Simple Z80 test design - single board with all the basics and a few luxuries.
Please do post comments down below if you find any of this interesting, I'd love to share thoughts on how this could be improved in future! I've noticed a few people have cloned it and a few have starred so I'd love to hear from you all.
The board has many more options than it really needs so that I can experiment. All...
An 7 instruction, 4-bit Processor with a serial Arithmetic Logic unit with 4 operations (OR,ADD,SUBTRACT,MULT) that I designed in my free time. feel free to use the design for whatever you want as long as you credit the original :)
0000(With data input): ADD
*Input bus (D0-3) Swiches between data...
V2 of my ZTO-80 SBC project, with the end goal of having color graphics(?) along with a BASIC interpreter based off of NASCOM BASIC. A future revision may include support for CP/M.
Feel free to clone this project. Just be sure to acknowledge me as printed below:

This is a CP/M 2.2 computer (pre-IBM). It is working.
It is unique in that it uses the the SIM/RIM instructions and SID/SOD/RST6.5 pins for Serial IO. It uses a 5V USB serial adapter for power and communication to your computer (using a serial terminal program).
There two problems with this approach in that the processing delays between Serial IO means that character can be missed if data is sen...
ESP32-WROOM-32 is a powerful, generic Wi-Fi+BT+BLE MCU module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding.
At the core of this module is the ESP32-D0WDQ6 chip*. The chip embedded is designed to be scalable and adaptive. There are two CPU cores that can be individu...
