MNIST clock: A clock for ML engineers

If you're a machine learning engineer you have probably used the MNIST database by Yann LeCun numerous times especially in the early days of neural networks. If those days bring memories to you, this clock is for you. It uses four small e-Ink displays and stores about half of the entire MNIST dataset in 2-bit resolution on a ESP32 and displays the time, sync'ed to NTP so you never have to set it of course. For plans and code head to this Github repo.

The idea for this clock came from a sketch by Evan Pu who I know from MIT.
