MOTM

Well, my little MOTM is growing, and I am not yet ready to build a 
Case-o-Doom to house it.  My system is still sitting in a 12 space 19" 
rack.  The part that has been a bummer is that 3 unit wide power 
supply. I know many of your have mounted your power supplies in other 
ways.  My rack was scrounged from what I had on hand, and the only 
thing available was an open back 12 space effects rack.

After some thinking, I decided to use one of the 2 empty rack spaces 
at the bottom for my power supply, and the other for a Lexicon Vortex 
that is currently a guardian of the dust in my closet.

It turns out that you buy a blank 1u panel cheaply, and with a small 
amout of work get everything mounted nicely.  There was space left 
over for several jacks, which I use for the input, output and control 
signals for the Vortex.  It is much more handy to have them on the 
front panel where they can be easily patched into the rest of the 
modular.

Just some thoughts and encouragement to experiment.

Paul and I briefly discussed re-doing the power supply to a 2U panel that
could be mounted sideways.  You of course, can mount two 2U MOTM modules
sideways on standard rack rails in that bottom 2U of space.   I don't use
the pop up case, but I think it would be cool to have some stuff
specifically made for those bottom rows.  Maybe case 1 could have one side
the power supply and the other side a multiple panel with a DC connecting
jack to go to SKB rack # 2.

SKB rack # 2 might have a 2U with multiple and power jack (the receiving
end) and maybe Paul's 2U mixer on the other side.  Of course, it would be
cool to have a panel with the graphics sideways for such an application.

hello all,

of course you do realise that the Vortex is voltage controllable, i'll dig
out the details and post them to the list tonight

menawhile, i'm proud to announce that i love the forthcoming Oakley OMS-410
(the companion module to the MOTM410), i've had a PCB on test most of the
weekend, and couldn't really get away from making random percussion hits,
80's style, using the MOTM100, Encore UEG, and Oakley Noise/Filter to
control the vactrols on the MOTM410 to modulate some MOTM100 white noise...
...Paul, Tony & Tony would be proud, of course, using the random voltage /
infrared noise combo on the 410 is also great for picking out the hamronics
of a generic synth pad without the predictability of an LFO

and i also found time to finish off a pile of DIY modules - aren't public
holidays great..?

cheers

can you post some details on how you did the power bit? my poor soldering
iron is feeling neglected and my pop-up case is full. i'd like to cram a
few more modules in it until i embark upon the "case of doom" odyssey
myself...

thanks!

bleep.
out.

A pertinent thread!  I too will soon be in need of more power than the std
.8A supply can provide.  I agree that using the 2U of space some of us have
at the bottom of our cases/racks for the power supply is a great idea.  It
would also be a good location for the 940 patch panel or DIY-Expressionist
breakout panel.

I have some additional ideas for those of us who will soon be needing more
power and that also would reduce front panel requirements:

Two 1U-wide "active" power modules that would come as a set.  The first 1U
module would have a power switch, a power indicator, two heavy duty 4-pin
female connectors (circular DIN?) that would provide power distribution to
additional MOTM cases, and a 4-way mult at the bottom.  The PowerOne supply
(3amp?) and a 960 distribution board would mount to the inside wall of the
case.  The second 1U-wide module would contain the power cord receptacle and
separate fuse holder (and the "no serviceable parts inside" graphic - for
those who order it assembled).  I think these would need to be separate
since the size of hole necessary to mount the currently used fuse
holder/receptacle on the 900 would not be feasible in a 1U panel.  This
module would normally mount to the rear panel of the case, but could mount
on the front if this is not possible.

A 1U-wide "passive" power module for additional cases.  It would have two
female power connectors (one for input and one for passthru to another
additional case), a power indicator and a 4-way mult at the bottom.  A 960
distribution board would come with the module and would mount to the inside
wall of the case.

A six foot long 4-conductor 14awg power cable that would have 4-pin male
connectors on each end.

What do you think?
