A case for the Red Pitaya scope/function generator

A case for the RedPitaya

A shielded case for the scope/function generator instrument from http://redpitaya.com/. The bare RedPitaya is just the board and without any shielding or protective housing - this project attempts to remedy that. This is on Thingiverse.

The shield-metal-cut.ps PostScript file is the source for the shielding. Print this on paper, glue on a thin (best tinned) iron shield metal and cut out. Make sure that your printer program output is scaled 1:1. The PostScript program is hand-written, so easy to modify (essentially poor-mans parametric 2D CAD :) ). If you notice that your printer does not scale the output properly (there is a line of reference length in the printout), you can correct that directly in the program, just change the actual length in the /measured-reference-length variable. If you need a DXF file, create shield-metal-cut.dxf with the Makefile.

(If you have a laser cutter or other means to automatically cut the shield, please let me know what the best way is to provide a file that separates the mechanical parts from the documentation text. Different color ?)

The OpenScad file plastic-case.scad is the source for the 3D objects. These are the stand-offs and the actual case. (The plastic-case.stl file is the binary result included in this distribution for easy use). This is the first shot; if you have improvements, just send me a pull-request.

The top part of the case will just be attached with the 'melting plastic on hole' technique found in many consumer devices (anyone knows how this joining technique is called ?)

The final case looks like this; the arrows show input/outputs.
