> It looks like the panel is setup for the Ext I/O connector I chose which was a mini-Din. There isn't a lot of retention force to keep the plug inserted into the jack. There are threads on that jack so there must be a plug somewhere that will connect and screw in. I've been unable to find one. It works but could be better.


Assuming a threadded plug cant be found, may it be a good idea to swap the connector to somthing else - possibly even another D port?

This'ld be good for me, as milling the recessed plug, as specified in your .fpd file was tedious.


> At the time I did my panel I chose Piher potentiometers because there were 16 on the panel and they were relatively inexpensive. They work fine but note if you use some other potentiometer the hole diameter is probably wrong. They use a 7 mm hole. Also note each shaft has to be cut off which is easy since they are plastic. I used RadioShack 274-415 since they were much less than the Tyco knobs.


Changing the hole dia is no problem (if anyone else needs panels)

> I ended up masking and painting the edge around the LCD. It sure would be nice if someone could find a bezel that would work.

There is stuff used for engraving to colour very fine cuts black.
It works by oxidising and colouring freshly cut surfaces, so you can apply it to a natrural anodised panel, and itll only blacken the broken surface.

Anyhow, ive been considering getting some of this, but holding back, as its nasty carcenogenic stuff. If i do throw caution to the wind, it may be usefull for that kind of work.


> The biggest issue in building this panel is there is no PCB for the 11 LEDs. This is just waiting for someone to join in and lay one out and figure out a mounting scheme.

Even a pcb without mounting would help. The simple friction across 11 leds may be enough - but then again, this may be negated by the extra weight of the board hanging off the back?

I normally hate using adhesives as theyre generally no good, and, from a service perspective, are a very bad idea, however this may be an area where they are usefull?

Or possibly, two of the LCD mounting screws could be used on one side, and two more added on the other, to hold a LED pcb?


My machine can do pcbs also. Its no good for big runs, but for small quantities of simple boards, it may be worth considering.
