  • Solar Water Heating Controller

  • An unexpected cold shower made it clear that I need a new controller for our solar warm water heating system ("split architecture" which is typical for installation in middle and northern Europe - thanks @Saabman for helping me understand that I had...
  • 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. 
  • Quick Update 22/09/22

  • The new tower and the pcb are being tested for 2 weeks now. Everything is working great. On the picture you can see a 3 weeks old basil plant, with 2 weeks in the tower. You can also see the fog coming out of the tower. The roots are growing and are...

  • Hydroponics Nutrient feeder unit

  • I have been growing leafy greens using Hydroponics for the last 3 years. I was tiered checking out for the nutrient levels and pH level of the nutrient water solution, so I decided to make a nutrient feeding unit to maintain the optimal nutrient level...
  • I added the Tindie logo

  • At the OHSummit, I was joined by Amber Cunningham, community manager of Tindie. While Hackaday and Tindie have the same overlords ruling over them, we can't really have Amber going around with a Hackaday logo on her badge, can we?...So I spent 15 minutes...
  • EC Sensor

  • EC is the abbreviation for Electro Conductivity. It is used to determine the nutrient concentration of the solution. This factor is essential to optimize the soilless culture. Indeed, the nutrient concentration will not be the same for a seeding as for...

  • Could this work?

  • I recovered the project file from my drive and made some changes to it. The question is, which wire goes where? I won't know for sure until the dummy plug arrives, but the AUX line is definitely used for this purpose. I even created an EDID data for...
  • aquaPionics

  • An Open Source Aquaponics Control System with sensors galore and control of the water valve. With a dashboard, data-logging and alerts too!

  • Improvement of the EC sensor

  • It is better to read the EC sensor log before reading this one. I wanted to test the stability and accuracy of the EC sensor! So I replaced the EC probe with a fixed resistor (to mimic the resistance of a solution).   The EC probe was replaced...
