Amazing project! I've been looking for something like this for decades really! I'll try to adapt this project to my tape decks, turning them to direct drive. Nowadays I have lots of problems with belts, the quality and durability are very low. Thanks a lot for sharing!
Very kööl!!! I am currently using SimpleFOC with excellent results and it's great to see more options for speed control of turntables! Well done and congrats.
Hi, this probably won't work as MagicQuartz only works with conventional AC motors, but your Kenwood uses a direct drive. I would definitely try to repair the original controller of the Kenwood, this beautiful device deserves it! Good luck!!!
Wow! New update after 13 years! If any hardware part is required, we'd love to sponsor related prototype services, covering custom PCBs, 3DP, CNC machining etc. (PCBWay zoey)
Hi! It also works with 230V. Regarding availability: I do not sell anything at the moment. You'd have to build the device yourself. Everything is available and free. Please see my homepage for details (linked in the video description).
Great idea, especially to insulate the AC motor from a noisy VFD by a transformer. And a low power VFD too. But my association, vynil is something about oldstyle visual design. LED 7-segment voltmeter is offstyle, nixies freq meter is better. And LCD is like geek addition, can be covered while usage. Or even move to quality graphic OLED display to be universal. Mega2560 vs RP2040.
Absolutely right! But remember that this thing was designed to use readily available parts. Of course, everything can be replaced. An OLED display should work. The voltmeter could be replaced with an analog one, and maybe a tongue frequency meter would be fun too ... In a future version I would like to implement a completely "headless" automatic mode. Then you don't need a display at all. And yes, eventually the firmware will be migrated to another platform. The AVRs are already quite old and also getting more and more expensive ... Thanks for your feedback!
Hi, this is not currently sold as a finished product, but is available as a DIY project. Everything is currently available for free (in particular the firmware).
@@DddNnn-r2y I'm not selling anything at the moment. You'd have to source the parts yourself, but that's easy. I've made everything as accessible as possible. Please see my homepage and the GitHub repo (see links in the video description).
Hi! Leider habe ich das Magic77-Projekt seit etwa 2010 nicht weiterverfolgt. Vielleicht sollte ich das bei Gelegenheit mal machen ... das war eigentlich ein "cooles" Projekt. Dank neuer Techniken (3D-Druck, Arduino, usw.) sollte das heute auch viel effizienter umzusetzen sein.

Thanks, and thanks for mentioning SimpleFOC! That seems like a very nice option for direct drive turntables!
I watched your video today. I have a vintage Kenwood KP-9010 DD turntable with a dead control system and your MagicQuartz may save it!

I have replaced all caps and most of the ics with no luck

I am writing from Delhi, India. We have 230volts here. Is your product as shown in video is available for sale. If yes, please provide details. Thanks

Please let me know when you're ready to make and sell these
How much are they? Where can I buy one?

@@RealCyberSeb where do I get the diy kit?
