Modify the work station or need a whole room?I wouldn't.
Ya, you're right, it's a work station not bench. I live in a small apartment, this is in our living room, and this is about all the space that can be afforded.I would start with a sheet of 5/8 or 3/4 plywood about 8 feet long.
You're kidding yourself if you think a proper work bench can be done in 3 feet. That's a work station, not a work bench. With that concept in mind, that you're only going to work one project at a time, quit trying to use your work station as a storage space. Get all the inventory off the work station and put it on shelves. If you keep this up for 10 or 20 years, you will eventually need a whole room.
I'm planning on buying or making some kind of flexible arm to mount to the side and hold a laptop or netbook there so I can swing it in and out.Where do you put the laptop/computer for microcontroller development?
I would add three shelves above the desk, stack the power supply next to the scope and plan for some small boxes below the desk for junk parts - it makes a nice rest to put your feet on!
Just do the best you can in the space you have and deal with it.
I wouldn't change anything. It looks immaculate already, by my standards (low standards, I know).Modify the work station or need a whole room?
So then Don't anchor anything to the wall. Build a tower over the top of the desk, with shelves that butt up against the wall.I forgot to mention, about that wall, that;
1 - behind that wall is the hallway for our apartment building, and it isn't very thick. Thick enough for some screws or anchors, just be careful not to go through the wall.
2 - It's constructed entirely of some form of cement-like plaster that, when drilled, crumbles into dust and when you put an anchor into it, it will pull back out when you put a screw into it.
This apartment sucks.
I might put a shelf there as it's a good idea, but I don't see it being feasible as a place for the scope or power supply because they would be out of reach.
