I know how to drive a DisplayLink monitor from an android device, but I was wondering if there was a way to set up a burner tablet to be a USB monitor. So you would connect it to a PC and the PC would say something like "Oh look. A Zenscreen"
MB169B+｜Monitors｜ASUS USA
ZenScreen portable monitors are designed to boost productivity and enable entertainment while on the go. Compact and versatile, they’re easy to set up anywhere and can be used in various scenarios.

and the tablet would then behave as a second monitor?

Hi there
I'm embarking on an ambitious project and i was wondering if anyone could help me by giving suggestions.
I am making my own home automation system, and I already have the necessary hardware to get it up and running, but I want to take it a step farther.
I have this (Use google translate lol) http://cba.sakura.ne.jp/kit01/kit_399.htm kit, which is basically a set of 8 relay switches that can be used to turn on and off mains devices (such as lights, powerpoints, ect) that are controlled by a computer through a DB25 printer port. I also have an old Dell D600 laptop that has said printer port, and the software needed to drive the circuit board. This is all well and good, as everything is working so far, but before I bother to install this thing in my roof and hook it up to control my lights, power points, ect, I was wondering if there is a way to use my android phone (HTC Legend, unrooted ) or tablet (Motorola xoom wifi rooted with Tiamat, o/c to 1.7ghz) to control this board through a computer.
I already have a client that remote controls the computer (splashtop remote), and I can achieve this with some difficulty by remote controlling the computer and using the PC software through my phone/tablet, but I was wondering if there is an android home automation program and its PC client service that supports DB25 printer port pinout settings, so I could directly control the circuit board through the app, like the leading home automation apps already available (minus the extremely expensive proprietary hardware that you need with them). If not, has anyone else considered developing one? If anyone could give me any help on this it would be greatly appreciated.
I want to design a program that will run on an Android Mini PC. It'll be connected to any monitor so that when the monitor is turned on, it'll power up the android mini pc via USB (monitor will be required to have USB port) and then the program will start automatically and display on the monitor.
The program itself is a visual acuity chart (like at your eye doctor's office). So it will run all day as you use an RF remote to flip through the images.
Sound easy? I'm trying to figure out if Android or Raspberry Pi would be best for this.
Thanks
Pretty cool idea. The only thing I can think of is Android on the Android sticks allows a customizable boot animation which would be cool to create your own for marketing. The Android sticks are also faster and boot quicker so less wait.
You can also remote desktop into a more powerful machine to offload some work. Essentially have a server as the mainframe.
Android will also require you program it to run at startup. I'm not sure how you do this without a 3rd party app, but I know some apps that load on startup.
Both units are tiny and the android sticks include wifi and there are some Bluetooth models. The Raspberry Pi has neither. And boots slower and isn't powerful.
I think its an easy choice.

ok, so it would at least be possible but I'd need some intricate coding and extra apps which is ok with me. thanks
You need to look at the power requirements of the Android Mini PC as well. Often they draw more power than is available through TV and monitor USB ports. You might get enough power to run the mini PC but if you have wifi, wireless keyboard/mouse, bluetooth and other devices the power draw might exceed the output of the monitor. This is something I am interested in as well as I am trying to resolve the power on/off problem on these mini PCs. The probox has a remote with a power button but I've heard the remote has problems with distances more than 1M.

I won't need BT, wifi, or really anything. I need to find someone that thinks he can tackle this project. Any good places to hire someone for this type of work?

Couldn't you use tasker or locale or something similar to run an app on startup? Just an idea...
So, there are Mini PC available from Ricomagic, that have MHL linkups to home theater PC's, and allow for an easy Android Display.

Could these devices be stuffed into Phone and Tablet Form Factors so it's effectively one device that you can run Android on, mix and match your brains with your outside form, and have a universal device of sorts?
I teach 4 math classes of struggling students that like to goof around alot. The new fun thing to do instead of paying attention is messing with the projector during class using apps like WatchOn and Peel. Are there any ways to prevent these apps from syncing with my Epson projector?
Hi,
I understand your predicament. The infra-red is not encrypted and is works on easily available open-source codes. Programmable remote controllers (Combination TV, DVD, hi-fi, etc) are also very cheap and easily available these days.
I think the only way to resolve is to use hardwired remote controller, ie, using a USB cable. There are different approaches for short-distance (up to 5 meters) and long-distance.
Typically, a USB mouse is limited to a 5 meter cable maximum. There are readily-available USB extensions cable to control the projector or PC. When you use this, you can prevent remote-control pranks by physically blank off the projector's infra-red sensor by covering it with a piece of cardboard (the user manual will show you where it is). If you are using the older projector with the wireless mouse adapter at the computer, then you can unplug the adapter.

For longer distances, there are other hardware-related solutions to extend the USB range, such solutions usually incorporate ethernet (LAN) technologies so that the USB signal (short distance) is converted to ethernet (long range) and then back to USB.
An example is:

More examples are shown here:

A hardwire solution will eliminate pranksters from using wireless remotes to upset your lessons, but it will somehow limit the presenter's movements..
Hope this helps.
Or you could do what I do and just put a post - it note over the infrared receiver on the projector. This blocks the IR signals from your students phones. I've had the same issue.

I have a cheap cinese tablet (a teclast P80X, see http://www.teclast.com/en/zt/P80X/) that does not directly support screen sharing/casting, wireless display or whatever else is that called.
I'd like to mirror the display to a Samsung smart TV but I'd be okay also to mirror the display to the Windows HTPC that is connected to the TV.
Any reasonably working options? Most of the apps available on the Play Store are just wrappers around the built-in wireless display support that is not available on this tablet. TIA.

There are mobile app/PC program combinations that work together to share the screen to your PC if they are both on the same wireless network. If you have a PC or a laptop, you can use these app/program combinations to share the tablets screen to the PC or laptop then connect the PC or laptop to the smart tv via the PC input port on the tv and the PC or laptop's screen will be displayed on the TV.
It's a bit of a roundabout, but, given that your hardware does not support screen sharing, you will not find a software solution to achieve this, you will have to use some kind of external hardware.
If you can find an app on the tv that has a companion app for your tablet that work together in the same manner as the mobile app/PC program combinations.
A Google search for
"Share android screen to PC over Wifi"
Should find many android/PC screen sharing solutions. Find one that works and that you are comfortable with, use it to share your tablet display to PC/laptop then connect the PC/laptop to the TV. I do this myself when the need arises, it works for me when needed.
So i ended up using scrcpy (https://github.com/Genymobile/scrcpy) which is just great. The only catch is that you need adb/usb debug which was not a problem in my case.
