Log from Multi-Function Selective Firing Neurons
As for the equation that will be used to determine whether a neurotransmitter triggers one of the intervals in a neuron, it will be as follows:where the numerator represents the sum of the specific neurotransmitter (t) from the neurons that are active...

Reverse Engineering from Package Data
Log from Reverse Engineering a Drone
As you can see airodump-ng picked up the WiFi of the drone and also that it is running on channel 2. Next I recorded some packages. sudo airodump-ng -w JJRC_out -c 2 -bssid 10:A4:BE:2E:77:B5 wlan0mon While recording I simply used all the functions the...

Recovering the symbol table
Log from Android offline speech recognition natively on PC
One last thing that was still missing was the symbol table. Apparently the output of the softmax layer maps directly to the symbol table, and since this output is 128 in length, I was searching for a table of this same length.The prime suspect was of...

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...

What
Log from Reverse-Engineering a low-cost USB CO₂ monitor
In past projects I've had raging successes by just looking at the raw data, XORing stuff together, and maybe squinting my eyes a little. Spoiler: Not so this time. I'll walk you through the steps anyway.---------- more ----------What we know: Data comes...

Analogue Wind Vane With Auto Set Up
Log from Arduino GPRS IOT Weather Station
As the amazing online GPRS Weather Station project continues, we have yet another upgrade to the vast array of sensors with a professional analogue wind vane, kindly donated by Vector Instruments. This device will eventually be hooked into the new, upgraded,...

Z80 (CP/M) Writing to SD Card
Log from 3-Chip Z80 Design
Digging into SD card writes means shifting gears from the Boot BIOS source code since the Boot BIOS code only does reads. The CP/M BIOS code (CBIOS128.LST) which does the reads/writes after booting. Here's the BIOS code for writes to the SD Card: 0754...

Characterizing the Buck Converter
Log from Solar MPPT Charger for 24/7 "IOT" devices
First up, the latest revision. Small changes from the last version including tightening up various current loops in the buck converter and moving the battery-side transient TVS diode to the anode side of the reverse-polarity protection diode to...

20230222b A Tale of Two Translations
Log from ROM Disassembly - AlphaSmart Pro
There are several translation routines found during the file sending stuff that translate one character value into another one. Some we understand, like this one:F4DC sub_F4DC: F4DC 84 7F anda #$7F ; reset high bit F4DE 16 tab F4DF 4F clra F4E0...

Initial work
Log from I2C interfacing UMFT4222EV module
2020-11-16 Downloaded libft4222-linux-1.4.4.9.tgz and unzipped it. Ran the command: sudo ./install4222.sh and got no complaints. In the examples/get-version.c file, there are instructions for Linux: cc get-version.c -lft4222 -Wl,-rpath,/usr/local/lib...

Eureka!
Log from Commodore CHESSmate Reproduction
After I convinced myself that the emulator was probably OK, I turned back to the ROM. But after I found yet another ROM image online, and it turned out to be identical to the other three, I have to rule out bad ROM as well. Just as well as I was...

SATA, DDR3, Verilog Visualizer and Other Stuff
Log from Nysa: FPGA Development Environment
SATA StatusAfter weeks of painful debugging. I have been able to read and write to the hard drive!I ran into an issue though... the speed at which I can communicate with my FPGA to/from my computer maxes out at about 16MBs and the hard drive reads/writes...

Space doesn't stretch forever in all directions...
Log from 1Keyer
One of the goals of this project is to make the code capable of being entered into the Hackaday 1K code competition. This isn't perhaps as easy as it sounds: 1K is not a lot of memory, and the Arduino framework (as generally friendly as it is) isn't...

Topology (1)
Log from Programmable Precision Resistor
In this post I want to share how I selected a suitable topology for the resistor network that will be the core of the programmable decade resistor. Although I did some online “research”, the following criteria determined my choices: Switch...
