I'm aiming to make 3 versions of the case.KD9MDL Bill wrote: ↑04 Jan 2022, 14:53
Love the idea of the metal inclosure, my crude toolage and skills should make that an adventure
One someone can do at home with mostly hand tools. Basically print the flat pattern 1:1 on piece of paper, glue stick it onto a piece of metal and cut/drill on the lines. The hardest part will be bending. You can purchase what's known as a "hand seamer" (used in HVAC Duct work) that will bend thin gauges. You can also take a dremel with a cut off wheel and "score" the bend line and bend by hand (I'm avoiding at all costs due to fast spinny bits that can shatter).
2nd version will be a flat pattern (in .dxf format) that you can give to a local metal shop and have them cut you a flat pattern. It will have relief cuts on the bend lines that will allow you to bend it by hand.
3rd version will be a full case with pressed (PEM) fittings and possibly a silk screen overlay. That way if someone decides to bulk fabricate, they'll have everything they need.
I'm not going to tie up this thread anymore, when I get a draft finished, I'll make a new thread for discussion and/or rev changes.
If anyone that is willing to head up a US Buy for the boards/components, I'd put my name in for 2 units. Even though I have the 3d model of the board/parts, I'd like to have an actual unit in my hands before I throw any official plans up.
