  1. Hello everyone ! So I spent 1 month building an entirely functionnal Kit-Cat Clock with Studio. It's not totally finished yet because I would l'll need to buy the parts on Bricklink for making it IRL, but it's theorically viable. I already submitted the project on Ideas and will update the design as soon as I buy the pieces. Do you guys have any tips on the mechanism for making it more reliable ? If you are interested you can support my project here ;)

    Happy Hourglass

    My latest MOC, “Happy Hourglass,” was built for Eurobricks’ collaboration, “Potion Shoppe,” displayed at Brickworld Chicago 2019. This project was originally planned as a time realm for Eurobricks’ world tree the prior year, but since I couldn’t make the trip, I repurposed the gears and clock face as a fanciful glockenspiel-style grandfather clock. As usual, the final design weighed in heavier than anyone anticipated, so the table underneath was designed and built last. For the tabletop, I sandwiched 2 layers of 4x (32x32) Technic brick grids originally planned as risers for my plot of land in Happy Mountain (EB BW17). The result was quite indestructible, as it didn’t sag a bit! For the table legs, I modified the poles from my River Wheel, filling the hollow center with perpendicular Technic bricks. The gears in both the turntable and clock face are another iteration of the high-torque gears from the River Wheel, this time adding 4 planetary gears inside the 11x11 Technic arches. Unfortunately, the 11x11 quarter circles don’t rotate smoothly when driven with 4 gears, since the driving gears all pass over the gaps simultaneously, leading to an eccentric, jerky motion. This led to frequent questions whether the hourglass had stopped working happily, only to be proven otherwise when it’d restart untouched within moments. As they say, there’s no stopping time! Happy Hourglass and the Potion Shoppe (topic and pictures soon forthcoming) won Best Mechanical and Best Group Display, respectively, at Brickworld Chicago 2019.

  4. I have always wanted the original 4757 Hogwarts Castle because it had a clock and a pendulum! I found its clock works to be a GREAT mystery until I could look into its instruction manual! Lego was so gracious to create the new Clock Tower and release it! I loved it very much. However, a great feature was missing: the pendulum! I decided to make minimal modifications for adding a pendulum and even motorizing it! My Clock Tower's clock work would not be a GREAT mystery because I made a video which showed how I built it!
  5. THE CLOCK TOWER Hi guys, finally here we have this MOC that I have been working on during months. This Diorama represents from the left to de right; The Whomping Willow, the Stone Circle entrance that connects to the Wooden Bridge that I have omitted for space reasons in this MOC, and Hagrid’s Hut. In the Back we have the section of Hogwarts that represents the Gryffindor Tower, the Clock Tower and also the North Tower, where the Divination classroom is located. After the completion of my last MOC, I decided that from then on each MOC that made the Hogwarts Castle would be based only on one or two films in order to recreate them as completely as possible. Because the clock tower is a new section in the Azkaban prisoner film, I decided to focus on this film, but when LEGO released the new Harry Potter sets I finally dedicated the castle to the first three Harry Potter films, thus recreating the final scenes of the philosopher's stone and the secret chamber.

  6. A compact, gravity powered clock. There are many Lego clocks around, but most of them are really huge contraptions, and for a good reason. They are easier to tune, more eficient, work longer... So naturally I took a challenge to make something small but still usefull :P. The key component is the pendulum. Typically, a significant length is needed to get period of one second. Here, a second mass over the pivot point slows the tiny pendulum down, so that it can be many times shorter than usual. The compact "knife edge" pendulum suspension dramatically reduces friction, decreasing the power necessary to run the piece. The low mass of components creates many problems. The clock is reasonably accurate (I got it within 5 seconds per hour), but tuning was a nightmare, and even a sneeze can alter its rate. The power source is 100g weight on a string. Due to only one hour working time, I have decided to use only minute hand. Seconds hand puts too much power demand on the mechanism. 1 by David_Z1, on Flickr 3 by David_Z1, on Flickr Schem2 by David_Z1, on Flickr Many thanks for KEvronista for inspiration to get into this Lego clockmaking hobby :) [EDIT]: embedded the video.
  7. Hi, My name is Lenka and I'm from Czech Republic. I'm going to ask you to consider supporting my Lego Ideas project - Astronomical Clock. We actually have astronomical clock in my hometown of Olomouc, but my LEGO astronomical clock is inspired by the one in Prague. What makes it cool? It's a minifig-scale build that can fit together with modular buildings and has a pretty neat functional mechanism (check out the update video!).
  8. This modular station was inspired by a long since expired Cuusso / Ideas project, (not mine), and set 2150 Train Station from 1996 while the clock tower is inspired by Big Bentley Bust-Out (from Cars 2 set 8639) from 2011. I added a removable six track long platform and put a luggage ramp from the street side for use by the wheelchair pieces LEGO recently made. By the way: the logo right below the clock is the official LEGO trains logo built in bricks, while the words in the center (just between the middle pillars) reads "Ironwood Union Depot" in printed 1 x 1 tiles. The street side of the station has been extended towards the edge of the base-plate, allowing for a more room (and more details!) inside the building. The year of the stations completion, 1928, is right above the main entryway. The lower floor has the central ticket desk, plus pizza restaurant (complete with opening oven!) on the right side with seating available on the left wing. These wings also allow for access to the platform under the twin canopies. The second floor has the switching control room and station managers office which floats inside the exterior walls on some tile-topped pillars. This assembly is barely connected to the build by two studs. (NOTE: No stairs to the upper floor were made because that's how the official CITY sets are, so I didn't include any as I was going for an official LEGO set feel.) This a closeup of the four-sided clock tower and brick-built LEGO Trains logo. The modular station features two platform sections, two lower roof sections, one upper roof section, and the removable second floor on top of a cafe (with seating) on the lower level. The station platforms fit via Technic pins while the other sections attach via a few studs. EDIT 10/16/17: Added new pictures of the revised station. EDIT: 11/20/17: added revised photos in preparation for real life pictures come Christmas morning. EDIT 12/31/17: I just need two more letters and to cut up a 48 x 48 base-plate into 16 x 48 strips.... plus I need to build the platform on those strips. EDIT 1/5/17: it's finally DONE in real life! EDIT 3/19/18: Added clock tower and brick-built trains logos, plus revised interior details. Comments, questions and complaints are always welcome!
  9. Pentagon Clock This is a wind-up pendulum clock powered by two pullback motors. This clock is not true to real time but rather focuses on features such as a wind-up mechanism, pin wheel escapement and three concentric hands. It has been built completely in-system and can be reproduced without any fine-tuning, except for making all gears run smoothly of course (LXF-file here). The clock has a very consistent autonomy of 18 minutes. It features: A wind-up mechanism - A differential is used to prevent the hands from running counterclockwise when winding-up the clock. One of it's outputs is locked by default and slips during wind-up. Pin wheel escapement - Instead of using teeth, the escape wheel has three round pins that are stopped and released by a scissors-like anchor, which has been integrated in the pendulum. Three concentric hands - Planetary gears and a differential house make for a fictitious LEGO time system with 2 hours in a clock revolution, 5 minutes in an hour and 30 seconds in a minute. The pentagon-shaped clock face refers to the 5 minute hour. All features have been originally developed for this contest.
  10. I've built a few clocks with LEGO over a few years, but none of them have been practical to use. To be practical, it needs to run for at least 24 hours, and be really easy to rewind. Having to spend more than 10-20 seconds with a winding wheel is too much of a pain (and my last clock took way longer than that!). The main difference between this clock and my other clocks is the drive weight is on a chain, and the chain can be simply pulled back through the clock to rewind it (driving a ratchet instead of the drivetrain), solving the ease of rewinding problem. Some other details: The escapement is a Galileo escapement with a 40 tooth wheel The hands can be moved forward by hand to set the time via a differential ratchet The drive weight is ~600g (11 boat weights x 53g, plus the parts to hold it together), the chain is a loop connected to the bottom of the weight to balance the drive weight The ratio between the chain and the escapement is 416:1 (40:24, 2:1 differential, 40:8 x 3) The weight falls 2.59cm/hour, so with 3 feet of drop, the clock will run for about 35 hours (it's currently mounted a little over 5 feet off the floor, so it could be given enough chain to run for about 60 hours). It should be accurate to within a minute per 24 hours, but it will take some time to dial in the position of the bob on the pendulum The single thing that helps the most with efficiency is a knife edge suspension for the pendulum, I learned this technique (and probably other techniques too) from and Here's a video: And here's a slow motion video of the escapement: I hope you find it interesting! I wanted to share the chain drive technique because I haven't seen it before, and it really makes a LEGO clock a lot more fun and less of a pain in the butt than a string on a spool :)

    [WIP] LEGO Clock

    Hello Eurobrickfans. This is my first Forum post, so please forgive any netiquette errors. I am attempting to build a functional clock in LEGO. Progress is posted on my blog at (among other things I'm building). Here is a short Youtube of current progress: Thanks Justin
  12. This is a fully automatic clock that was finished end of 2014. So, why do I call it "fully automatic"? - The clockwork runs as a normal mechanical clock with a pendulum and counterweight. - There is a motor that winds the clock every hour. - The speed of the clock is adjusted once a day using the Mindstorms unit. The speed is adjusted by changing the length of the pendulum. In total, the clock runs for itself without any assistance, and it shows the right time, even if it is build using only LEGO bricks. (Apart from the string to the counterweight) There have been many challenges in this design. My main focus, except the obvious goal to make everything to work, was to make this as compact as possible. The whole clockwork fits inside 14x14x14 studs. I did a short video to show the "action": The two sensors are used for: 1. Stop when the counterweight is fully winded 2. Give feedback from the minute hand rotation back to the Mindstorms unit. The counterweight is made out of 12 train/boat weights and is about 0.68kg. Winding is done through a differential to avoid interruptions during the winding. There are two medium motors inside the clockwork for the winding and adjustment. The Mindstorms unit is hidden in the base behind a hatch: WIP pictures Specially designed differential gear to reduce the friction between the counterweight and clockwork as much as possible. The winding motor rotates the large turntable gear: Clockwork prototype, without any automation: Very first prototype of the escapement:

    MOC: B:TAS, The Clock King

    A creation based off of the episode “The Clock King” from Batman the Animated Series. I rather like the Clock King, and while his appearance in JLU Animated is cooler, he nonetheless is great in B:TAS too. I went for the gear look on this build like in the episode, and added in more clocks for looks. Unfortunately I had to change the “death torture” of Mayor Hill so I could include all three characters in the same scene. Anyways I’m glad with how it turned out. Enjoy ~Nemo
