eliminating 9 volt w/out power supply, will this work?

[reaper]

i found this http://www.hackaday.com/entry/1234000383070996/ online and i was wondering if there is any reason i couldn't use these in a stompbox? i play alot of shitty ass venues (who am im kidding, basements) where outlets are at a premium and the circuit has tripped on me twice and i have a feeling my unnecessarily large pedal board has something to do with it. anyone tried this before?

uh. Would it last long enough?

Get yourself a suitable battery holder and a sextet of D-cells.  That will give you nice smooth 9VDC that should power up a handful of (non-digital) stompboxes in humfree manner for a while (at least the duration of a gig).

Would one of these (in the article linked to) power a pedal?  Not sure.  Need to see how many ampere-hours it can deliver and what the instantaneous current-delivery capabilities are.  There is an outside chance that it is really meant more for something where drawing 3ma @9v for several days is the intent (e.g., LCD display digital clocks).

As I mentioned in that thread  http://www.diystompboxes.com/smfforum/index.php?topic=46126.msg338572#msg338572

I would suggest that kind of battery  http://www.batteriesamerica.com/newpage4.htm

I like mine in the Peavy so much that I am slowly preparing a pedal board (on paper...) that would use that kind battery with 9V regulators for the pedals.

Hi
these also come in 5.5V 1F versions.  Two in series would power most pedals quite nicely. 
According to the web, 1F = 2.5 Ah  , so they'll last a VERY long time.  (10 pedals x 25mAh/pedal = 20 hours per charge).
Two cost about US$6 here in Australia.

But why not a NiMH battery?  Same cost, similar capacity.
