Just wanted to share my latest project. A mobile cart set up to do Raspberry Pi programming, DCC encoder programming, and to run my small switching, HO railroad. Can now do much of my work in our family room with the wife or wheel into the train room. $57 for the cart and "shelves".
Update, found that the screen monitor I used was insanely small. Replaced it with a 24" HDMI TV (and it only cost $88). Much easier on these old eyes!
On Amazon, Altra Furniture, Ameriwood Home Sheldon Mobile Computer Desk, Black, was $35.91 delivered when I bought it in October, now $46.34. Got the shelves (which are actually plastic, stackable bins) at The Container Store on special at about $10 each. Just shopped around.
