This is going to become the world’s smallest direct drive turntable! USB-powered and driven by a stepper motor at very low torque (low noise), it will be completely made with a 3D printer and also include a class D power amplifier (headphones & loudspeakers). Of course, it is running my MagicQuartz software. Stay tuned for updates! 🙂
I’m getting melancholic – so much has happened since then! (But the design with the two transistors (and nothing more) was actually quite nice, it generated a stable rectangular signal … 🙂 )
I have updated the instructions for building the free
Arduino version. Enjoy! (But be careful … High Voltage!)
OK, the transformer is not yet fully mounted and there are still some design issues with the 3D printed plastic parts. But all in all, it’s done.
Also note the 3D-printed compartment for the red filter capacitor (just behind the display). This has to be secured because it’s the really dangerous part (high voltage!).
Last Friday, the 3D printer arrived. I’m planning to offer 3D-printed case parts to simplify assembly. They are optional, but highly recommended: you don’t have to drill and cut out all the holes.
Yes, I finally managed to upload the Arduino version. And the very comprehensive documentation, of course … If you come across any errors, please do not hesitate to contact me! 🙂
This video (taken in September 2014) demontrates the capabilities of the almost finished MagicQuartz.
here’s the new homepage. As the MagicQuartz is reaching its final devloment state, I thought it would be a good idea to create a better looking homepage.
