EC Sensor
Log from UltraTower
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
Log from Reverse engineering Toshiba R100 BIOS
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...

EC or not EC: that is the question
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
For some reason, EC probes are relatively expensive. In most cases they are more expensive than pH probes, which to me seem a lot harder to make. So, I decided to make my own EC probe, as you can see below:The contacts are gold plated Studex ear piercing...

Three Dollar EC - PPM Meter [Arduino]
Log from Hacking the way to growing food
This Blog will Cover How to build a cheap EC meter for your aquaponics/Hydroponics or water quality related projects. We are not going to get into what the ideal value of PPM or EC is, Just cover how to measure and quantify a fluid.We will be using this...

Update Code For Three Dollar EC PPM Meter for MCU [Arduino]
Log from Hacking the way to growing food
This code is a slight update of the last one, updated:>Better Uptime Counter>LCD Shield>New Pin out Diagram>Restart Protected Calibration Details>EU and US Plug Calibrated Probe Also a quick update to the code so the calibration value will survive a...

September 28th 2023: I can't make the linear actuator move precisely
Log from Automatic Moving Cricket Wicket
It was dumb to use a DC motor for this project. I should have just ponied up the resources for a high speed stepper. My plan was to attach a rotary encoder to the DC motor to accurately measure the number of rotations. This is not easy....First, I tried...

The Keyboard
Log from Anatomy of a Philips VideoWRITER
Before I start this log on the keyboard I should mention that I'm in the process of putting all of my writings and software on the Video Writer on a small website. The following is an almost direct copy of what will be the article about the keyboard......

Plasma Effect for TMS9918
Log from Game Boards for RC2014
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...

Interfacing ternary and binary components
Log from Homebrew ternary computer
Ok, now it is kind of proven that binary CPLD (or FPGA) may implement ternary logic, but how we can integrate it with "true" ternary components, especially when CPLD is 3.3V and TRIMUXes are -5V and +5V? Answer is DG403 chips may do the job: Because...

Self Optimising Automated Arduino Nutrient Doser
Log from Hacking the way to growing food
This Blog is about making a nutrient dosing system for hydroponics that is plug and play, I didnt quite get it to the full stage of plug and play with this version. But it is almost there. Because the change of nutrient strength of our systems can be...

Peak Performance
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
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...
