07:46 <lekernel> i'll probably reuse most of it as a first step

09:17 <roh> lekernel: nice concept

09:17 <roh> so its 2x hdmi sdtv input and one vga output for the prototype?

09:19 <roh> lekernel: i thought about your case request, and i think i could design one, but i dont have the tools to manufacture it. but i am actively researching companies who have the tools and could manufacture something like that.

09:29 <lekernel> yes

09:39 <lekernel> roh: http://wilkins-knives.com/about

09:41 <roh> nice.

09:41 <roh> i found http://www.jegel-berlin.de/

09:42 <lekernel> there's also a list on http://wilkins-knives.com/contact

09:44 <lekernel> I'm wondering if it's be wise to mount knobs and pots on the main board... I'm worried that mechanical stress can bend the PCB and cause the BGA balls to crack

09:45 <lekernel> on the other hand a two-PCB solution is thicker, harder to assemble, and potentially more expensive

09:46 <roh> i think its not a bad idea to put these on another pcb and mount that to the case

09:46 <roh> when you want a milled case the cost for a pcb is not really any issue

09:47 <roh> or mount the frontpanel knobs on the front itself and use wires and connectors on the main pcb

09:47 <roh> thats what i would do, atleast for smaller series (<100)

09:49 <roh> directly connecting 2 pcb with stacking-conn wouldnt remove the stress to the main pcb but only distribute it. most mixing consoles (atleast the more professional ones) use sepeate pcb, connected by cables

09:49 <lekernel> yeah... but I do not want any visible bolts on the front panel

09:50 <roh> use nice ones

09:51 <roh> sunk hex for example

09:51 <roh> also think about repairability. stuff which is used by people on the road tends to break. thats normal and to be expected

10:06 <roh> also you could make hidden bolts from the backside

10:07 <roh> see the 2nd line, first from the left

10:21 <lekernel> those are for the ticket machines, no?

10:22 <roh> hehe.. could be

10:23 <lekernel> (hidden bolts) nice

10:24 <roh> there seem to be different techniques how to do that. welding these in, or pressing

10:52 <wpwrak> other options: sink the front panel. then you just need grooves in the sides.

10:52 <wpwrak> or bend the front panel to an U shape. then the bolts can go to the side.

10:53 <wpwrak> i think even a fixed stacking provides a lot of relief. a) it adds quite a bit of stuff that can flex and bend, sharing and distributing the load. b) you can choose the safest places for making the mechanical connection (and reinforce them, etc.)
