Part 3 of building the DIY seismograph. So continuing on the moving arm concept, I settled on using a servo motor as this could easily be driven by the Arduino. I had to make the arm very light so as not to put too much pressure on the small servo motor I was going to use. Here is the model of the arm. Although I went back and forth with different ends to hold the pen, ultimately I ended up going with this clip. Modeled in #freecad #maker #diy #earthquake #arduino #servomotor #seismograph

Part 2. After doing several tests with the read/write head of an old Hard Drive, which was my first idea for moving the pen back and forth, I ultimately abandoned this idea when I just couldn't figure out how to drive it with an Arduino Micro-controller, which I had chosen for this project, so I could learn how to program them. #maker #diy #earthquake #arduino #servomotor #seismograph

Part 1. I can reveal the project I had worked on last month. My nephew messaged me back in early February to ask if I had a dot-matrix printer for his girlfriend's art installation. Seems she wanted to build a DIY seismograph as part of an art exhibit. After getting more info on what she had in mind, in about 10 minutes I had to whole idea flushed out in my head and on a sketchpad. This is the first preliminary Blender render of my idea. #maker #diy #earthquake #arduino #servomotor #seismograph
