Agreed. Major props for innovation and thinking outside the box. Hope you get the stability issue figured out.
i thought maybe adding a thick rubber sheet or mouse pad and THEN velcro or some other thing between the two project boxes would work. of course i’ll need rubber feet, as well.
M1x4h:
how would a screwable extension cable work?
i’ve thought about the interchangeable parts issue. it turns out that it may need a third box for the PCB, since the stick and buttons should be swappable. either that or there should be a big case that can fit both the buttons and the stick. not portable, but useful. 
i can’t imagine trying to put art on something like that though. the art would have to be around the swappable parts only.
well… You’d have to make it like a serial port on a comupter, where you can screw it in. this way, it wont fall out. that’s the only concern i’d have… and serious carpel tunnel from not having a rest for the button hand.
it doesn’t ever fall out in the current state it’s in. it just… moves around a lot. the DB15 is pretty hard to remove by accident.
Quick question for leaveal (or anyone who has used OBSF-24 buttons):
I noticed that you used OBSF-24 buttons instead of the regular OBSF-30. Did you have any difficulty getting used to the smaller buttons? How did they compare to the OBSF-30 ones? Any miss-hits?
Thanks in advance
not really – if you space them properly, you’ll barely even notice.
you just have to know which part of the 30mm button you actually press, and then estimate the position using 24mm buttons. it’s not that hard, and it pretty much feels the exact same as a bigger Sanwa (ie still good and sensitive.)
