  • Details     from SolidCore CoreXY 3D Printer
  • SolidCore CoreXY CAD Design In Fusion 360 All Metal Parts Our long term goal is to is to build a modular platform, not just a printer. Think of it as an ecosystem of parts that can be arranged in different configurations and adapted for unique applications....

  • 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...

  • 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...

  • All Your ISA Belong to Me!
  • Log     from DDL4-CPU
  • Before I began the layout of the DDL4-CPU, I came up with an initial Instruction Set Architecture (ISA) for the design. It went through several revisions as I was designing the boards and refined the components. Here at the last minute as I am...

  • I2C on OPT8241
  • Log     from 3D-ToF scanner
  • I have connected the opt8241 sensor over I2C. I have disabled sensor clock by setting MCLCK to 0. Power consumption of adapter board is ~1.8 mA. Then I have sent the i2c commands. Command output : # i2cdetect 2 WARNING! This program can confuse your...
