The Universal Interface

It’s time to present a relatively simple yet useful device: the Universal Interface. The need for this little helper arised when building the control for my CNC milling machine. But that’s a major project that I will introduce another time. Today it’s only about this little board.

Variable-Frequency Drive

This post ist about the CNC conversion of a manual dividing head aka indexing head. If you’re not familiar with that kind of equipment, there’s a wiki page here. One makes use of interchangeable indexing plates and and the internal worm gear to accurately divide the circle. Parts like cogwheels and the like can be machined this way. A video of the finished project can be found here on my youtube cannel.

If you’ve read through my previous posts of this series you know that here is an Arduino and two home-made PCBs together with 4 transducers waiting to work together as an ultrasonic wind meter. If you haven’t you may click here for an overview of posts on my anemometer project: /projects/arduino-ultrasonic-anemometer//posts/arduino-ultrasonic-anemometer-part-6-mechanical-design/
