Creating a crank operated switch that you can keep spinning indefinitely. Answered

The idea is to have a rotary switch connected to a crank so that when the switch is turned on you can keep on spinning the crank and it won't utterly destroy the switch, also you could do the same backwards, spinning the crank in the other direction so the switch turns off, but you can keep spinning it without it damaging the switch. I can't really find a simple way to do it though, since I'm very inexperienced. Additionally, I would love suggestions to make the crank feel "heavier", like those emergency crank flash lights.

Hand Crank Music Machine

Does anyone know about these small music boxes that play music? If you seen one, they're these small things that play notes in a looped sequence using small metal plates (kind of like a finger piano). Can anyone try to make something like that? Sorry for the small details if anyone's confused.

Is there anyway to fix stripped crank arms?

Well I was riding my fixed gear and my right crank arm got stripped. I don't really want to buy a new one but if it's necessary I will get a new set. Is there anyway I can fix it so I don't have to buy a new crank arm set?

I'm looking for a simple way to raise/lower an existing desk for seated/standing pc work.

This is the closest thing I've found yet: I have been tinkering with a crank/cable idea, maybe counter-weighted; nothing good yet.  It has to raise/lower about 18 inches smoothly and with good stability.  Manual cranking is preferred - electric motors or hydraulics seem too complex/expensive.  Thanks! Just uploaded a photo of the desk. One more note - if I were stating from scratch, I might look at one of these:  But I like this desk, just want a bit more flexibility (maybe even slide a treadmill under one day if I can raise it even further)

How can I block a person from calling me?

Someone keeps crank calling us.  They did it 10 times in a row the last time.  When we hung up, they called us again 5 seconds later.  However, we can't block the number because whoever is calling us turned off their caller ID, so all we see is "Unknown name, unknown number".  Do you guys have any ideas?  This is pissing me off really bad!

Hi! I would like to make a hand crank cell phone charger....

Hi everybody, How would I make a hand crank cell phone charger from scratch (meaning, not just taking a hand crank flashlight and rigging it to charge a phone). I would really like to understand the electronics behind it all. I think this would be extremely useful if my phone died and I had no outlet available. I know I'd have to use a small motor, but how many volts? amps? etc. Thank you so much! patti :)

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

What's the legit way to fix a crooked unicycle crank? Answered

I bought a unicycle off craigslist and I was riding it around. my foot slipped off the pedal, leading to a fairly nasty crash (I landed on my feet, the unicycle was the nasty part). when I picked it up, the crank was off by about ten degrees. I couldn't find any instructions on how to fix such an issue, so I just figured that if I hit it into that position I could just hit it back. I smacked it with a rubber mallet a bunch and it eventually made its way back to the right position. I'm now wondering why it was possible to just smack it to where it needed to be (seeing as I doubt a unicycle would have any pressure-fitted parts, especially since it's a sun unicycle AKA legit), and what the correct way (if this isn't the correct way) to fix it would have been. oh, and if it helps, the crank on the unicycle was also crooked before I hit it,  as in the inner surface of the crank wasn't parallel to the tire until I put it back. (sorry this is in the bikes channel, I guess the instructables sorting system isn't that diverse yet. I kid, I kid.)

Yarn Cone Winder Please!

There's a great instructable for a center-pull yarn winder: I'm looking to build something that winds yarn or twine onto a cardboard cone like this. I know electric ones exist and the way they work seems pretty simple, I just know that there has to be a way to build a cheap hand crank one. Here are some videos showing how the electric one works:;=related It seems that the major necessary components are: 1. something to spin the cone 2. something that moves back and forth along the cone so it winds evenly and 3. something to keep the right tension. Can anyone point me in the right direction? Or make a full instructable? I challenge you!

How do old-fashioned hand-crank telephones work? Answered

I was wondering how old fashioned hand crank phones work, in particular: Does the cranking provide power to the phone, or does it just ring the bell on the other end? I always thought that the cranking rang the bell on the other end of the line, and that the phone itself used a transformer to amplify the input from the microphone, without using power? Also, how do duplex coils keep the user from hearing their own voice through the speaker? Thanks!

What circuit for an Hand Cranked Led Torch? Answered

Hi all Instructables! I follow a lot this site and now i hava a little project to do. I want to build a Led torch that is charged using a DC motor and a couple of High Capacity Capacitors. The problem is that i'm not very good with electronics (i've made a chemistry school) but i really like it. So, what kind of circuit i have to use for something like this? I use a Dc motor that have about 4.5V output, the led are standard white ones, 3.5V 30mA. Some friends told me to use an LM1086 voltage regulator that have the output with the capacitors, other say to use only a rectifier diode, other say that i have to use a Led Driver (but i think it is useful for big one, not mine...) My goal is to make the circuit very relyable, but not impossible to make and that make the Led well balanced, good brightness/consume ratio... Thank you!

I want to power a 4W 30V lamp with a battery that charges by a dynamo/hand crank generator.How can I do this?

I want to power a 4W 30V lamp with a battery that charges by a dynamo/hand crank generator. For batteries, I want to use something like 3.7 V standard phone batteries, or may be camera batteries etc. I understand that I have to use a few phone batteries to get a decent amount of voltage which I can then step up to 30V to power my lamp. How can I go about doing this? How would you suggest to connect the batteries, and what kind of circuitry (buck/boost regulator, voltage step up, RC circuit etc. ) between the battery and lamp do you think is the best to use for outputting the right voltage? Thanks a bunch! :)

Help (advice) with building a braiding machine?

I've been working with braiding plastic shopping bag strips into rope, and by hand it's a slow and tedious process.  I know that braiding machines have been around for ages, so the patent on many of them has to have elapsed.  I've Google'd and Bing'd and Yahoo'd my heart out looking for how to build a simple one to no avail.  The only thing that comes back is Chinese sellers of a commercial braiding machine. All I want is something that I can build, a hand crank mechanical kind, that can braid 7-10 strands into a larger rope. It doesn't even have to go fast, in fact I'm fine with it being slow. Can anyone provide plans for one? UPDATE: Ok so I think I have plans, but now I could use some advice with how to go about fabricating the sprockets.  One idea is to purchase a premade sprocket and modify it, then use it as a master for a mold to create more.  I was thinking of either doing the whole dissolving styrofoam with Acetone then pouring the plastic in the mold thing, or possibly adapt the Oogoo instructable.  Thoughts?? Update 2:  My latest brainstorm leaves me thinking that I could use a bicycle sprocket (gear) as a master and then make a mold from it, then make duplicates from the mold.  Thoughts???

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.

Advice for a hand crank ice cream maker please? Answered

I'm thinking of making a hand crank ice cream maker using an old hand drill I had and mounting that on a plastic bucket that'll be my ice bucket, then using some copper pipe I have lying around and soldering a dasher with some oak scrapers for the side.

I'm wondering if I could safely use galvanized ducting, I'm planning to make sherbet on this as well, so will the acids react with it at all or is there some other hazard I should know about using ducting for this?

What kind of diode(s) do I need?

I am trying to make a device that uses a dynamo. (hand crank) The dynamo when cranking produces up to 12v which I want to use to charge a battery. The problem I'm having is that the current goes both ways. When I'm not cranking the dynamo, the battery turns the dynamo. I need to make the current only go one way, only towards the battery. From what I understand, I need a diode. The problem is, what kind of diode, and how do I wire it in my circuit? Any help would be much appreciated.?

Slow-discharge circuit for gradually diminishing electromagnet field?

As I understand electromagnets, you wrap a wire coil around an iron rod and run current through the coil. As long as there's current going through the coil, you have a magnet... But when you cut the current, no more magnetism... I want to create a circuit in which a hand crank charges up one or more batteries or capacitors, which in turn discharge slowly through an electromagnetic coil (such that the magnetic field of the electromagnet gradually diminishes) over the course of an hour or so. The overall idea is that you crank the crank for a short while, creating a magnetic field so that BBs cling to the electromagnet. But little by little, over the course of maybe 20 or 30 minutes (longer would be OK), the BBs drop off one by one (or a few at a time). Can anyone suggest what such a circuit might look like? What variables will determine how long the crank has to be turned, how strong the magnetic field will be and how slowly it will discharge? And will the BBs only cling to the ends of the electromagnet? Or will they cling along the length of it as well?
