Hey people....ive just recently finished my TPD (track position display)

And now i want to build the Button Led Matrix.

 

Ive seen there is a gerber file online for the BLM and i want to see if there is other people interested

in a pcb (or pcb+partskit) for the BLM (4x16).

 

(i prefer to do small batches (max 10 or 12)...so be quick) !

I'm assuming you're making Ilmenator's 4x16 pcb?  I'd be interested in a PCB that fits standard tact switches, but I think those marquardt switches would make it a bit too expensive for me.  They're definitely pretty switches though.

you're going to need to buffer that serial line if you plan on running a cable anything longer than a few inches

 

On my build, the cable running from the SEQv4 control surface to the BLM16x4 board is around 25cm long, the one going from the BLM16x4 board further on to the TPD board is around 50cm. No problem here so far.

well, when I have the PCB I will test it ...

spacing between the two poles is 5.08 mm like the marquardt have ..
problem is that one has to cut the second pole pair of the ITTshadow ... 
and that the poles are not centered like the marquardt 
so the pushbuttons will be slightly de-centered ..

bevore christmas would be better i think - holiday time is soldering time...

 

first thougt - it would be easier to change the pcb - is there a link to the files?

Well ... easier for electrodancer would be if I simply use a drilled solderingboard for those Switches :D

cool would be to have one PCB that has both connection possibilities ... 

 

The Gerberfiles are here http://www.midibox.org/dokuwiki/doku.php?id=16x4blm_pcb
