If your TV does not have Miracast in it, you would need a Miracast adapter. Note that I have not tested a Miracast adapter, I have only used the Windows 10 function of my computer. I suggest you try it on Windows 10 first prior to purchasing an adapter. Note that I am only listing the ones below because they show good ratings on Amazon. I do not know if they work. Be aware that the plug-in can be glitchy for some people, so definitely test the remote playback plug-in on your Windows 10 machine or your friend’s computer first before you spend money on an adapter.
@Bob_White might be willing to sell you a completed Little Black Box based on a Raspberry Pi. It uses WiFi to take the timelapse pictures. Bob is in the US, so shipping to other countries may be problematic. I don’t know if he’s selling the units or not.
