20230214a -- Memory, cont.
Log from ROM Disassembly - AlphaSmart Pro
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...

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...

20230221b -- File Inserting
Log from ROM Disassembly - AlphaSmart Pro
Intrigued by the various file-related pointers seen in deleteThisFile_EB9B, I remember that the keyboard scan routine had a final case where the bulk of the keystrokes (the printable ones) are handled, and there was a scan code to ASCII routine before...

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......

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...

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...

Comm protocol between camera and drone controller
Log from Reverse Engineering a ProMark VR Toy Drone
Initially I thought the data stream from the camera board to the quadcopter controller was PPM. This signal is only active when the app is running and the on-screen controls are brought up. The quadcopter has to be power-cycled in order to be controlled...

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...

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...

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...

Quick Update 22/09/22
Log from UltraTower
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...
