  • Progress on the EC

  • Some progress has been made the past few days on the actual Renesas EC chip. A detailed log will probably follow in the upcoming few days, once I get the chance to take a few pictures and screenshots.In 2014 I etched a PCB to mount the EC on after desoldering...
  • 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...

  • EC firmware dumped

  • After another long hiatus, I've come back to this project. Let's break this thing!I've etched a new board that lets me access important pins (serial TX, RX, CLK, BUSY ; RST and power lines) without having to fiddle with the previous hacky breakout board.I've...
  • 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...

  • Plasma Effect for TMS9918

  • Plascii Petsma by Cruzer/Camelot has one of the nicest looking plasma effects I've seen for the C64. Since he included the source code, I was able to port it to the Z80 and TMS9918.    On top of the features in the original C64 version, I have...
  • 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...
  • 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...

  • 20230214a -- Memory, cont.

  • Operating under the current assumption that RAM is 32 KiB banked at address 0000-7fff, with the first 256 bytes masked off by special function registers and internal SRAM, some other code sections of interest were found.  E.g.:ED00 loc_ED00: ED00...
