CP/M-86 is out!
Log from V20-MBC: a V20 (8088 + 8080) CPU homebrew computer
CP/M-86 is out! Remember to update both the IOS firmware and the SD image (see Files section):

TI-86 LCD interfacing
Log from Vintage Z80 palmtop compy hackery (TI-86)
On the LCD board is a big TQFP that some might think to be the "LCD Controller"... That's not quite the case. That chip is a T6A40, NOT T6K04: the latter is apparently used in TI-83+ and others, and is an entirely different concept. Consider it,...

TI-86 OBDing Revisited
Log from Vintage Z80 palmtop compy hackery (TI-86)
I started peeking back into my TI-86 OBD-reader yesterday... Van's acting-up again, a little. I was surprisingly far with it, already able to send-then-receive via the bitbanged UART, but it's a weird path I went down... Thing is, my van has two of the...

TI-86 Logic Analyzer
Log from Vintage Z80 palmtop compy hackery (TI-86)
Ok, so it's gnarly-dusty and that's not real sample-data, but here goes: That's two lines of sample-data, from the link-port, wrapping, to show as much as reasonably-viewable (1024x2 Samples visible). Presently, I think each sample (pixel) is around...

Iteration A4
Log from 6-Axis Micro Manipulator
So after a few iterations of re-design to work with NEMA-8 sized stepper motors which whilst not the smallest available are the smallest in the sub $20 bracket. In this case $12ea. With the increased size comes the headach of deciding on an arrangment...

TI-86 addon FLASH written!
Log from Vintage Z80 palmtop compy hackery (TI-86)
Woot! This is my first time coding-up a FLASH writing algorithm... Kinda been wanting to do-so for a while... sorta thing I'd add to #commonCode (not exclusively for AVRs).(Huh, how's this stuff fit in with that? We're writing ASM, here, that's C for...

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...

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...

95% complete, a problem remains
Log from Digital Photo Frame from obsolete laptop
Computer is framed, software is all configured, but one annoyance remains: a 13.5khz whine that I have isolated to the CFL backlight driver (I thought). I need to quiet that down or it'll drive me mad! I tried foam insulation around the frame - didn't...

Understanding how the computer works
Log from Apollo Guidance Computer
Fortunately most of the NASA documents are available. They can be found on-line at https://www.ibiblio.org/apollo/Documents/ The following documents are what I leaned heavily on in gaining an understanding of how this computer...

TI-83+, 86 linking rambling
Log from Vintage Z80 palmtop compy hackery (TI-86)
did a quick test comparing the linking of the 83+ and 86 via blacklink cable through a usb converter... The results are nearly identical. I did quite a bit of hackery to the tilp2 linking library a while back. One change was to verify the writes before...

All boards received
Log from NEDONAND homebrew computer
The rest of the boards just came:I think I will connect them together through wire-wrapped "motherboard" (lets call it "NEDONAND-10" ; )All of these NEDONAND components could be tested one by one using PIC microcontroller (connected to PC through RS-232)...

How ESP-NOW really works ?
Log from Linux-ESPNOW
To implement the ESP-NOW Protocol, we first need to understand how it works in details. The datasheet doesn't say much on the really low level, especially on the acknowledgment behavior. To understand what ESP-NOW does, I use Wireshark with my PC Wifi...

E2 Emulator
Log from Kestrel Computer Project
Sometimes, I get burned out by the hardware aspect of the project. When this happens, I often wonder to myself, "Man, if only I had the Kestrel *finished*, then I can work on the software." I reached that point not too long ago.So, I worked...

9/20/23 Update
Log from 1802 MemberChip Card
I added a link to Josh Bensadon's short Youtube video demo of the MemberChip Card. (Thanks, Josh! I've never made a video in my life, and didn't know how I was going to add one to meet the contest rules.) I now have a program to read files from the upper...
