Lego PF Medium Motor with gears and pulleys lifts a hefty 102.2 kg. Gear ratio 15:1 and tackle velocity ratio 8:1. Only lego parts were used, except for the string. Enjoy! 🙂 Development videos: Part 1 pulleys: https://www.youtube.com/watch?v=KUjVby8H-bQ Part 2 gears: https://www.youtube.com/watch?v=umN2iHsw3UY Part 3 gears and pulleys: https://www.youtube.com/watch?v=slv5fvS6e9Q List of parts: 1.5 meters of string Stabilit Vielzweckschnur auf Polyamid 1.3 mm, max 25 kg (bought from Bauhaus) 1x Power Functions M-Motor (8883) 1x Power Functions Battery Box (8881) 1x Power Functions Control Switch (8869) 2x Plate 2 x 16 (4282) 2x Plate 2 x 4 (3020) 12x Technic, Brick 1 x 16 with Holes (3703) 2x Technic, Brick 1 x 6 with Holes (3894) 6x Technic, Brick 1 x 4 with Holes (3701) 1x Technic, Liftarm 1 x 2 Thick (43857) 1x Technic, Liftarm 1 x 2 Thin (41677) 2x Technic, Pin 3L with Friction Ridges Lengthwise (6558) 2x Technic, Pin with Friction Ridges Lengthwise WITH Center Slots (2780) 1x Technic, Axle 16 (50451) 2x Technic, Axle 12 (3708) 4x Technic, Axle 6 (3706) 4x Technic, Gear 40 Tooth (3649) 2x Technic, Gear 24 Tooth (3648) 6x Technic, Gear 8 Tooth (3647) 3x Technic Wedge Belt Wheel (Pulley) (4185) 9x Technic Bush (3713) 5x Technic Bush 1/2 Smooth (4265c) The pulley block parts: 4x Technic, Brick 1 x 8 with Holes (3702) 3x Technic Wedge Belt Wheel (Pulley) (4185) 3x Technic, Axle 8 (3707) 1x Technic, Axle 10 (3737) 8x Technic Bush 1/2 Smooth (4265c) 18x Technic Bush 1/2 Toothed Type I (4265a) Note to builders: Protect your eyes and fingers! We are dealing with some serious forces here.
Épisode 5 - What Happens If You TWIST a Lego Axle HARD?
30 juin 2018
Let's sacrifice one Lego axle to see how it deforms or breaks when high torque is applied. The results (using PF M-motor): 1:1 (40 mNm) - ok 3:1 (110 mNm) - ok 5:1 (180 mNm) - slight permanent deformation 9:1 (300 mNm) - serious permanent deformation 15:1 (500 mNm) - even more serious permanent deformation - (? mNm) - breaks in half
Épisode 6 - Spinning a Lego Wheel FAST
14 juillet 2018
How fast can you rotate a Lego wheel & tire using a Lego motor and gearing? Let's find out.
Épisode 7 - Testing Lego gear and pulley systems - part 2
28 juillet 2018
Last time we passed 100 kg, barely. This time the target is 200 kg. Hopefully I won't break as many pieces as last time. The purpose is to generate the maximum possible lift force with a single Lego PF Medium Motor. Special thanks to Imanol BB from Eurobricks with his pulley block design done with Lego Digital Designer. https://www.eurobricks.com/forum/index.php?/forums/topic/157532-lifting-heavy-loads/
Épisode 8 - 30 Volts to a Lego Motor
11 août 2018
Let's increase voltage on a Lego PF Medium Motor and see how it affects torque (by measuring lift force). Where's the limit? Does the motor have a protection circuit? Will the motor smoke and catch fire?
Épisode 9 - Lego Motor Lifts a Rock (88kg/195lb)
25 août 2018
Some of you wanted to see Lego motor lifting an actual weight instead of a meter. Here you have it. 88 kg of granite is lifted to a height of 20 cm. It took 21 minutes. 🙂 Compared to the 220 kg machine, some changes were needed to increase the lifting distance: -String collection around the axles was widened from 1 to 2 Lego units. -Bushes used for strengthening the axles were replaced with Technic Reel 3 x 2 (32012). -Gear ratio was increased from 75:1 to 135:1 to compensate the increase in diameter (and therefore loss of tension) when a lot of string is wound around the reels. This also means that the reels or axles may break if put to maximum load when the reels are empty.
Épisode 10 - Spinning a Lego Wheel FASTER
8 septembre 2018
How fast can you rotate a Lego wheel using gears and a Lego motor or two? Last time we got to 2850 RPM (2950 with a drill). Now, let's remove the tire that caused a lot of vibrations and try again. Also test two types of lubrication: canola vegetable oil and silicone spray.
Épisode 11 - Testing Lego Worm Gear HIGH TORQUE Performance
22 septembre 2018
Lego worm gear is a fast track to high gear ratios. But is it efficient? Let's find out.
Épisode 12 - Spinning Contest with 10 Lego Wheels
6 octobre 2018
Which is the fastest Lego wheel? 10 participants are spun on a test rig and the winner is the one with the highest velocity. The score (linear velocity) depends on wheel size (circumference) and how fast it rotates (RPM measured using a laser tachometer). Enjoy! Participants: 1.

Épisode 14 - Building and Testing a Lego Press
3 novembre 2018
A short version of the previous long development video + new tests at the end. The target is to generate the maximum possible pressing force with Lego. The progress is measured using a disassembled person scale (max 180 kg). Enjoy! The long unedited version: https://www.youtube.com/watch?v=vl6gLxoT1vs p.s. Some of the gear ratios in the video are incorrect. Instead of 36:1 there should be 25:1. And 54:1 should be 45:1. Somehow I forgot that a middle sized bevel gear has 20 teeth, not 24.

Differences to the first sub https://www.youtube.com/watch?v=tGEZApd9MMk -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 Link to the magnets used in the couplings: https://www.kjmagnetics.com/proddetail.asp?prod=R844-N52 Music: Tommy Baynen - Laminar Flow [Colorize] https://colorize.ffm.to/encolor222 https://www.youtube.com/watch?v=UPdR8lh4a1o https://soundcloud.com/tommybaynen
Épisode 31 - Building a Lego Tank that Shoots Lego Soccer Balls
15 août 2020
My attempt at a radio-controlled Lego tank that launches Lego soccer balls (= Lego GBC balls) using a rubber band powered gun. Nothing special in the hull, tracks and suspension. Many other Lego builders like Sariel, Kelkschiz and Matze Glatze have built better Lego tanks. But the gun is pretty powerful. I've never seen anyone make one that shoots soccer balls or uses a long wind up string to arm the rubber band. Theraband Gold was my choice for rubber band (very popular in real slingshots). The result is a bit dangerous. Not for kids! Use eye protection if you ever try to make it. The video is edited in retro 70s style with funky music. Enjoy!

Épisode 42 - 33 Lego Wheels/Tracks on Wood (worst to best)
24 avril 2021
33 Lego wheels, tires or tracks tested on a wooded board to find the best traction. Presented in order from worst to best. Enjoy! Test method: adjust the slope angle until the driving car doesn't slide down or climb up but stays in place measure the angle of inclination calculate the coefficient of friction = tan(angle) Potential sources of error: traction varies along the wooden board (maybe +/- 1 degree of error in spots) wheel rotation speed varies (faster rotation adds maybe even 2 degrees to the result with some tires, tried to minimize it by using L-motor with large tires) vibration (happened noticeable only with 15038c03, those errors were omitted) weight varies (shouldn't matter in theory) uneven weight distribution on the 4 wheels angle measurement inaccuracies == the results are not very accurate, but I'm confident they are roughly correct All wheels were wiped clean before testing. The material of the wood board is pine, untreated https://www.biltema.fi/rakentaminen/sailytyshyllyt-ja-hyllytarvikkeet/yksittaiset-hyllyt-ja-hyllykot/hyllytasot-liimalevysta-2000018835 Test results: angle, cof, release year, diameter, part id, link to bricklink.com 13 0.23 1979 -- 3873 https://www.bricklink.com/v2/catalog/catalogitem.page?P=3873 14 0.25 2007 -- 57518 https://www.bricklink.com/v2/catalog/catalogitem.page?P=57518 18 0.32 1977 41 3649 https://www.bricklink.com/v2/catalog/catalogitem.page?P=3649 22 0.40 1977 36 3736 https://www.bricklink.com/v2/catalog/catalogitem.page?P=3736 30 0.58 2006 -- x1681 https://www.bricklink.com/v2/catalog/catalogitem.page?P=x1681 30 0.58 1981 64 4266c02 https://www.bricklink.com/v2/catalog/catalogitem.page?P=4266c02 32 0.62 1975 42 3482c03 https://www.bricklink.com/v2/catalog/catalogitem.page?P=3482c03 33 0.65 1974 24 3482c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=3482c01 33 0.65 1986 43 2695c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=2695c01 34 0.67 2013 -- 57518+14149 https://www.bricklink.com/v2/catalog/catalogitem.page?P=14149 36 0.73 1983 30 4185c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=4185c01 38 0.78 2016 -- 57518+24375 https://www.bricklink.com/v2/catalog/catalogitem.page?P=24375 40 0.84 2010 14 4265cc01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=4265cc01 45 1.00 2014 95 15038c03 https://www.bricklink.com/v2/catalog/catalogitem.page?P=15038c03 46 1.04 2016 105 15038c05 https://www.bricklink.com/v2/catalog/catalogitem.page?P=15038c05 47 1.07 2006 94 44772c02 https://www.bricklink.com/v2/catalog/catalogitem.page?P=44772c02 48 1.11 2001 103 22969c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=22969c01 48 1.11 2010 94 88517c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=88517c01 49 1.15 2007 30 55982c03 https://www.bricklink.com/v2/catalog/catalogitem.page?P=55982c03 49 1.15 2009 43 56904c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=56904c01 49 1.15 2011 67 56908c02 https://www.bricklink.com/v2/catalog/catalogitem.page?P=56908c02 49 1.15 1994 42 6580c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=6580c01 50 1.19 2006 43 56145c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=56145c01 50 1.19 2003 43 44292c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=44292c01 51 1.23 2008 43 56145c04 https://www.bricklink.com/v2/catalog/catalogitem.page?P=56145c04 51 1.23 2006 55 56145c02 https://www.bricklink.com/v2/catalog/catalogitem.page?P=56145c02 51 1.23 1991 83 2903c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=2903c01 52 1.28 2003 70 44772c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=44772c01 53 1.33 2011 80 56908c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=56908c01 53 1.33 1990 49 4266c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=4266c01 54 1.38 2000 56 6595c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=6595c01 54 1.38 1998 68 32077c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=32077c01 54 1.38 1997 63 32020c01 https://www.bricklink.com/v2/catalog/catalogitem.page?P=32020c01 Music: Heaven and Hell - Jeremy Blake https://youtu.be/T9IXodtjRgs Blue sky video footage: NoCopyrightVideoHD https://youtu.be/JmG7iqB-AuA

Épisode 44 - Build & Test Lego Engines: V8, U12, H16, X24, multirow-radial-42, S100
12 juin 2021
More engines. Bigger ones. Enjoy! 00:00 V8: 8-Cylinder V-Engine 01:04 U12: Twin-Straight-6 U-Engine 02:38 H16: 16-Cylinder H-Engine 04:38 X24: 24-Cylinder X-Engine 06:11 42-Cyl 7-Row Radial-6 Engine 09:49 S100: Straight-100 Engine 11:34 side-by-side and sound comparison Note: In real life the U12 and X24 have 3-throw crankshafts (pistons are 120 degrees apart) and the 42-cyl has a 6-throw crankshaft. Those are a bit complex to do with Lego so I used simpler 2-throw cranks (180 degrees). Thus firing orders are not correct in those engines. Also the 42-cyl Zvezda M503 was done with radial-6s instead of the real life radial-7s because I couldn't find proper Lego parts for connecting pistons to the crankshaft. The Sherman 6046 U12 engine gearing and phase offset between the shafts were unknown to me so I just guessed them to be 1:1 and 90 degrees. In other ways the models should be correct (hopefully). The V8 has a flat-plane crank that were used in Formula One engines. Lotus 46 H16 flat-plane crank, gearing and phase between the shafts should be correct according to the schema image I found (shown in the video). The U12 has both crankshafts rotating to the same direction as was explained in mapleleafup forum.

Épisode 52 - Do Lego Wheels Spin FASTER in Vacuum?
30 octobre 2021
I tested a few different Lego wheels in 70% vacuum. Enjoy! The answer to the title question: Yes in general, but it depends on the wheel size and balance. The best speed improvement was from 5100 RPM to 7000 RPM which is a 40% increase. Some wheels didn't gain much as they started to vibrate in high speeds. The smallest Lego wheel didn't spin any faster in vacuum.
Épisode 53 - Making Lego Car CROSS Gaps
