In The Digital Domain
Log from Reverse-Engineering the milight on-air protocol
I also wanted to sniff the communication between the micro controller and radio IC, but couldn't get the case of the remote control open. At the next opportunity I brought the Mi-Light Wi-Fi controller with me and got that open more or less easily:Inside...

Designing the custom LCD
Log from Fluke 8060a Custom LCD
Dave at eevblog posted an excellent video series on designing custom LCDs, so I watched those a number of times. I also found another eevblog user who posted a great writeup of a replacement LCD he designed for his Tandy/Radio Shack TRS-80...

Rev1 Voltage Test
Log from Multimeter
I did another test with the rev1 prototype, this time only measuring voltage, and bringing it all the way to the maximum voltage of 60V. Again I am doing calibration and comparison to my Fluke 101 Multimeter. This has a problem as the Fluke 101 does...

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...

Interfacing ternary and binary components
Log from Homebrew ternary computer
Ok, now it is kind of proven that binary CPLD (or FPGA) may implement ternary logic, but how we can integrate it with "true" ternary components, especially when CPLD is 3.3V and TRIMUXes are -5V and +5V? Answer is DG403 chips may do the job: Because...

How Does KGE Work? (With Example) (OLD/OUTDATED)
Log from KGE (Kinda Good Encryption)
This is an overview of the layout in which KGE works. Get User String (Round 0)Split String Into PairsIf Not Enough Then Add Specially Made Character Which Is Deleted During DecryptionUse Byte SubstitutionSwitch User Strings To IDs and Find Replacement...

3. Fundamentals of Hexapod Robot
Log from Hexapod Modelling, Path Planning and Control
In this chapter, the fundamental concepts of hexapod robots such as walking gaits, stability, kinematics and dynamics are covered which are essential to obtain a better understanding of the control architecture that is delivered in the next chapter....

20230225a - Displaying the Current File
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...

Debugging
Log from 8 Bit TTA Interpreter
Debugging Need to get this project working. One problem is that the Nano does not have enough pins. So I have used a Meduino (a Mega2560 Pro Mini). Here is the schematic: Here is the PCB: The ports (P1 & P2) match the TTA8 bus. A problem with the Meduino...

ROM checksum code
Log from Re-UD-80 - a larger display for Epson PX-4 / PX-8
The 5.21E ROM works file with the current board, but the 7.11A ROM uses a different pin for the vertical sync signal. This can be fixed, but then the 5.21E ROM results in no display. Rather than fixing the hardware (with a jumper to be changed when the...

muahaha, I cheated :)
Log from Game Boy Cartridge plus Programmer
So since the Teensy++ 2.0 bootloader is not available and I'm not feeling comfortable to learn all the bells and whistles of USB communications I was looking for other options. Googling "at90usb1287 arduino" I found this https://github.com/mattairtech/ArduinoCore-avr...

Micro-coded controller deep-dive
Log from Custom circuit testing using Intel HEX files
In this project, instead of using a standard embedded processor and programming it to execute 3 tasks at hand (parsing HEX character stream, generating HEX character stream, and writing character stream to video RAM driving VGA), I created 3 independent...

We Have Blinkenlights!
Log from 2:5 Scale KENBAK-1 Personal Computer Reproduction
With the wiring complete I wrote a small program in Python to test the lights, buttons, and switches on the front panel. To be clear this is NOT the KENBAK-2/5 emulator running a program (yet). As it turns out I did have to replace one of the LEDs...
