Running short fragment of program - but needs a lot of fixing!
Log from Let's experiment: NEC V20 + FPGA
I have squeezed some simple instructions into a 16-byte ROM that writes 0x04 into the I/O address 0x00, and repeats (http://www.homebrew8088.com/):A: MOV AL, 04 OUT 00, AL JMP AThis is then converted into machine code (https://defuse.ca/online-x86-assembler.htm),...

2020-08-04 Progress update - SFC/SNES support
Log from BlueRetro
Finished basic SNES 2P support and some experimental 5P Super Multitap support. Multitap can be configured by setting multitap config to Slot 2 in the Web Bluetooth interface. I also fixed a config corruption bug that impacted mostly PS3 & PS4 controllers....

Self Optimising Automated Arduino Nutrient Doser
Log from Hacking the way to growing food
This Blog is about making a nutrient dosing system for hydroponics that is plug and play, I didnt quite get it to the full stage of plug and play with this version. But it is almost there. Because the change of nutrient strength of our systems can be...

Three Dollar EC - PPM Meter [Arduino]
Log from Hacking the way to growing food
This Blog will Cover How to build a cheap EC meter for your aquaponics/Hydroponics or water quality related projects. We are not going to get into what the ideal value of PPM or EC is, Just cover how to measure and quantify a fluid.We will be using this...

Z80 (CP/M) Writing to SD Card
Log from 3-Chip Z80 Design
Digging into SD card writes means shifting gears from the Boot BIOS source code since the Boot BIOS code only does reads. The CP/M BIOS code (CBIOS128.LST) which does the reads/writes after booting. Here's the BIOS code for writes to the SD Card: 0754...

Topology (1)
Log from Programmable Precision Resistor
In this post I want to share how I selected a suitable topology for the resistor network that will be the core of the programmable decade resistor. Although I did some online “research”, the following criteria determined my choices: Switch...

Project Log 67: DIY Linear Actuator.³
Log from DIY Mech/Exoskeleton suit.
Sunday, 13/08/2023, 10:55. I can't believe I'm saying this, but I think I will go back to the reversibly actuated artificial muscles. Yes, I know, I know, I just wasted so much time taking each single approach for their efficiency and now I'm throwing...

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...

B1+B2 completed. Also, facing my first real problems.
Log from 74HCT6526
Finally, B1 and B2 are completed and they.... kinda work... Although I'm going to have to check quite a few things.Remember how B0 performed flawlessly, both when connected via the expansion port, and when replacing CIA#2? Well, that's no longer true....

Capturing data from the bus
Log from Harley Davidson J1850 Visual Display Interface
The first step in this project was to scope the signal on the data bus, which uses J1850 VPW, to verify I had the right source for the data, verify the voltage, and verify the signal itself. I had a few automotive 3-pin connectors lying around, so I...

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...
