Raspberry Pi 4B with Prusa MK3s / Einsy RAMBo headers

Raspberry Pi 4B with Prusa MK3s / Einsy RAMBo headers

The guide below describes how to connect a Raspberry Pi 4B to the Prusa i3 MK3s main board (Einsy RAMBo) board with its builtin RPi headers and an additional step-down / buck converter. The buck converter is necessary, since the Einsy headers do not provide enough amps to power anything bigger than a Raspberry Pi Zero W.

Parts needed

Clear Rocket.Chat uploads periodically (before #11236 [message pruning] existed)
#!/usr/bin/env bash
# Script to remove old uploads in Rocket.Chat instances for people using the filesystem storage method.
# This script makes sure to NOT remove users avatars. Because they are stored in the same directory we
# have to query the Mongo to check if a file is a regular file upload or a avatar.
#
# Env vars:
# - DELETE_OLDER_THAN_DAYS (defaults to 5)
#
# Written by: Jonas "frdmn" Friedmann <j@frd.mn>
# Requirements: mongo (cli), docker-compose, jq, tofrodos package
