One of the projects I really wanted to get back to when I joined the Austin TechShop was my Reflow Oven based on a Toaster Oven.  The first prototype I made was a mess of AC wiring boxes with an Arduino sitting on the side.  While the oven did work, it was far from pretty.  Making use of the laser cutter, large workspaces, and friendly members at TS Austin, I was finally able to put together my 2nd prototype.
