Project Resumption
Log from Raspberry Pi Head Unit
I'm going to eb hopefully getting my teeth back into this project after a while on the shelf.One thing I was dubious on was how to handle the shutting down of the Pi safely when the car is switched off without causing corruption in the filesystem.One...

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...

The SGT1 address multiplexer analysis
Log from STEbus 6845/6803 video board
The 4-to-1 bit multiplexers select input bits based on signals B and A. "B" is VCYC inverted. "A", the Row/Column selector, is /RAS clocked by the 28 MHz master clock. This is /RAS delayed by 1/28th of a microsecond, which is 35 ns. /CAS is /RAS clocked...

What shall we wrap it all up in?
Log from Commercial home automation
Any enclosure needs to be easy to access yet provide enough space to get all of our cables in and out without being too big. A tough challenge!---------- more ----------Once our technology solution is chosen, we have to mount it, cable it, make it all...

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...

V9958 - Beyond Hello World
Log from rosco_m68k
Development on the V9958 board continues apace, and after a false start due to a silly mistake in the first revision things are back on-track with a revision 1 prototype. The design is now validated and working really well. So far it's baby-steps in...

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...

20230219b -- Actual File Sending
Log from ROM Disassembly - AlphaSmart Pro
Having found the send speed setting, I got a bit interested in the file sending process itself. Tracing back a reference to "Sending....Press any key to stop. " text, I find sub_F013:F013 ; XXX prepare to send (flags and prompt) F013 sub_F013:...

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...

Programming Toolchain
Log from MIKBUG on Multicomp
There are some options for assembling 6800 code today. Ideally, a cross assembler would be good from Windows. Herb Johnson has adapted William C Colley III's A68 6800 cross-assembler. The A68 assembler runs in DOSBOX under Microsoft Windows. Output Format...

20230216b -- "Files"
Log from ROM Disassembly - AlphaSmart Pro
The gist of this unit is that you type text into a discrete 'file' and then you can edit and later transfer to a separate computer via the keyboard emulation. While whizzing through the code doing other things, various strings caught my eye, such...

Building an EC sensor.
Log from Autodro
The end goal for the Autodro is a complete monitoring system for under $10. This means that cheaper, simpler, less accurate sensors are needed. I've started with a simple EC sensor, and am hoping to design something around $1.So far, I've created a sensor...

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...
