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...

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...

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 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...

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....

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...

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...
