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...

Simple Command Driven Interface
Log from Not Quite Useless Raspberry Pi Replacement
Wrote a very basic command interface with three commands:W - Write the EEPROMR - Read the EEPROMB - Bounce an LED across the RPP-UIO-16 cardThe result looks like this:Write to the EEPROM Read from the EEPROM 0000 00 01 02 03 04 05 06 07 08 09 0a 0b 0c...

Building an EC sensor.
Log from Autodro
The end goal for the Autodro is a complete monitoring system for under $10. This means that cheaper, simpler, less accurate sensors are needed. I've started with a simple EC sensor, and am hoping to design something around $1.So far, I've created a sensor...

Gathering information
Log from WD2002SJ Bench Power Supply
Tonight I gathered some reference/research material for this project. Fortunately, several others have done some really great work with this module, so here's credit to them: LTC3780 DatasheetBeyond Logic blog postTemplaro blog postGreat Scott videoJulien...

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...

pH and EC Circuits Tested
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
I just got the pH portion of the circuit working. There actually wasn't anything wrong with the circuit. It turns out that the probe that I was initially was using was bad. I tried a different brand and it worked perfectly. The working probe is listed...

Improvement of the EC sensor
Log from UltraTower
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...

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...

First attempts at understanding how the video link works
Log from Controlling a JJRC H37 Elfie quad from a PC
I haven't done any further tests with the UDP controls, but I captured some more traffic in order to try to figure out how is the video transmitted between the quadcopter and the mobile phone. The communication seems to be established through port 8888...

When entering a short test sequence on my remote this is what my receiver displays (a dot means an exact repetition of the previous packet):All on: 07 B0 F2 EA 35 90 01 B9 AC F9 .......................... 07 B0 F2 EA 35 90 00 B9 74 E0 .. Color red: 07...

Access SD Cards from the PSoC
Log from 3-Chip Z80 Design
I'm going to create a stand-alone PSoC project to use the PSoC to read SD cards. I'm going to start with the hardware defines for this project (which should leave the Z80 hardware pins unmolested) and just not download code. For the software piece, I...

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...

ALU and Instruction Set
Log from Novasaur CP/M TTL Retrocomputer
Hardware testing is complete on all the jump and branch instructions. So that's the first 8 out of 256 instructions tested! The next 24 are loading operands. These should work fine since the jump/branch instructions are also loading operands in order...
