Hey
could someone who is a little more electricly endowed post step by step instructions for modifying one of those walmart boxes to work for a UA-5?
thanks
adam

1. Take the supplied cable (coiled one) to Radio Shack.

2. Purchase a female to female adaptaplug cable.

3. Purchase an "M" tip for the said adaptaplug cable.

4. Have the sales clerk match the supplied cable for another "?" tip.

should get out for under 15 bucks, no hacking necessary!

oh yeah and let us know what the other "?" tip is, I need to get one too!!!

edit: the UA5's polarity is reversed (center pin negative), so you will just flip the "M" tip.

after cross referencing the included paperwork & Radio Shacks website, I have come to the conclusion that it will be the "B" tip. (but don't quote me!!!)

Tall Adam · « **Reply #2 on:** June 01, 2004, 05:49:46 PM »

yep it is the B tip that you want. before i go hook it all up and fuck shit up, do we know for certain that the B tip has the correct polarity and should be connected positive to positive?

Thanks for the help!

On a side note, if in the future I wanted to add an additional one of these walmart puppies to my rig (increased life, im only expecting to get ~4 hours out of each one, im using it for a M-100FX not a UA-5), could i simply purchase a Adaptaplug Y cable and hook up the second one while the first one is about to die or would i get an instantaneous surge of 18V if i did that?
thanks

i got a much older amp/volt meter (70s ish from when my dad was an electical engineer). but...stupidly i ask...what for?

leehookem · « **Reply #5 on:** June 02, 2004, 12:19:44 AM »

on either end of the female to female adaptaplug. it will say tip. for the end that plugs into the battery, line up the "+" on the B tip (battery is center pin positive). the ua5 is center pin negative (not sure what the m100fx is). if the m110fx is center pin negative as well, then line up the tip with "-" on the tip.

hope that makes sense.

edit: the great thing about the adaptaplug cable, is that you can choose the polarity on either end!

according to edirol, m-100 uses the same adapter as ua-5, so yes the polarity should be the same.

Just because the M100 uses the same adapter doesn't necessarily mean the polarity is the same. It probably is, but would be worth confirming before firing anything up.

good call, thanks for the input yall. i wont be getting the unit till tuesday so expect a plethora of new questions then when i have it in hand. thanks for the newbie support
peace

That would be what the meter is for... When messing with polarity on power cables it is always a good idea to double check... Keeps the smoke in, if you don't and you let the smoke out, it costs a lot to have the repair guy put the smoke back in.

I think mine is broken....

Ive had it plugged in to charge for 2 days and its still not full, thats not right I'm assuming. take it back to walmart?

Tony B · « **Reply #11 on:** June 04, 2004, 12:05:10 PM »

These will power an ODL 276 as well, won't they?

maybe the 4th green indicator light is not working, but it still may be holding the full charge.

see how long the battery lasts with 3 lights. i think there was another thread that someone had used thier ua-5 for 5hrs+ with this battery at 2 lights.

Tall Adam · « **Reply #13 on:** June 04, 2004, 04:07:04 PM »

i do think the 4th LED was broken on the old one, but i also think it was busted period. when i plugged it in the first time, it flashed green, the new one is solid red (the indicator of charging). in anycase, im almost positive this swapped one is good and for the 20 minutes of driving to replace it and the always friendly walmart customer service desk (riiiiiiight) im sure ill be happy with it.

Yup its broke, take it back get another one. Was a 7.2 volt one tho, but same idea... The one I had got really hot tho and that was another good indicator that it was hosed...

for 50 bucks and lightweight reliable power, cant complain

Ok guys ... i just bought a UA-5 digimod for use with my JB3 and im about to run out and get this battery crap taken care of ... Are these the parts I would need to make this thing work?

Chris K · « **Reply #19 on:** June 08, 2004, 03:57:54 PM »

yeah...except there is no hacking the cable since you are using the adaptaplugs.

here's how i did mine...rather unscientifically:

take the adaptaplug cable and fold it in half so the two striped cables are adjacent/touching and with both adaptaplug "ends" pointing up.

then put the "M" adapta plug on one side, and the "B" adaptaplug on the other side so both connectors are facing you. (you should be looking into to small circles at this point)

(NOTE...the positive side on the "B" should be the negative on the "M" plug...or vice versa...shouldnt matter...just make sure both striped cable halves are touching)

plug the B plug into the battery out....test for continuity...or just plug the M plug into the ua-5 and see if it works...

if all is well than charge the battery up to full and you are golden, pony boy

disclaimer...I am NOT responsible if you f*ck up and sizzzle your gear!

where's the fuse? you guys should really use inline fuses with power supplies.

Fuses?

Could doing this potentially fuck up my new UA-5. Cause if so I might shy away (i tend to fuck lots of stuff up)...

Tall Adam · « **Reply #22 on:** June 08, 2004, 11:04:24 PM »

in the end, my concerns over needing parallel power for hot swapping are laughable. ive had my m-100fx plugged in and running for almost 8 hours now and i still have about half a battery left

pretty fuckin sweet! i know this probably isnt an acurate representation of battery usage because phantom power and modifying levels and eq's and such, but it certainly is a confidence builder.

my mics come tommorow and then my rig is complete :-D thanks with all your help in the building process guys, ill post some samples once i start pullin my own tapes.

I recently bought an Oade 9v battery pack used. I've found that the "B" plug does NOT fit the output, the Inner Diameter of the plug is not large enough to fit around the battery's output pin. I had this occur with another generic 9v battery and I broke that battery figuring out the plug didn't fit right...

I'll try and figure out what the new plug is sometime this week, but work has got me swamped and its not a high priority right now...

according to edirol, m-100 uses the same adapter as ua-5, so yes the polarity should be the same.

when in doubt check the device itself............somewhere near the actual power jack it should list the voltage requirement and polarity (and sometimes the draw)

a la UA5 : DC in 9V - voltage
450 mA - draw
polarity diagram shows outside positive inside negative

most electronics devices have something like this...
