Mechanism for mechanical timer

Hello everyone, My wife and I both feed the dog, but we're never sure whether the other's already done it or not.  (the food disappears pretty quickly)  I'd like to build a track with a slider that takes about 10 hours to slide from 'fed' at the top to 'not fed', and make it so that the slider is easy to slide back to the top. What immediately comes to mind is a counter weight escapement mechanism, but I though I'd hit up the brain trust to make sure there wasn't a simpler way to pull this off.  (I could also envision a timer chip hooked to a mechanical release, but I'd prefer to stay wholly mechanical for this one.) Many thanks!

Using "Phun" to simulate mechanisms

I'm not an engineer, and don't have access to Autodesk / AutoCAD, so I've been using Phun to simulate mechanical design.It's not strictly valid in an engineering sense, but it works pretty well for roughing out ideas. The polygons were created in Inkscape, then converted to Phun scenes with SVG2Phun. Some objects won't translate (like grouped objects), so it's necessary to simplify (hence the two images from Inkscape.)

Second (Second load) will  be bottom gates closed, middle gates have to be locked in horizontal position. Third  position (First unload) bottom gates open, middle gates have stay locked. Fourth position (Second unload) bottom gates open and middle gates also open, that stuff drops out. I want ask you advice how to design bottom and middle gates open, closing and locking mechanical mechanism (without any electronical parts). This feeder cart will be operating by one man.  I have created middle gates mechanism, but maybe you have better solution.  I really appreciate for any ideas. Sorry for my english mistakes.

Help make a quacking noise in a wooden toy duck (mechanically, not electronically)

I'm in the process of recreating the LEGO wooden duck toy. I'm only working from a few images I've found online, however; I don't have an actual one to examine. On the originals, the axles operated a couple of mechanisms: the duck head pivots to open and close the beak, and there's a mechanism under the base (I'm assuming) that makes a quacking noise. I've got a pretty good idea how to create a simple cam for the head/beak movement, but I'm not sure how to generate a quacking noise mechanically. My online searches have proved fruitless. Does anyone happen to have one of these vintage LEGO ducks and is willing to snap and share some photos of the mechanisms? Or, does anyone have any good ideas how to make a quacking noise mechanically? My thoughts are a push/pull rod-type crank attached to an axle, but on the other end of the rod . . . not sure.

Check out Christy Canida & Eric Wilhelm on Popular Mechanics website for the article: 25 Makers Who Are Reinventing the American Dream   "More than the work he did at MIT while earning a Ph.D. in mechanical engineering, it was his passion for kite surfing that led Wilhelm to create Instructables. Launched in 2005 with his wife, Christy, and colleagues at the design firm Squid Labs, the DIY website quickly became a forum for step-by-step instructions—the kind Wilhelm had been distributing to fans of his handmade boards and sails. The site, which was bought by Autodesk in 2011, now features more than 100,000 user-generated projects in fields from cooking to woodworking to electronics."

weird question - online source for smallish mechanical parts

Hey, I'm new here. I'm an established musician (composing is my focus).  I've gradually decided I'd like to work on a new composition project which involves electro-mechanical instruments of my own design. I have a decent understanding of electronics, and I don't think the mechanical designs will cause me too many problems.  I've had plenty of experience in building hobby stuff - remote controlled planes, etc. What I don't know much about is where to source mechanical parts.  Electronics, no probs.  But things like wee little cranks and levers, hinges, etc, etc... stuff I'd rather not build from scratch but you can't exactly find in a hardware store. Any ideas?  (I know this is off the wall). Many thanks! - Tom

OK, I finally got hold of measurements for theo's strandbeest. these come directly from theo himself which means there accurate however it also means they're not in English. the numbers are there and they're easy to figure out, but it would be nice to know what the paragraph beside them says. so if any can read it, please post a translation. thanks

Alternative clock-Mechanical

I need to build a device for a competition that can measure time acurate to the tenth of a second, but from its starting position it must be no more than 30cm in dimension, but can exceed that once it begins.  Even if you know of something that can do seconds that would be fantastic.  If you have any ideas or places to find plans please do tell.  IT CANNOT USE ELECTRICITY

Looking for Murphy bed frame/mechanism that works w/out a cabinet

Hey all, I'm looking to purchase a Murphy bed frame/mechanism w/out a cabinet. The only one I could find online was by a company in Canada (I'm in NYC) Here is a link to the frame on their site: I already have the mechanism from , which I received as a gift, but I think it would only work w/ a cabinet?? Is there any way to use the mechanism I have from wallbed w/out  a cabinet? Any other ideas or where I could find a frame/mechanism that would work w/out a cabinet? Or recommendation one someone in the NYC area who could help, including installation (paid of course)? Thanks

Sear Mechanisms

I have tried to build a sear system on some of my guns, but it is so hard! I built one that kind of worked but couldn't fit on my new rifle that i just made (i might post but has a block trigger right now). Who knows how to build one of these sears, and is it really worth it? What if a block trigger just works better?

Ember's Mechanical Designs are now Open-Source

We released the mechanical design files for the Autodesk Ember 3D printer in Fusion 360. Here's what I wrote about it on Ember's blog: The full design of Ember in Fusion 360 is now available for you to freely view, download, inspect and modify.  I've been having a blast with the explode model function! We're sharing these designs under a Creative Commons Attribution-ShareAlike license, the same license Arduino uses to share their design files. Just like the formulation for our resin, we're explicitly inviting you to understand, remix, and remake Ember.   Ember's Mechanical Designs are now Open-Source

Oooo, look what I came across today....

I was out and about today, going to local areas of interest, and we stopped at a little shop I hadn't been in for years. In amongst all the old tools, and bits of paraphernalia, were all these magazines (Popular Mechanics, Science and Mechanics, etc.) from the time of my youth. I was THRILLED, and so I started going through them. Well, I would have loved to have taken the whole box of them (about 50 or so) home with me, but at $3 a pop, I decided on just 2. The Popular Mechanics magazine from the year of my birth (not the month, this one was a Jan. issue). and the Science and Mechanics issue is from Aug. 1960. Neither is remarkable in any specific way (excepting the birth year one). At the same shop I also found an original copy of Gimbels Handy Book For Boys. © 1933I am thrilled at this find, not that it is terribly valuable as an investment, the cover - binding is not so good, but at $5, it has a treasure trove of info and tips, very similar to "The Boy Mechanic, yet different too.

Murphy style beds mechanism

Hey guys, I need some advice, I want to build a murphy style bed, in short i want the bed to look like so: I have build and tested the shelf.leg system, it works pretty well and is weighted out nicely. the concept is going to use pistons to lower the bed for a smoother feel but what my concern is what would be the best way to build the pivot mechanism at low cost but high durability. the bed will have a sofa at the front also but not like the one in the link, my version will be more of a box with cushion and fabrik that i can store items away into. Please use the link below to view a version of my concept for the pivot mechanism: ( i know there are a few misspelt words but it was just a quick mock up for you guys) Any help is welcome - just dont advise me to buy the murphy bed mechanism as its to expensive and i believe i can build the entire bed for the same price :)

Building a hand-crank mechanism driven turntable

Hi there, Hopefully one of you guys should be able to help me out with this! What I want to build is a a kind of a large scale music box, (you know the ones where you would turn the wheel and the ballerina would spin?). What I need to make is a hand cranked machanism which will turn light wooden disc. This should all be contained within a wooden box. Would it be easier to build this from scratch or to rip an existing mechanism and re-house it?

cardboard music through mechanic oscillation ?

Hi everyone, i'm planning to build a big cardboard instrument. if you look at the attached .png you will find a very simple drawing of what i have in mind. i have some experience in programming dc motors with an arduino, but im not that well learned in physically building things. the motor should be fairly strong, the cardboard size will range from 2 meters to half a meter. any tips in the right direction are welcome! greetings, Rogier
