Wearable Mechanical Butterfly Wings

I have half an idea of how to make the wings on my daughter's fairy costume work. My ideas involve vairying degrees of a pulley system, springs or rubberbands, and kite string. Any ideas of how to connect the pieces -or alltogether better ideas- would be greatly appreciated.

Should I make an instructable for this?

I made a mechanical Iris a while back and i am wondering, should i make an instructable for it? It is self-contained, and I made a strap for a monocle. It is unfortunately at my school right now, during spring break, so I cant make it this week. I am just wondering about your thoughts if I should do it or not.

Need help

Looking for help with my new project. I want to power my mechanical arm using hydraulics.  I would prefer to use a joystick controller.  I want this arm to be able to hold a hedge cutting machine. The arm will have the same freedom of movement as a human arm. Eventually I want to use this arm on a machine such as a bobcat or similar device. For now I just need to be able to power this arm and then I can go from there. Anyone up for a challenge???? Dave Sender my E-mail  mrdavesender@gmail.com Please see the photo of the size of the arm I'm looking to power.

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!

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

child's DIY mechanical toy panel

Once upon a time I saw a panel that had a light switch, receptacle and plug, screen door hinge and latch and other things a child could do to keep busy and learn while they are playing. Do you have any ideas of things we could add to the panel. It will not be electrified but could have some battery operated things. Something that makes sounds would be nice too.  This child is two and seems very interested in stuff like this.

mechanical wave

I'm trying to build a tail of a fake animal, and the tail is kinda long (total length of about 3 feet), I have a 10 pound pull solenoid and I want the tail to kind of do a wave thing, like if you were do a wave with your arms ( not in a group, all by yourself where you hold your hands together, you know what I'm talking about). I know how to do the electronic part of it by sending pulses to the solenoid, but How would I convert that into a believable tail?

Is anyone skilled in metallurgical engineering?

*Yes, I know, another question involving college and my future life.*I am kind of split between mechanical engineer and metallurgical engineer. They both have some great benefits and trades that I'd love to go into, but it's difficult deciding which would be better for me.I do aspire, no matter what field I go into, to weld and do other metalworking, although I don't just want to weld for people. I know it sounds weird, but I like to take the time to know about what I am working on, and not work at "face value", if you will.So, any mechanical or metallurgical engineers who want to try to sway me one way or another, please do so now. ;-) Thanks,Bran.

Mechanical washing machine.

I work for a charity with Aboriginal Australians in the remote outback of Australia, a place called Arnhem land, it is worth a google. People need washing machines, they buy them, they break , even with warranty cover, they can not be fixed as no service men will come here to service them, we are too remote.  Houses here have about 20 people living in them, there is no work here and people live on small government payments which are not enough to cover daily expenses. Due to the difficulty in accquiring and maintaining a working washing machine, health issues such as Crusted Scabies have taken hold here, and cause much suffering. We can't erradicate the disease here without getting working washing machines. We need a solution, an easy to use, easy to fix washing machine. No electronics. Cold water only is fine. Possibly even hand operated, or wind operated (or other)  I found one which is a plastic  tub which turns with a handle and stands on two feet.  However the construction too flimsy, the tub not big enough for a bed sheet, it was green though. Didn't use electric power. Anyone have any ideas? Know any other sites I could post on to get ideas? Thanks : )

Building a liquid monitor box help

Hello. I have little experience with these things so I am seeking help here. I have a prototype design for a liquid drop monitor. There is a tube that drip liquid and be detected by a photodiode hooked up to an Arduino. My question is about how to build an enclosure for it subject to my requirements. If anyone has advice for any of my needs below, the help would be much appreciated. I am not very knowledgeable of these kind of things. The circuit is in in two parts on two small breadboards, the detector on one side and an LED on the other. A tube will go through the box vertically from top to bottom. The box will be made out of acrylic because it's cheap, see-through, and I have access to a laser cutter. First question, how can I mount these breadboards in the acrylic box in such a way that I can remove them when needed or later replace them with a PCB later. Second, what sort of mechanical device can I use to adjust the distance between the LED and the detector? Essentially, I just need to be able to move the LED towards and away from the detector in one dimension. Third, I will need to change out the tube often to adjust the thickness. How could I allow for adjustable sizes? If the tube hole is the same size then I will only be able to fit one. Alternately, I could move the detector and LED horizontally to select different tubes. Is there a mechanical device for this? Fourth, I'm using acrylic because it's cheap and I have access to a laser cutter, but most designs for boxes I've seen are not made to be opened. I will need to be removing and rewiring things often. So is there a common or easy way of making/mounting a hinged acrylic door or a removable top? I apologize for the simplicity of my questions, but I really could use the help. Thanks!

Variable height desk: replace hand-crank with some kind of electrical motor

Hi, First time poster here, sorry if I'm misplacing this. I have near zero knowledge of engines, though I understand physics, at least from my civil engineering college years. I bought a variable height desk from IKEA (Skarsta model), which has a 12cm radius hand crank (see photos) that ends in a hexagon shape, h=6mm (so diameter around 6,93mm). This hand crank works fairly easily, needing little effort to crank the table up, with ~45kg of weight on it (it's supposed to go up to 50kg). So basically I was thinking if there was a easy, cheap and safe way of automating this with some sort of electric motor (I even looked up those Lego Technic motors!). Any suggestions? Thanks

Need help to design mechanical mechanism

Hello everyone, I want to create feeder cart with seperate section, that will be hangin on rails.  Feeder cart will have four positions: First one (First load) will be bottom gates closed, middle gates open to the top. 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.

Convert Crayons into 2mm+ Leads Like Graphite Lead

Hello! I want to recycle crayons and thought of converting them into 2mm lead or larger in diameter (since there’s only a certain thickness where crayons can be sturdy). I also thought the crayons should be mixed with something since they’re wax. I was thinking of buying a silicone mold rubber to make a mold (may make the lead bend since it’s flexible but easy to remove), a polyurethane mold rubber, or a protruder like the old fashioned way. Silicone mold rubber is expensive ($30+). I originally thought of it as a craft, but it’s too complicated for a craft. Thank you for your time!

Need Advice: Push a Button Get an Alert on Mobile Phone

Hi all, I'm attempting something "techy" for the first time and need a bit of help getting started, or deciding if this is possible. I'm trying to create something that will send an alert to a mobile phone if a button on another device is pushed. I'm fairly confident this is possible, but not sure what technology I could use to achieve this. I bought an Amazon Dash button to play with but not sure if that makes sense.  A rough idea of what I'm trying to achieve: If the Amazon Dash button is pushed and HELD for more than 5 seconds, the phone it's linked to would display an alert message or sound (preferably until the button is released). The button and the phone would be located in the same room. Does that sound feasible? What are some components/skills I would need to gather/learn for this project? Massive thanks for the help!

Mechanical Logic Gates, got some of your own design?

ADHD version at the bottom =========================================== I've been fascinated by logic gates and how they're used for quite a while now, and then I thought, "why not mechanical logic gates?". After a few brief searches on trusty ol' Google, there aren't exactly "a lot" of sources from which to draw from. I've designed a few (rudimentary) mechanical logic components myself, such as an AND gate and an OR gate (I was gonna do a negated IMPLIES gate, but I came up with the idea during Biology class, so that's pretty much gone now). The thing with electronic logic gates is that they are standardized (kinda), which makes building logic circuits easy, because you wouldn't have to build hundreds of different designs of the same logic gate just for that circuit, alone. Maybe some of you have some logic gate designs to share? Maybe we could standardize some mechanical logic gates and someone might just make a cardboard computer out of 'em :D Just to add, I am aware of the usage of weights, balls, gears, linkages, and lever-type systems for mechanical logic. We can come up with a few for each type, I guess. (this excludes fluidics, the use of water and/or air for logical computation) Yes, I have searched instructables, but even then, not a lot of sources (though some are quite fantastic, might I add). ============================================= ADHD version: Got some ideas for mechanical logic gates? Maybe we can standardize them, somehow :D

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.)

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.

Hi everyone, It's my first time posting to this forum, so I hope I'm posting in the right section. Please go easy on me: ) I'm looking to make a genie costume similar to ModMischief's awesome construction. That is her costume pictured below. I have not made the carpet section yet, so it can be altered to fit any plans for what I am trying to accomplish. https://www.instructables.com/id/Genie-on-a-Flying-Carpet/ I would like the flying carpet to be a little different though. I am trying to create a simple mechanism that will give the carpet some movement. I want it to mimic the up/down wave motion as if the carpet is actually flying mid air. Can anyone suggest something that would get me going in the right direction for ideas? I will have a 2nd person with me that could assist me once the costume is on, if there is some kind of crank mechanism that would work. Any ideas are appreciated!
