You can't plan a project like this around eBay junk. How would you assemble 100 kits if each kit requires that you find a specific HP instrument on eBay?
If cost is a big issue then I'll go back to my first idea. Make your PCB about the size os a disk drive. Then yu get a llength od 1 x 1/4 inch aluminum L and bend it into a three sided "U" and attach it to three sides of the PCB. The finished assembly should fit into any enclusre designed to hold SATA disk drives. A PC case could work but there are nicer looking boxes, rack mount and diesktop This trades a bit of metal working for the cost of a Hammond box. But the metal work requires only a hack say and drill. On Tue, Dec 21, 2010 at 8:35 AM, Bob Bownes <[email protected]> wrote: > I do the same with Tek 500/500series instrumentation plugins.
