My thought process is that given the battery life of the typical phone, I'd think you'd rather leave it plugged in all the time (hence the extra cable that's basically necessary to have). Especially when the original poster was thinking about making use of older phones past their useful life, and (presumably, given the age) with batteries that no longer keep a charge for very long.
_Maxxx_ wrote: Sorry for the sarcasm but I felt your post was unnecessarily negative for someone asking for our help!
Not at all. I'd rather give a newcomer something to think about upfront, rather than have him go through the effort, only to realize that in the end, it's really only going to be marginally useful. Been there, done that, spent hours coding, and then finding out I'm only going to use the program once or twice.
But then again, maybe his project is about learning how to do it, and not strictly about getting it finalized. In that case, more power to him.

I grew up with keyboards without num-pad on the right side, so for me it is useless (as I do not use the existing num-pad)...

I believe you may have reversed the exchange rate.
But it doesn't really change your point.

I did indeed...
My fault, I bought something on FleaBay and it arrived today - a heck of a lot more than I thought I was buying and that confused my sense of money.

Ok,
This is me talking. Answer: not very easy.
And if you and I were to team up, I'd need to throw a lot of philospophy at you. Stuff like, "you be on the opposite team" or "I pick (the other guy), someone has to sit out".
And I'd have to ask this one question. And get ann actual answer. Is it all right with you guys if I remain on skins because I'm really buff?

I was actually looking for something like this a few months ago. This is not something that I would put on my pc, but I could use my phone as a mouse for my tablet.
I have a Lenovo Win 8 tablet and was looking for a keyboard, most didn't have the mouse or trackpad. Sometimes my finger just isn't small enough, and I haven't been able to find a finger sharpener. Since I always have my phone with me I figured I could use it as the mouse for the tablet.
As it turns out I got a Lenovo keyboard with track button(?) so I don't need it.
So while I wouldn't use it on a pc, I certainly can see using it with a tablet.
Jack of all trades, master of none, though often times better than master of one.

That's actually not a bad idea: the phone has inertial sensors, and you could use the screen as buttons, then connect via bluetooth.
If you can do gesture recognition with your phone, then you could use it as a mouse.

It is already out-there - go and Google for it...

How long is a piece of string? It's not that difficult if you can write Android apps well and can write PC (or Mac) applications to handle sending keystrokes to the OS
If you can't do that then it's hard!
Member 11392066 wrote: So, basically take the old phone and use the micro USB to plug in
I'd be more adventurous and look at using WiFi or BlueTooth
Member 11392066 wrote: does that already exist?
There are apps that do something similar - but that doesn't stop you writing a different / better one!
There is one for the iPhone, for example, that allows you to use the accelerometer in your phone - so you can run an app on the Mac and access the accelerometer data - very useful when developing phone apps!

Having a goal is the best way to learn software development! It gives you direction for your learning.
Why not try. Start off with writing an Android app with a button and working out how you can detect that button being pressed on a PC (connected by USB or wi-fi or Bluetooth - or all three!)
Then work out how to make the PC app send a key to the OS when it detects that press.
For a simple numeric keypad, the rest is just coding!
But you could see if you could add mouse emulation, accelerometer info - and anything else you can think of.
Breaking it up into simple steps (make it look pretty last!) you can then ask specific questions of people when you get stuck & can't find an answer out there.
A quick search found me this[^] link which may help you get started.
Good luck!
And when you get it done, write an article here on how you did it!

Hi everyone. It's me in my old clothes. They feel nice. Just thought I'd formally say hi now. 
There have been joys too great to be described in words, and there have been griefs upon which I have not dared to dwell, and with these in mind I say, climb if you will, but remember that courage and strength are naught without prudence, and that a momentary negligence may destroy the happiness of a lifetime. Do nothing in haste, look well to each step, and from the beginning think what may be the end. - Edward Whymper
Climb On!
