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

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.

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

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.

I really like how Flip Video Cameras have built in usb connectors, and i really want to try to integrate something similar into my phone which has a micro usb port so i can charge it and drop off files whenever i'm around a computer.

Cell phone dock

Check it out: I'm a major Android fan. Sure, Mac makes some incredible machines, but I just hate how shut off they are. That's why I love Android. You're able to change the battery if you, you can expand your memory, you can even make your own apps without hoping to gain someone's permission.  However, the one thing that iPhones have over Android phones is the fact that they have the ability to be placed on a dock. My question is, why can't Android phones do this? Now, instead of making docks for these phones, maybe it's possible to use the ones for iPhones that are already there. What if there was a little plastic piece that snaps on to the iPhone dock and has a mini or micro USB male end on the other side? Of course, there are all kinds of sizes and shapes to Android phones, but I'm sure once this piece is perfected, one could make different shaped ones for different phones to fit neatly. Most of you are much smarter than me (or maybe have more ambition), so I'm sure you can figure out how to do this sooner than I can. If you have and idea on how to make this work, good luck and let me know how it turns out. P.S. If you make this and market it, be sure to credit me for the idea, yeah? ;)
