This amazing device unloads all your goods you send up from the mine into a chest, and then sends the minecart back down when it's done! Amazingly small and simple!
Nicely done minecart unloader with auto cart return.
Reasonably cheap version good for instances where item volume is not extreme.
Well done on explaining the RS circuity in a way likely to be comphrehensible to new-RSers :>:
RE the video presentation:
Concision; most of the 1st three minutes could have been cut IMO, perhaps they appeal to a different demographic?
Technical: repositioning or otherwise adjusting your mic so that it doesn't pick up your keystrokes would remove a distraction.
WARNING: I have an extemely "grindy" playstyle; YMMV — if this doesn't seem fun to you, mine what you can from it & bin the rest.
