A View Into the Soul of the Sol-20
Log from Sol-20 Reproduction
From the beginning of my work on the Sol-20 reproduction I wondered what kind of display I would use with it. Of course a small CRT based TV or monitor would be ideal. To that end I put out feelers with my maker mates and even had someone at a local...

Initializing ROM during build-time from files
Log from From bit-slice to Basic (and symbolic tracing)
(for related subject, run-time initialization of ROMs/RAMs, see here) FPGA-based designs often have various read-only stores. Their content can be defined in different ways: Inline in the source code (appropriate for smaller ROMs)Using vendor-specific...

Analogue Wind Vane With Auto Set Up
Log from Arduino GPRS IOT Weather Station
As the amazing online GPRS Weather Station project continues, we have yet another upgrade to the vast array of sensors with a professional analogue wind vane, kindly donated by Vector Instruments. This device will eventually be hooked into the new, upgraded,...

Implementation in VHDL - RAM and lookup tables
Log from Iskra EMZ1001A - a virtual resurrection
RAMAll EMZ1001A RAM is implemented on chip, as 64 nibbles, arranged as 4 * 16 matrix, addressed by 2 bit BU (mr_bu) and 4-bit BL (mr_bl) registers. There is really no provision for external RAM, although possibly it could be implemented by INP and...

[E1][T][M] Tetent with 1440px screen?
Log from Tetent [gd0090]
1440x1440px resolution at 125% scalingWhat the screen would look like on Tetent (but sharper). This already makes me think back to my Windows Vista on PSP days, but I'm mainly imagining the future present of quietly chilling in bed while trimming down...

Salinity Measurement
Log from Vinduino, a wine grower's water saving project
SummarySalinity, or excess salt in the soil profile, is often called the "silent killer", because of the devastating effect salinity can have on irrigated agriculture. With increasing agricultural irrigation efficiency, there is a risk of salt build-up...

simple thing that can speed up any ili9341 display in my case additional 20%
Log from spi write up to 64 colors at a time on Arduino!
Since i have been getting the ili9341 display ready for fast 32x32 (and 64x64, 128x128) subsampling of amg8833 sensor the ili9341 display has 4 times as many pixels as the st7735 display i have working at fast speeds. to increase performance i am doing...

3D Print Raaco Handybox Inserts (A9-1)
Log from Parts Boxes
At first, I bough extra compartment inserts. But realized shortly after getting my first 3D printer, that designing and printing my own was going to be cheaper and quicker. The dimensions of the smallest box are specified as 39mm wide x 55mm deep...

Initial work
Log from I2C interfacing UMFT4222EV module
2020-11-16 Downloaded libft4222-linux-1.4.4.9.tgz and unzipped it. Ran the command: sudo ./install4222.sh and got no complaints. In the examples/get-version.c file, there are instructions for Linux: cc get-version.c -lft4222 -Wl,-rpath,/usr/local/lib...

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...

ROM checksum code
Log from Re-UD-80 - a larger display for Epson PX-4 / PX-8
The 5.21E ROM works file with the current board, but the 7.11A ROM uses a different pin for the vertical sync signal. This can be fixed, but then the 5.21E ROM results in no display. Rather than fixing the hardware (with a jumper to be changed when the...

What
Log from Reverse-Engineering a low-cost USB CO₂ monitor
In past projects I've had raging successes by just looking at the raw data, XORing stuff together, and maybe squinting my eyes a little. Spoiler: Not so this time. I'll walk you through the steps anyway.---------- more ----------What we know: Data comes...

Microcode Design in Progress for A1 with a Newly Modified Bus Architecture
Log from AOZORA
The targeted decoding ROM is going to have 8-bit output. Under such restriction, the number of microcodes has to be not grater than 2^8 = 256 = 16 x 16. Operation / Data FlowCoding SpaceCommentB < B1 < Bus-C < RegB > B0 > Bus-B > Reg2 x 16Totally 16...

1K Challange Laser
Log from 1K Challange Laser
At this point, we decided to abandon the concept of mirroring. If we had had a much more complex design with many more points and more than 1kb, mirroring would have saved us space. Due to having so little space however, the algorithms power wasn't able...
