This step is for people who want to design their own ball clocks or want to add new features to this project. You can skip this step if you just want to print the project. I strongly encourage you to share your build when it's done! This way you can change the design to your own liking and then glue them together. Many parts I've designed are not connected. I'll show you the way I built this project and provide you with open-ended questions, so you can add your own ideas, and take this project even further. The purpose of this instructable is not just to give you a cookbook. So, if you encounter any problems during your build you can solve them easily. After giving you a step by step assembly guide and show you how to sync your clock, I'll end the instructable with a troubleshooting guide. I'll give you a 3d print guide so you can easily print the required pieces and arrange them. Then I will give you an insight into the design process of this clock, so you'll be able to design your own clock. Next, I will explain the Idea behind this project. In the first step, I will give you a little bit of history of rolling ball clocks and ball clocks in general. The 60-minute rail with 5-minute intervals.The 5-minute rail with 1-minute intervals.Marble Clock is a 3D printed rolling ball clock that tells the time by the location of marbles/balls. I think this will eliminate many problems of the project before it's published. You can follow me and give feedback on my projects. 6.I have a twitter account where I share the progress of my projects before I publish them. Have at least one clean cut modern material design instead of the 1800 century ornamental lavish curve design, to make it more viewable. Focus on making this live up to the promoted 3D instead of working on getting other cash revenue apps. The idea is great, I imagine it is challenging to let us see inside and turn around as been commented eloquently by others but we expected to see inside the gears, going in deeper into layers zooming and turning in different directions. ![]() Hard to tell time - why do you, the developer only respond to favorable ratings there have been so many calls to make it easier to tell time but you don’t act on this simple fix make the arms more visible, the red ends someone asked for eight years ago is not sufficient. It is not 3 Dimensional, deceiving referencing 3D. You did a nice job w the inside gear movement that can be seen move a bit as your picture shows, but 1. What is seen is nice, but not as promoted ![]()
