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...

Day 8a: convoluted ALU design
Log from Detritus, the 8-bit ... computer?
Having picked a crazy overkill instruction set, it's easy to see how those functions map out in an ALU. 2 registers; an adder; and four logic functions. I spent some time over the weekend thinking about how this maps out to a final design, and in particular...

The actual informations
Log from Extension card for TDS3000 scopes
Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....

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...

Adapter for Stabilo point 88
Log from Plotter art with Mutoh iP-220
I learned a lot trying to use adapters from Aliexpress and eventually got them working after some modifications, but up to now I couldn't find any good quality refill pens which I could use with them. So I will go back to that later on.For most of my...

Soldering perfboard
Log from Earth Lander 84
I took a perfboard and soldered up power and the data/address busses of the MCU, SRAM, NVRAM and the address bus latch.I did't really care about the exact order of the bits when wiring them up, I just went for the easiest layout. I'm not really sure...

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)...

Paper Model now Steps. Stepping algorithm optimized. 11 bytes saved.
Log from Mystery 6502 program for the Kim Uno #1kBChallenge
I was looking for a way to make the Excel Paper Model for the Z30 calculate the stepping points so it would be a complete model of the machine. The example shown below is for a rotor with a Ring Setting of 4, the 1 mark on the ring is set to the 4 position...

[T] A3 Contact Image Sensor
Log from Tetent UMPC [gd0149]
It's almost certain at this point that Leti will be over 300mm long, so only having a scanner that can do 210mm seems like a bit of a missed opportunity. Unlike A4, a handheld A3 document scanner basically doesn't exist. There are A3 all-in-one printers...

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...

New Boat, New Autopilot - using an old laptop mainboard!
Log from OpenCPN Chart Plotter /w Autopilot and Waypoints
For quite some time I have been thinking about the possibility to using a laptop to run all the heavy OpenPlotter and OpenCPN stuff instead of using a Raspberry Pi. The performance of the RPi is... well it's usable but it's not a pleasant user experience....

[T] Inbuilt A4 Document Scanner
Log from Tetent UMPC [gd0149]
Since I'm unbound by the generic requirements of "the masses" and have complete idea freedom until "the rubber hits the road", as they say, I was wondering about any additional features I could install into Leti. The requirement was that:it had to actually...

nedoPC-85-MK v1.0
Log from nedoPC-85
This one could be a standalone 8085-based computer with Cherry-MX keyboard on board, 12 5x7 LED matrices and 6 7-segment indicators with some additional indication and stereo-audio output (2 channels with 4 bit per channel): Intended to resemble look...

66% vs. 85%
Log from bag hacking
Lessons learned from making the pattern at 66%:foam does not belong on such a small bag -- it is too structuredthis is like the right size for a tween purse or little girl purseSo now I've made the pattern at 85% of normal size as well. I never came...
