Electromagnetic Pendulum Clock

I agree, good luck.

si, secondo me c'è qualcosa che non va , probabilmente nel progetto oppure no, non ho esperienza per queste cose, ma mi sembra di avere capito che non è colpa dei braccetti stabilizzatori ma di un'altra cosa, il braccetto serve per portare avanti lingranaggio ad ogni Tic, ma per il mio problema che in un certo punto lingranaggio prende velocità e fa saltare il passo deve essere un'altra cosa che non capisco, potrei provare a spessorare di più gli ingranaggi in modo che siano meno ballerini non saprei …..

I noticed on every complete turn of the back gear that the pawls control ing the gear seems to slow down For a few ticks. Probably due to friction or an imbalance somewhere. I haven’t even tried adjusting the time yet. I want to give the clock a few weeks to settle in. I’ll probably take the clock apart in several more weeks to clean the bearings, and make sure nothing is binding anywhere. It just take time to get this thing running good. Remember, it Steve’s latest design, and who knows, he may end up tweaking it again. Enjoy the experience

I just wanted to know if that dragging you see in the video is about adjusting the arms or if it's another problem ... ..

ok, the strange thing is that for 70% of the turn that the gears make, the pawls keep pace, then the gears arrive in a certain position that they lose pace, as if at that point they are not balanced well and descend quickly ... ..., if you tell me that my problem and the defect it causes me in the video I sent you is to choose the exact configuration of the pawls, then I will try them all

You have to learn yourself what each adjustment of the arms do before you can come up with the best combination of pawl sizes and positions. So, try all combinations to learn how they work. It’s a tedious process.

I try, but in my opinion it seems that there is some gear as ovalized, when it arrives at a certain point it jumps 5/6 teeth all at once ……., I don't understand why… ..

Just start with each of the pawl, static and active. Try each combination, moving them up and down the pendulum arm until you find the best fit. Ones that do not slip, and always proceeds to the next gear tooth correctly.

It take some time to do this, but you will eventually find a combination that works The best. Good luck. You will feel proud when it is all working.

no Steve, the is not working yet, I still have to make the connections with the electromagnet, when you saw the video it was an example where I was telling you if you could show me a video of the operation that the ratchets should do, to realize how they must work.

hi Steve, can you make me a short video, of how to shoot the ratchets that I show you in the video?, I would like to realize how they must work. thank you.

ok Steve, I will lengthen the holes with tip to recommend, thanks.

to me it seems to have mounted correctly, yes the screw above is tightened well, I remind you that I printed the smaller version for the Prusa mini +, it seems to me that the three harmonic wires of 1,5 x95 mm, are too long, I should shorten them to 90 mm, then the two frames shrink, or as Steve says I have to add shims, but it seems strange to me that there is such an accentuated play.

ok thank you very much for your reply, I seemed to have understood in the Stive instructions that you could adjust the static and dynamic pawl empty with only the central gears as I showed in the video, at this point I did not understand well, I struggle, I have to translate the language.

I'll wait for the movement to come to try everything.,

Hi Steve, I didn't understand much for the adjustment of the active and static pawl, I used the shorter active pawl and the shorter static pawl I wanted to know if you think it is okay, please see the video,

wouldn't you have a video to show me how well these pawl fit?. a thousand thanks.

pensi che anche se da errore, riesca ugualmente a stampare il pezzo ?.

ok thanks a lot Steve.

I also wanted to ask you, when do you think the editing videos are ready. thank you.

Thanks

I also wanted to ask you, when do you think the editing videos are ready.

Thanks so much.

Maximilian.

per quanto riguarda l'orologio elettromagnetico, sto stampando le parti, anche questo progetto è fantastico !!!,

ti volevo chiedere, se preferisci stampare per questo orologio gli ingranaggi a interferenza, o gli ingranaggi che sono bloccati con le viti?,

quale delle due opzioni mi consigli ?.

Hi Steve,

Meanwhile, I congratulate you because the watch you designed the 32 days model is fantastic and perfect, you have studied beautiful and functional projects. compliments !!!

ah ok steven, now I understand, not having the mechanism I didn't understand. thank you.

I made a sketch of the magnets if they are to be glued like this, 1 or 2. thanks.

OK thank you.

Steven, I don't understand correctly, I come from Italy and I have to translate the words, the second hand with which configuration is it better to print it, 30% fill, 4 or 5 layers?, Upper 7 and lower 6 perimeters?.

Hi Steve, right now I'm printing the first piece, mini-landslides-Back-left, 😉, updates will follow. thank you. Maximilian.

Ordered my quartz movement from to different Chinese vendors. We’ll see which gets here first. I’ll be adding sound to my clock.

Hi Steve,

tomorrow I start to print the frame,

congratulations you did a great job,

I await the editing videos, when do you think they are ready?.

Thanks so much.

Maximilian.

Hi Massimiliano, I live in Australia so delivery times maybe slightly different, however, all of these pendulum parts come from China. Shipping from China always seems to take a while. Unless you can find someone local (in Europe) that resells this item, unfortunately, you are in for a wait. I purchased 4 of the pendulums on the 20th of December and am still waiting for delivery which is scheduled for early March.

Hi, any of you have any links where the pendulum movement arrives within a month?, Because from the link you gave me, the delivery is scheduled between March 22nd to May, it is very long as delivery .......

Hi Steve,

Many thanks for the design. The first gear is on the printer as I write this.

Hi Steve, thank you very much, as soon as the files are available, it was a good thing that you were able to design the model for the Prusa mini too, so users have more choice.

Hi Steve, I would like to take the pendulum movement, could this model fit for making the magnetic clock?

I will post here when the files are published. You might get a message by following me at myminifactory.

Steve, when you publish the smaller version magnetic watch, do I get a message from MyMiniFactory, or do I have to look at it every now and then if you've published it? thank you very much for your cooperation and patience.

The dark purple is generic silk PLA from Amazon. The light purple is from MatterHackers. All the brands I use are in the range of US$20-25 per kg. Inland has a really bright colored purple silk that I may try next.

Steve, I wanted to ask you what brand of Silk filament do you use?, I really like the gears you made, the two purple ones, the magnetic clock, I would like to make the light purple gears like you did silk. thank you.

Hi Steve, ok it's beautiful, I look forward to the release of the model for mini, we hope everything goes well and that there are no problems in the test you have to do. Thank you very much for redesigning a new model for mini. When the model for Mini comes out, will I be notified with a message or do I have to go and look at MyMiniFactory every now and then?

Hi Maximilian,

It looks feasible to split the frame for the mini. The dial will be a 177.8mm (7.0") circle. You have to turn off the skirt or reduce the distance to 0.7mm. This gives the largest possible dial without upsetting the gear train. Hopefully, there are not many 3D printers with a 175x175 print area, because it won't fit.

It should be released in about a week. I would like to print a copy to test it. And the assembly guide needs a new section with the updates.

Here is a CAD image showing the mini clock on the right. The pendulum and gears are unchanged, just slightly more visible with the smaller dial.

Steve

Steve, do you think in a week that is Friday, next Saturday that you can tell me if the magnetic watch is suitable for a Prusa mini?, Why should I give a gift, otherwise I will take the model with Arduino nano, but it is more complex… thank you very much.

steve, cut the clock frame with prusa slicer and glue it with epoxy glue, do you think it can be done?

I am very sorry not to print this watch, the model with Arduino mini can I print it with the prusa mini?

Hi Steve,

when i wanted to know if you finished the electromagnetic clock, i would like to do it and buy the stl, can i print it with the Prusa Mini too?.

Thank you.

The electromagnetic clock is nearly ready to be released. I am nearly finished writing the assembly manual. I still have some minor fine tuning for the ratchet arms. It should be published within 1-2 weeks.

The electromagnetic clock will be a lot easier to build for most people. The pendulum driver module used to power it is available for around US$4. Preliminary current measurements estimate that a run time of over 1 year should be possible. The stepper motor clock needs a special stepper motor, an Arduino Nano, and a custom motor driver circuit.

Hi Steve, when do you think to finish the electromagnetic clock?, I was interested in this and the other model with arduino, I am a bit undecided between the two models, which one do you recommend?, Arduino or electromagnetic?.

Thank you.

Good to hear Steve, enjoy building your creations.
