ludov Posted December 23, 2017 Posted December 23, 2017 (edited) I have one of the old pull-back motors, which, as @Aventador2004 noticed, unwind really, really fast. I quickly realised that if I wanted to build anything but a car, I needed something to let it unwind in a controlled manner. For example, an escapement, like in a clock. Unfortunately, @Didumos69 posted his topic while I was working on my proof-of-concept. I guess there's no rule against having the same idea, but I'll think about if I want to build a clock or something else from it Anyway: here's a proof-of-concept to show that the idea works. I shamelessly borrowed one of Ben van de Waals escapements (W40, https://www.youtube.com/watch?v=e-dXJJ-aJ60), which works great. Now to figure out a ratchet mechanism to wind it. To be continued PS: sorry for the filming-through-a-vertical-mailbox-opening, but my phone was the quickest way to get a quick video and I still don't know how to use it properly If anyone can tell me how to change the aspect ratio on the iPhone, let me know.

Rudivdk Posted December 23, 2017 Posted December 23, 2017 Cool, another non-typical pullback implementation. This is gonna be an interesting contest for sure. Mechanism works nice, looking forward to see where this will end up. Good luck in contest! Quote
ludov Posted December 23, 2017 Author Posted December 23, 2017 Thanks, @Rudivdk I now also have a ratchet that allows to wind up the pull-back. Accidentally, I reversed the gear direction (due to the differential). It still seems to work, but I think the other direction works better. Now to figure what to do with this concept... Clock or something else... Quote
Aventador2004 Posted December 23, 2017 Posted December 23, 2017 Good work, simple mechanisms are easier to make, and mostly work better. Quote
mocbuild101 Posted December 23, 2017 Posted December 23, 2017 Nice work, the escapement works well, I'm just waiting to see what you do with it.... 1 hour ago, Ludo Visser said: If anyone can tell me how to change the aspect ratio on the iPhone, let me know. You should be able to change it just by holding it horizontally. Quote

I guess there's no rule against having the same idea, but I'll think about if I want to build a clock or something else from it You will have to figure out what to use it for, for yourself of course, but I wouldn't mind you making a clock too. We have to see whether I will make it to the finish line and it would be a pitty if you would regret not making a clock afterwards. Good luck with this and I will sure be following your next steps.

ludov Posted January 14, 2018 Author Posted January 14, 2018 So... I thought about a lot of ideas. Chess-clock, jack-in-the-box, etc. Finally, I came up with... a clock I tried something else: a mix of a digital and analog clock, so I could incorporate a lot of different mechanisms. Let's say it's "art deco" The large number on the left is supposed to be the hour indicator. It's driven by a Geneva drive in the back of the clock. On the right are the minutes (long hand) and seconds (short hand). There's 4 minutes in an hour and 3 seconds in a minute. Doesn't make a lot of sense, but all the mechanisms require quite a bit of power and with more gearing I had to wind up the pullback multiple times to complete an "hour". The current gearing is a trade-off for visual appeal In between the "hours" and the "minutes/seconds" is another second indicator that is supposed to be reminiscent of those found on digital clocks. It's driven by a Scotch yoke. Technically everything works, as you can see in the video. The "packaging" needs some work though, but I have some time left, I learned. What do you guys think? Any suggestions for finishing the housing? Quote
Aventador2004 Posted January 14, 2018 Posted January 14, 2018 Nice, not sure about ideas for housing though... Quote
mocbuild101 Posted January 15, 2018 Posted January 15, 2018 Looks great! ...or should I say, it looks horrible, but it works great! Not really sure what's best for a housing - especially with that big turning part... (which, by the way, is very cleverly built) Quote
Didumos69 Posted January 15, 2018 Posted January 15, 2018 This has turned into something very creative! As for the housing, you could make it even more steam punk. Perhaps also add something that makes more noise. Quote
ludov Posted January 20, 2018 Author Posted January 20, 2018 I like @Didumos69 suggestions for the steampunk theme. I'm not very good at styling things, but I gave it a shot. What do you guys think? (sorry for the bad lighting in the photo's... it's quite dark here) Quote
BrickbyBrickTechnic Posted January 20, 2018 Posted January 20, 2018 Awesome, but you are missing gold and brown, 2 prominent steampunk colors. Quote
Didumos69 Posted January 21, 2018 Posted January 21, 2018 I like it! Using gold and brown would be better, but I suppose you used the colors you had available. Despite the colors I thinks this fits the clock better than 'art deco'. Quote
Victor Imaginator Posted January 21, 2018 Posted January 21, 2018 Wow, cool design) I like that steampunk idea. Agreed with gold/brown colors - not necessary, but will fit better. Quote
ludov Posted January 21, 2018 Author Posted January 21, 2018 Good point regarding the gold and brown... I don't think I have any gold parts, but I'll check. I have a few brown parts that I might be able to use. Thanks for the feedback! Quote
ludov Posted January 21, 2018 Author Posted January 21, 2018 I found a few brown pieces from a Creator set I once bought... Is this the direction to go with, or I'm I doing it all wrong? Quote
BrickbyBrickTechnic Posted January 21, 2018 Posted January 21, 2018 Perhaps a bit less randomly arranged? Quote
Davidz90 Posted January 21, 2018 Posted January 21, 2018 I think that the semi-random arrangement is very cool. Some additional mechanism, such a chime, would fit this perfectly! Quote
ludov Posted January 22, 2018 Author Posted January 22, 2018 I think I know what @BrickbyBrickTechnic means: I kind of tack stuff on there to add some color. I try again, your comments again much appreciated, of course! Quote
Didumos69 Posted January 23, 2018 Posted January 23, 2018 This is starting to look better and better. Somehow the blue barrel is out of tone now. I would like to 'hear' the clock . Quote

I would like to 'hear' the clock . You're right about the mismatch of the blue. I was thinking the same, but I don't have a white one. But then I realised that 8868 has some nice tanks Fits nicely, I think: There's a video a few posts up that has the mechanism with sound; it hasn't changed since, only aesthetics. I think that this will be my final submission: make some nice photo's and a video in the weekend and I'm just in time Edited January 24, 2018 by Ludo Visser Quote
zweihander Posted January 25, 2018 Posted January 25, 2018 nice, white tank looks a whole lot better with the rest of the build! Quote
