| | | | | After getting the Arduino and SP0256A-AL2 working I wondered if I could repeat the trick from the Arduino and AY-3-8910 and have the Arduino generate the required clock signal for the SP0256A-AL2. This post starts to look at that question. https://makertube.net/w/paGX4eiCAHgLU9mK2x3uyq Warning! I strongly recommend using old or second hand equipment for your experiments. I... | |

| | | [AI summary] This project involves replacing the electronics of a 747 fuel quantity indicator with a custom system using a Raspberry Pi Pico microcontroller. The system uses a PID controller to manage the pointer and counter movement, with a focus on addressing issues like noise and derivative term sensitivity. The project successfully controls the indicator, though some challenges remain, such as a noisy potentiometer around 22,500 pounds. | ||
