NOAC can run well with unregulated current ~5v?

scherzo · Post by **scherzo** » Sun Aug 14, 2005 8:36 pm

I understand that I can run anything higher than 5v into the Hip Gear as long as I'm not using the audio amp. Now what about power to my NOAC? Can I also just give it an unregulated current of around 5v and it'll be fine? Or is there a place on the Hip Gear I should pull 5v from?

oh yes, im runing the NOAC with 6V and it is fine.

Thanks. I really didn't want to risk frying it.

yeah. You can also (and should) use rechargeable NIMH AA batteries. thy pump ut 1.2V, but the ones I have go to 1.5 at full charge.

what kind are they?

duracell accu(something) I got em at wallmart. I had some before and the worked good, so I got some more.

could a noac (im usin neo-fami) run on 7.5 volts. i doubt it but would simplify my project a ton!

add a resistor!

i didn't think resistors affected voltage
i thought they affected amps

they effect current, wich in turn effects voltage. Voltage=Current/resistance.

use a 7805 from radioshack

well, wouldn't it affect resistance witch affects current which affects voltage? but thats to complicated. what resistor would i need to use. i cant do it by myself cause summer robed me of math ability.

no no...a single resistor wont bring it down to 5v, not if you put it in series at least. You need a voltage divider to drop 7.5v to 5v using resistors, if that's the way you want to do it then look it up on google.
The best way to produce 5v is defintely with a 7805 regulator. If you use a voltage divider, the output voltage will decrease linearly along with whatever voltage supply you were using to power it. If you use a regulator it will keep a constant 5v until it "drops out" because the battery voltage is dropping.

i dont want to use a 7805 bacause it waste power and i want as much playing time as i can get.
