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...

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...

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...

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...

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...

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...

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...

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...

Log from 1802 MemberChip Card
Here are some "Quickstart" instructions for the Menu, BASIC, VTL2, and Visual/02 programs in Mike Riley's alternate program ROM. They're not a full manual yet, but will get you started and give you a "taste" of vintage programs and languages. A Quickstart...

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...

Cyrillic alphabets in Terminal-BASIC output
Log from Terminal-BASIC
My friend Dylan Brophy inspired me to investigate the ability to output the cyrillic text using different output devices, supported by Terminal-BASIC. 1. Using symbols others then capital latin in identifiers not possible and unnecessary. 2. USART output....
