MOTM

Hello Markk (is that with two k's?)

...and welcome to MOTM-dom!

MOTM is a great group to be a part of.  This is a very creative and intelligent
group of individuals.  Don't worry about asking questions, even if they seem a
bit "out there"; there's always someone willing to be helpful.  There's also
usually a lot of passionate viewpoints!  Don't confuse passion with arrogance
or bad feelings - most everyone means well (we all have our bad days, though).
Some of us have only a few modules, while others have nearer to 100 (I'm in the
middle).  It doesn't matter, everyone's given a fair shake; that's one of the
great things about this list.  And there's always something for everyone to
learn, yes? :)

** We have Paul to thank for this excellent experience. **

I also have some of Larry's modules - not bad from a guy who often works with
1000's of volts.. MOTM is a real step-down, eh? <drum hit>  His "fingerprints"
are also all over the MOTM-850.  (btw, joystick control, Larry??)

With all of your purchases it sounds like you'll be into some serious DIY,
which is great fun!  If you search the list history (as well as some of the
MOTM user web sites) you'll find interesting mods for some of the MOTM modules.

On to ferrite beads...

The MOTM part is: muRata BL01RN1 (alliedelec.com #711-4101)
A good (improved?) alternate is: Fair-Rite 2743004112 (mouser.com
#623-2743004112)

Is this what you were looking for?

As for power supplies...

I started with a MOTM-900 but have outgrown it's capacity.  It can power about
20-25 modules "safely" (maintaining a safety margin).  Power-One makes plenty
of bigger +-15V supplies.  I'm going the "DIY route" as we speak and selected
the HCC15-3-A which gives 3 amps, which is about 75-90 modules.  Is this big
enough for you?  The HDD15-5-A gives 5 amps, which is about 125-150 modules.
Is that better? ;)  You'll also need a few MOTM-960 distribution PCBs if you go
this route.  More info on Power-One:

http://www.power-one.com/resources/products/datasheet/lin.pdf

The new 500 and 600 series modules require a +5V supply as well as +-15V, so
you might consider adding either a MOTM-950 just for those, or a DIY solution
such as the HBAA-40W-A (5V@3A, +-15V@.8A) which is "larger" than the MOTM-950,
along with the new MOTM-990 6-wire distribution PCB.  It's a good idea to keep
the supply for the digital modules separate from your analog to "keep the noise
out".  (Hope I'm not bothering you with information that is obvious to you.)

Good luck!

Cheers,
George Kisslak
