Some news. I received the reply from the Rowmark supplier about their stock. They don`t have the material type we need now, and they said will have it for about a month and will inform me. I`ll get acrylic for sub-panels these days. These days I`m expecting the parts from unit-sound, so I can check its the fitting against the panel I did. If somebody have any spare button cap I would need it for testing. Full set would be even better. :) About the back panel. Back panel cannot be made out of Rowmark material as it have to take much greater stress because if the connectors. It should be made out of 1.5mm metal, so I think it is the best to order it from ladyada store. It cost less than 10EUR. Meanwhile I been playing even more with fonts to see are there some that are cleaner to read. Do you have some proposition regarding the fonts, or you have some good commercial font and you are willing to change it on my file. After checking with magnifier tr909 and Prototype fonts i discovered tr909 is more precise than Prototype. I think it pays to get it best as possible before going to engraving. Kartoshka, are there some results on your side. I got only free fonts to play with.
