Author [ORDER] p0wr, a switchable Euro power inlet/outlet
av500
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:



order info in the next post

ORDERING INFORMATION:

PCB + panel + SMT header + matching female header: €20 + €5 shipping

complete kit: €35 + €7 shipping

(shipping as a registered letter, tracked)

to order, send me an email to vp (at) vpme (dot) de with your full shipping address, then I will reply with Paypal details.

toggle switch: MIYAMA MS-500M or the red equivalent from China/eBay/Aliexpress, see build guide for notes

WARNING: there are some RED CHINESE switches that have a very TIGHT FIT, the pins have a slightly larger size so you have to force them in - proceed at your own risk!



BOM/build guide attached. no Mouser cart, c'mon people it's 3 LEDs, 3 resistors and two shrouded headers.

awesome idea!!! This fixes a lot of problems.

Placeholder for ordering at least 1, depending on price.

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!

see above smile

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 smile

here is a suitable switch at Mouser: http://www2.mouser.com/Search/ProductDetail.aspx?R=1003P1T1B1M2QE

Reichelt: http://www.reichelt.de/Kippschalter/MS-500M/3/index.html?ACTION=3&GROU PID=7584&ARTICLE=13170&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....

I also have a few full kits for p0wr available now, €35 + €7 shipping
