Yes, I was looking for something like that - simple and inexpensive.

For lab version we could use 3-LED columns, like the ones we used in UmTRXv1: http://wiki.umtrx.googlecode.com/hg/images/umtrxv1/UmTRX-top.jpg UmTRXv2 has places to colder them instead of SMD LEDs: http://wiki.umtrx.googlecode.com/hg/images/umtrxv2/UmTRXv2.jpg In this case light-pipes are not needed and we could just drill holes at the front panel. I have no preference between U/C, L or slide-in cases. Anything which is easy to handle, inexpensive and looks good is fine. > I found some design tools at protocase, that it looks as though will > pushout 3d cad files as deliverables, but looking thru the project > files -I cant seem to find anything that would give me specifics on > distances between the mounting holes from each other's centerpoints & > how wide these holes are, If someone can point me to a place where I > can find this -Ill take a stab at case design when Ive got some free > time... =) No idea, sorry. I think you'd best contact Protocase with this uestion - I think they should be interested in supporting potential customers. > On a side note, They also have an extruded aluminum offering > (http://www.protocase.com/products/index.php?e=Aluminum) where the > sides are the same between the left & the right, with a fixed height > of 1.72" (43.688mm).

Hum, this looks interesting. Though we need something ready, i.e. already cut and with ready-to-use front/back panels. I wonder how much would it cost to get cases shipped from them to Europe. For, say, 20-50pcs. -- Regards, Alexander Chemeris. CEO, Fairwaves LLC / ООО УмРадио http://fairwaves.ru
