I've considered doing this myself before, but just didn't get around to it. Considering that ready made products are very expensive, a few hundred quid. I've always wanted to put something like this together, I don't need it to be fancy looking, just needed something to satisfy the nerd in me.

How easy would this be to scale? For example, making it bigger? I know we're talking about elevated costs then, but if buying these panels in bulk, it could be a little fun project for a wall .
