The M5PaperS3 is a low-power e-ink development kit built around the ESP32-S3 microcontroller. This lightweight device features a 3.7V 1800mAh LiPo battery and a MicroSD card slot, designed for use in applications such as IoT monitoring, smart home systems, electronic labeling, and data logging.

As I briefly mentioned yesterday, someone mentioned in this blog's comments a successful M.2 socket installation on the empty header on the Pi 500 (something I attempted, rather poorly!). With a few added components, and 3.3V supplied to a pad on the bottom via a bench power supply, the M.2 slot works just fine, allowing the use of NVMe SSDs or other PCIe devices.

My TVTR receive lineup uses an LNB frontend into a downconverter. The output from the LNB (618MHz) is split between the downconverter and a port suitable for an SDR unit. So I decided to try a Raspberry Pi (RPi) with a touch display and after some research ordered a RPi 4b with 4GB of memory and a Waveshare 5″ DSI Touch Display. The RPi was configured to run the latest Debian Bookworm OS with desktop UI and GQRX for the SDR software. I really was not sure how good the display would be, but based on my results so far it’s really great in terms of size, touch usability and display quality. How good it will be outdoors in sunlight remains to be seen.

I finally got Jops to generate a good DiagROM serial output, but the video output wasn’t working. This time I dig further into why that is happening.

When I first heard about this paper from the second author, Chris Corley, he said something to the effect of “the easiest way to detect if a programmer is in flow is to see if they’re typing into their programmer’s editor.” This is the approach I wanted to implement.
