This RC sub has magnetic couplings to transmit torque through the walls. No need to drill holes = no leaks. At the end I test it in a swimming pool. Enjoy!
Differences to the first sub
-rectangular hull (need flat walls for magnetic couplings)
-snap-and-lock lid (more reliable, less leakage)
-bigger motors, more motors, more propellers
-depth control using propellers (IMO more accurate compared to a syringe ballast tank)
-lead pellets for ballast (easier to adjust, both shape and weight, compared to steel plates)
-captain (thanks everyone for pointing out this obvious missing part :))
The submarine specs:
Displacement: 2.7 kg (6.0 lb)
Test depth: 1.5 m (4.9 ft)
Hull: glass food container (IKEA 365+ 1.8l), plastic lid
Motors: 3x Lego XL-motor (8882-1)
Magnetic couplings: K&J Magnetics R844-N52 neodymium magnet, TapeCase 423-5 UHMW Tape
Propellers: Lego propeller blade (2952), Lego liftarms
Radio control: 27 MHz controller dissembled from a toy submarine (Zantec Mini RC U Boot), L298 H-bridge to drive motors
Power supply: 9V Lego battery box for the motors, 3.7V Li-Po for the RC
Onboard camera: Faironly Firefly Q6
Pressure sensor: Jolly Logic Altimeter One

A MAN IS DRIVING A SUBMARINE IN LEGO CITY
You're fcking cooler than Elon dude..seriously
This is so dope
Me:can I buy one of these thingys?
Store:we’re out of stock
Me:🥺
Store: on the top shelf
This is awesome. I loved how you showed the…what, physics/engineering when it came to the problems you encountered and the fixes you came up with. Good stuff.
Asmr lego building
Me: his submarines gonna be flooded with water.
Him: today we are gonna be using something called an ikea lunchbox and magnets
That’s the best pirate I’ve ever seen
This is PURE GENIUS!
2 questions…and I sincerely apologize if these are obvious. 1) Why was the low-friction tape necessary? 2) Can you please provide more context on the change made to the surfacing/diving props? What changes did you make and how did those changes correct the spinning problem?
Man this is so gooooood content
I wish I could do this but my parents say legos are a waste of money 😞
Yellow submarine
put a mini cam inside 😁👍
That is an awesome Lego submarine!!!!
Can you please try to make a clock from legos?
Mumbo jumbo but with legos
Hey brick experiment channel, Try attempting to make a working air raid siren out of Legos. Using a gear ratio. But a high speed one.
Genius.
Hi I have a new channel please subscribe
What are you doing playing lego?!?! Go build a droid or a satelite or some thing! Dude, you are damn smart!
Amazing
That's cool dude you should try out for Lego Wars
Me: Mom can we get a submarine
Mom: we have submarine at home
Submarine at home:
YOU'VE MADE A SUBMARINE WITH LEGO! WHAAAAAAAAAA
military/navy: hmm.. we need something that can search under water and it needs to be a little bit cheap
Him: hold my captain-
я один здесь руский а!
