PicoSavvy Posted May 16, 2020 Share Posted May 16, 2020 So I and my engineering buddies sometimes send each other short videos of stupid stuff we do in our free time. Today I sent this project to them from stuff I had laying around the house. It is almost all made from lego expect for the hot glue and magnet. All I need to do is patent it 🤣and make millions then corner the market with the first-hand crank aquarium pump for blackout emergency or if you have small critter friend like a hamster you can have the world first hamster power magnetic coupling based flow pump. But anyways my friends got a laugh out of it hope some of you guys do too. It is almost saltwater rated all you need to do is change the hot glue for epoxy 😂  2 Quote Link to comment
mcarroll Posted June 11, 2020 Share Posted June 11, 2020 Hot glue is fine in saltwater.  Lego makes motor drive units....what gives???  Seems to run the same flow strength as a real Vortech!   Quote Link to comment
