Does anyone know if something similar to pic related exists?

You could probably make your own for pretty cheap if you can solder.

Would an xbox controller work? I think I've also heard of apps that you can put on your phone to use as a bluetooth controller for a computer too

make your own. teensy 3.2, perfboard, your switches of choice, and soldering equipment.

I've never done anything like that before but it sounds like a fun project. Thanks /g/. Back to /o/ for me

Just get a USB numpad

Or just buy a usb numpad or something

Dude just download unified remote for android.

>Even a small flat USB mouse with left/right click would work

I think this is the best idea. You can get one for $4 on ebay with free shipping

I'm not sure what the problem is. Does it have to be 4-key? Is a number pad really that big?

Why you'd want one in the first place is a good question, though. I use a (pc) remote for my HTPC. I'm fairly sure that's a better solution.

I just use vidayi game controllers for media control
used to use and xbox360 one with xpadder, use a steam controller nowadays which is really nice to control the mouse with so I can browse from bed as well

I prefer using a controller than my phone for something like this

>>60906088
fair enough, but now you know another thing in case you need it

>>60905445
Just checked, it seems to be 45$ now.

You can remap some useless keys on the keyboard like inser, sroll lock and pause break

>>60907946
but they're not useless
I think he wants something more portable anyway

>>60904856
Go on etsy and search for "osu 4k", you can remap the keys.

Are there any chinese ripoffs out there worth looking at?

>>60904856
Dude you can buy a Teensy 3.2 microcontroller for like 20 bucks. Then you can program it to insert keystrokes from a button push or pretty much any sensor compatible with the microcontroller.

>>60904856
Buy a chink numpad, a Pro Micro, diodes, and a soldering station eventually
Connect the columns with simple wire and the rows with diodes, everything on the PCB; if you have time to waste you can remove the PCB and use only the housing, but the PCB makes the whole thing sturdier
Connect the ends of each to the Pro Micro
Detach the USB cable to the pad's PCB and solder it on the Pro Micro
Download TMK Firmware
Configure a layout (it's pretty easy, it's C preprocessor)
Compile and flash
Done

Obviously I meant a numpad with mechanical switches

Here you go faget.

I've done them all and they all work fine, esp if all you need is 2-4 keys and know autohotkey.

>useless

Why do I feel like I have been baited?

>>60909362
Most people will never touch insert. Almost all people never touch scroll lock or pause break.

>>60905445
Huh, I didn't know something like that existed. I wanted something like this to control volume, mute on press, and second knob to switch audio tracks and pause music so I made it myself from arduino and 2 encoders. Didn't cost me $35 too.

>>60904856
Could you use a cheap gamepad?

>>60904856

Why don't you use one of those arcade boards? Learn a bit of soldering.
