The actual informations
Log from Extension card for TDS3000 scopes
Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....

New Boat, New Autopilot - using an old laptop mainboard!
Log from OpenCPN Chart Plotter /w Autopilot and Waypoints
For quite some time I have been thinking about the possibility to using a laptop to run all the heavy OpenPlotter and OpenCPN stuff instead of using a Raspberry Pi. The performance of the RPi is... well it's usable but it's not a pleasant user experience....

Peak Performance Success
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
They say that a picture is worth a thousand words, so: As you can see, THE NEW PEAK DETECT CIRCUIT WORKS! It's always nice to see something work in real life versus simulation. It's kind of hard to see exactly how close the peak detect output...

A Whole Lotta Roots
Log from The Little Green Tower
Just a quick picture to show off the tremendous root growth. The plants are about 5 weeks old except the one on the bottom of the frame which is six weeks old. Click on the picture and zoom in to get a good view of how dense the roots are.You...

Charliefoxtrot with the Embedded Controller
Log from Reverse engineering Toshiba R100 BIOS
Redford did a whole lotta work reverse engineering the BIOS code and figured out that most of the interesting stuff (password check, challenge/response for lost password) is actually done by something off the main x86 processor. We figured out that it's...

Log from ROM Disassembly - AlphaSmart Pro
sub_F374 has caught my interest because it seems to be painting the LCD with the currently selected file's contents according to several state variables that I have not fully reverse-engineered.The routine begins like this:F374 sub_F374: F374 BD F6 18...

Hardware Testing and Web Interface Refinements
Log from The Little Green Tower
I'm currently working on the Python software to interface with the EC/pH/Control board and also developing the web interface. The web interface, shown below, uses webiopi. It's fairly programmer friendly and so far has been reliable. The...

Mass production
Log from Ph0xx
For those wondering how we assembled the boards, we compiled a video of all the different steps. We started off with prototype machinery (Mechatronika M10 and Mechatronika MX70), manual solder paste dispensing using a eC-Stencil-Mate and reflowing...

Firmware Library
Log from USB Type-C Power Delivery Breakout
I'm in the process of porting over the Google Chromium OS code into a standalone library for USB Power Delivery. I started with just the FUSB302-specific code. You find the github repo here. The example explains how to connect this breakout board to...

Update : The plan (First Iteration)
Log from CloverDroid : A Smart Urban Farm
Here is the plan. I plan to turn this into this And here is the design block diagram. There will be 3 sensor node and a nutrient control system. All of them is developed with ESP8266 board (either WeMos D1 mini or NodeMCU). I plan to use Blynk IoT...

More SD Card Write Details
Log from 3-Chip Z80 Design
Had to dig into the FPGA code for the SD card. Using Neal Crook's documentation of Grant Searle's version (longer pedigree on the page). The status register values are: // SD_Status bit values from Neal Crook's documentation of Grant's SD card // b7...

Updates
Log from Latitude E6400 Coreboot port
It's been nearly 2 years since my last log, and things are quite different from where I left it. I've been poking around at this project in between other projects and university, so most of these details are not recent. I found out that there has since...

Temperature sensors
Log from UltraTower
Temperature is important in soilless cultivation. Articles agree on an ideal growing temperature between 18°C and 26°C. A too cold temperature will slow down growth but increase the dissolved oxygen in the water. While too hot temperature will...
