for electronics enthusiasts and instrument builders, we've decided to
sell some of our logic boards alone.

fully assembled and tested, with choice of firmware (analog or
encoders).

since the firmware is reprogrammable, this is really a nice kit for
experimentation. onboard are USB, maxim 8x8 led driver, 8bit shift in,
8bit shift out, and 4 open pins with pads (also 4 ground and 4 V+ pads)
for easy soldering).

we highly recommend some electronics experience for this circuit to be
useful to you. silicone keypads, led board, leds, enclosure, top plate
(all of the *really* expensive stuff) not included. we'll be here to
help you out, and look forward to seeing some custom designs.

$80, very limited stock. contact us via email at orders@monome.org


cheers!

Hi huys,

This is great! I want to buy 4 of these (2 analog and 2 as encoder)
to include in my next project and to add to the development of "leaving 
Traces"

please let me know how 2 proceed.

I'm a dutch interactive artist and follow your works for some time now.

great! e-mail orders@monome.org and we'll get to it right away.

Is there a resource that explains how the buttons and leds and such are 
hooked up to the logic board and also how the firmware works with the 
shift registers to interpret button presses and whatnot?  I'm totally 
new to the monome and I am trying to figure out how hard it would be to 
take one of the logic boards and build up a monome out of my own 
buttons/leds/enclosure.

Thanks!

i'm actually working on these walkthroughs/graphics right now. i'll have 
them posted very soon. it wouldn't be hard to make your own, but will 
take lots of time wiring/soldering, and acquiring the 
buttons/leds/diodes won't be cheap if you use really nice buttons.

first revision up:

http://wiki.monome.org/view/40hLogicBoardCustomProjects

This is great because I can't afford a full-blown 40h (unless someone 
wants to offload theirs, maybe?) but I've got time to make a homebrew 
one (but everyone knows it won't be half as cool-looking, oh well). I'm 
just curious, are there enough that if I ask for it for christmas and 
don't get it, there'll be one in stock for me to buy?

yeah, we'll probably have enough.

i think i'll probably be getting a logic board seeing as how i can't 
afford a 40h in its full glory either. how many are still left?

sorry if this is obvious, but i wasn't quite clear on what the 
difference between the two firmwares is. i found where it said that the 
adc firmware comes installed on the 40h, but do they just change the 
available format for mods?
i guess what i'm really asking is if i'm just planning to (for now) make 
a button/led grid for the logic board, does it matter which firmware i 
get?

we have some left, in not sure how many.

the firmware options (adc/enc) change the behavior of the 4 aux inputs. 
either four adc (knobs, accel) or two encoders. check out the tutorials 
on the wiki to get an idea.

nope. the firmware is rewritable also, if you get yourself a programmer 
($50) and go through the (slightly intense) devtool install.
