  • Lucky 4D Printer

  • The JP-QR701 specifications indicate that it has GB2312 support. I think this also applies to similar products that all seem to come from the same OEM or at least from the same design. Most documentation - especially that found on English-language distributors...
  • Peak Performance

  • Below is a picture of a patch that gates the input to the ADC so that it is only looking at the value from the EC probe at the end of the square wave pulse, after the initial transient has settled out. It works really well, dutifully recording the voltage...
  • All boards received

  • The rest of the boards just came:I think I will connect them together through wire-wrapped "motherboard" (lets call it "NEDONAND-10" ; )All of these NEDONAND components could be tested one by one using PIC microcontroller (connected to PC through RS-232)...
  • Z80 (CP/M) Writing to SD Card

  • Digging into SD card writes means shifting gears from the Boot BIOS source code since the Boot BIOS code only does reads. The CP/M BIOS code (CBIOS128.LST) which does the reads/writes after booting. Here's the BIOS code for writes to the SD Card: 0754...
  • 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...

  • 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...
