Switch and 4ms Row Power: One less power brick

scanner_darkly · 2015-03-30T23:47:18.689Z

thanks @tehn!

AH lists them separately, and CV says "Power Brick 90W are sold separately as well. "
Maybe Switch could be sold without the PS? Especially if the row power PS does have higher specs.

Actually thinking about it some more maybe I don’t even need Switch as row40 provides 1.5A for +5V, could be enough without using external power - edit: should probably specifically mention this will only be the case for the black version, row40, as the white row30 only provides 0.5a @ 5V

yes, it does provide enough power, but having highly variable 5v demand using the same ground-return paths as the 12V system isn’t ideal. in some situations it can make ADC/DACs fluctuate, though you probably won’t notice this much.

unfortunately the Row Power system uses ribbons, which means shared ground return paths.

the best power supply i’ve seen/used so far by far is intellijel’s new system: http://www.intellijel.com/product/triple-power-supply-80w-3u-6u-busboard/

but, for my single row case, the row power works very well.

yeah, I’m thinking for a smaller setup specifically, like this one: https://www.modulargrid.net/e/racks/view/125863

i’m such a gieskes nerd
all those great modules and all i can see is that dep2b

scanner_darkly · 2015-03-31T03:14:25.316Z

can’t blame you! the man is a crazy genius.
took me 2 years to find dep2b, one of my favorite modules.
my modulargrid plan is out of date too, there are also 2 gieskes vu-percs now.

rad

need more space before i can get those
been swooning over em for a couple years

i need to slot a row40 into some simple 3u skiff and migrate everything over

Its a neat idea to use the Row power jumper for the Switch. Is it possible to connect power into Switch from the rear? I’m thinking a case with all the power cables coming in from the back would be nice.

tehn · 2015-03-31T12:05:28.744Z

you could hard solder an external jack and route it internally. i’ve considered doing this with my other case.

so stoked. tonight all my monome modules and power supplies arrived plus a mangrove and inteli unity mixer. awaiting ginko sampleslicer and already racked was phonogene optomix and function. not so strong in standalone category but depending on how much control i can render from ww+es+switch and my trusty 128…

yup i’m stoked.

michael_matos · 2015-06-09T01:48:42.775Z

Congrats dude. Sounds like a rad setup!

glia · 2015-06-09T01:58:00.896Z

def wanna hear this cluster

dude · 2015-06-09T21:59:51.233Z

i want to hear it too but no time yet.

tristen · 2015-09-08T01:49:58.681Z

Probably a silly question, but what do you mean by “jumper reduces your power brick count”? How do I do this? I’m new to modular. Thanks

tehn · 2015-09-08T01:52:22.757Z

i made a barrel-barrel connector so that only one capably-powered brick plugs into both the euro 40ms power and the switch power-- shown in the photo at the top!

tristen · 2015-09-08T02:36:24.756Z

Ah okay, thanks. I thought maybe you did something to the power supply itself.

dude · 2015-10-09T00:26:23.470Z

still really like this power config.

january · 2016-03-10T05:33:49.853Z

Anyone try this with the Row Power 30 instead/as well? I’m guessing both the row power 30 and 40 use the same power brick - so if I’m not mistaken, shouldn’t this work with that as well despite the lower 5v ability of the row power module itself?

tehn · 2016-03-10T13:45:39.467Z

this should probably be fine, but you may experience some weirdness if you start to light up a lot of the grid. worth testing out.

ppqq · 2016-03-10T18:32:31.271Z

FWIW, I’m using a Row Power 30 for my little sidecar. No problems here, though I’ll probably bump to a 40 to play it safe. (I’m done with power-related wierdnesses!)

I have a Row Power 40 for a 6U 84HP, with all the Monome modules, plus some Mutable Instruments and Harvestman (including a Malgorithm, which is a bit of a power bad boy in other systems), and I haven’t noticed any strange behaviour. So I assume a Row Power 30 should be enough for a 3U plus a grid.
