Live Apollo 11 Transcript On EInk Display

There are few moments in history that have ever been recorded in more detail or analyzed as thoroughly as the Apollo 11 mission to the Moon. Getting three men to our nearest celestial neighbor and back in one piece took a lot of careful planning, and recording every moment of their journey was critical to making sure things were going smoothly. As we celebrate the 50th anniversary of man’s first steps off our world, these records give us a way to virtually tag along with Armstrong, Aldrin, and Collins.

As part of the 50th anniversary festivities at the Parkes Radio Telescope in Australia, [Andrew] created a badge that would let him wear a little piece of Apollo 11. Using an ESP32 and an eInk screen, it replays the mission transcript between the crew and ground control in real-time. It’s a unique way to experience the mission made possible by that meticulous data collection that’s a hallmark of the National Aeronautics and Space Administration.

[Andrew] was inspired by the “Apollo 11 In Real Time” website, but rather than pulling the content from the Internet, he’s loaded the mission transcripts onto the ESP32’s SPIFFS filesystem as a CSV file. Not that the badge is completely offline, it does need to connect to the Internet (via a hotspot on his phone) so it can keep its internal clock synchronized with NTP. Keeping everything local does reduce power consumption compared to streaming it from the Internet, but he admits that otherwise he didn’t give much thought to energy efficiency and there’s definitely some room for improvement.

The LILYGO TTGO board he’s using combines the ESP32 with a 2.13 inch eInk display, in a formfactor not unlike the Badgy we’ve covered previously. He was able to find a STL for a 3D printed case on Thingiverse which he modified to fit a battery. Unfortunately the original model was released under a license that prevents him from distributing his modified version, but it doesn’t sound too difficult to replicate if you’re interested in building your own running ticker of humanity’s greatest adventure.
