Rotary input for a cellphone

I have an idea to do a total conversion on a cellphone, including things like a steam-driven charger, etc. The issue I am running into here is if I could, I'd want to make it rotary. I saw Randofo's PIC method for making it a USB input here but I have no clue in terms of how a cellphone works, or any of the chips involved. Sadly, my knowledge is mechanical, not circuitry. Any sort of ideas are welcome... please help me progress on what I hope to be my magnum opus of steampunkerie.

Solar Ipod, cellphone charger

Hey guys I found this tutorial for building a Solar Ipod charger http://yosemiteoutside.com/m/Blogs/02EA4A6B-8893-4F3E-87A8-C1E4B24C3AAB.htmlI have already looked up all the parts for it, but when reading the data sheet for the regulator http://www.st.com/stonline/books/pdf/docs/2146.pdfI was rather confused, I got that it could take up to 35v, but there was no max amperage ratings. I am thinking of making one that is more efficient using a solar panel that putts out more watts, because the one he used only put out .6Watts (100ma x 6v), but the regulator can put out 2.5 watt. couldn't you hook up a larger solar panel. Thanks

I wonder! how one would go about turning a cellphone steampunk?

Like most of us here at instructables.com I loves steampunk stuff for no real apparent reason. It might be considered over the top to my cellphone into one but trust me my cellphone needs help. Its ok and some would call it cute but muchas boring.(hand -me- down) I never use it but this year for school I shall have to and so i want something that will make me smile ( especially during the school year. Our school is very unsmiley). So something very cool. I'm thinking a lot of brashish and wood but something I could easily do. My cell phone is two parts and flips open from the middle if you would like pics I would be more than happy to post some, Thanks Steamie

Crazy Idea with Cellphone Batteries. Need an Experts input

My cell phone's battery doesn't last very long--less than 24 hours while I'm using it, and less than 48 on standby.  I'm getting a new battery for it, but based on what I've read about this phone on the Internet, it's just a battery hog, and the new battery likely won't help much. So my thought was "what if I put TWO batteries in there?"  Crazy, right?  I mean, I can't actually fit two batteries in my cell phone, but what if I could find a way to run wires from the outside of my phone to the battery on the inside, augmenting that battery? The problem I have is that I'm not sure if this will result in extended battery life, or an explosion.  I know that Li-Ion batteries are not like your normal AAs. And I know that to keep the voltage right, I'd have to wire them in parallel.  But if I wire them in parallel, without some sort of circuit in front of both batteries, will that be safe? I think that if there was a circuit in front of the two batteries hooked up in parallel things would be fine.  But if I just hook to separate batteries in parallel, each meant for my cell phone, then each battery will have the circuit protecting it, but not the two in parallel, and that might be dangerous. So anyway, if anyone out there has any idea on how safe this is or isn't, I'd appreciate their input! Rick

Kid has destroyed earjack on cellphone. I removed the jack but it still puts audio to the imaginary jack.

I guess he put in a full sized ear jack and it takes mini so it is obliterated. I got rid of the physical jack and all its parts but it still outputs audio to the dead jack apart from the "turn the fone on"  sounds. So, am I missing something? Is there some secret thing that is stuck in the on position? Anyway, probably lots of kids have broken earjacks so maybe someone has the same problem and knows a fix? It is pay go  out of waranty (just 14 days)  and it still has 50 bux on it.

why are cellphone chargers so small?

I was thinking what kind of transformer are in those cellphone chargers. their output are so high considering their very small size. is it possible to use audio transformers to step down mains AC? if yes, is it safe? my professor gave us a very simple project - to make a power supply. of course i will use a transformer. when i pass my project she told me that i used a audio transformer. i don't know that the transformer was an audio transformer because it was labeled 220v 50Hz to 9v 200mA i searched my area for transformers i found several with identical ratings but they are significantly larger. my conclusion is my transformer was small due to the fact that it is an audio transformer. when i searched for audio transformer i found a lot of very small transformer. now, is it safe to use those very small transformers to step down 220VAC mains?

I want this cellphone thing, please construct?

This is my dilemma and I am sure I am far from alone.  I work for an employer that does not allow me to bring my cellphone into the building because of data sensitivity issues.  because our cellphones all have nice cameras in them now, it's a no-no. I am a parent who would still like to be notified of an emergency.  What I want is a small device, I'm picturing a little disc or square that can fit in my pocket and vibrate if I receive a call from 3 to 5 specific numbers.  For example if the school calls, or if he calls from his cellphone.  I can know I need to run out on my break or find a way to call from inside the building and call him or the school back.  Kind of like a call notifier for emergencies.  Maybe similar to Life Alert. I am not into electronics and have no idea how I might equip a device and make it communicate with my cellphone through possibly an app or something.  I just want this.  If this happens to be some new idea and you'd like to develop it as a company, I'd appreciate some notification, credit and cut of the profits or purchase of the intellectual property.  You'd really be doing a working mother a favor.  Otherwise create this thing and sell me one.  I will definately buy one and sell some more for ya.
