u2o Posted July 29, 2004 Report Share Posted July 29, 2004 Hi, I know NH3D is USB Bus Powered, and when connected it can be powered just by USB. My question is, can USB charge the unit as well? Also, is it possible that Sony will release AA battery case for this model?? Thanks. Quote Link to comment Share on other sites More sharing options...

u2o Posted July 29, 2004 Author Report Share Posted July 29, 2004 It's been answered before, and I know this guy's from the T-board.well thanks (although i dunno whether you know me over there affects your monotonious answers. oh and did i do/say something u didnt like??). i only asked here coz no-one answered this question in my thread of 'installing NH3d on english PC' thread, so i came over here thinking this might be more of an active forum. anyway thanks for the input. oh and btw, i did search. Couldnt find the answer though. Quote Link to comment Share on other sites More sharing options...
skyther Posted July 29, 2004 Report Share Posted July 29, 2004 Sorry, I'm just lazy. Chances are I was busy stuffing my mouth and typing with a single hand. But yes it's been answered before, the NH1/NH3D do not come with external AA packs, and the USB doesn't charge the Li-ion battery. Quote Link to comment Share on other sites More sharing options...
Qwakrz Posted July 29, 2004 Report Share Posted July 29, 2004 There is no technical reason that the NH1 cant be charged from the USB port, I just think sony wants you to carry the charger around with you. When I get my NH1, one of the first things I will be doing (after filling it up with music) is to see if I can modify a cable to allow either USB to be used on the charging cradle (should be a simple matter of linking the pins up to a cable) or making the USB cable charge the unit. USB = 5v, PSU = 6v. Worst case is a small charge pump to increase USB voltage to 6v for charging. The problem will be if the charging electronics are built into the cradle and therfore not allow charging unless the base station is used.

skyther Posted July 30, 2004 Report Share Posted July 30, 2004 Um, what's a 'charge pump'? I've heard of transformers, but definately not a charge pump. Quote Link to comment Share on other sites More sharing options...
u2o Posted July 30, 2004 Author Report Share Posted July 30, 2004 Sorry' date=' I'm just lazy. quote'] thats ok :smile: anyway i guess i'll have to buy a Sony 100-240V charger or similar then, although doesnt matter too much. Unit: 36000YEN Store Points: worth 3600YEN <<- i like how some japanese retailers do this. Charger: 2800YEN which can be paid by the points i guess i'll add one HiMD disc as well, which can be paid for by the rest of the points. BTW, Yodobashi.com is doing NH1 for 36800Yen or something, i might look into them as well. Quote Link to comment Share on other sites More sharing options...
jadeclaw Posted July 30, 2004 Report Share Posted July 30, 2004 Um, what's a 'charge pump'? I've heard of transformers, but definately not a charge pump.A charge pump works by charging a capacitor and then placing it in series between battery and output. That cycle is repeated a few 100000 times per second. This one from Maxim is a good example, what is possible: http://www.maxim-ic.com/appnotes.cfm/appno...ote_number/1021 Give it 2 D-Cells and you have a nice Lamp... :smile: Quote Link to comment Share on other sites More sharing options...
