  • 1958 Turntable from the Black Forest - 10: SMD Time - Solder the IR Speed Sensor PCB

    In post 6 I made a breadboard prototype of the speed signal circuit. I made a KiCAD layout and sent my fab files to oshpark.com . My PCBs arrived yesterday. This is the story of the build and test. Let's start with a short recap of the sensor schematic…

  • 1958 Turntable from the Black Forest - 8: Digital Light Organ Enchantment

    We're entering a new chapter for the Perpetuum-Ebner turntable. The practical things are sorted out and the once defect table spins again. Time for some enchantment. I'm going to build a light organ. Digital Light Organ There are a number of projects…

  • 1958 Turntable from the Black Forest - 7: Control Theory - End of Chapter 1

    The first chapter is finished. I started with a defect turntable. It looked good at the start but didn't turn. It hasn't changed on the outside, but the inside is revamped with latest technology. And it spins! In each of the previous 6 posts I have touched…

  • 1958 Turntable from the Black Forest - 6: Turntable Speed Sensor design

    The basis for my turntable enchantment is almost done. I'm very close to having a working turntable. Let's have a look at the speed sensor circuit today. One of the very last things to complete for this basis part. The Speed Sensor The sensor is an infrared…

  • 1958 Turntable from the Black Forest - 5: Turntable speed sample testbed with Arduino UNO

    I'm creating a test setup for the speed sample firmware. In this post I'm reviewing the speed sensing approach and how the Arduino knows how fast the turntable is spinning. Where should I measure the speed? There are a number of options. The table has…
