well, just for archival purposes, if using the wal-mart adaptor, the (+) side goes on TOP of the "tip" side!!!

done deal!!!

cant wait to use this this summer!!

thanks everyone that helped w/ the power hacks on the jb3, ya'll were the guinea pigs!!

thanks,
 bean

p.sp- i just electrical taped my jb3/universal power adaptor, for the jb3, and taped ity a couple times so the power adaptor doesnt go anywhere

pics to follow soon

and BTW, should a fuse be put inbetween the car adaptor and the jb3???

im too lazy to do it, so any answers would be ggreat!!

I didn't fuse mine, and no probs so far.  I did use a connector on both pieces so that I can reattach and still use/charge in the car.  I also used a tiny drop of super glue to make it stick at 4.5volt.  No super glue inside the unit, just a tiny drop where the end of the switch rubs the side of the case.

I do think taping is the reality of the business..it is also an impetus for artists to create studio CDs that are ART, not just another recording...    Fareed Haque  2-4-2005

nice, i am not too worried about the fuse thing, besides, i believe they are internally fused????maybe...

yeah, i just elec taped the thing so the 4.5v doesnt go anywhere, trust me, ive tried cause im obsessive like that ;)

I may have found another way to make a battery pack for the JB3 that does not involve a car charger.  I created a circuit out of radio shack transistors, resistors, and zener diodes that regulates the voltage to a perfect and consistant level for the JB3 and all this is powered by 4 D batteries.  On the computer model it works perfectly using the measurements taken from the JB3 however I am having trouble finidng the right zener diode at radio shack, they dont carry it, and I may have to order it (invariably in bulk).  which is a shame, but according to the computer model it will work.

hmmm, i have some diodes at my home, but i have no clue what they are???

any specific ##'s???

also guyz, once i get my 4-pins, on the walmart car kit, which end goes where???

what im saying is, once i snip off the cigarette lighter thing, there is an all black wire, and a wire w/ white writing on it, whats what???

thanks guyz,

chris v, once you got the wal-mart power line series like i now have, which is positive (+) and which is negative (-) for the 4-pin???

one side of the wire has a little white writing and the other doesnt at the cigarette adapter end........

thanks a ton bro!!

cool thanks, if you have a few I could probably throw a circuit together for you providing this model works

I did it, at least I believe so.  I used a 4 D-cell sled, then wired it in a circuit with a zener diode that regulates 5 volts, and pluged it into a radio shack adapta-plug "b".  It works all the time, except power on, but for best stability use the batteries every time you start and stop the recording.  So therefore i threw a switch on the box.  So I will test this out tommorow with rechargables and test it in the field on thursday.  If it works well i'll draw up plans for everyone.

Sounds like you already hit one of the snags - the JB3 draws too much current on startup for the diodes to manage.  The other one is that zener diodes are supposed to be noisy.  I don't really know what that means in this application but it's something to look out for.

As an alternative, if you throw another cell in your pack you can use a 5v regulator (and you'll be able to start up too)
