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.

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?

Why have 'they' not made a cellphone with a learning remote?

How often are you spending more time looking for the TV, DVD, Stereo remote than the time it would actually take to just get up and push the button on the unit? Cordless phones have 'pager' function where you can press a button on the base unit causing the handset to beep. A lost cellphone may be found by ringing it. But very few manufacturers of entertainment system (that i have come across) include a "finding' feature with the units' remote control. WHY NOT? Surely Cellphone manufacturers could "easily?" include a learning remote with the rest of the 'hugely useful' features on them the we use EVERYDAY...like FM radio, biorhythms, international roaming, bottle opener. You see my theory is-- a. that I tend to know exactly where my cellphone is 99% of the time. It is personal. b. The TV, Stereo etc. remote on the other hand are communal. I mean other poeple, like my kids, use them often and thus the remote gets left ANYWHERE. So the two ideas i have put forward is 1. Learning infrared remote in a cellphone and 2. a pager for a remote (new thread pending)
