[ORDER] p0wr, a switchable Euro power inlet/outlet

Post by av500 » Tue Oct 04, 2016 1:36 pm

introducing p0wr, a switchable Eurorack power inlet/outlet.

use it to power a module outside of your rack for building, testing and debugging:

use it with a second unit to power a skiff from your main case:

switches -12V, +12V and 5V power lines, the LEDs can be jumpered for outgoing or incoming power.

two PCB set for diy builders including SMT male/female headers for board to board stacking:

complete kit with all parts:

Totally cool idea Vladimir.. Count me in for two sets of boards.. I have a small cigar box I could power with this very nicely! Cost???

kudos to James Husted aka ersatzplanet for the idea to power a skiff from the main rack!

Any benefit in adding fuses, if a primary use is for powering up new builds?

maybe, I don't know. after reading several threads about reverse voltage protection and fuses here on Muffs, I'm not even sure what to put.

So, like most people i will have no problems soldering this, but frankly, i do not know where to start sourcing parts.
I would greatly appreciate a Mouser cart.
I know most can be sourced at Ali but i kinda like Mouser and order there all the time, so this would just fit in.

And yes, i still think you could sell the kit :)

here is a suitable switch at Mouser: http://www2.mouser.com/Search/ProductDe ... P1T1B1M2QE

Reichelt: http://www.reichelt.de/Kippschalter/MS- ... OFFSET=500&

or you get 10 for $7 from eBay: http://www.ebay.de/itm/142077946683

I am apparently not clever enough to find 5mm LEDs on Mouser, I gave up :(

Here is an additional potential use: A dedicated switch for vacuum tube based modules like Metasonix, Trogotronics, etc. (I think Erica synths may require special power though.)

Those puppies have a huge power suck at start up. Having a dedicated switch will allow you to fire them up separately to the pack and reduce the huge surge by having multiple such modules.

so my question is do these have a max through power?

the MS 500M switches can do 125V/6A. I cannot tell you the exact power ratings for the PCB traces though, but I would guess powering 1-2 tube modules should be OK

I will enlarge the PCB holes for the next run....

Very nice,
just pin-header /jumpers on the front for current measurement i miss.

and i have not 3 eyes so i can't handle so much led's ;-)

Err..

:hmm:

Is this an idiot proof way for testing DIY modules?

i.e. will this stop the rest of my Eurorack from exploding to bits if I've arsed up my soldering?

no, it's not idiot proof. it really only switches the power rails to the front panel, if you generate a short circuit on your DIY build, you will short circuit your power supply as well... use at your own risk
