  • Some notes

  • The ESP-32 board pins operate in 3.3v levels while the Gravity pH and EC sensors operate in 5V. I inserted a simple voltage divider to shift 5v to 3.3v levels on the signal pins. 
  • Step 1: 3D printing

  • To build a tower you will need to print the 3D parts shown on the left of the image. The "Sensors float" part is optional, print it if you want to use the pH and EC sensors. You will need 12 times the part: "Basket".  You can download the files...

  • Fan controller for Re:Load Pro

  • Make you the PCB and get the components and any standard 60mm 4-wire fan will probably do the job. I used a JMC "6015-12HB APW" that I had lying around. The exact the same fan is readily available on eBay.I used eagle to design my PCB, and the files...
  • Cree Dimming Level

  • Flash the Arduino with the following sketch. This is also included as a file attached to the project. int last_level = 0; bool last_state = false; bool stable = false; int count = 0; const int cutoffs[198] = {/* 1*/ 833, 831, /* 2*/ 825, 823, /* 3*/...
  • Make 20 vactrols

  • In order to control the video effects via MIDI, I needed a part that could override the potentiometers. For full effects, I need less than 30 ohms, to switch an effect off completely, a resistance of more than a few kohms would be desirable. I couldn't...
  • Understanding how to disconnect the speaker

  • moThe big black device in the middle of the printed circuit board (PCB) is the speaker (aka buzzer, or transducer). You can see a little slit in the one side where the sound comes out. There is a back side to the circuit board that you cannot easily...
