@j.e.f.f said in How do I go about making a decent sized mirror cheap?:
@chaseb1357 the cost of your mirror is going to scale proportionally with how big you want to make it. If you want to keep it relatively small (say 20" monitor) then you can likely get away with this:

and combine it with any refurb computer monitor you can find. However you’ll still need to purchase the raspberry pi and build the frame for it. You’ll looking at somewhere in the neighborhood of $250 at a minimum. Not sure if that fits your budget, and that’s before even considering touch capability.
When I built mine my costs quickly spiralled out of control… mine finished around $800. But that was with a 32" TV and a 1.5 meter piece of two-way glass.
They can get VERY expensive… so far I’m about right where you are with the 32"… but like I said I also used a real itx board and IR touch frame… with more to come…
