How Can You Convert a Cellphone into a Tablet?

AI Thread Summary
Converting an old cellphone into a tablet involves significant challenges, particularly in finding a compatible larger display and dealing with the limitations of the phone's existing hardware. The original pixel density would decrease with a larger screen, leading to poorer image quality, as the pixel count is fixed by the device's video drivers. Developing custom software could enhance functionality, but older phones typically lack the processing power to support advanced applications. Alternative uses for old Android phones include repurposing them as security cameras or other useful devices, leveraging the open-source nature of the Android OS. Overall, while the project is intriguing, practical limitations may hinder successful conversion.

Hello everyone, I'm sort of bummed that no one seems to be doing anything with their old cell phones, so I thought swapping a 4in LCD screen on a cellphone with a 10-12in one off the internet would be a unique project that I could document for other interested people. The problem is that I lack the necessary EE knowledge and experience to do it on my own. I was hoping an EE on here would find such a project interesting, and sort of guide me along the project. I figure my old Samsung Droid Charge (i510) would make a good donor cellphone.

Swapping out for a bigger display (Assuming you could find a compatible one) would only give you bigger pixels. Kind of like digital zoom on a camera. The bigger it gets, the worse it looks. You couldn't increase the number of pixels because that is "baked in" to the video drivers.

You would need to find a display with a compatible interface (same connector pins, etc).

Unless you are willing to develop custom software for the phone (possible for android). But even that would be a waste since the older phones have less powerful processors.

There are projects to turn old android phones into security cameras, etc.

And lots of other ideas.

Android phones can be usefull computers since the the OS is open source and they are easily messed with. I can't say how easily since I have not actually programmed one yet.
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
