another hand held dmx tester

Phil:   Personally,   I like the Pacte Enclosure the best........      I would think there is plenty of space for  4 AA's...     I didn't look at all the data to see what is available.

Been looking over the specs for these cases, none of them seem wide enough inside, the average yum-cha 4x20 LCD display comes on a board that is 98mm x 60mm.
Personally i would prefer  to have a display horizontal on a vertical handheld case, thickness might be an issue as well.

I found some cases on ebay that had 4xAA battery compartments but fell about 20mm to narrow.
I'll aim to make the PCB no bigger than the LCD display, it's the RJ45 connectors that may be the biggest hassle for chosing a case.

The easy answer to the RJ45 connector problem would be to lose them and go with a RJ45 wip instead.

one suggestion for the lcd back light hook it directly to the battery pack through a resistor and not through the regulator like i did.  it will get hot quick.

Ok - my case choice at the moment is

Not as sexy as those coloured ones but more practical.

Cutout for the LCD, comes with bezel to hide the extra space, plenty of room for a 4 pack of AA.

Room for various switches etc. Must remember to add a power switch for battery power and external power socket.

Hi Phil,
 
First off, thank you for tackling this project.

In checking availability of that case though, Mouser shows only 2 available, may have to go with this one, it shows 858 available

i think it's very similar, but can't really tell for sure, even with pdf file showing specs.
It doesn't look like it has an open window, may have to modify?

Ta, I did take note of stock, Mouser has 2 each of the black and grey with the cutout and as you found lots of the no cut out (solid) ones
Both cases are identical except for the window.
the SDBK = Solid Display, Black
the CDGY = Cut Display, Grey

The cut out will be simple for most people and with a 2 week factory lead time for the black one it should not really be an issue.

The battery pack is another factor to consider....     two basic styles...   1x4   You are not allowed to view links. Register or Login

  or       2x2   ... You are not allowed to view links. Register or Login

Not the only choices within these styles...    but provides a little more to chew on...  I would think that the 1x4 style would be better suited for the case style being looked.

Spot on the 1x4 is the way to go, it will fit neatly in the case with room to spare for switches etc.

The 3D drawing in the PDF is just brilliant, i can visualise just how it all goes together.

Update:

Here's a PCB based on the Hammond 1592 case, i've keep the majority of components out from under the Display due to the limited clearances for anyone using IC Sockets.

The display module can be mounted to the lid seperate to the main PCB and joined with a short 16 ribbon cabble. I have positioned the 16 way sip connector precisely and will add pcb support holes to the main board in case it turns out that the heights work out correctly, based on the specs. Only issue is the holes in the module i have based this on are outside the main pcb sides.

The board has just been autorouted to get a feel for the layout, if there are a few interested in proceeding with this case then i will spend some time hand routing this out.

The RJ45's are set to the side of the case as there was not room at the top due to module, They work at the side imho.

I haven't yet worked a full BOM out - tomorrow......

Cool

Thanks for doing this Phil

Phil/Rob & company,

I am interested in whatever you all come up with. Looks great!

I looks good.  Where would the scope hookups be located?

I looks good.  Where would the scope hookups be located?

All the IO (except the rj45s) is available from headers, individuals can choose a desired external connector, plenty of space, three RCA sockets maybe.

Same for the XLR connection - three pin header.


Plus: looks like i can buy the case in Aus at only a slight premium so i get some bits ordered tomorrow so i can test fit based on some print outs.

Cheers
Phil
