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...

Re Openings
Log from Commodore CHESSmate Reproduction
In a previous log I said, "I'm not going to overthink this. Random selection from the chess openings is working.". Well I lied. I am going to overthink this. (Well at least think it.) Something I should have done when working on the opening moves was...

Solar Water Heating Controller
Details from Solar Water Heating Controller
An unexpected cold shower made it clear that I need a new controller for our solar warm water heating system ("split architecture" which is typical for installation in middle and northern Europe - thanks @Saabman for helping me understand that I had...

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...

Different SD card MBR formats
Log from OSI SD Card Operating System (OSISDOS)
I tried a couple of other cards and found that they have different MBR formats with no header. I noted this in a previous log. There's an offset at 0x01BE that points to the MBR. My theory is this is true for "bigger" cards. I think the reason I could...

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...

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...

Delta coding and some stats
Log from PEAC Pisano with End-Around Carry algorithm
With the new harvest, I estimate that the perfect and maximal orbits under m=1M is around 100K. This starts to make quite a large .h file to include in the sieve generator. Not that it's such a concern but scalability, you know.... And embedding such...

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...
