Best Smartphone to not use as a smartphone?

I would like to buy a smartphone but a don't want it for calling or texting. I just want to use it for listening to recordings and music and watching downloaded videos and I would like to take pictures with it it and do all the other things a smartphone can do except what it's designed for. What phone would you recommend? I want a phone that has lot of accessories made for it. I would like this phone to be under 150$. I want to also use this phone for lots of DIY projects.

Is it possible to use a Samsung Star (GT-S5230) without a SIM card for instructables around here?

Recently, a family member was trowing a non-functional Samsung Star away, but I kept it. There were two things broken: the side-buttons, that aren't really that necessary; and the touchscreen, which, even though it's pretty much indispensable, can easily be replaced for around 15$. Now, my question is, is it worth replacing it? I have searched quite a lot, but most instructables involving smartphones I find end up mentioning Android, and Android apps (specially arduino instructables), and so I'm not particularly sure this phone would be good for that. I don't want to use it as my phone, so the smartphone cases/holders/stands instructables aren't (by themselves) useful, in this situation. That being said, if you know of any (good?) instructables either about or using smartphones that could be done with a Samsung Star, please link me to them, I will be very thankful.

External smartphone Monitor using old laptop LCD display.

  Hi there, I am currently working on a project on reverse engineering. I wish to attempt at somehow using an old laptop lcd, as an external display for my smartphone. As an amateur electrician and computer programmer I would love it if someone could direct me and tell me which goals I have to accomplish to make that happen. I understand that the signals coming out of an lcd display are different then on a cell phone so I had found a control board that will transpose the signal into a VGA signal which can then be directed to a computer. But is there a way to send the signal to a usb port for a smartphone to plug into. Granted a program, software and drivers for the monitor ets would need to be created but that aside, could something like that be possible? Please indulge me. Thanks for your time.

Help needed making a pause system for smartphone headphones

Hi guys, I'd like to take an existing pair of headphones (not a specific pair, I can buy a suitable pair if this will make things easier) and implement a switch that will automatically pause my android music when a switch is pressed. Specifically, I'd like the music to pause when a circuit is broken. Since Android will automatically pause music when the headphone jack is removed I can't imagine this would be too difficult to build. However I would also like the music to automatically start again when the circuit is closed again. I'm not overly tech savvy but I think this project is within the realm of my capabilities! Any thoughts or help would be much appreciated! Regards, Tig

Portable Speaker from Android Smartphone

I have been reading a lot of DIY articles on how to build portable bluetooth speakers, and I'd like to take it a step further. I have at my disposal an old Samsung Droid Charge, a pair of Logitech computer speakers (powered), and some pioneer bookshelf speakers. What I would like to do is somehow use the electronics in the phone to provide all the necessary connections. Since the phone has bluetooth, a rechargeable battery, and an audio jack/speakers, I would think this is just a small matter of soldering and fitting everything into a cabinet. The problem is that I'm not an electrical engineer, so I'm probably overlooking something. If you have any ideas, or know if something like this has been done before, please let me know! EDIT: I've simplified my project, and I no longer need help with this, but if you do know something that would help, I'd still want to give it a shot.

Old Smartphone LCD as Head Mounted Display?

I've got an old HTC EVO 4G, otherwise known as the PC36100.  I'm attempting to create a 1 to 1 display to connect directly to my computer for a cheap Head Mounted Disply.  I've attempted to use various wireless RDPs.  However, the lag while attempting to do ANYTHING is horrible.  So I attempted to find an app that would connect directly to the phone via USB.  I found two.  Neither of which I feel comfortable dropping money on with such poor reviews and trials that don't work. So finally, I decided why not just use the LCD directly.  No messing with the hardware limitations of the phone at all.  So I took the phone apart.  I got right down to the LCD itself and found that it has a 17-pin input.  But, I don't really know much about it beyond that.  I can tell you that the cable reads: Career 06 94V-0 <->2 C36_FPC REV A I even have a picture of it.  I think it's attached.  If not, I'll fix that. Essentially what I want to know is, what do I need to make it be a fully working LCD monitor for my computer.  I know I'll need a module to convert the signal from what it is now to HDMI or VGA whatever the case may be.  I also know I need power to the screen.  But, beyond that, I don't know where to look.  I've tried looking up the cable information, but I'm not getting great results.  Any help in the matter, would be greatly appreciated.  Thank you.

My full Idea (Don't know if feasable) is to use the turn by turn information of a smatphone navigator that uses GPS (like the one of google maps) to activate one of two vibromotors, there would be one vibromotor on the right arm and the other on the left, if a next turn is needed to be made (info from the navigator) a signal will be send to the the motor on the left arm, It will vibrate and let the user know that this next turn needs to be done. I need urgent help since I don't know which components I may need and how to develop the software or anything I will appreciate any hint.

What kind of lens could I use to fix the broken one in a smartphone?

I have a bad smartphone, so I decided to build a night vision device out of it. I broke the IR filter inside the camera module, but somehow it looks like the camera lost all the focusing ability with the removal (or damage to lens) of the filter. It works almost perfectly on really close range (like macros 1-2 cm), but in other cases, like a room, or the street it is blury as hell.

How to answer my land phone from my Android smartphone using Bluetooth or Ethernet? Answered

Hello, guys! For academic purposes, I want to develop a solution so that I can answer my land phone directly from my smartphone when I'm at home close to the land phone, so, no Internet or other kind of long-distance communication here. Imagine a scenario where I'm at home, the land phone rings and I have the call information on my smarphone and I'm able to answer or reject it directly from my smartphone. I know the phone carriers offer services called "Follow me" that will redirect the call to my cell phone if it rings a few times and no one answers it, but, that's not what I mean. I want to answer the call on my smartphone as if it were an extension of the land phone. Two ideas came up to my mind, but I'm not sure I could make any of them work. 1- I thought of using some microcontroller like Arduino or something to hack the phone and somehow work as a bridge between the land phone and my smartphone via an Android application using bluetooth or a Wi-Fi ethernet connection. 2- I also thought of using a cordless phone base and capture the RF signals with my Arduino and make it route the call to my smartphone, so that it would ring when the land phone receives a call. If you guys think none of my thoughts would be viable, I would accept any kind of suggestions, even the most weird ones involving interconnection between multiple and heterogeneous devices, hardwares, softwares, technologies, etc. Thanks in advance!

Nokia Lumia 520 without plan

Hi guys. I have been thinking about making/getting a portable game system, and have come to the conclusion that the easiest and most portable way to do this is to buy a cheap smartphone (either android or windows phone 8.1 but not ios because I don't like apple (except for their ipod series, that idea was revolutionary)) and put only emulators and games on it, maybe even steam or origin or desura, pretty much any good game client. Pretty much just use it as a device to play games on. But, I don't want to pay for a smartphone plan. I have read that you can somehow use an android phone as an ipod, but how this is done I have yet to find...I know that you can unlock and root but you still need a carrier for the phone to work. So my question is do any of you guys and gals have any idea of how to go about using a phone without a carrier, as a game system (which means I really only need data)???????I have searched the internet high and low and cant seem to find an answer. And btw, the phone I want to use is the Nokia Lumia 520 (running windows phone cyan update).
