Desktop portable Stargate 🌌🛸💡

Always liked the episode of SG-1 when Orlin made a mini Stargate using various parts ordered online and from Major Samantha Carter's toaster. This one at least fits in our apartment, all part of the round LCD work we are doing with the ESP32-S3.

Mini Stargate

The Mini Stargate was a miniature Stargate constructed by Orlin in 2001. Orlin's Stargate is a much smaller, more primitive version of a Sta

MJPEGs are a great way to play small animations on TFTs 🎞️ 🖥️ 🔄

With our ESP32-S3 TFT experimenter board, we're now able to use the Arduino_GFX https://github.com/moononournation/Arduino_GFX library by moononournation which has native RGB TFT support and excellent example code. This example is playing MJPEG files, a simple animation format https://en.wikipedia.org/wiki/Motion_JPEG with just JPEGs glued together. We wired up a MicroSD card over SPI for quick file storage and retrieval, or 1-bit MMC works, too. files are converted with ffmpeg: 'ffmpeg -i "wash.mp4" -vf "fps=10,vflip,hflip,scale=-1:480:flags=lanczos,crop=480:480" -pix_fmt yuvj420p -q:v 9 wash.mjpeg', natch! And then they play, about 9fps is the rate we're getting for 480x480 pixels.

PCB of the Day! ESP32-S3 can drive TTL RGB Displays 🔧🖥️🎨

Coming soon - this is a quick sketch we did of an RGB TTL driver PCB to help us try out all our funky-shaped displays. We reused most of the Matrix Portal S3 PCB, but instead of the RGB matrix connector, we popped on a 40-pin FPC. 16 GPIO go to the RGB pins, then there are 4 control pins for HSYNC, VSYNC, DE, and PIXCLK. Three more pins for touch screen I2C and IRQ. Then a NeoPixel, two buttons, and 3 SPI pins for configuring the screen controller, and we're almost out of pins! An I2C GPIO expander could save us a couple pins at the expense of more complex drivers, but for now, we will make it easy to get the displays running, and we can play silly pin games later.
