I just have to show you my newest DIY turntable gear (I hope this is OK!?
First out is a RPM speed check gadget that will help turntable owners to tune their TT's to the correct speed.
This gadget can be built for abut 10 buck!
Case is 3D printed and the tachometer is Arduino powered.
Next one is a Tone ARM this project is also realized with the help of a 3D printer.
