Beautiful build from tinker log. Check out more info here.
I always loved watching marble machines, especially the creations of denha. These little machines are super cute and very well made. So a marble machine was on my todo list for a very long time.
To start easy, I decided to build the most minimalistic marble machine I could think of. Just one oval and a single lift mechanism.
To form the oval tracks out of 2mm brass I bend them in a bending jig and pressed them into a template, milled on my ShapeOko. The support posts where also cut on my CNC out of 2mm brass sheet.
After soldering the support posts to the rails and soldering the lifting mechanism, everything got test assembled on a piece of MDF.
Of course, such a marble machine needs a nice base. To find a nice piece of wood I spent a couple of hours at a wood shop for local and exotic woods. I bought a piece of african padouk. That piece then got cut to length, sanded (a lot!) and finished with linseed oil.
Finally, putting all together, it needed quite some tweaking to get it robust and not losing a ball every now and then. The balls are 15mm in diameter and made out of stainless steel.
This was the first time I worked with wood and brass. Always good to increase the possible materials. I enjoyed working with wood, despite the mess that is makes in my small workshop.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
