Update: 9/25/2010 to http://openpcr.org/2010/07/treat-your-machine-shop-professionally/ Good comment from mo - spread the love around. I want to point out that the relationship with your machine/PCB/acrylic/wood shop can be challenging! It's important but not necessarily easy! If you can't meet in person it's tougher to build repertoire over email or telephone, no matter how charismatic you are.

(I'll read up on what size nodes to use with acrylic, or comments are appreciated!) This was my first...

This week I designed and sent off requests for new laser cut cases -- one wood sheet from Ponoko, and an acrylic sheet from Pololu. Material: One surprise for me -- I made a slightly bigger case, and adding on 1" to each dimension roughly doubles the material. For instance, take a 4" square, that's 16 square inches of material. A 5" square is 25 inches of material. This can get out of hand pretty quickly! Speed: On the recommendation of a friend, I browsed onto Pololu.com, which offers custom laser cutting services. Pololu doesn't have plywood or bamboo in stock, but they do have 1/4" acrylic...
