The Spark Gap - Episode 53

The Spark Gap · 31 Jan 2018 · 54m

What this episode covers

Corey discusses his ongoing ping pong scoreboard project, which uses discrete logic chips like the CD4026 and struggles with CD4518 counters due to clock rise time violations at 12V. He details his debugging process involving breadboards, hex buffers, and the decision to design a PCB using Fritzing. Meanwhile, Karl introduces the STM32F723ZE microcontroller, highlighting its built-in USB High-Speed PHY, but warns of software library incompatibilities, and outlines his own project: a custom CNC Raspberry Pi hat integrating an Arduino and RS485 communication for a variable frequency drive.
